Hello,

Having a frustrating experience. I had (or so I thought) the perfect setup; I just bought a new HDTV which I had connected up to my PC and have been gaming on. It's been absolutely faultless - until tonight.

I'm essentially running an HDMI from the HDTV to the PC and then the monitor is connected via DVI. The screen is duplicated. I then boot up my game move across the room to the couch with the controller and game. Easy.

Tonight though there's been an awfull screen tear. It's basically a single line tear near the top or (more commonly) the bottom of the screen. It's so jarring it spoils the experience.

I've managed to narrow down the issue; it's basically only happening in duplicate screen mode. If I extend the display the issue is gone. However this makes doing anything on the computer incredibly difficult as the monitor doesn't display anything and my mouse is nowhere near the TV. atm i'm just trying to nudge the mouse in right spot then going across the room to see if it's in the right place. Rinse repeat.

So essentially:
____________________________________

Duplicate display - terrible tearing.

Extended display - no tearing but can't see what I'm doing on the computer.

____________________________________

Does anyone know of any possible work around for this? It would be amazing if I could extend the display but somehow still see what's happening on the monitor. Though I gather this is impossible.

GPU sapphire 7950. Samsung Samsung UN40EH5000.

It's driving me loopy so any help would be much appreciated.

Thankyou.

I guess i'm at a loss. For anyone who experiences the same problem, I haven't found a solution but am considering a fix:

I'm thinking of buying a wireless mouse that I can use across the room so I can switch between extended and multiple displays. Not really the proper solution I was hoping for but will solve the issue.

Using Catalyst Control Center, under My VGA displays there will be a setting under Monitor Attributes called "Use Extended Display Identification Data"

Uncheck this and then select your resolution/refresh rate settings and the problem will be gone.
