n DDC (Plug & Play)This monitor supports the VESA DDC (Display Data Channel) standard.DDC is a signal standard for carrying out Plug & Play functions on themonitor or PC. It transfers information such as degree of resolutionbetween the monitor and PC. You can use this function if your PC isDDC compliant and if it is set so that it can detect the Plug & Play mon-itor.There are many varieties of DDC due to the differences between sys-tems. This monitor works with DDC2B.

3) Rotation (long height/width)The display can be rotated for a long height or width to suit the dis-played content.

Before rotating, move the display to its uppermost position. If the dis-play is rotated while it is set low, it will contact the stand and couldlead to damage.

The display can only be rotated through a range of 90. Applyingexcessive force may cause malfunction.

Do not apply excessive force when the cable is connected.

To set to long heightGently turn in the clockwise direction (to 90).

To set to long widthGently turn in the counterclockwise direction (to 90).

CHAPTER 2. CONNECTION, ADJUSTMENT, OPERATION, AND FUNCTIONS

1. CONNECTING THE MONITOR AND TURNING THE MONITOR ON AND OFFCaution:

When connecting, ensure that both the monitor and computer areswitched off.

Be careful not to overly bend the cable or add extension cords asthis could lead to a malfunction.

Cable storageIf necessary, excess cable can be housed in the stand.

1. Remove the cover.Gently pull the top of the cover towards yourself.

2. Run cable along the back of the stand.Pass cable in front of the stand, and then bring it through the back.

If the display is to be rotated, first house the cables with the dis-play in the long height position, so there is sufficient length whenthe display is turned.

3. Refit the cover.Be careful not to pinch the cable.

If the cover is hard to refit, do not force it.Check whether cables are trapped.

Caution: If the display is to be rotated, first house the cable, and thencheck while gently turning the display. If it cannot be turned,rehouse the cable with sufficient slack. (If there is insufficientcable length, rotation will be impossible. Forcing rotation maycause cable disconnection.)

1-1. Connecting the monitor to a computerThe accessory signal cable enables connection of two computers.(One analog and one digital connection.) To achieve an analog and digital connection for two computers, a

separately sold signal cable is required. The separately sold 2-input cable enables connection of two comput-

ers to the DVI-I input terminal.

When using the 2-input cable, set the connecting input terminal[INPUT-1] or [INPUT-2] to [2LINES] under the MODE SELECT-1Menu.

2 2

If connecting to a D-sub 15 pin 2 row Apple Power Macintosh, attach aMacintosh conversion adapter (commercially available) to the analogsignal cable.

Note: If connecting to the Sun Ultra series, a conversion adapter (com-mercially available) may be required.

n

n n

n Digital connectionConnect the digital signal cable to the digital RGB output terminal of thecomputer.

For digital RGB connection, the monitor has an input for connectingto a computer with a DVI-compatible output connector (DVI-D 24 pinor DVI-I 29 pin) and UXGA output capability.(Depending on the type of computer to be connected, the display maynot work correctly.)

Use the accessory digital signal cable or an NL-C04J cable (sold sep-arately).If using other commercially available digital signal cables, correctlydisplay may not be achieved. UXGA resolution may not be availablewhen using the NL-C01E digital signal cable.

Paying attention to connector direction, firmly insert the signal cableto terminal, and then tighten the screws at both sides.

Set the monitor as follows when establishing a digital connection with aPower Mac using an ADC-DVI adapter made by Belkin. (Operation hasbeen checked with the Power Mac G4 M7627J/A) Perform settings with the Power Mac power supply off.1. After connecting the power cord, turn on the monitor's main power.2. Press the e button and d button simultaneously, and while doing

this press the POWER button (i.e. turn the power on).

3. Set the input terminal to which the Belkin ADC-DVI adapter is con-nected to ON.Use the c button to select [INPUT1] or [INPUT2], and use the e dbuttons to select [ON] and [OFF]. Do not set to [ON] if you are not using a Belkin ADC-DVI adapter,

as this may result in incorrect display.

4. Press the power button, and turn off the monitor power.This completes setting.

n When connecting using a separately sold 2-input cableThe separately sold 2-input cable (NL-C03J) enables connectionbetween the DVI-I input terminal on the monitor and the two PCs.(One analog and one digital connection.)1. Connect the 2-input cable to the DVI-I input terminal of the monitor,

and then connect the analog signal cable (commercially available)and the digital signal cable to the 2-input cable.

For analog connection, use the commercially available analogsignal cable (both ends should be mini D-sub 15 pin).

2. Connect each signal cable to the computers.

Paying attention to connector orientation, firmly insert the signalcable into the PC, and then tighten the screws at both sides.

Note:

When using the 2-input cable, set the connecting input terminal[INPUT-1] or [INPUT-2] to [2LINES] under the MODE SELECT-1Menu.

The monitor connected to the 2-input cable by analog connectionmay not be automatically recognized and setup under Plug & Play.Perform storage of setup information manually.

1-3. Connecting a USB deviceThis monitor is equipped with a USB standard (Rev. 1.1) self-poweredhub.

Downstream (2 ports)Each of these ports enables connection of a USB device with workingcurrent up to 500 mA.

Upstream (1 port)This enables connection of a USB compatible computer or USB hub.

Note:

If a USB cable is required, please use the one included.

Before connecting, ensure that the shape of the USB cable con-nector is correct.

For information regarding the USB function (such as set-up) pleaserefer to the operation manual of the computer to be connected.

Some computers, OS and other devices may not be able to be acti-vated. To ascertain a certain device's USB compatibility, pleasecontact the manufacturer of the device.

1-4. Turning the power on1. Turn on the main power of the monitor.

When switching the main power switch on and off, always wait foran interval of at least 5 seconds. Rapid switching may result inmalfunction.

2. Press the monitor's POWER button.The power LED will light up orange.

3. Turn on the computer.

When a signal is input from the computer, the power LED lights upgreen, and the screen is displayed (After power is turned on, it maytake a little time until the screen is displayed.) If the input terminal to which the computer is connected has not

been selected, the screen will not be displayed. If necessary, per-form input terminal switching. (right column)

Notes: (when using an analog signal) If using the monitor for the first time or after having changed the

system settings during use, perform an automatic screen adjust-ment.

When connecting to a notebook, if the notebook computer's screenis set so that it is displaying at the same time, the MS-DOS screenmay not be able to display properly. In this case, change the set-tings so that only the monitor is displaying.

1-5. Changing between input terminalsUse the INPUT button to switch between signal input terminals.

When not using a 2-input cable

When using a 2-input cable

When selecting the input terminal connected to the 2-input cable, theinput terminal [INPUT-1] or [INPUT-2] is displayed, followed by the sym-bol for analog [-A] or digital [-D].(Example when connecting the 2-input cable to input terminal 2 [INPUT-2])

Note: When there is no input signal, [NO SIGNAL] is displayed.
