Troubleshooting - No Sound／Speaker Noise／Abnormal Voice／Cannot control the volume

No Sound

1. Please check you are connecting with the correct input/ output ports with your PC and audio

device.

There are two ports that are commonly confusing:

i. Audio-in

port

(recognized as green port): It needs to be connected with PC if you want to play

audio from monitor by using VGA or DVI signal port.

ii. Earphone

jack

(recognized as black port): It needs to be connected with your audio equipment for

output.

Note: Earphone jack has no recording function.

2. Check your monitor with built-in speakers or you need to use earphone jack to connect with an

audio equipment to play.

3. If you want to transfer the audio source with video cable, please make sure you’re using

HDMI-HDMI or DisplayPort-DisplayPort cable to connect with your PC. Because VGA /

DVI switch will filter out audio source from HDMI or DP signal.

4. If your PC has no HDMI or DP port, please connect audio cable with your PC for help.

5. Check speaker setting on PC

i. Choose your monitor as default audio device

Go to Control Panel > Hardware and Sound > Sound > Change system sound

In Windows 10.

In Windows 7

ii. If you’re missing the monitor speaker in the list, go to Device Manager in Control

Panel. Uninstall and install the device again and check whether the audio input and output are

recognized by the audio device. Also, make sure the computer sound card driver is properly

installed and activated.

(NB/PC Realtek audio chip for example)
