Mac - black screen when mouse is on the corner

When the mouse reach the top left corner of the screen, all becomes black. When I move the mouse everything comes to normal, it is not a big issue but it is really annoying.

Any help?

iMac screen goes black randomly when mouse moved right. I have a 2019 iMac 27". Every now and again when I move the mouse the screen just goes black. Randomly but frequently, normally when I knock the mouse with my arm and it moves right, although attempts to simulate it have failed so the best i can say is "sometimes when I accidentally move the mouse the screen goes black", press "enter"on the keyboard and things come back. Interestingly, while the screen is blank, typing in the keyboard has no effect. It's exceedingly annoying when you're right in the middle of something important, like this post!! Does anyone have any idea? I have tried googling this but I just find lots of threads about mac screens going black and waking up with a wiggle of the mouse.

Disappearing Cursor Often on start up, my wireless cursor pointer does not appear. I have to restart my Mac Pro. Or I attach a mouse, which works, then disconnect wired mouse, and wireless mouse works.

You have setup "Hot Corners" to use "Put Display to Sleep." Go to System Preferences...>Mission Control>Hot Corners... and change your preference. How to use Hot Corners on Mac
