Radeon 5770 HDMI problem

Hi,

Basically I use my monitor (DVI) as my primary display and my HDTV as secondary. It was working fine, until one day it starts messing up.

The regular monitor works fine until I plug in my HDMI. When I do that, it blacks out my monitor leaving the cursor frozen on the screen. The TV has no signal.

When I boot I can see it on both screens fine.

I understand this might be a resolution problem because it worked fine when I formatted my computer until i changed the preset to 720p (This worked fine before).

I have tried to:

-uninstall drivers and reinstall drivers
-use the previous drivers
-change hdmi cables

I do not want to format or send back in my card to XFX if I don't need too. Thanks

I will see the boot screen until Windows is actually running if it is running at all, and then the TV will have no signal.

Yes I can boot disks (ex repair disks) but sadly I didn't make one before that problem arose.

I don't mind formatting, but I'd rather not.

Did you try a different HDMI port on your tv or do you have access to another tv to try?

Yes I have tried that already. No luck. I tried most of the obvious thinngs already. Thanks

If you install over it, you can restore your data (but have to reinstall programs).

I will do that if I can't find any other solutions. Thanks.
