Section 4: General Troubleshooting

Problem

Possible Solution

No Power

 Ensure that DVI-VIDEOWALL-4 is plugged in

 If you are recovering from power outage, accidentally unplug the

adapter or other power surge conditions, leave the device off for

a while and then power it on again.

No or Distorted Image

 Make sure all cables are in good working condition and properly

connected to the DVI-VIDEOWALL-4 and displays.

 Configure the output video resolution so that it doesn’t excess

the native resolution of the display. ( in this case, the message of

“out of range” is usually showed on your screen)

Poor Quality

 We suggest that don’t use T-connectors to split your video source

into to images displayed on two different screens. That will lower

output video quality. Use a distribution amplifier instead of

T-connectors.

 Make sure the video source is not compressed and maintains the

highest native resolution.

Wrong Color

 Press “Color Balance” key for auto configuration.

Auto color configuration only works at VGA and YPbPr inputs.
