I got my PC about a year ago and it came with a 27 inch monitor. I also have a early 2011, 13 inch MBP. Whenever I try to hook up the macbook pro to the 27 inch monitor, I need to underscan to have it show right. The monitor is set at 1080p and so is my macbook. The monitor seems to display my PC perfectly fine, without fiddling with underscanning or anything. So I was wondering? Any way I can fix this so I dont need to underscan? It makes my whole desktop blurry so I dont like it... Any ideas? I have already tried all the resolutions my macbook pro offered me.
