how do I rotate screen display 90 degrees - I'm reading sideways

Somehow my Dell Inspiron laptop screen rotated right 90 degrees so I am reading sideways with my head tilted to the right.  How can I fix it by rotating the display 90 degrees left?

Right-click on the Desktop, choose Screen Resolution then change Orientation to Landscape and Apply the setting.

If that doesn't work try to right click your desktop and select graphics properties, it will open your graphics chip and look for (rotate) and click it and some choices should be listed.

You can also right click and select (graphics options), point to (rotation) and check (normal) if it's not already or adjust it to the right spin direction :)

Hold down the Ctrl+Alt keys and use the arrow keys to rotate it back.
