The problem is half of the popup is on the one screen and second half is on another screen. it's unreadable. how to make the pop-up stay on one screen?

Answer 1

The pin is your friend!

Press that pin in the top right corner to "Open as tool window"!

From that moment on, the documentation will always appear in that specific window. Just resize it and place it somewhere in your screen where it does not interfere with other things. From that moment on, every time you press Ctrl + Q the documentation will appear in that window.

But it may be more handy to drag the popup with the mouse:
