How to you rotate the screen on your computer? i did it by accident but i dont know how?

This depends on your configuration setup. You might have a monitor which supports rotating, in which case you need to find a button or location in the menu where you can rotate the image. You might have rotation set in your graphics card setup, such as th ATI Catalyst Control center or NVidias equivalent setup program.

well to rotate the screen on your computer you right click and it gives you a list of options. choose rotate right or left and your problem should be solved.

click on the desktop, click graphics option,click rotate, click normal this will restore it

there should be sum buttons on the monitor where you can change the screen, how do u mean its rotated? is it upside down or something? if so ive no idea how u managed that

there should be some small buttons on the front of your computer. use them.
