I tried all of your suggested Windows settings as well as every one I could find. Nothing worked. So I contacted MSI. The tech suggested I check Tobii Aware. I found it in the Apps section of settings. It turns out that it is some kind of eye-tracking app for gamers. I found a screen setting and turned it off. That seems to have worked.
Two points:
- Tobii is a Microsoft product. As such, I would think that someone offering help on this Microsoft board would know about it.
- This MSI laptop is the worst piece of junk I have ever owned. I will be replacing it with a real laptop as soon as possible. Then I will give it to one of my worst enemies.
