Hi,
I currently have an ubuntu 12.10 machine set up in my living room connected to a TV. The TV only really supports 1280x720 but can scale to 1920x1080, losing pixels. My problem is, although I have set (with gksu amdcccle) the resolution to 720p, when I switch the monitor off and on again, the resolution resets to 1080i.

Is there some way to disable the higher resolution? Or simply force the resolution to stay down? Below are my lspci output and xorg.conf if they are any help
