Hey I'm debating between the

ROG Strix XG27UCG 4K IPS

VS

ROG STRIX XG27AQDMG 1440P OLED

I easily have headaches, I never had an oled tv or monitor to know. But my phone is OLED and I don't.

I don't know about fringing, but I like good text clarity, it's not only for gaming

Pixel density is very important to me, however contrast are also very important

I'm also wondering what is about curved monitors, I don't know if I shouldn't maybe just go to that route instead

Games I play: FPS almost only, Battlefield, Borderlands, CS ( not at a competitive level ) but I also want to try Cyberpunk, Hogwart Legacy
