edges getting cut off on my monitor

I solely registered for the purpose of thanking celockwood and if anybody else should come by this way with the same problem. Just my completed my first gamer PC.
Graphics Card: NVIDIA GeForce GTX 560 SE (was not the problem of-course ^^)
Screen : AOC 24`` HDMI
Did just like celockwood said and it work 100% for me. If you should ever read this, THANK YOU A 1000 TIMES!

I had the same issue and for me it was a monitor thing. I had to go into monitor settings and auto adjust image. May not be the solution for everyone but was for me.

alan333's fix fixed mine too after I hooked up a KVM switch

Just registered to say thank you for the useful ideas. I had the same problem for two years and I wasn't too hopeful today either when trying "for the last time" again. Found this thread with some new ideas I haven't tried yet, and it WORKED! The problem with the edge truncation is on the monitor side, no woder I have been trying in vain with the screen resolution control panel. I have a Sony Bravia 32" (really old, like 8 years) and the trick that fixed it was to press the "Home" button on the remote control, go into Settings, then Screen, and change "Display Area" to "Full Pixel". Now I can watch videos in VLC (especially the ones that demo computer screens) without any of the edges cut off. Very happy. This made my day!
