Display Resolution and DPI

lcds dont work great in not native resolution, even if its perfect 2x scaling it still little bit bury, so if you did that (set the displa to 1080) on the same display im not sure that's fair, at least that's what i noticed in my experimentation, and i had/have a dell, apple , huawei and asus laptops with hdpi. for me the difference between high enough and 4k on a small laptop display is not that noticeable/important and it comes with drawbacks (at least on linux for now)

Why a 4k display on a screen that small? That is well beyond the limits of human visual acuity.

I don't think they would for me.My Dell u2412m has a pixel density of 94 PPI (I think?) which is quite low for today's standards but it does the job and I can't justify upgrading it. Compare this to my current smartphone (xperia z3 compact) which at 720p has 319 PPI and is still considered low end in this regard.Work provided me with a macbook pro retina and I don't see what's the fuss about. Hence running mostly on clam-shell mode.On older notebooks I simply us

I too don't have too good vision, but the 1080p 15" and the 2160p 39.5" at slighly higher distance are just at the point where I don't need High-DPI technology. Seeing pixels at 24" is not that hard. There are screens with significantly higher linear resolution.

I'd encourage you to plug in the screen size and resolution into a calculator like https://stari.co/tv-monitor-viewing-distance-calculator before making a decision that it's required. A 4k display is 'retina' at distances much closer than people sit, even at 27". On a laptop size screen, it's even worse.I have a xps 13 and I specifically chose the

I have a 14" 1080p screen. I put everything to 125% (like font sizes, etc.) It's okay. My eyes are very good at short distances so I don't mind things being small. But yes, Windows 7 does not have enough scaling options to make higher resolutions on smaller screens work. With Windows 10 it is no problem though. With Ubuntu it also shouldn't be a problem. Yes, you do increase rendering quality, but not by much. You can still see individual pixels. But any higher pixel density

I don't think so. From where I'm sitting, I can see the rainbow effects of antialiasing on my 4k 32" monitor. The easiest way to observe this is some skinny light text on a dark background.Other than that, I'm quite happy with my screen real-estate. So, I would indeed love it to have a higher resolution. I could probably use a somewhat bigger screen, a bit further away, that would do a better job as a TV the rare times I use it as such (don't have an actual TV). But a

No joke. I have very good eyesight and bought a 4K 32" display to run at @1x. When I started using the display, I had no issue with the pixel pitch, but the extra cognitive load of being able to see so much at once was such a downside that I've went back to my 27" 1440p display and I'm much happier.

At least 4k, getting old for staring at low-dpi screens all day.

I had 4k screens on < 14" laptops and I prefer 1080p. Pixel density is enough for my eyes, no scaling issues and battery runs longer.
