With 4K you can lose a lot of performance especially since they are often paired with integrated graphics. Also what's the point of a higher pixel density when it's higher than you can resolve? Meaning if you have to zoom that's a sign that you get nothing more from increasing resolution. Also despite claims to the contrary, a lot of software is still not well suited for 4k resolutions.

High refresh rates are completely underrated as it's at the same time a meme but also a widespread false belief that human eyes have some kind of limit that is being satiated by your 60hz displays. Scrolling code on 144hz is smooth.

Bonus point that isn't mentioned in the article: HDR is a meme, don't buy into that crap.

Also: CRTs are criminally underrated and still unfairly judged. We lost something from that era. Colors, black levels, subjective image quality and input lag have still not recovered from the peak of display technology in the year 2000 or so.
