Signal Corruption - Setup Issue
I am trying to use DVI input to a projector from my linux box but the output is very noisy. The same projector can be used from a windows box.
Linux box base intall RH7.2
Kernel upgraded to 2.4.20
Nvidia GeForce FX 5700
XFree 4.2 (with RH install)
Attached are my logs and Config files. X run with logverbose 5.
I see a noisy line on the left hand side, top to bottom. The monitor does not provide frequency information so I added that myself (random values). Without that could not have a signal on the projector.
Re: DVI output to the projector has noise
Adding to the information in the first post.
System still running I plugged out the DVI from the projector to a DELL-FP. I could still see the noisy line. Rebooted; this time with the DELL-FP on the end of the DVI cable.All works well.
Hence the setup with the projector itself is wrong. The signal shows noise on a working FlatPanel as well.
===== Additions ====
Did more tests. This time plugged out the DVI from a working DELL-FP and plugged in to the projector and the output is good.
So the problem is with the initial setup between the projector and card. I tried to use Option "IgnoreEDID" "True". That does not help. What else can I do.
