Monitor recommendation - 4k, 5k and what size?

[maflynn]

Long story short, the way macos handles scaling/resolution, is such that my 1440p monitor is not working optimally for me under macos. While I would love to get a Studio Display, its hard to justify the price. There's also a level of ignorance, where if I can get more info on how/why macos handles scaling - that would be beneficial.


Current setup: An LG ultra-wide 1440p monitor, in windows I have it set at 1440x1440 with 125% scaling. Texts, UI objects are dead on sharp, no fuzziness. In macOS, the native resolution is too small to use effectually, my only option is to knock it down to 2560x1080 and things are just too fuzzy. Not liking the experience.

I was leaning towards a 27" 5k monitor, because there was some info about macos and 5k monitors is the pixel density is such that 1/2 of 5k is 1440p so macos scales 1440p with crisp/sharp texts and UI elements. Something about how 2 physical pixels make up 1 logical pixel and the higher density of 5k makes ensures excellent rendering at 1440p

If I choose a 4k, what size monitor would work best then 27? 32? If 5k is going to look great at 1440p, does that mean 4k has to be run at 1080p to look nice?

Any links to explain how macos handles scaling?

Finally, what 5k and 4k monitors would you recommend? The LG 5k is nearly the same price of Apple's studio display so I don't see any reason to choose that, other then I've been really happy with my current LG monitor. I see Asus Proart 5k monitor is an option that is under a 1,000 and its generally positively reviewed. For 4k, I'm unsure what size, though I'll probably be looking at LG

The Dell S2725QC has great specs for a $320 4K 27” monitor, others here have reviewed it. It might be worth researching it.. I have the previous model and am pleased, but really wanting to get this one for the HDMI 2.1 120hz capability..

Dell 27 Plus 4K USB-C Monitor - S2725QC | Dell USA

Shop the Dell 27 inch 4K USB-C Monitor with AMD FreeSync Premium, 120Hz refresh rate, dual 5W speakers, and 4-star eye comfort.

Good luck 👍🏻

There aren't any.
At least... at the moment.

Acer is supposedly releasing one later this year:

New Monitors In 2025: What To Expect [Professional, Gaming]

Find out what LG, Samsung, and AU Optronics panel manufacturers have in store for us in 2025. There are some exciting models coming up!

I'm watching and waiting with interest.
Perhaps there will be a few more to appear after this one, but that may take a while.

Option 1: download BetterDisplay. The free version should be enough for your needs. Turn on the button for HiDPI and use the slider to set your logical resolution to 2560x1080. This will give you the HiDPI assets scaled to your preferred resolution and maybe you will be happy.

Option 2: get a HiDPI display. If you have the eyes for it, you may like this better than what you are currently experiencing in Windows at 125%. Which one to get depends on your budget:

4K: LG 24" UltraFine 4k. Exactly that one. Is discontinued but can be found cheap on eBay etc.
5K: I recommend hold until Apple updates the Studio Display. If you want to buy now, either the Studio Display, Asus ProArt 5K to save some money, or Kuycon 5K if you are willing to gamble getting great value for money but uncertain direct-from-China support. Buy from ClickClack.io not Kuycon.us. Kuycon.us is not an authorized retailer.

I tried that already, but maybe I'll revisit that once more.

That one looks interesting, so you're saying is, this could be a good deal, but given its a chinese import, don't hold your breath on support.

I've been retrying BetterDisplay, and I think this may be a good temporary solution. 2560x1080 is not HiDPI for my monitor but there are other resolutions that are. I'm running a resolution that is, and its producing a better output, which is helping - no more eyestrain or headaches.

I'm still going to hit my local Microcenter tomorrow and see what options I have. Also, I've been using the free version of BetterDisplay, I'll pay for the pro version, partly for the other features unlocked but also to reward the developer for this application.

Thanks for the suggestion

It's not half the pixels, but a quarter of the pixels when you compare a 2560x1440 (2K - 2.5K) monitor to a 5120x2880 (true 5K) monitor on a 27" screen!

To answer your question briefly: You have to hit the right “grid” to really have a sharp display of text! The answer is: You can use any monitor that offers ~220PPI. The only thing that varies then is the available working area.

There are/were 24“ monitors with 218 PPI, a few more 27” monitors with 218 PPI, and now also 32" monitors with ~218 PPI. If you then select the scaling in macOS so that the font is not too tiny but is still displayed absolutely sharply (usually 1/4 of the physical screen resolution or 200% scaling in Windows), you have a perfect working environment!


Unfortunately, not all users understand this, because the point is that such monitors always cost a little more, and the average user tends to look at the price and then argue that, at a certain distance between the eye and the screen surface, the resolution of the screen is no longer that important. WRONG! Because with this argument, you could have stuck with Full HD, but reality shows that users definitely want to use resolutions higher than 1920x1080 and are very satisfied with them.

Some of us have already moved on with our own requirements and love working at 6144x3456 on a 32" screen, which is simply awesome (at 200% scaling), because then the screen looks as brilliant as on a smartphone, only you have much, much more space to work!

Here's one video that helps explain macos scaling. I knew there was something about 2 pixels to 1. He explains it better. In macOS the default image of a 4k display is 1080p, and for 5k its 1440p and that helps explain why my 1440p monitor does a poor job when scaling down to 1080p because its not
