Troubleshooting
1. No video signal is displayed on the monitor.

are securely connected.
1.2 VGA cable was not attached to computer during boot up process. Please
make sure the VGA cable is attached and reboot the computer.
1.3 Please ensure the power adapter is plugged into the Receiver.
2. Video signal is foggy or un-cleared on the screen, please check VGA connector,
or the VGA resolution is too high for the length of cable being used. If the issue
is related to VGA resolution, please shorten the CAT5 cable length or lower the
VGA resolution. It is highly recommended to use “optimal CAT5 cable length”
to get the best video quality and don’t waste unnecessary CAT5 cable.

length up to 500 feet approximately. Use a shorter cable will
not make the VGA resolution become higher.)
