Hello,
Wife is out of town and I noticed the monitor in her office is bigger than mine so I swiped it. My monitor is a 24" 1080p @ 60hz variety while hers is a 27" or so, 1440p @ 180hz. What a difference in AH3! It was like having cataracts removed and a fresh new prescription set of glasses installed on my face. Everything is shockingly clear and nice and any and all pixelation seems to be gone. Also, I may be wrong but my TrackIR seems much smoother too. I didn't want to tax my Nvidea 3080? vid card too much so I'm running at only 165hz but I don't think it'll struggle at 180hz as I didn't note any raise in temps or tearing while the frame rate was never below 165.
I must say I heartily recommend such an upgrade and I have begun the search for a 1440p monitor even bigger and better than this one just to one-up my wife.
