Im going to be getting a 42" plasma for my computer as a monitor and wanted to no which setting i need to set so i can have the whole screen on the monitor....
You probably have a sound jack just below the VGA port on the tv.
You could get a Y-splitter for the computer and an Audio cable.
To have sound on the speakers and tv speakers.
For my 32" I just right clicked on the desktop and adjust as needed.
