SPECIAL NOTES ON LCD MONITORS

The following symptoms are normal with LCD monitor and do not indicate a problem

NOTES Due to the nature of the fluorescent light the screen may flicker during initial use Turn off the Power Switch and

then turn it on again to make sure the flicker disappears

You may find slightly uneven brightness in the screen depending on the desktop pattern you use

The LCD screen has effective pixels of 9999 or more It may include blemishes of 001 or less such as a

missing pixel or a pixel lit all of the time

Due to the nature of the LCD screen an afterimage of the previous screen may remain after switching the image

when the same image is displayed for hours In this case the screen is recovered slowly by changing the image or

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

- 14 -

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

SPECIAL NOTES ON LCD MONITORS

The following symptoms are normal with LCD monitor and do not indicate a problem

NOTES Due to the nature of the fluorescent light the screen may flicker during initial use Turn off the Power Switch and

then turn it on again to make sure the flicker disappears

You may find slightly uneven brightness in the screen depending on the desktop pattern you use

The LCD screen has effective pixels of 9999 or more It may include blemishes of 001 or less such as a

missing pixel or a pixel lit all of the time

Due to the nature of the LCD screen an afterimage of the previous screen may remain after switching the image

when the same image is displayed for hours In this case the screen is recovered slowly by changing the image or

turning off the Power Switch for hours

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

ote 8) Definition of Crosstalk (Refer to the VESA STD)

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

SPECIAL NOTES ON LCD MONITORS

The following symptoms are normal with LCD monitor and do not indicate a problem

NOTES Due to the nature of the fluorescent light the screen may flicker during initial use Turn off the Power Switch and

then turn it on again to make sure the flicker disappears

You may find slightly uneven brightness in the screen depending on the desktop pattern you use

The LCD screen has effective pixels of 9999 or more It may include blemishes of 001 or less such as a

missing pixel or a pixel lit all of the time

Due to the nature of the LCD screen an afterimage of the previous screen may remain after switching the image

when the same image is displayed for hours In this case the screen is recovered slowly by changing the image or

turning off the Power Switch for hours

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

SPECIAL NOTES ON LCD MONITORS

The following symptoms are normal with LCD monitor and do not indicate a problem

NOTES Due to the nature of the fluorescent light the screen may flicker during initial use Turn off the Power Switch and

then turn it on again to make sure the flicker disappears

You may find slightly uneven brightness in the screen depending on the desktop pattern you use

The LCD screen has effective pixels of 9999 or more It may include blemishes of 001 or less such as a

missing pixel or a pixel lit all of the time

Due to the nature of the LCD screen an afterimage of the previous screen may remain after switching the image

when the same image is displayed for hours In this case the screen is recovered slowly by changing the image or

turning off the Power Switch for hours

ote 8) Definition of Crosstalk (Refer to the VESA STD)

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

- 14 -

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

ote 8) Definition of Crosstalk (Refer to the VESA STD)

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

ote 8) Definition of Crosstalk (Refer to the VESA STD)

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

- 14 -

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

Using The Right Power Cord

ote 8) Definition of Crosstalk (Refer to the VESA STD)

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

- 14 -

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

ote 8) Definition of Crosstalk (Refer to the VESA STD)

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

- 14 -

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

ote 8) Definition of Crosstalk (Refer to the VESA STD)

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

- 14 -

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

Plug and play

Plug amp play DDC2B feature This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD It allows the monitor

to inform the host system of its identity and depending on the level of DDC used communicate additional information

about its display capabilities The communication channel is defined in two levels DDC2B

The DDC2Bis a bidirectional data channel based on the I2C protocol The host can request EDID information over the

DDC2B channel

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

ote 8) Definition of Crosstalk (Refer to the VESA STD)

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

- 14 -

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

ote 8) Definition of Crosstalk (Refer to the VESA STD)

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

ote 8) Definition of Crosstalk (Refer to the VESA STD)

he calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh s follows Lmax -Lmin CT = x100 Lmin

here Lmax is the larger value of Gbkg or Lsh and Lmin is the smaller of the two To determine background and foreground levels (colors)first set the background to any gray scale or color level suitable for shadowing determination(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background Next display the box levels to determine the proper value for the background level Look for shadowing in any direction from box E Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test

One point only (the target) will be measured To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg) Turn on each box at a time Look for the case with the worst shadowing The box causing the worst case is the shadowing source or Bsrc Use Bsrc and the box opposite from it that lies directly in

