There are many ways to rotate the screen. SO, here are the two most effective ways you can do so.

Method 1: Via Keyboard

If you have windows 7 or 8 then you can simply rotate your screen by 90°,180° or 270° at anytime by just pressing three keys simultaneously.

Ctrl+Alt+ the arrow key where you want new dirrection of scree.

For example i want to rotate my screen 90° clockwise, then i would press

ctrl+Alt+ right arrow key

Similarly if you want 180° rotation, press the arrow key twice.

Method 2: Via Control Panel

Step one

Another way to rotate your screen is to right click the Windows desktop and select Screen Resolution from the dropdown menu that appears. Changing the screen orientation via Control Panel is equally simple. Press the Windows key and type in “Screen Resolution” then press enter.

Alternatively, if you’re using Windows 7, you can click Start > Control Panel > Display > Screen Resolution.

Step two

From here select the monitor that you wish to rotate from the Display drop-down box and then finally select Portrait or Landscape in the Orientation field.

Hope you got it.

Thanks!
