One of my favorites is to rotate the screen either sideways or upside down.
Go to a blank spot on your desktop
Right click
Go to "Properties"
Click on "settings"
Click on "Advanced"
Go to "graphics driver"
Click on "graphics properties"
Click on "rotation"
Go from there.
Depending in your graphics card, some of those directions may be different. The further you go in through the options, the easier it will be to find it.
Enjoy!
