Dual Display Problem?

[computerguy22]

Hi everyone, here's my problem. Set up Dual Display. Chose to "extend" the desktop, and it works nicely. Only problem is, when I do the command Windows + P, and choose computer only, my computer powers the monitor I DON'T want it to power, even though I configured the monitor I want to use as my "primary monitor". So, how do I fix this?

Using an Nvidia Geforce 8400gs.

Swap the cables going into the video card. You'll need to rearrange the screens in Windows afterward, because your left screen with be in the right, and vice versa.
