Screen Display is side ways

You should always include the model of PC and version of Windows in your posts.

You can try pressing ctrl-alt-(up arrow key). If that doesn't work and this is a recent problem, you can try doing a System Restore using the most recent Restore date available when you know it was ok.

Depending on what version of Windows you're using---you can go to Start--->Control Panel---->Display----->Settings tab---->Advanced button----->Rotation tab (if you have one)

shortcut is to press  CTRL+ALT  and direction key any direction you wanted it to be :smileyhappy:

Thank you- Ctrl-Alt Arrow keys did the trick

Perhaps you've purchased a wall mounted monitor. :)