- 14 -

the shadow path That is the target box or Btgt Note that box Eight be either Bsrc or Btgt depending on the shadowing conditions but typically Bsrc and Btgt will be a pair of opposite boxes AampC or BampD Btgt will only be displayed for aligning the LMD It will be turned off for the actual measurement

diams The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off

(Btgt is for alignment purpose only) Display the background only at level Gbkg Display Btgt determined in step 2 above Using the correct distance angle and measurement aperture align the LMD to the center of the Btgt Turn off Btgt With Gbkg set to its proper level measure the luminance (or color) Nextturn on the source box Bsrc Again measure at the center point of Btgt (without Btgt present) In this case the LMD will be measuring the shadowing level Lsh

Plug and play

Plug amp play DDC2B feature This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD It allows the monitor

to inform the host system of its identity and depending on the level of DDC used communicate additional information

about its display capabilities The communication channel is defined in two levels DDC2B

The DDC2Bis a bidirectional data channel based on the I2C protocol The host can request EDID information over the

DDC2B channel

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

Plug and play

Plug amp play DDC2B feature This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD It allows the monitor

to inform the host system of its identity and depending on the level of DDC used communicate additional information

about its display capabilities The communication channel is defined in two levels DDC2B

The DDC2Bis a bidirectional data channel based on the I2C protocol The host can request EDID information over the

DDC2B channel

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

Using The Right Power Cord

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is UL listed

and CSA labeled The voltage rating for the power cord shall be 125 volt AC

Supplied with units intended for connection to power outlet of personal computer Please use a cord set consisting of a

minimum No 18 AWG type SJT or SVT three conductors flexible cord One end terminates with a grounding type

attachment plug rated 10A 250VCEE-22 male configuration The other end terminates with a molded-on type

connector body rated 10A 250V having standard CEE-22 female configuration

Please note that power supply card needs to use VDE 0602 0625 0821 approval power cord in European counties

Plug and play

Plug amp play DDC2B feature This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD It allows the monitor

to inform the host system of its identity and depending on the level of DDC used communicate additional information

about its display capabilities The communication channel is defined in two levels DDC2B

The DDC2Bis a bidirectional data channel based on the I2C protocol The host can request EDID information over the

DDC2B channel

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

Using The Right Power Cord

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is UL listed

and CSA labeled The voltage rating for the power cord shall be 125 volt AC

Supplied with units intended for connection to power outlet of personal computer Please use a cord set consisting of a

minimum No 18 AWG type SJT or SVT three conductors flexible cord One end terminates with a grounding type

attachment plug rated 10A 250VCEE-22 male configuration The other end terminates with a molded-on type

connector body rated 10A 250V having standard CEE-22 female configuration

Please note that power supply card needs to use VDE 0602 0625 0821 approval power cord in European counties

Plug and play

Plug amp play DDC2B feature This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD It allows the monitor

to inform the host system of its identity and depending on the level of DDC used communicate additional information

about its display capabilities The communication channel is defined in two levels DDC2B

The DDC2Bis a bidirectional data channel based on the I2C protocol The host can request EDID information over the

DDC2B channel

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

Using The Right Power Cord

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is UL listed

and CSA labeled The voltage rating for the power cord shall be 125 volt AC

Supplied with units intended for connection to power outlet of personal computer Please use a cord set consisting of a

minimum No 18 AWG type SJT or SVT three conductors flexible cord One end terminates with a grounding type

attachment plug rated 10A 250VCEE-22 male configuration The other end terminates with a molded-on type

connector body rated 10A 250V having standard CEE-22 female configuration

Please note that power supply card needs to use VDE 0602 0625 0821 approval power cord in European counties

to inform the host system of its identity and depending on the level of DDC used communicate additional information

about its display capabilities The communication channel is defined in two levels DDC2B

The DDC2Bis a bidirectional data channel based on the I2C protocol The host can request EDID information over the

DDC2B channel

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

Using The Right Power Cord

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is UL listed

and CSA labeled The voltage rating for the power cord shall be 125 volt AC

Supplied with units intended for connection to power outlet of personal computer Please use a cord set consisting of a

minimum No 18 AWG type SJT or SVT three conductors flexible cord One end terminates with a grounding type

attachment plug rated 10A 250VCEE-22 male configuration The other end terminates with a molded-on type

connector body rated 10A 250V having standard CEE-22 female configuration

Plug and play

Plug amp play DDC2B feature This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD It allows the monitor

to inform the host system of its identity and depending on the level of DDC used communicate additional information

about its display capabilities The communication channel is defined in two levels DDC2B

The DDC2Bis a bidirectional data channel based on the I2C protocol The host can request EDID information over the

