Sometimes your cat decides to walk on your keyboard. Sometimes you just type the wrong key combination. And sometimes, all you have to do is bump or move your laptop in the wrong direction, and BAM!
Suddenly, the image on your screen is rotated to the left, rotated to the right, or even upside down.
The first time this happened to me, I darn near had a fit.
Not to worry though: It’s not Russian hackers doing it, and it’s rather easy to fix!
