Rotate external display

Open it up and you will see three different angles listed there; 90, 180 and 270. Selecting the 90 degree option will rotate it to the left, 180 degree will rotate it, and 270 will rotate it to the right.

Rotate internal display – Macbook
If you have a Macbook and use the same trick to try rotating the screen, you will see that the Play option simply does not appear. This might make it appear that the Macbook's internal display cannot be rotated, but that is not the case.
If you have the System Preferences application open, close it. After closing, hold down Option + Command on your keyboard. Left-click the System Preferences application in the Dock to open it. Do not release Option + Command.
Once the System Preferences app opens and you still hold down Option + Command, click Display Preferences. This time, the preference for the internal screen on your Macbook will show the rotation dropdown menu that it shows for the external screen . The same rules apply; You can rotate the screen 90, 180 and 270 degrees. 90 will rotate it to the left, 180 will reverse it and 270 will rotate it to the right.
Like an external display, you must confirm that you want to keep the new orientation within the specified time limit. If you do not confirm it, the screen orientation will return to normal.
If you're wondering why the rotate screen option is hidden on a Macbook, it probably has something to do with Apple trying to prevent users from accidentally changing it. There was a time when you could really change the orientation of a screen Windows PC with keyboard shortcuts and causes a lot of problems Windows users who accidentally run shortcuts.
