The HDMI cable works when no driver is installed and before windows full starts up, not sure if that makes a difference. It also worked fine on the old computer (with the same video card but different driver).

Wonder if I could just keep going back driver versions until I, maybe, find one that works.. I shouldn't have to do that though

With the Catalyst Version 11.5, you should have no problem running both HD 6770 and 5770. I have triple video cards/triple monitor set up that work without a glitch. Check your power supply, if you power supply doesn't provide enough power to the graphic cards it won't work. You need at least 750W 80%+ to run the set up.

I have HD 6770, HD 6870 and HD 5770 video cards.
