Upside-Down-computer-screen

  Some of my friends reported that their computer screen became upside down.

The kids made it.  Usually kids play a lot with keyboards while playing games on it.

To fix flipped screen of computer, you just need to press Ctrl + Alt+ Arrow key.

Using Ctrl+Alt+ any arrows keys you can rotate the screen of computer. It's not a bug or virus.

It happens with Dell LCD and other monitors. This allows your customer to view the screen from their angle of view.

to rotate monitor screen.

You can simply reposition the screen by pressing ALT+Ctrl+Arrow keys simultaneousely.
