Since switching from a tube monitor to a Samsung 204B Flat Panel, every once in a while, sometimes each time you power up, I get the warning from the Flat panel that the settings are not optimum. When I check the refresh rate in MCE, it has 75 instead of 60 as last set. The check box for hiding refresh rates no available on the monitor, is greyed out. The video card is a 7800GT, the drivers are 8198. I tried to install 9147, but that made the video overlay green, I got video sound, but a flat green screen. So I went back to 8198. I tried to update the monitor driver but that did nothing for me. The Nvidia control is installed, but clicked on 'use Windows settings'. Anyone every encounter this before?
Any help thoroughly appreciated! Thanks....Steve
