A client accidentally pressed some keyboard key combination by setting something heavy on the keyboard… and her desktop flipped on its side. The screen orientation is fine when rebooting up until after the Windows Welcome screen. When the desktop appears, it is flipped 90 degrees. I tried Ctrl-Alt + the arrow keys. Didn’t change anything. I also tried uplugging the PC & Monitor – waiting a few minutes, plugging back in and rebooting. Didn’t help.
Windows XP w/ SP2
ATI Radeon 7000 video card
Viewsonic Monitor… ( Monitor control located on the monitor does not have rotation button.)
