Troubleshooting Q & A
There are green red dots on the local moni-
tor.
This is an EQ problem on the input source. Adjust
the EQ knob until the dots disappear
There is no image on the monitor.
Check the following:
Cable Length
Cable Quality (Low skew FTP cables perform
better than regular network cables.)
Adjust the EQ knob slowly until the image
appears.
The output of display has noise or occasion-
ally flashes.
Check cable distance.
Check cable quality.
Slowly adjust the EQ knob on the HDMI-1-R
until the image appears. It is best to use a
pattern generator instead of the source to
perform this adjustment.
Check for excessive RF interference in the
room.
