Default PC to TV issue - HELP! At wit's end!!

Hi guys,

I'm trying to connect my Dell 8400 w/ Windows XP Media Center to my Panasonic 42" HDTV via a DVI to HDMI cable.

At first it worked, but the resolution wouldn't go higher than 680 x 400 or so. I googled it and found out that I need to update my graphics card driver. Did so and it worked. But then, when I changed the resolution in the control panel, the screen went black. Now when I re-boot, the screen stays completely black, NOT EVEN THE WINDOWS START-UP SCREEN COMES UP!!!

I hook it back up to my PC and it works fine. Also:

I checked both HDMI ports on TV - they still work fine. I bought a new DVI to HDMI cable b/c I was sure that was it - nope. I tried changing the resolution to the lowest it could go and then trying it again - still no picture.

Can anyone help me??! I've tried everything.
Specs: Graphics card: ATI Radeon X300
TV: Panasonic 42PX60U

Appreciate any ideas.

- Daniel

dual monitor it and mess with the settings with the regular monitor.

or reset your CMOS,

you would need you motherboard/PC manual to do this.

I didn't even think about dual monitoring it. Thanks, that should at least give me a clue as to what's wrong. I'll give it a try tonight and post again if I need help resetting my CMOS.

Also make sure your tv can handle whatever resolution your setting it at.
