Eh, the only "ugh" thing about that new Alienware monitor, to me, is the low resolution - 1440p at 27"/34"? No thank you, 2160p or better + fractional scaling just looks so much better for those of us editing text and/or code all day.
It’s worth mentioning that display scaling was one of many dealbreakers that made desktop Linux unusable for me: https://news.ycombinator.com/item?id=28490753
I’m pessimistic about any of this getting fixed in the next few years.
That Alienware monitor is clearly targeted for gaming. Regular 4k is already difficult enough to achieve in AAA games, expanding that to an ultrawide aspect ratio would only make getting acceptable performance harder.
