Hello all, my rig has 3 monitors running off 2 cards.

4890 running at 1920x1080 and a
5450 running 2 at 1440 x 900

My motherboard is pants so both cards are running at the slower rate of x4 specified by my second slot. The main slot is x16 but the motherboard defaults to the slower value when more than one is used.

For playong games i would like to disable the side monitors run by the 5450 and only have the main screen running on th 4890 at x16.

Is there a way to do this in windows without having to go through bios or remove the card?
