Section 4: General Troubleshooting

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Problem

 

 

Possible Solution

 

 

 

 

 

Ensure that DVI-VIDEOWALL-4 is plugged in

 

 

No Power

 

 

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.

 

 

 

 

 

Make sure all cables are in good working condition and properly

 

 

 

 

 

 

connected to the DVI-VIDEOWALL-4 and displays.

 

 

No or Distorted Image

 

 

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)

 

 

 

 

 

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

 

 

 

 

 

 

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

 

 

Poor Quality

 

 

 

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.
