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.
