When I set the refresh rate to 70 or more, the display becomes fuzzy on the monitor, and thus I have to set it at 60 to see clear. Why is this? When I had my 5700le with Forceware 71.20, everything was fine at 75. But now I have this 6800 with the most updated driver (forceware 81.95) and the refresh rates seem wrong. Is it my driver? Anyone else using the 81.95 and experiencing this problem?
