How to fix the screen, if it was crossed at 90 degrees

I don't know if it happened to them, it's the first time I've seen it, but without knowing what I did, the screen crossed me at 90 degrees. Apparently not all computers have this property but on a lonely hotel night without Internet this is fatal.

I consulted with those next door watching the football game and gave me three solutions:

1. First: I called the support technician of the municipality, spent half an hour looking for ways and then closed the door and said:

Mlerda!

The next day it took me to format, I paid $ 45 for that.

2. The second He told me that he was like this, working for two days with a crooked head, everyone who asked him did not know how to do it, they just laughed. One even shook it saying that some tablets had that function of accommodating according to position. Someone finally fixed it but I never knew what they did.

3. The third He said that a technician fixed it one day, pressing some control buttons, I don't know what else. He called the girl but she did not answer the cell phone ...

Do not spend more time, this is done like this:

You press the key   ctrl + alt and the key on the direction arrow. If you press the one on the right it crosses at 90 degrees, the left at –90 and of course, the one on top places it in the normal position.

Jeje, I guess crossing the machine can be used to see photos of girls in full size.
