resolution

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?
