I have an ancient Dell P2415Q which is a 24" 4K. Love the pixel density, I care about that more than sheer size, it fits everything and I'm in design software all day.

Great monitor pairing for my MBP. All these years later I have no genuine desire to upgrade, waiting for a higher refresh rate model from Apple.
 
Of course text will simplistically be sharper on glossy. The issue is how much one is offended by glare. Those who are offended by glare [me] prefer the matte finishes. YMMV
Matte also reduces contrast - it's scattering incoming light from all angles into your eyes which a glossy screen would reflect away from your eyes. If a bright object is causing glare from a glossy screen then you'll be losing contrast on a matte screen. Some matte coatings also have an irritating grainy/sparkle effect - I see the reviews of the new Asus mark it down for that.

The optical coating (standard - I'm not talking about the nanotexture) on the 5k iMac cancels out a proportion of reflected light and does a good job of reducing glare while keeping the contrast and sharpness of a glossy screen. I assume that the Studio Display does likewise.

If you have the money then go 5K - you won't regret it. If you don't then just get a 4K and sleep sound - you're not missing all that much.

I get on fine with 4k - and the 3:2 4K+* displays I have are even better given the price - 2x4k displays for less than the price of a single Studio Display - although the matte coating is a downside & mucks up the contrast a bit. If I were buying today I'd investigate the

However, if I was prepared to spring for 5k, the alternatives are still quite pricey for what sounds like fairly cheap construction and iffy coatings, so I suspect I'd end up going for the Studio Display, despite my list of gripes (already covered in this thread I think) - because I'm confident that the actual display part is excellent.

* 3840x2560 @ 28" - imagine 27" 4k with over an inch of extra vertical space at the same ppi - which I'm running without fractional scaling at "looks like 1920x1280" - the extra vertical space (not to mention having two of them) helps offset the effect or the larger UI. The Huawei ones I have are discontinued (and would have been problematic for some anyway) but I see that there's now the Benq RD280U 28" 4:3 display (but I can't comment on what it's actually like)...
 
Iunno. I’m very happy with fractional scaling on a good quality 27” 4K from Dell. Matches nicely with fractional scaling (highest resolution) on my laptop; no evident artifacts; can’t see pixels unless I press my face up to the screen; can read text (aka code and docs) comfortably all day.

YMMV if you’re an artist, photographer, video editor, etc.

For larger screen dimensions, I would want higher resolution. At least 6K for 30”.
I agree. I have a Dell U28E510D (which is actually 28") that I got from Costco several years ago and I'm quite happy with how sharp everything looks at the 3008x1692 setting. I have my M1 mpb on a stand next to it and yes, that screen looks better - slightly sharper text and better color, but I never feel like it's a compromise when I look at the Dell.

Exactly!
 
4K is plenty and will likely be the last resolution I use. Anything more is currently prohibitively expensive for not much benefit. Obviously there is a difference in the visual quality but in the real world it’s so unimportant that the extra cost isn’t worth it to me. Anyone complaining about 4K not looking good enough needs to change what type of panel they opt for or simply stop being a fanny.
 
The debate over the discernible and significant value of 4k v. 5k is reminiscent of other analogous topics.

1.) The higher end automobile experience - a friend once gave me a ride in his Mercedes (I'm a Toyota Corolla man these days) and went on about how it had low road noise. This was even more pronounced later when he gave me a ride in his Tesla. Yes, yes, very nice...but not a big deal to me.

2.) Audiophiles and 'vinyl,' and higher end sound systems. I don't get it (and save a lot of money as a result).

3.) Foodies.

4.) Noise in digital photos. If it's not glaring, some don't readily pick up on it, and for others it may ruin the shot.

For whatever reason, some people have a greater than average ability to discern subtle (to others) differences and their experience is meaningfully impacted. The problem is, until you experience the subject yourself, it's hard to know where you fall in the spectrum of response.

And to be fair, there's an arbitrariness in drawing the line on what's 'good.' Right now, a 5K 60-Hz 27" display is excellent, right? Okay, let some vendors put out 5K 120-Hz 27" displays. How long till people are lauding them, and talking about what an inferior experience the 60-Hz is?

How much more are you willing to pay for lower road noise, very realistic sound, a steak Gordon Ramsey would love, a high ISO sensitivity camera or a 5K monitor?

A lot of people are happy driving Corollas or Civics, listening to non-vinyl music, fast food, iPhone camera work and 4K monitors.

What makes you happy?
 
I do notice the difference, but for most uses I can't say it's a life or death matter, especially as I pick non-integer scaling even for 5K monitors... If I'm paying for 5K I want moar pixels (e.g. I use a 14" 2880 x 1800 windows laptop at 100%).
 
I was speaking of physical desk space only.

