Windows 7: Radeon 5770 HDMI problem

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

What happens if you just plug in your HDTV and leave the monitor unplugged?

It could be an issue with your computer not reading it correctly when it is plugged in after it has booted.

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.

Can you boot into a repair disk?

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?

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