Tv as second monitor not showing up as option with radeon X850XT-PE in Ubuntu

I'm using a crt tv as a second monitor (yes I know, it's 2012) I have an s-video cable coming out of the video card, which then connects to an rf adapter, which connects to the tv through a coax cable. The tv is not showing up as an option as a second monitor when I click "detect monitors" under system settings -> Displays. During the boot sequence everything shows up on the tv as well as my main monitor until ubuntu loads, then it only outputs to my main monitor.

I have a fresh install of Ubuntu 12.04

here is the output of lspci
