AMD driver issue

I'm trying to connect my graphics card to an HDTV, which works just fine. It defaults to extending the desktop, and it sets the HDTV resolution to 1080i @ 30 Hz, which is not what I want. I can change the resolution of the TV. I can change the setup so that my desktop is duplicated on the TV. Here's the problem: any changes revert back in 20-30 seconds. I can't even permanently change the resolution of my primary monitor anymore, and I used to be able to.

There used to be a box that popped up asking if I wanted to keep changes. If you ignored it, the changes would revert. What I think is happening is that this box is not appearing. I can't click accept, so it changes back. I assume the dialog box is supposed to be there; can anyone confirm?

Any ideas as to a fix? I just updated the drivers, hoping that would fix it. It went from Catalyst 12.something to 13.1. No dice. What I did not do was wipe out any stray files or run DriverSweeper or anything. The card is an ATI 4850, if that helps.
 
Which catalyst version are you on? Your card is several generations old. Maybe they screwed up some drivers with holder hardware in the latest release and you just need to rollback your catalyst version.
 
I just updated to 13.1. It was also doing it on my previous drivers, which were most likely 12.4 or newer. I didn't check the version before I uninstalled it, but that's the most recent installer I have laying around.
 
My guess is your TV is automatically setting the connection to 1080i 30 Hz. Under "My Digital Flat-Panels" go to "HDTV Support". Try creating a custom HDTV format, or Adding 1080P60 format to Display Manager (NTSC) and Apply/Force Format. Alternatively there are predefined settings at the bottom that list 1080P60 standard. Select that and press Apply Format. If that doesn't work, try playing around with GPU scaling in Properties.
 
I'll give some of these ideas a shot tonight. Thanks, guys.

Also, make sure you have all other displays disabled first when you change the resolution on one.. I wonder if the OK box is appearing on another monitor.

That had occurred to me, actually. I tried duplicating my primary monitor so that both screens would have the same contents, and I tried disabling the HDTV. Both settings reverted after about 30 seconds. NOTHING is sticking.

Also try physically unplugging everything besides the monitor that isn't keeping your changes/popup box. I've done this before, I use 3 displays with 2 different profiles. Then plug in additional outputs as things go along.
 
This is not an ATI issue, this is a TV issue. I have 2 TV's, a dynex, and an LG, that do this too. I have tested with a multitude of video cards, Ati + Nvidia with the same results. I think it has something to do with the hdmi, because when I use the VGA connection 1080p works.

Try using VGA instead of HDMI and see what happens.