DDC2B channel

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

Using The Right Power Cord

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is UL listed

and CSA labeled The voltage rating for the power cord shall be 125 volt AC

Supplied with units intended for connection to power outlet of personal computer Please use a cord set consisting of a

minimum No 18 AWG type SJT or SVT three conductors flexible cord One end terminates with a grounding type

attachment plug rated 10A 250VCEE-22 male configuration The other end terminates with a molded-on type

connector body rated 10A 250V having standard CEE-22 female configuration

Please note that power supply card needs to use VDE 0602 0625 0821 approval power cord in European counties

Plug and play

Plug amp play DDC2B feature This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD It allows the monitor

to inform the host system of its identity and depending on the level of DDC used communicate additional information

about its display capabilities The communication channel is defined in two levels DDC2B

The DDC2Bis a bidirectional data channel based on the I2C protocol The host can request EDID information over the

DDC2B channel

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

Using The Right Power Cord

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is UL listed

and CSA labeled The voltage rating for the power cord shall be 125 volt AC

Supplied with units intended for connection to power outlet of personal computer Please use a cord set consisting of a

minimum No 18 AWG type SJT or SVT three conductors flexible cord One end terminates with a grounding type

attachment plug rated 10A 250VCEE-22 male configuration The other end terminates with a molded-on type

connector body rated 10A 250V having standard CEE-22 female configuration

Please note that power supply card needs to use VDE 0602 0625 0821 approval power cord in European counties

Plug and play

Plug amp play DDC2B feature This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD It allows the monitor

to inform the host system of its identity and depending on the level of DDC used communicate additional information

about its display capabilities The communication channel is defined in two levels DDC2B

The DDC2Bis a bidirectional data channel based on the I2C protocol The host can request EDID information over the

DDC2B channel

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

Using The Right Power Cord

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is UL listed

and CSA labeled The voltage rating for the power cord shall be 125 volt AC

Supplied with units intended for connection to power outlet of personal computer Please use a cord set consisting of a

minimum No 18 AWG type SJT or SVT three conductors flexible cord One end terminates with a grounding type

attachment plug rated 10A 250VCEE-22 male configuration The other end terminates with a molded-on type

connector body rated 10A 250V having standard CEE-22 female configuration

Please note that power supply card needs to use VDE 0602 0625 0821 approval power cord in European counties

Plug and play

Plug amp play DDC2B feature This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD It allows the monitor

to inform the host system of its identity and depending on the level of DDC used communicate additional information

about its display capabilities The communication channel is defined in two levels DDC2B

The DDC2Bis a bidirectional data channel based on the I2C protocol The host can request EDID information over the

DDC2B channel

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

Using The Right Power Cord

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is UL listed

and CSA labeled The voltage rating for the power cord shall be 125 volt AC

Supplied with units intended for connection to power outlet of personal computer Please use a cord set consisting of a

minimum No 18 AWG type SJT or SVT three conductors flexible cord One end terminates with a grounding type

attachment plug rated 10A 250VCEE-22 male configuration The other end terminates with a molded-on type

connector body rated 10A 250V having standard CEE-22 female configuration

Please note that power supply card needs to use VDE 0602 0625 0821 approval power cord in European counties

to inform the host system of its identity and depending on the level of DDC used communicate additional information

about its display capabilities The communication channel is defined in two levels DDC2B

The DDC2Bis a bidirectional data channel based on the I2C protocol The host can request EDID information over the

DDC2B channel

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

Plug and play

Plug amp play DDC2B feature This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD It allows the monitor

to inform the host system of its identity and depending on the level of DDC used communicate additional information

about its display capabilities The communication channel is defined in two levels DDC2B

The DDC2Bis a bidirectional data channel based on the I2C protocol The host can request EDID information over the

DDC2B channel

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY THERE MUST BE A VIDEO INPUT SIGNAL

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) andor

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK) This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present When there is no video input signal this monitor following a time-out period will automatically switch to an

OFF mode This reduces the monitorrsquos internal power supply consumption After the video input signal is restored full

power is restored and the display is automatically redrawn The appearance is similar to a ldquoScreen Saverrdquo feature

except the display is completely off The display is restored by pressing a key on the keyboard or clicking the mouse

Using The Right Power Cord

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is UL listed

and CSA labeled The voltage rating for the power cord shall be 125 volt AC

Supplied with units intended for connection to power outlet of personal computer Please use a cord set consisting of a

minimum No 18 AWG type SJT or SVT three conductors flexible cord One end terminates with a grounding type

attachment plug rated 10A 250VCEE-22 male configuration The other end terminates with a molded-on type

connector body rated 10A 250V having standard CEE-22 female configuration

Please note that power supply card needs to use VDE 0602 0625 0821 approval power cord in European counties
