Determine the number of monitors, their resolutions, and their positions relative to the main monitor. Then, move the origin of the d3d app window to the left-most possible position (if your secondary monitor is to the left of your main one, your origin will have a negative X value). You will also have to make the window large enough to wrap over to the other monitor.

I'm generalizing because I'm not familiar with d3d, but I know you can do that with regular desktop windows.

Oh yeah, you're going to have to make sure your video card isn't configured to mirror the desktop on each monitor.
