1. Is there a setting that needs changed to watch full screen movie from laptop to TV, cables connected but picture is no larger than screen on laptop.looks like a box on the 32" screen. Also the picture will go blank after a few minutes but audio is continued at which time I must move the mouse to get pic,back. Thought it was the screen saver setting so it was changed from 15 min to 60 however that didn't help at all.
