Sapphire Dual-X 7970 Resolution problems, certain games.

post #1 of 3
Thread Starter 
Alright, so here's the deal: I recently bought an HD 7970 from sapphire and had been running all of my games on my Insignia 1080p TV at it's native resolution prior to the install of this card. Before hand, I was using a crossfire 7770 set-up which worked fine, albeit with terrible frame rates in most games. This is what prompted me to upgrade in the first place, and though the frames improved as expected with the enthusiast-bracket card, I've been having problems getting my games to display at the TV's full 1080p resolution! In fact, in some titles, the max resolution showed in the menus is 1280x768. This isn't a problem in windows and other games, however. The ones in particular that have demonstrated this annoyance are Crysis 3, Tomb Raider 2012, Metro 2033, and Deus Ex Human Revolution. I've tried to force 1080p, but this never seems to work.

I've tried a few things besides forcing the resolution to fix this problem, but everything has failed so far. I've swapped HDMI cables in case i had somehow gotten a low quality product, reinstalled the catalyst suite, and searched around google.

Also note that I have successfully ran all of these at the desired 1080p resolution on a friends TV. I don't think it's an issue with my TV thoguh considering that my crossfired 7770s and the nvidia 610 I had before that never gave me this problem. I think it's probably software of driver related, but I could use your help guys.

It's not a scaling thing is it? In windows the monitor resolution actually says 1080p?

If it is a scaling thing you can fix it by going into CCC | My Digital Flat Panels | Scaling Options - and make sure your TV is selected in the drop down then set it to 0% scaling.

Actually, it was. I just had to tick the box for "Use these scaling values" and everything is working fine now. Thanks for leading me to my answer.
