Hey guys, I'm getting no video from my dell 520 to my hdtv through my dvi on computer to my hdmi on hdtv...for a short time I got video but the screen would blink, then nothing. If I replace my X1300 pro with an radeon HD 2600 xt with a hdmi port, and upgrade my power supply would this get my video signal to my hdtv. As it stands now all is working well vga to vga but my picture from my media center not so clear. Im asking because I really do need a little help from people who know...thank you all in advance.
