There are good “glossy” AR coatings that are not matte and like another poster mentioned are used on high end Samsung TVs, that let you have your cake and eat it too. Never seen it used on a monitor though..
Dell has several warranty levels from depot service to advanced exchange. Not sure what their monitors come with by default now but it’s worth reading the fine print. The “good” warranties are very good.
Interestingly, when Samsung flew out Linus from LTT to show them QD OLED I’m pretty sire I heard him say the monitor they used to show off QD OLED was the Alienware. Hopefully that means it’s pretty solid for a press outing.
Didn’t Linus stack two super curved monitors one above the other? IMHO you end up with something a lot like a single 49” normal aspect ratio monitor in that case just a little taller/ higher res.
I think for dual monitor ultra wide monitors make little sense (not that you can’t do it) but...
