You may have to get into a Fortnite forum.
So recently i changed the hertz on my monitor from 59 to 144 causing all of my games to run far better except for Fortnite. As seen in the photo in the url the game becomes distorted causing a green and redish tint over the screen as if it was an old vhs tape. The issue goes away when I change the games settings to windowed/ windowed full screen however, when the setting is set to full screen this happens. Any ideas as to what can solve this?
