I've read that if an in an OpenGL game you select 1280x1024 (or 1280x960) and the glasses are activated, it will actually run at 640x480 with 120Hz of refresh rate. So your monitor must only support 1280x1024 as resolution (any refresh rate) and 640x480@120Hz. My monitor (Sony CPD-100GST - 15") should support 1280x1024 (it's on the manual, and however I used to set 1280x1024 with my old Tseng ET6000 on the same monitor), but it doesn't appear as available res. Don't know what I gotta do?
