Windows 7: GeForce GT520 combines monitors

GeForce GT520 combines monitors

I bought a GeForce GT520 in order to run 4 monitors, which it claims to support. The card has 2 DM559 connector sockets and comes with 2 special splitter cables for them, each ending in 2 standard DVI connector.

Until now I've run with 2 monitors, and today finally plugged in a 3d. When I boot up, instead of showing 3 monitors, the video controls show 2 monitors, one of which is double-width. The 2 monitors on the same splitter cable show as one. That is, when I plug in the 3d on a different cable, the monitor it "merges with" changes.

That might be acceptable except that what shows as a double-wide monitor has an unrecognized brand and is set at minimum resolution, so for example my 1920-wide pixel monitor plus my 1620-wide pixel monitor together show as 2560-wide (2x1280), losing almost half of my pixels.

I clicked everything I could find on video controls and NVidia controls, including "force detection" of monitors. What can I do to get it to recognize the monitors separately? I'm quite sure Windows 7 itself can recognize more than 2 monitors. Even 3 or 4 years ago I was running 3 monitors on my XP machine and I remember seeing the 3 separately in the Screen Resolution window.
