I just bought a Toshiba Regza 47 inch widescreen lcd display hd tv. I know that it displays higher resolutions. I have a laptop that that has a vga output so it can display onto a secondary monitor. I wanted to use the tv as a secondary monitor or main. I can get the tv to use as an extension from my laptop. but heres the problem My tv resolution can't go any higher than 1024 x 768. If any higher then there is no display and my tv say's unsupported video signal.
I tried all the higher resolutions and no luck. 800 x600 works fine.
my tv has a vga input.
what is wrong
