If only it had higher pixel density. If there was a 43" 6K or even 8K screen I'd buy it in a heartbeat. But with only 4K I have to use all sorts of weird tricks with raster fonts to make the text in my terminals sharp.
Also, too bad all the TV makers stopped making 8K screens in 55" and below.
I tend to agree but more because the market has settled on it. One thing about screen size is that it's easier to achieve an effective screen size with a smaller screen (by moving it slightly forward) than it is to do the reverse. So a 24" screen will work in more environments, e.g., smaller desks, than a 27" will. A dual screen setup with two 24's will require less neck movement.
Of course, the market has also decided that decent aspect ratios aren't worth doing either. If there were 3:2, 4:3, or 5:4 options—more versatile for productivity—we'd probably settle on something between 21" and 24".
It really is, 4K 27" monitors that can do >=120Hz are perfect for me personally.
I just wish that the base macbook pro models supported 3 external screens without resorting to a software-based video-over-usb DisplaySync (not DisplayPort) connection.
So far the screens I've tested are more tiring to my eyes (I work both on a M1 13" with external screens, and on a legacy 27" iMac). What are the best 27" screens for coding comfort that work well with Macs these days?
Apart from the Samsung Viewfinity that another commenter mentioned, there's also the LG Ultrafine 5K and the Huawei Mateview. The MateView is nicer than other 4K monitors because it has a taller aspect ratio of 3840 x 2560 so the extra 400 pixels of vertical space is nice for productivity work, although of course this is still fewer total pixels than a 5K display.
I bought mine like 2 years ago and it's been rock solid. IIRC they had some revisions over the years. And being rock solid: that's a bit of a lie because the monitor is wobbly as hell. So I've propped it with two supports on each side. Apart from that, the picture is the nicest I ever had from a monitor, and I had a lot of good ones. Text is super sharp and has acres of pixels. Compared to 4K monitor I can have both a terminal client and a browser side by side all looking nice. Can't fit that on 4K unfortunately.
I haven’t tried it myself but if you really want that 5K 27 inch form factor samsung’s viewfinity s9 is exactly that. Or apple’s studio display ofcourse.