Any on my 27" Dell U2723QE 4K, I switched from 1920x1080 to 2624x1476 via Betterdisplay, seems ok and closer to the Windows 10 scaling I had for the monitor. Will see if I can adjust to this.

then your reply is lost on me... desk space is no reason to chose a 27" 4k over a 27" 5k ... they are roughly the same size. and that is what I have been talking about 5k vs 4k
 
Of course text will simplistically be sharper on glossy. The issue is how much one is offended by glare. Those who are offended by glare [me] prefer the matte finishes. YMMV
I could just as well say "Of course matte screens will simplistically have less reflection, but only if you are not able to control your lighting. The issue is how much one is offended by blur."

A more sophisticated reader would understand that of course matte has less reflection, so that was implict, and thus not necesary for me to mention. What's not as well-known is that, as pixel density increases, matte has a stronger effect on text sharpness. That's why Dell, whose default is matte screens, offered their ~280 ppi 8k in glossy only.

That's very interesting. Other 5K 27" displays I've looked into and recall (e.g.: the Asus ProArt) were listed as matte. Do you know of any non-Apple 27" 5K glossy displays?

Because Apple doesn't properly support fractional scaling so you can get artifacts and issues since it's not an even integer scale. On a 4K monitor to get an even integer scale you have to use "looks like 1080p", which on a 27"+ monitor looks huge and bad. Some people also don't like that 27" 4K is only about 150 ppi and want 200+ like the Macbooks.

This blog goes a bit more in depth into why some people don't like the non-integer scale:

Personally it's not something I cared about or noticed but some people do.
Basically this! I am not a display snob, but can remember my 2k cheap display running sharper at native resolution with macs.

Current 4k only shines in 4k videos, asides for productivity 4k on 27” is too small so i end up running on 1440p which objectively worse than native 2k display because of that non integer scaling on macs.

1080P scaled 4k display is good and i run it sometimes. For real productivity it is however useless since one application ends up taking the whole screen and you can’t work on 2 windows with that big screen.

So 4K is best 1080p display if you needed one.
 
I think its a whole lot of over the top reactions about scaling issues. Windows is a much bigger mess with a lot of programs just flat out not supporting this and everything is insanely small or blurry as hell.

I do graphical design and video editing where it really matters how my monitors look and I cannot tell these "horrible" issues with the 4k scaling running in 1440p mode. I simply CANNOT run at 1080p mode as everything is WAY TOO BIG. It looks much worse to me. And coming from a native 1080p and native 1440p displays, this 4k looking like 1440p is a significant jump in visuals.
 
Or set it to "looks like 1920x1080" and get exactly the same 3840x2160 resolution, and no fractional scaling, but with usable-sized UI elements and readable system fonts. All of those online articles about how 4k is rubbish tend to conveniently forget that option.
See this is where this whole argument is just making a mountain out of a molehill. "looks like 1920x1080" is not a good option as it makes everything way too big in my view. And suggesting that over the 1440p option which....again making a mountain out of a molehill.....still looks incredibly amazing. And this is coming from someone that depends on high quality displays for their profession.

I am on th same page with you.
 
Because 4k is only really visible on 65 inch or large displays. Less than 65 inches it is a waste of money, memory and pixels.
Nope that is false. Native 1440p displays at 27" and a reasonable distance I can still see the individual pixels. Not so with my new 4k displays. Everything looks much crisper and nicer with the 4k display.
 
I use Dell U4025QW - 40" very slightly curved ultra-wide, with a resolution of 5120x2160.

Effectively, it's like a 4K monitor with some extra pixels off to each side to make it wider.

I run it in "looks like 3840x1620", and it's wonderful. I think the scaling issues of macOS have been over exagerrated.

Is my MBP display better? Sure, and the ASD probably looks slightly better too.

BUT... this monitor offers way more screen real estate, it's 120Hz (which is a HUGE difference in "feel"), AND I can connect lots of different things to it (it even has a built-in KVM switch to flip between two different computers and switch the keyboard/mouse between them).

I'd love an Apple display, and I'd be willing to pay for one (this is a $2000 monitor, BTW), but they just don't innovate in this space.

Oh yeah one of the deciding factors for getting a new display was not just about resolution increase but refresh rate. Not only for the visual improvements and how things feel, but it is also quite significant at addressing eye strain. A lot of people don't realize how much of a difference it can make, even if you cannot "feel" the difference, your eyes will be much more happy with it. I was suffering a lot with eye strain and my eye doctor was the one that suggested getting higher refresh rate.

I would love to get an Apple display, but not until they at least make it 120Hz.

When did you last use Windows? 2010?

Nothing is "insanely small" anymore with Windows scaling. Most apps work perfectly. Yes, you can dredge up stuff from like 2007 and they'll be blurry but I'll take blurry over not runnable like MacOS. Windows scaling works correctly at fractional resolutions too, so 27" 4K @ the recommended 150% or 175% looks sharp in 95% of things where as on Mac OS it's slightly blurry in everything in "looks like 1440p".
 
