Ok, I instaled a diamond Stealth Radeon gfx card. and it works, but it is on some dual monitor thing. For example, my taskbar and icons are still located on my onboard port. but if I try to play a game it opens on on the video card port. I disabled the onboard and secondary video controlers in Device Manager, and I have also disabled it in my Display properties, in the advanced properties it dosent list me as having 2 monitors, but for some reason..It is still running through 2.

How can I make it So I only use 1 monitor, I would rather not have this Dual monitor thing going on. and Ive tried to simply diable it but it dosent work.
