Alt + right arrow - Microsoft Windows XP Professional

On Windows 7, it says graphics options instead of monitor settings.

Typically, to fix this type of error, you would use ctrl+alt+up arrow key to flip the screen right side up.
(incidentally...
ctrl+alt+right arrow = flip to the right
ctrl+alt+left arrow = flip to the left
ctrl+alt+down arrow = flip upside down)

If that doesn't work, or if your keyboard shortcuts have been disabled, right click on the desktop background, click on Graphics Options, then Rotation, then Rotate to Normal.

Also, if you have Intel Graphics installed on you computer, the software might have reset the default rotation setting. To fix this, right click on the desktop, then click on Graphics Properties. This should bring up the Intel Graphics window. Choose Advanced Mode, and click OK. Find the rotation settings (right side, 2nd from bottom), and choose Rotate to Normal.

Depending on your driver, it can be ALT + left arrow (or right arrow), or CTL + left arrow (or right arrow), or MAJ + left arrow (or right arrow), or any combination of ALT, MAJ, CTL plus one of the direction arrow...
