Hey guys, I am running Win7 Ult 64 bit. I just one a little TV from a raffle. Its a 15 inch 1080i composite TV. My main monitor is a 25 inch 1080p monitor. Because the TV is composite and not HDMI, I am using the VGA port to my onboard graphics, and then using my 5770 for my main HD Display. It seems to be working fine, however my main display, which although is 1080p resolution, seems to be scrunched. It is like I am not using the full monitor. There is a thick black border around the screen of unused space. My HD monitor is set up to be my main display.
Are you using HDMI on the main monitor? Yes? Then go to catalyst control center, click around till you find the display menu (cant give exact directions cause IDK what version you are using; AMD changed it recently), or the overscanning menu, or whatever, and turn off overscanning. There will be a slider, set it to 0.
