[mythtv-users] Semi OT: xorg.conf and 46" Samsung LCD help.

[Jonny B]

Googling all night finally got me a working xorg.conf, but for
whatever reason, I can't get my frontend to output at 1920x1080. The
TV is a 46" Samsung LCD 1080p TV.
<http://www.samsung.com/us/consumer/detail/detail.do?group=televisions&type=televisions&subtype=lcdtv&model_cd=LN46A500T1FXZA>

According to the manual, with a VGA connection, the resolution is
supported, as is the refresh rate, but for whatever reason, 1600x1200
is the highest resolution that X will use. I can cycle through all the
resolutions in my xorg, except 1920x1080. The manual also lists a
couple resolutions for using HDMI input, but I am not yet using that
connection (yet being a key word).

Some things that I've tried: adding the modelines to the monitor
section (commented out at this point), which for whatever reason seems
to cause the image to be drawn halfway off the screen. Ths svideo out
option doesn't seem to make any difference at this point. The TV is
connected by a standard VGA connection. I intend to get a DVI-HDMI
adapter & cable at some point, but I also intend to get a nvidia 8xxx
card at some point. Currently using a 4000MX, which has been a
reliable card for the past 4+ years on this frontend. My nvidia
drivers are proprietary drivers from the
NVIDIA-Linux-x86-96.43.07-pkg1.run binary. Using OpenSuse11.0 with KDE
3. I've also messed around with the TwinView settings... at once point
I had it in 1920x1080, but panning in a 800x600 display. Also, at this
point xvmc doesn't seem to work. When I was running a similar xorg
with an older version of the nvidia driver (on opensuse 10.3) xvmc
worked, and I could use OpenGL for my rendering and whatnot, which
isn't working anymore. I suspect that is a nvidia driver issue though,
and isn't as much of a problem (I would like to resolve it, but I
think the better resolution will be an 8 series graphics card in a few
weeks)

Thanks for the help.
