This is what I ended up going with. The colours were definitely a bit disappointing at first but after tweaking the osd I got a nice enough picture. Good enough that it doesn’t bother me next to my other screen I can’t measure performance but the monitor feels fast and there is no smearing whatsoever. Viewing angles are sadly limited especially for an ips display, so much so that this screen prpbably would’ve actually benefitted from being curved.

Would I recommend it overall? Maybe. If you are dead set on an ultrawide at this resolution there weren’t any other ips screens available this cheap when I bought it ~2 years ago, not sure how it is today. The VA panels at a similar price will look nicer, if smearing doesn’t bother you. Having the screen fill up your field of view is great and the monitor looks perfectly fine for gaming. You definitely pay a large premium for the aspect ratio, there are much cheaper 16:9 screens that perform better then this one picture quality wise. 21:9 is nice when it works (~85% of games I play, some sweaty e-sports games don’t support it on purpose for example) but you are paying extra for black bars when it doesn’t.
