With the two nVidia GeForce 8800GTX cards in SLI, I could not get a second monitor option at all.  I removed the SLI bridge and the second monitor option appeared.  Each video card now drives one dual-link DVI 2560x1600 pixel monitor.

     I don't know much about this, so I can only pass on what I experienced, for what it's worth.  Maybe one of the more knowledgeable folk can explain/correct my findings.

In Vista and Win7, you can rotate the display in the Windows control panel (display), but no such option exists in WinXP.  I didn't find a rotate option in the nVidia control panel (on the WinXP machine) either, but it is there now.  I don't know whether it appeared due to removing the SLI bridge, or if it is due to installing the new nView driver/utility package.

     But if you have WinXP and want to have a different desktop image on the second monitor, you'll need to get the free nView package for XP.  Then use any photo program to break a double-width image into left and right halves.   Set the left half as the priimary monitor background, and the right half as the secondary monitor background.

     I have gobs of manuals -I love actual paper book manuals and will pay extra to get them if needed- but they are on more of the black steel wire racks, behind the camera.
