Welcome to the fantastic world of nearly no game supporting your resolution aspect ratio ;P
To be fair, I was surprised how many games handled the resolution gracefully. I've only encountered maybe 1 or 2 games (ironically enough, both AAA games) that had black bars on the sides, and one game that did some horrible scaling of the graphics.
So while I understand I'm absolutely a tiny minority, I'm still pleased with how well it works. And shout outs to Hollow Knight. That game really handled the monitor resolution beautifully with a combination of scaling and increasing the viewport.
And yeah, the curvature is natural. I don't even think about it. That said, I guess it's a touch overkill for an IPS panel, as they have *great* viewing angles. Though I can imagine it looking a bit off if it wasn't curved...I dunno.
But yeah, movies and youtube is where the monitor suffers the most (black bars everywhere), but considering I mostly just shove youtube or a movie on one side of the monitor and do actual work on the other, it doesn't bother me.
It's really a joy having almost another million pixels to work with without that stupid gap in the middle (compared to my previous set up with two 1920x1080 monitors).