"looks like 1920x1080" is not a good option as it makes everything way too big in my view. And suggesting that over the 1440p option which....again making a mountain out of a molehill.....still looks incredibly amazing.
I wasn't suggesting one over the other - they're both perfectly good options. Whether "looks like 1920x1080" is too big is a matter of taste, but it is very usable and eliminates any fractional scaling, if you have an issue with that, while using the full 4k resolution of your screen to display content. Ruling it out as an option is just as much mountain-out-of-a-molehill as ruling out "looks like 1440p" because you think it looks "a bit fuzzy". Same for "looks like 3840x2160" which IMO is on the verge of usability for people with with normal eyesight at 27" - I used to have a 4k 16:9 28" display and, back when my eyeballs were 10 years younger, could use it perfectly well.

If you're running in "looks like 1440p" mode and do hit something that is mussed up by fractional scaling and really, really must be displayed as "actual pixels" then it takes a few seconds to flip to "looks like 1920x1080" or "3840x2160". It also depends on what apps you use - I find that things like Affinity and VS Code - with the internal zoom and font size set appropriately - look perfectly sensible full-screened in "ll 1080" and give you masses of screen space.

Uh using it now actually. MSI Afterburner is something I use daily that does not scale. So do some legacy applications and open source software. Its horribly difficult to use these applications since everything is so small.

Using Windows and a 4K monitor set to 2560x1440, the image won't be as sharp as on macOS. This is because macOS uses oversampling, scaling to 5K and then downscaling to 1440p, which doesn't happen on Windows.
Moreover, on macOS, there will be no issues with sharpness or scaling in applications.
Graphics management on macOS is simply better than on Windows. If you want to use the same scaling system as Windows on Mac OS, you can do so: just select all the resolutions from the control panel, or use some app as monitor control or better display.

That is the difficulty with this argument. My original comment wasn't really directed at at you, I was just piggy backing off your comment as a spring board sorry for not making that clear. I constantly see in these topics over the years they either recommend 1920x1080 which is too big for a lot of people, or 3840x2160 is too small for a lot of people. And the only viable option to a lot of people (myself included) 2560x1440 is DESPISED in these threads causing a lot of confusion. Its all about the "fractional scaling issue". People either suggest one extreme or another and not the one that is ideally preferred by a lot of people and really......doesn't have the issues that are constantly brought up in these threads.

All in all, just go with whatever you like. The constant over the top reactions like 4K is HORRIBLE in macOS or macOS has HORRIBLE scaling is way overblown. Whether you want to use the 1080p, 1440p or 2160p looks like options they all have differently ideas.

I have seen variations on this topic ever since the first 5k iMac came out and it is exhausting. Just use it however you want. 4k is in no way horrible on macOS even if you use the *gasp* 1440p mode. It still looks orders of magnitude better than native 1440p. And if you are like me where 1080p looks too big and 2160 looks too small, than 1440p is just fine.

That depends entirely on viewing distance.
For a large screen TV that you're going to relax and watch from at least 10' away I'd entirely agree that 4k is pointless on anything smaller that 50". I think people are less sensitive to fine detail in moving pictures and photographic images, anyway.

For a desktop computer monitor where you're reading text and intensely studying detail we're talking about the "retina rule" - based on the definition of 20:20 vision - that people with "typical" vision struggle to see details less than 1 arc minute across (an angular measure - basically pixel size/distance plus a bunch of unit conversions). That works out to a viewing distance of 21" for a 4k, 27", 163ppi display - which is in the right ballpark for a desktop display at arm's length (and this is really only "ballpark" - 20:20 is only typical unimpaired vision - not even average - plenty of people have better or worse vision).

There's a "retina calculator" here: https://tools.rodrigopolo.com/display_calc/

...but you wouldn't do that on Windows. You'd set the resolution to 3840x2160 and the scaling to 120, 150 or 175% to adjust the UI size to taste. MacOS doesn't support the variable scaling option: you've got 100% (1:1) and 200% (2:1) baked in to (for a 4k display) "looks like 3840x2160" and "looks like 1920x1080" respectively, and anything you want in between is provided by rendering at to some other resolution internally and downsampling the result to 4k.

Windows has worked that way since the early days (you used to choose PPI rather than % but it works the same way) whereas Macs - possibly thanks to their DTP heritage - have always worked on a fixed notional PPI (1 pixel = 1 point in the early days).

I think the Windows method is better in theory, but it is very much dependent on applications implementing it properly, and you might still get fractional scaling on the application level: for starters developers can't include bitmap assets for every possible scale - and for 'vector' rendering might choose to render into a fixed-resolution buffer and then scale that to the screen. Mac applications just have to cater for 1:1 and 2:1 modes, two sizes of bitmap/icon, will "fail safe" if they only support 1:1.

It's worth noting that MacOS fractional scaling is very similar to "full screen anti-aliasing" that is used to make games look *better*.
