Turn Your Desktop Upside-Down!

Today I faced someting that struck me odd. I turned on the monitor of one of the computers at my school and I was wide-eyed when I saw that everything was upside-down. After doing some quick reserch, I found out that many monitors are capable of doing this. Even my laptop monitor.

Some computers when you hold down CTRL, ALT, and an arrow key will automatically rotate the screen display 90 or even 180 degrees, depending on the arrow jey you press. Sometimes you'll have to go into Display from Control Panel, the go to the Settings tab, click "Advanced," and find within there the screen rotation settings. This may be handy for tablet PCs so you can experience different angles of the screen in certain situations. Other times it's a prank.
