So, I and trying to use a trisync in a cab, but sometimes when leaving a game the desktop gets set to 800x600 (which isnt a problem the monitor can display it) but sometimes it gets set to something higher (like 1024x768) and then I have to unplug the trisync, and plug in an LCD to set the resolution lower. Is there a way to disable all the resolutions other than 640x480 in Windows?
