I couldn’t find any posts, but I’m sure I’m not alone in this.
Whenever I take photos, I go to 4K instead of 1440p for that extra detail, but recently it’s been going completely distorted and green. A lot of games have done this over the years, and usually you just alt+enter a few times to get it to figure itself out. Horizon 4 wouldn’t have it.
Basically all I did was roll back my nVidia drivers from Oct10 to the previous one (sept 24/25 or something) and it’s fixed.
So if you’re running a 4K screen/tv and when you full screen and it goes ultra wide skewed, and all green, try rolling back your driver first.
