A Post from that thread you sent me,
"this thread is getting old, but I feel it's misleading.
All 3 monitors are running different resolutions and the 24" is also a different aspect ratio.
When you turn on surround in the control panel, it creates 1 resolution that covers all 3 monitors.
From left to right: 17", 24", 19" running on 2 560Ti"
Question answered, thanks a bunch, was worried I had to deal with a very ugly fuzzy looking right monitor
