Angry no 1080i on TVout with 8756

In 8756 the bug is back where a 1080i modeline is rejected. X drops to 640x480.

This is with an MSI 6200 card.

The modelines in question work fine with version 7676 and 8178. They were rejected for a version or so somewhere in between there.

8756 appears to completely ignore all modelines in my "Monitor" section in xorg.conf.

I tried setting UseEDID to false, as suggested in another thread. No joy.

Back to 7676 for me. At least it halfway works, and without performance problems, if I use the VSync workaround.

Does removing the ConnectedMonitor and UseEDID options from your X configuration, and explicitly requesting a "1920x1080" mode in the Screen section of your X configuration have any impact?

If not, then I'd like to see an updated bug report with those changes.

Thanks,
Lonni

It has an effect all right - the card tries to use CRT0 so I get nothing on the TV. However, it does recognize my old 1080i scanlines. It rejects the new 1920x1080.

If I put "ConnectedMonitor" back in, but keep 1920x1080, it does accept that mode. I don't know yet if that looks OK on the TV, because I'm connected remotely. Is that an interlaced mode?

Thumbs up Re: no 1080i on TVout with 8756

Answering my own question, looking at startx -- -logverbose 5, that IS interlaced. So it should work, and ignoring custom modelines isn't a major problem.


An important note here is that custom modelines (used to) provide a way to compensate for the TV's overscan, so this does represent a loss of functionality.


BTW, would it ever be possible for the "overscan" setting to accept negative numbers? I.e., compensate to remove overscan rather than to add overscan?

Now I'm crossing my fingers that the whole vsync thing is fixed in this version...

Custom modelines should still work fine. The only difference it seems is that you should not use the "ConnectedMonitor" option.

If I don't use ConnectedMonitor, I get no video, because it chooses CRT and I haven't got one connected. Only a TV. If I use ConnectedMonitor, no custom modelines.

So, my point is the same, there's a loss of functionality because I can't use custom modelines to compensate for overscan on my TV.

Try removing the "TVOutFormat" "Composite" line. Since you are using component, not composite, perhaps that's why the driver is getting confused and not seeing your TV.

According to the docs:

"The "TVOutFormat" option can be used to force S-video or composite
output. Without this option the driver autodetects the output format."

If that fails, try setting ConnectedMonitor to BOTH TV and CRT. It's possible there are bugs that are only exposed when you are running TV-only. If you trick the driver into thinking you have both a TV and CRT simultaneously, those bugs might go away. There's a chance that would solve your "sync to vblank" with xvmc problems also.

Removing TVOutFormat had no visible effect. Still chose the wrong display without ConnectedMonitor. There's no "component" option for TVOutFormat, "composite" is equivalent for that purpose.

However, I was able to replace ConnectedMonitor with the currently recommended UseDisplayDevice.

It still ignores custom modelines for TV out.

To specify both, wouldn't I need to be using TwinView? I suppose I could set it up to be mirrored.

If you specify none of the twinview options, I think it defaults to mirroring.

Hi, I had the same problem. I had to add

Option "ExactModeTimingsDVI" "true"

to the device section of the xorg file. 1080i still looks truely awful compared to windows though.
