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!

What does the Catalyst Control Panel report as your set resolution? –  Travis G. Feb 1 '13 at 21:21
The ATI Radeon HD4000 Series product line is mostly from 2008, for high end that is. Also this seems to be a low end graphics solution which might be based on an even older design. I strongly doubt that it provides "a fair punch". Resolutions beyond 1080p were specified in HDMI with version 1.4 in 2009. Almost all cards at that time maxed out at 2560x1600. What is the brand, name and model number of the TV? 2966x1200 is rather like the maximum resolution, it surely can be feed with 480p, 720p and 1080p. –  LiveWireBT Feb 1 '13 at 22:07
Its a Panasonic Viera, and I cant access the input res without having an input to edit. It says I can edit the required res on the TV itself, but I cant access it without having a signal to edit. It does pack a decent amount of power (For a laptop [in the 200-400$ price range]), and is pretty reliable. Nonetheless, I have gotten a Dell Inspiron 5100 with a Pentium III 800mHz to work on that TV without having to edit the settings (The Dell is a 13 year old dinosoar). Any other suggestions? Also, it says the res for the "Unknown Source" (TV) is set at 1633x736 (Something like that). –  That Guy Who Always Needs Help Feb 2 '13 at 1:43
