Once the connection is made and both the TV and PC are turned on, all that is showing on the TV is the background from my monitor enlarged. I'm not sure if the screen resolution needs to be adjusted. I'm doing this set up in order to watch videos from Hulu and other site on my TV. My computer has an XFX ATI Radeon HD4650 1GB graphics card and the display manager is accessed via the Catalyst Control Center. I'm also running Linux Ubuntu 11.04 as my O/S as well. Since this is my first attempt at configuring the PC to TV set up, I'm not sure what needs to be adjusted so that the TV shows whats on my monitor simultaneously. Any advise is appreciated. Thanks.
