ExactModeTimingsDVI and grey screen

[spoon]

My system is connected to the HDMI of my TV, via a DVI to HDMI cable. 640x480 works perfect, however the EDID information reports that the TV can do 1920x1080, 720x480, 1280x720, 1440x480. Of course if I set X to use anything beside 640x480 I get overscanning. So I tried setting "ExactModeTimingsDVI" to a "true" or "1". The problem is the screen turns grey and my windows manager ( twm ) doesn't come up. I'm guessing I'm not using it correctly, but I'm not sure.

Any feedback on what I'm doing wrong would be highly appreciated.

Have you tried using the TVOverScan X option? That's what was meant for dealing with overscanning, not ExactModeTimingsDVI. Also, why are you using the ConnectedMonitor option?

I'm using "ConnectedMonitor" because when I first started X, nothing appeared. "Video 7" appeared on the screen as if it lost signal, like it was using VGA instead of the DVI. Once I added the option, I received video.

I haven't tried "TVOverScan" yet. I was under the impression that it was used for the TV-Out ( S-Video or composite ) connector and not DVI.

You can try using xvditune to tweak a modeline to remove the overscan.

I have, however I can't shrink it enough. I might have to try Powerstrip if get better modelines.
