Tip for those with single monitors...picked up from DCS Forums (thanks sebro83)
I can verify that for perhaps owners of some cards (NVidia) this is a valid way to go about extended your desktop even if you don't have a second physical monitor. I spent an hour the other night and finally figured out the proper settings.
I simply forced an 800 x 600 display via my display setup even though there really wasn't one there. Then I extended my desktop to that non-existent display. Opened up A-10 VC Server and slid the 300 x 300 displays over off the right side of my screen. It took some manual adjusting to get them in the right spots (since I couldn't actually see them).. But in the end, I have no MFCDs on my main game screen (1680 x 1050) and two perfectly exported MFCDs on my iPad!
Help that helps some people..
I'm using a GTX 285 w/ 301.42 drivers..
