TROUBLESHOOTING
Problem
Recommendations
No power
Check if you firmly plug the AC power core into the VW-1312
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/Erratic video
Make sure all cables are in good working condition and properly
connected to the VW-1312 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)
Every time when you change the resolution of input, please wait for
10-20 seconds. After the resolution is changed, the selection of input
and the Display layout mode will return to default. So, please adjust
the input source and Display layout mode to your requirement once
again.
When first time catching VGA input, it has to take 10 seconds to
display the VGA source successfully.
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 in “State” for auto configuration.
Auto color configuration only works at VGA and component inputs.
Poor Linking
When the linking of the serial control cannot work, please reboot
VW-1312.
