I find this so strange. Pixel density being high is far less of an issue than it being too low, the biggest thing is you get less of a benefit from it when you have a smaller screen. This is especially true for productivity applications, though I would say that for gaming (or media) it's a different story since you don't always want to push high resolutions at smaller scales, since the density benefits you less and the performance impact is more pronounced.
I completely disagree here. You have some noticeable tradeoffs using DLSS or FSR in regards to image quality, so anything that appears to be native will always look better. In the past dropping resolution below native for performance reasons looked terrible, because LCDs simply don't look good below their native output. This alleviates that somewhat, and also gives you the option of going for full performance if needed. This is attractive to someone like me for a myriad reasons: I like higher density for work-related reasons, I like high refresh for casual or single-player games, and I like extra-high refresh for when I want to play a competitive shooter. I do all of these things, so having a jack of all trades is really a win. That said, I really wish it wasn't an edge-lit design, so I'm sticking with my 27" 1440 mini-LED for now, but in the future this is the kind of product I'll replace that with.
