I have had the problem that my monitor flickers for several weeks when I start Minecraft. Sometimes it turns black.
If I then go out of full-screen mode / window mode with the Windows key, Minecraft is of course still open, I can also see it on my monitor, the screen does not flicker and it does not turn black, but of course can't do any in-game.
Can anyone help me?
Try assigning more RAM to Minecraft:
Now, as I said in the video, I assigned more RAM, but the screen still flickers, I have 15.9 GB of RAM and I set it to 7200.
The screen still flickers
By the way:
It's not permanent, but in part, sometimes it's normal, sometimes not.
But it still doesn't work
