i have a question about using a big screen too. I have a Gigabyte 5830 HD grafics crad with 1GB of DDR5 running at 128 bt/s works perfectly for everything but games...... the screen just goes black. But I want to try to play games on a 50" Panasonic Plasma TV so my question is. I have everything hooked up and I'm using it now.... can't play games. Is there a way to get it to work? I was thinking maybe the output signal was not strong enough to support the graphics of my games and maybe I need a higher performance card or a second in addition hooked up in crossfire any help or advice is greatly appreciated.
