I have a Viewsonic G90fb running on a 9600 Pro and have been using if for 2 weeks and am loving it. Today something happened so that i cannot raise my refresh rate of 60hz. When I do it through the display properties it says that it changes but when I go through the viesonic menu and check the view monitor it shows it at 60hz. i can lower it below 60hz but not above. I have reinstalled my videocard drivers and monitor drivers many times to no prevail. Anybody know what is wrong and how to fix it?
