9.4. Picture is not displayed or distorted
Check the cables
Due to the high data rates, the cables must fit very well. DVI connectors have to be
locked with screws, no tensions or breaches are allowed. If your source or display
has more connectors then make sure that the proper interface is selected.
Although the router is equipped with DVI-I connectors, analog signals are not
supported. You cannot use VGA cables with DVI-VGA adapter plugs.
Check the crosspoint matrix
Check the connection between the input and output port either on the front panel or
from web or the control software. Check whether the output is muted or not.
Check EDID related problems
Maybe your display device is not capable of receiving the sent video format. Try
emulating your display device‟s EDID to the source. You will find help on this
process in section
4.4.1
about EDID router operation with control software on page
34
, or in section
5.4
about EDID router operation with built-in website on page

.
If you get a picture now, you have an EDID related issue, please read section
1.5
about understanding EDID on

for more details.
Check the source
Check whether your source is powered on and configured properly. The HDMI
output can be turned off on most DVD players. If the source is a computer, then
verify that the DVI output is selected and active. Try restarting your computer; if
you get a picture during the booting process, you have to review the driver settings.
