I've recently purchased a DVI to HDMI cable in order to extend my display to my LCD TV. When I attempt to plug it in, with my computer turned off, and boot it up, my operating system won't load. It extends the display, but before it finishes loading, I see a flicker, and the display stays like that forever. When I attempt to plug the cable in with my computer on, everything freezes the second I plug the HDMI end into the TV. I suspect that this has something to do with my Catalyst settings. I've got an ASUS motherboard, and it comes with a browser you can use before booting up your OS. This browser extends beautifully onto my TV. It's when I boot up W7 that things begin to freeze. Does anyone have a suggestion I could attempt?

Does your current video driver support extending your display? Would you run a pittest and post a link to your results back in this thread?

I'm running the latest ATI Catalyst (10.6).
Here's a link to my test.

Have you tried starting with just the TV? The output from the card might be wrong, causing an issue. Also, I know that back when, not all HDMI cables were compatible. Not sure if ATI has the 59 cycle problem of some Nvidia drivers. I'll think on it.

I've tried hooking it up straight to the television, and it still won't work. I'm beginning to wonder if the HDMI cable could be defunct.

I doubt it...

It works until your driver loads so I'd say it works.
Lets see what RAH comes up with.

I've just tried hooking up my laptop to the TV using the HDMI cable, and this setup works. I guess the problem must be found in my display settings. I'll try to play around with them some more to see what happens.
