I have this video card and I can display the desktop connected to the S-video output but I can't duplicate the display on the computer monitor at the same time. I am running windows 7 and have tried various screen resolutions. I can switch back and forth between the two displays but can't duplicate them at the same time. The control screen will not let my apply these settings. The only place I can connect to the s-video output is using the windows function "connect to a projector"
