So I've been gaming with my computer hooked up to my hdtv for awhile now and its been fine (gtx 460se windows 7 AMD Phenom 910e) at 1920x1080p. However, last night i think i pressed something on accident that made everything almost zoom in just a little bit to where everything is sort of cut off around the edges. About a half of my taskbar at the bottom of the screen is cutoff. I've looked online and found something called underscan/overscan but that didn't seem to do it and I've fiddled with all the settings in the nvidia control panel that I could think of. Any help or suggestions would be appreciated. It's pretty annoying.

Get a hold of your TV remote and make sure the picture type isn't set to Zoom1 or some bullshit. Hopefully it's a simple fix like that.

On most HDTV's you can press a button on your remote called screen, or p.size, or similar that will change the over and underscanning. I had the same issue and it's just poorly auto optimization and scanning with Nvidia's control panel since I had no issues with this on AMD's catalyst control center on the same TV. Just make sure your HDTV is manually set to a static screen size and not dynamic.

Alternatively you can manually change the resolution to fit the screen in the Nvidia panel.

Damn thanks alot guys. It was that button "p. size" on my remote that I guess I had accidently pressed. Didn't even know that existed. Thanks for the quick responses that seemed to do the trick
