Android Emulator Screen Size not the same as device frame

Question

When I run the emulator the screen size is smaller than the device frame as in the image below. It only happens in a computer with a screen resolution of 3840 x 2160

Answer 1

If the above Emulated performance is grayed out , which it was for me so the above answer did not help.

Not the most efficient way but you can change your screen resolution down to (1920x1080) and scale factor to 100% and it runs fine. You may have to restart your computer.
