So I have been wanting to try out my laptop on a HDTV, as it has a semi-good graphics card. Running an ATI Radeon 4200HD, it has 256MB of RAM, so it has a fair punch. However, the screen res does not support 2966 X 1200 automatically. I have used the AMD Catylist CP, and still have no luck. 2966 X 1200 is the minimum on the TV I have, and the option to downsize it on the TV itself requires a connection with the laptop. I have gotten a signal when at the boot screen, and when logging in. It looks amazing actually. Problem is, once I have logged in, it cuts to black. When I apply the settings for max res, it says it req's 2966 X 1200. Any manual solutions to this? Havent found any others around the forums, AskUbuntu, or google itself. Thanks a bunch!
