I am trying to set the correct display resolution for my Sony TV (KDL-32V2000, native resolution 1366x768) connected via HDMI to my HTPC running Ubuntu 12.04. I have a Intel Core i3-530 and Intel mobo (DH57JG), so no proprietary graphics drivers.

The problem is that I can't get the correct resolution to display on the TV. Initially I only had 1024x768 (or similar) as a maximum resolution, which was not displayed properly. I tried a few steps, including generating an xorg.conf (initially didn't have one) and adding the segment as described in this post regarding this particular TV. I couldn't get this to work, and at this stage have reverted to running without an xorg.conf. Another post suggested upgrading to kernel 3.5, which did give me a 1920x1080 resolution option. This results in the TV cutting off a fair bit of the edges of the screen.

My Dell laptop with ATI drivers recognises the TV screen and works well via HDMI.

Any idea how to proceed?

Got cvt and xrandr to add correct modeline with TV's native resolution, but only got a black screen. I think its a TV overscan issue similar to this persons problem forums.whirlpool.net.au/archive/1890106 –  user96195 Oct 30 '12 at 11:57

That is a rather nonstandard looking resolution which might cause some difficulty, my guess would be that you would need a modeline in your xorg.conf for it, I just did some digging on this searching for xorg modeline 1366x768 and found a forum post which looks like it will probably help you out, the question there is also about configuring a mode for a TV.
