1.11 General Troubleshooting
Problem
Possible Solution
No Power
Check if AC Power Cord is firmly plugged into DVI-VIDEOWALL-9X
If you are recovering from Power Outage, leave the device OFF for
a while and then power it ON again.
Off-Center Screen Image, Odd
Colors or No Picture
Make sure all cables are in good working condition and properly
connected DVI-VIDEOWALL-9X.
Configure the Output video resolution so that it doesn’t exceed
the native supported resolution of TV/Monitor/Projector
(Display). Usually a message of “Out of Range” is display on
TV/Monitor.
Every time you change the resolution of Input Source, wait 10 –
20 seconds. After the resolution is changed, the selection of Input
and the Display layout mode will return to default. Adjust the
Input source and Display Layout Mode to your requirements
again.
VGA Source can take up to 10 Seconds before it is recognized
Poor Quality Video
We suggest you don’t use T-Connectors to split your video source
into images displayed on two difference screens. This lowers the
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 in “State” for auto configuration.
Poor Linking
When the linking of the Serial Control cannot work, reboot
DVI-VIDEOWALL-9X to establish the link.
