Dual Display and Counter Strike

[McNuggets]

OK,

I just hooked up a dual display system to my computer but when I try to run counter strike it says that I my video card doesn't support Open GL. My primary AGP one is a GeForce II Prophet and it worked fine before I installed the new video card. Is there any way to disable the other when I'm just playing CS?

Sure. Although my setup works fine for CS with dual displays. Anyway, to disable the 2nd when playing, just right click the dtop and get into the display properties, then settings, select the 2nd monitor and uncheck EXTEND MY DESKTOP onto thie montior.
