Just got a new Sharp Aquos LCD TV and am in the process of transitioning from my old tube TV (via s-video) to the new digital panel (via VGA).

I was able to find a modeline that enabled the panel's native 1360x768 resolution over VGA with 1:1 pixel mapping. The MythTV Gui looks fantastic at the higher resolution. The problem is, whenever I try to watch LiveTV or previously recorded programs, I get a black screen and the system locks up. I have to SSH in and reboot to get X back up and running.

The weird thing is, if I replace my xorg.conf with the xorg.conf.nvidia.tvout.example and plug the Myth box back into the S-Video port of the new tv, it works flawlessly (although noticeably fuzzier).

I examined the mythfrontend.log, and found that something is going wrong:

I've searched for some of the errors in the log, and can't find anything that's helpful. I've tried reinstalling the nvidia drivers, I did an auto-upgrade from R5F27 to R5F27 to refresh the install, I commented out the load "glx" line in my xorg.conf, and I tried switching between the internal, libmpg2, and xvmc MPEG2 decoders in Myth. I tried adding the following to the end of the xorg.conf file after reading it had fixed the GLX issue in other instances.

Code:
Section "Extensions"
Option "Composite" "Disable"
EndSection


None of this has solved the problem.

Currently, I have myth configured to use the full screen to play live and recorded TV.

Below is a copy of the xorg.conf file that works for 1360x768 but locks up with the above errors when playing live or recorded content.

Can anybody help me with this? I'd really like to be able to use my new TV! :? Is it worth it to try a clean install rather than an auto-upgrade?

I ended up doing a clean install, and the problem went away. Still not sure what caused it.

Teh only time I got a lock-up like the one you describe is when I had "realtime prioity" set ON. No matter what I tried, that darned realtime priority would cause a full lockup for everything I tried to watch.

Does it have digital input? HDMI will look better than VGA.

It does have dual HDMI inputs, but for some reason 1:1 pixel mapping is only enabled on VGA, so my DVI-HDMI connection resulted in overscan problems that I wasn't able to fix.

That's good to know. I'll cross Sharp off my shopping list. I
had downloaded the manuals and couldn't tell for sure if the
1:1 pixel mode would work for an HDMI input or not.

I will say, it is still a great TV - the difference between HDMI and VGA is not discernible to me... and, the 6ms refresh on this set is - the fast action scenes are much more noticeable on my friend's 8ms Samsung set... don't really notice it on this Sharp.
