I have four 2560 x 1600 monitors. My goal is to have one huge display that windows thinks is just one monitor, at a resolution of 6400 x 2560.

I've found video cards that support rotating the monitors, so currently I have each monitor rotated, and I have an effective display size of 6400 x 2560. However, windows thinks it is 4 separate monitors, and for my purposes I'd like windows to just see one huge monitor. I've found a video card that could do this for two displays side-by-side, but not while they were rotated. Is there any way to get this to work?

If I remember correctly, Matrox manufactures graphics cards which should be able to do something like that. Take a look here: – AndrejaKo Aug 16 '10 at 13:33
@AndrejaKo: i've tried the Matrox triplehead2go and the NVidia NVS-450. both claimed they could do it (from what I understood from the specs) but both couldn't. – Claudiu Aug 16 '10 at 13:35
Well, now we at least know what doesn't work. Did you check out their real cards? Unfortunately, my information about Matrox is pretty old, so I don't know if they have such cards still available. – AndrejaKo Aug 16 '10 at 13:37

ATi Eyefinity can do 4x1 in landscape mode or 3x1 in portrait mode.
