I also run a fourth monitor, but unfortunately not as part of a spanned cockpit. It's a fourth monitor that hosts charts and popup panels etc. (Also allows me to multi-task with other apps while flying). This requires a 2nd video card installed in your system. It does not have to be a powerful one ... keep your current card for this.

I am sooooo glad someone brought this up....I have to use my laptop to view charts, and would like to use my main system to do so. I run FSX Accel in fullscreen mode with a HD6870 2gb XFX card and 3 monitors: a 55" Vizio VF550M for the VC, and 2ea HP2311x's for instruments such as the FMC and PFD/HSI (and ATC). I exclusively fly the 737NGX with FS2Crew Voice and GSX, and I get 25-30 average FPS on the ground, 30-50 in cruise, and approx. 20-25 at KSFO. :-) Any ideas on what would be a good second card to match my system? Any other things I should know to go after this solution? Thanks! Sean

Hey guys- could really use some help here...do I pick a card that will run the same drivers as my HD6870? Or does it run totally separately and have it's own driver install? And how would I get FSX to utilize only the HD6870 ports? Any help would be greatly appreciated!

Wow...this must either a stupid question, or a barn-burner of one.
