I have been through a lot of different monitors until I was able to figure out what worked for me. With aging eyes and some issues with light sensitivity I was having a really difficult time trying to find the right monitors to choose.
I started out with 4K monitors from 27" and bigger - thinking that the bigger display sizes would be better. Since I run dual displays - the bigger I went the more I was being blasted with light and the worse the text crispness became.
I had just about given up when I decided to try a LG 24" 4K display. Once I played with it, I immediately passed my other LG 27" on to my daughter and picked up a second LG 24". I have them mounted on dual monitor arms and set to default scaling (looks like 1920 x 1080), which gives me total screen real estate between the two monitors of 3840 x 1080. Since the scaling is exactly 2 to 1, the picture is crisp and clear coming in at around 185 pixels per inch.
Until I realized that going with default scaling really does look the best, I kept trying to go with larger 4k monitors. Default scaling on a 27" 4k display just looks too big.
For me, the best screen size for a 4K displays is somewhere between 21" and 24". Since my eyes get tired looking at smaller text for extended lengths of time, the 24" works well for me, even if it does lower the resolution to 185 ppi. Text size is right around 92 pixels per inch, which I can look at all day long.
For screen sizes 27" and larger, I really do think that 5K displays are really the right way to go, which will give you an effective resolution of 2560 x 1440 with default scaling. A 5K 32" display, with default scaling, will give the same text size as a 24" 4K display.
Unfortunately, 24" and smaller 4K displays are tough to find and there are not many choices. The LG model I decided to go with was the LG 24UD58, which can be found from $250 to $300. For two displays and a dual arm VESA monitor arm mount, total cost is less than $700. If you read the reviews, there are many happy Mac users.
Seeing is believing with the LG 24UD58 4k UHD monitor. Whether your playing games, watching movies, or just reading from your screen, the 4k UHD display provides stunning images at four times the resolution of standard full HD. The 24UD58 works hard, but plays hard too. With a host of gamer frien...
