1.14 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.
