So i actually figured it out somehow. The option to go 4:3 is never there on the main monitor, until you switch from DVI display to HDMI. When you’re there and the game feed is strethced to 16:9 by default, the option to go 4:3 THEN unlocks. You may also have to be a in a specific color mode, but i was just on Standard mode and it worked fine. Can’t speak for any later models, but i just thought i’d update you guys on how i fixed it.
