Ok, totally lost here. I just got my new Mac Pro in the mail today, got everything setup with my 8GB of RAM and 2 video cards. I have the stock one and a 3870. I want to use 2 so have 2 monitors and my 61" TV plugged into it.

Everything is working, except which my primary desktop shows up on. My desktop is showing up as the TV which as you can imagine doesn't totally work for what I am trying to do. How do I set which screen I want to be my primary desktop ?

Thanks much :D
 
Open System Preferences. Go to the Display Preferences. Drag the little menu bar from the screen it's on to the screen you want it on. That'll be the primary screen.
 
DOH! I just figured it out ... I guess it helps to read the instructions on the screen.

Please ignore this ... but if you are also having this problem ... the answer is move the white little bar between the screens :D
