This is my oldest machine still in service, and it is 32bit XP.  Removing the SLI bridge worked, but I can't rotate the desktop on the second display.  I need it in "portrait" mode, rather than the default "landscape" mode.  The primary monitor is 2560x1600, so I have this second monitor rotated to "Portrait" so that it is 1200x1600 - with the pixel height matched, so that there is no "deadspace" on the desktop.

  When I used this monitor as a secondary -also paired with a 2560x1600 primary- on Galadriel (64bit Vista), the control panel / display options included rotating the display on the secondary to "portrait".  I don't see any means of doing this on TinkerBell (32bit XP).

I used another DVI for the secondary, pakled;  1600x1200 (or 1200x1600, since I have it rotated to portrait mode) is the highest res I've seen for 4:3 aspect ratio monitors, so I don't know if VGA could tote the load.

If anyone knows the trick to rotating the desktop display on ye olde XP, please do tell!
