Hello, daegeunhong. Thank you very much for contacting the Intel Communities Team. I will be more than happy to assist you.
I would like to start by mentioning that in newer drivers versions of the Intel® HD Graphics, the shortcuts to rotate the screen were removed. On the other hand, you can manage this through Windows* by right-clicking on your desktop > Display settings > Orientation drop-down.
I knew how to rotate the screen by mouse clicking. Just wanted to be able to do it easily by keyboard shortcut as its former version had enabled it. Wish the newer version of the Intel graphics had the better usability or at least maintain the same functions.
Anyways, thank you for your comment.
