How to turn on display with mouse move but not with VK_SPACE

Question

This code disables 1 display out of 2. The task is to turn it on not from VK_SPACE, but from mouse movement.

I tried to do it through WM_MOUSEMOVE, but so far nothing has worked. I don't really understand how this problem can be implemented.

If there is an opportunity to implement this topic, I will be very grateful.
