I've been banging my head against this one for a while. Followed multiple forum threads encouraging me to modify xorg.conf files, usae xrandr commands etc. Nothing has worked. First time Ubuntu User wanting to squeeze some life out of a 3 year old laptop (Vista has become frustratingly slow).
I'm using Ubuntu 12.1 on a HP laptop connected to a HD Ready (720P) screen via a VGA cable. Don't have HDMI/DVI etc. The laptop is a HP with Intel® Core™2 Duo CPU T5670 @ 1.80GHz × 2. ATI radeon graphics card ("unknown" according to Ubuntu).
MS Windows Vista displays fine on the TV but only get two 4:3 options on unbuntu. This is a real pain as I want to use this as a media device, laptop lid down. I can make VLC correct dvd playback but when viewing online video I'm forced to view a letterbox across the middle.
Can anyone help. How can I get an appropriate 720P output from this Ubuntu install as I do on Windows? This is the only thing stopping me loving Ubuntu!!
