I have found one out of six WinXP PCs in which CTRL ALT Arrow will turn the screen display by 90 or 180 degrees. Where would this functionality originate - in the Monitor, the BIOS, software or what ? Basty

Graphic cards especially on certain ATI & Nvidia. FYI: CTRL+ALT+arrows do not work on every computers. If you don't have the above graphic card you don't have this feature.

Psss... Got too much time to kill? Try...
Ctrl+Alt+Up - right side up
Ctrl+Alt+Right - 90 degrees
Ctrl+Alt+Down - 180 degrees
Ctrl+Alt+Left - 270 degrees
If that doesn’t work try Ctrl+Shift+R.i_Xp/VistaUser
we use dell pcs where I work and on those I can not rotate the picture using those keys, but I know we could on some older Dells we had before they were replaced with newer ones. It was a good trick to do this whilst someone was at lunch and left their PC on.
I saw someone work all afternoon with their monitor upside down as they could not find any other way of getting the image up the right way.
