@TP4, my kid is using an old 1920x1080 75hz IPS display. Works well enough, but the kiddo wants an high refresh monitor, which I understand, since he is generating many more frames in his favorite titles than the monitor can display. I very much like my ultrawide monitor and wanted to know your thoughts on 2560x1080p for esports and casual gaming. He has very little interest in single player/cinematic games. I know his 4060 would struggle at 1440p and high (120hz-144hz) refresh. I see that that the 1080 ultrawide has ~33 more pixels than regular 1080p, but 1440p has +78% more pixels, which is why 1440p is out of the question. If my son is shooting for 120hz+ when playing Fortnite and is willing to scale down the visuals to get that, is 2560 x 1080 a realistic resolution. He really enjoys the customization/flexibility that PC gaming offers that console can't.
My real concern is playing other games and how taxing those extra pixels would be. He really enjoyed my 1440p ultrawide, but even now I realize that 1440p ultrawide/High refresh will require a significant investment when my 3080 starts showing its age. My kid will be a teen shortly and be able to enter the workforce soon to afford his own gear so this is all solutions for now, knowing in 2-3 years parts will be replaced.
2560 x 1080 = 2.76 million pixels
1920 x 1080 = 2,073,600 pixels
2560 x 1440 = 3.7 million pixels
