I have a Hisense 42" LCD TV (1080p) connected via HDMI to my ASUS K53E laptop and when I switch it to 1080p (second screen only) I cant see the edges of my screen, and it says my TV is a Hitachi 52" not Hisense 42". Also when I look at the "About this computer" section under Graphics it says Driver: Unknown and Experience: Standard. Im not sure what to do. Any help would be great, thanks. My OS is Ubuntu 12.10 64 bit edition btw.

This is a common problem called 'Overscan'. Can you please try browsing the overscan questions answered here already, and see if one solves the issue for you? This is probably a duplicate but you should confirm it first. – Tom Brossman Dec 23 '12 at 9:59
