My only gripe is nearly all common "ultrawide" models should really be thought of as "ultrashort" in that they don't offer more width, just less height. E.g. a 21:9 ultrawide variant of 4k should really be 5040x2160. Instead they are nearly all 3840x1600. That may well be cost/price optimal for certain folks, I'm not saying it's bad for the product itself to exist, but nobody was looking at a 1600p monitor thinking "man, I wish they'd make a wider variant!" they started with 4k and decided it would be nice if it were permanently shortened.
