I use a dual head PCI Card for two monitors and an S3/G onboard video card for 3rd monitor. The onboard card is not seen by FS2004, as in not appearing in display/settings dropdown menu.To use the 3rd monitor I have to go in windowed mode, with the associated loss of framerate.Any fixes?

My setup has some similarities. I run only in window mode- full screen just doesn't work- jittery mouse/image control probs. I have no problem with FPS in window mode. Very smooth-NO stutters.System is: AMD 1.8 GHz, 1.28 GB Ram, Dual Head GeforceFx5200 and a same type PCI card. I run triple views- LFwd,Fwd,RFwd, 2D main panel plus all popups open- even both L&R CDUs with PMDG 747! DO NOT allow any view to overlap an adjacent monitor.The views are adjusted in Panel Config for the precise width of monitor bezels- which also keeps them fully aligned in roll and pitch.I also mix LCD & CRT- no problem after a bit of colour balancing.Incidentally, I had an S3 card prior to switching to the PCI GeForce card- didn't work with the AGP GeForce dualie.You didn't say what your view arrangement is. I can only comment that once you've flown with a 180

I actually figured it out. it was as simple as the 'invisible' card having the 'hardware acceleration' slider in control panel set to none.It works full screen now.

Glad to hear it's working. Do you use mutiple views:Fwd +LFwd or RFwd?I got horrible stutters when I first tried this. Solution was simple-Retard Hardware Accel slider(s) on secondary monitor(s) 2 notches.I'm now running triple views/triple monitors, in a fully synchronized horizon 48" wide,covering 180

I have a 19" for displaying scenery and a 12" for displaying instruments.The 3rd monitor is a monochrome 9" which I will used with either a GPS for cruise flight or a L/H forward view for landings. Frame rate seems OK in this config, but detail is set to pretty low in FS2004.
