Good Morning, Running windows xp SP1. We are running a workstation that has stereo viewing capability. I need a monitor that has at least a 100Hz refresh rate for stereo viewing. I found one in the office that had its refresh rate set at 120 Hz. When I moved it over to the workstation in question it only shows a refresh rate of 85Hz (max). I installed the monitor driver on the workstation and also set the video card refresh settings. I still only can get 85 Hz max. The video card in the problem box is much better than the one I moved the monitor from. Any ideas? TIA Ron
