Games have color errors, what to do?

And indeed have me with games like Fortnite a color error. Restart and reinstall bring nothing. What can I do?

You have the 3D mode active… Red goggles on and off you go.

Possibly. But before that set the parallax correctly, otherwise all the time playing with the "view of the drunkard" (sounds maybe like an "RPG skill" it is only maybe). ^^

This is a 3D mode. You probably have activated this in the NVIDIA driver, or enabled ingame.

Where can I deactivate this?

Where you activated it. If you do not know, you have to search or google where nvidia has hidden it.

Okay, thank you very much!

Okay, it was a 3D error.

Once CTRL and T and already the problem was solved.
