I have the same TV and I don't use any mode lines to drive it, I just let the driver figure it out for itself. The only caveat is that the TV needs to be switched on and connected if you reboot so that the video card can probe the TV when X starts.<BR>
<BR>
I've extracted the edid data with "get-edid" and attached the results.<BR>
<BR>
Running that through "parse-edid" it generates the following:<BR>
<BR>
parse-edid: parse-edid version 1.4.2<BR>
parse-edid: EDID checksum passed.<BR>

I assume the 1360x768@60 mode above is the one the driver figures out for itself. It doesn't look like the panel is reporting a 50Hz mode.<BR>
<BR>
I'm curious, why do you need/want 50Hz? <BR>

Thanks for that. So I've now disabled Dynamic Twin View in my xorg.conf
file, and sure enough in the Xrandr gui the 50 51 52 Hz has disappeared.
However all it reports now is 60Hz. So I assume this is where I need to
start coming up with custom modelines to get it to run at 50Hz.
Unfortunately, my TV is "HD ready" - so it doesn't support 1080p and
there I can't use your xorg.conf. I'm running it at the native panel
resolution of 1360x768 and want to get it running at 50Hz. By the way,
if anyone already has figured out the modelines for a Sony Bravia
40V300A then I would greatly appreciate hearing from you.
Does it sound like I'm on the right track?
Aaron

Hi

> I turned off GPU Scaling in the nVidia xserver settings. This got rid
of the 50 51 52 Hz refresh rates, however now the only refresh rates
that show up are 60Hz. How can I figure out what the available refrsh
rates and timings are, so I can put the correct timings in xorg.conf?
No GPU scaling can't make 50,51 and 52 disappeared. It only prevent
the refresh being always 60Hz no matter what you choose.
For what timing to use if you want to set it manually, refer to my
previous post... There's a link to a xorg.conf that works perfectly
with Sony TV

util that returns the timings from the EDID? Is there some other way of
getting the timings from the EDID of my tv?
no
nvidia-settings let you play with the driver configuration. It comes
with the nvidia driver packages... And should be automatically
installed.
If not, the package name is nvidia-settings :)
