I have a mid 2015 15 inch Macbook Pro

Still need it to run legacy 32-bit software so it's running Mojave. I have a new MB Pro 14 inch M1 Pro coming in for all my other work, which will be running Ventura.
This will be replacing my 2017 27 inch iMac.

I'd like to get an external display for use with both laptops, and have some kind of KVM setup so I can use the same keyboard & mouse (and display, obviously) for both Macs.

Choosing a display, however, is proving to be more difficult than I thought it would be. The obvious choice would be a 27-inch 4K display, but I'm also looking at 1440p and/or maybe 24 inch monitors.
I've already looked into and read numerous posts about (on this and other forums) about the scaling Mac OS does with 'non native' resolutions ; most common use of a 4K display would be to have Mac OS scale it down to 1440p on a 27 inch display.
This comes with a performance hit, apparently, not so much of a problem on the new Apple silicon Macs, but still, a performance hit. Some say it slows down your Mac (so putting pressure on the CPU and/or GPU), others say it's just down to RAM.
To be honest, I'd like to avoid any kind of performance hit, big or small, and with all those contradicting videos and posts, I don't know who or what to believe anymore.

To be on the safe side, I've therefore been looking at a 24 inch 4K model from LG, the Ultrafine 4K 24MD4KL-B,
23.7'' UltraFine™ 4K Monitor | 24MD4KL | LG UK
which would effectively scale down the resolution from 4K to 1080p, a 2:1 ratio, to get 'retina' HiDPI, which apparently doesn't suffer from any performance issues. Any scaling outside of that 2:1 ratio comes with some sort of a performance hit. Any 27 inch 4K panel could of course also scale down to Full HD but that resolution would make everything too big on the screen; a 24 inch running 1080p is just right, I believe, and to be honest, I don't need more screen real estate than that (my 27-inch iMac's default looks like 1440p right now, but I guess the size of icons and text would be comparable to Full HD on a 24 inch screen).
This LG model has been made specifically for Mac users, it's basically plug and play, but I would like to be sure I can use my older Macbook with it ; it has Thunderbolt 2 but no USB-C. I'm not really into USB-C and the latest connections yet so I'd like some advice on this. My new MB Pro M1 would connect to the monitor with Thunderbolt 3, check ; however, what's the best way to connect my old Intel MB Pro ?
Really like this display and as it's not one of the latest models, I can get it new for less than 500 euro, down from nearly 800 (about the same in US dollars).

Now, I've also been looking at BenQ with built-in KVM. Apparently, they're serious about Macs since a lot of their displays have a special M-Book (Macbook) mode and their support for Mac users is said to be very good. I'm talking about the PD range, made for designers and I really like the fact that there's a built-in KVM switch.
3 models pique my interest, a 25 inch with 1440p resolution and two 27 inch ones, one 1440p and the other one with more or less the same specs but with a 4K panel.

I already talked about wanting to avoid any kind of performance hit so I was thinking that a 1440 display running its native resolution (1:1 ratio) would have to be scaled : perfection ! But then I came across all kind of posts and articles from people strongly advising against using a 1440p panel for a Mac.
Obviously, it doesn't look as good as retina resolution, but how bad is it really ? I've never seen it so maybe it's not that bad. One Youtuber seems to just contradict all the rest as he returned his 4K panel and got a 1440p one instead. Says native 1440p maybe doesn't look as crisp as 4K scaled down to 1440p but it's really not that noticeable.
Is he full of crap ?

And what about external KVM switches ? How to tell a good one from a bad one ? I've heard that connecting a Mac to a display via a KVM switch/hub doesn't work, it has to be connected directly ? Any truth to that ?

A lot of questions but I would appreciate any feedback. Thanks !
 
I would say to avoid any non-4k display, they just look horrible once you get used to retina levels. I use a 27" 4k set to 5120x2880 and, despite being scaled down, it looks waaaaaaay better than a 1440p. I don't even notice it's not pixel perfect, I have to look carefully.
I can't tell about performance hits, because I have a late 2013 MBP with its infamous nvidia driver bug, so any monitor is a huge performance hit (in fact I hardly use it with an external display any more). But from my experience it mostly depends on the specific mac, ones with integrated Intel graphics or older ones (I guess yours qualifies as "older") are more impacted than they should be because Apple no longer care on optimizing for them. Personally, unless it becomes really sluggish I don't mind.

I don't think the KVM thing is accurate. At their most basic a KVM is just a hardware switch that switches between the connected computers. It's not really any different than you unplugging/plugging from a physical perspective. Some KVMs do have fancier tricks so you can do stuff like use a hotkey on your keyboard to swap between PCs and so there is no delay in letting you use your KB/M after switching. This might cause issues with Macs? I imagine if some models have a problem they'll at least omit Mac from the compatibility list?

Don't mind if it is just a hardware switch, as long as I don't have to plug and unplug cables all the time...
 
Anyone using the Dell Ultrasharp E3421WE with a M1 Mac ? Reviewers seem to rate it as a really good and sharp display, also excellent for Mac. Of course, it's not as good as Retina resolution but pretty good nonetheless.
Maybe anyone could confirm this ?

As far as connections go, I would connect my M1 MB Pro to the USB-C port (delivers 90W so charges the laptop) and I assume I could connect my older mid 2015 MB Pro, which has Thunderbolt 2, to the Displayport on the Dell using a TB2 to Displayport converter cable ?

Nothing is "pretty good" compared to Retina. That screen is only 120 DPI, if it's "sharp" it only means it will look even more pixelated, esp. text (moreover, you can only run it at native res, and UI will look pretty small). But I think they say it only because it's an IPS panel.
A 27" 4k is 180 DPI to start with. And you can scale it and it will always look better than that.

Yes, you don't need a full KVM, you can just use two inputs on the monitors. For the keyboard and mouse a USB switch will suffice, or there are wireless kbds and mice which can connect to two or more computers and switch between them.
If you go 4k (which I strongly recommend) make sure the display has a DP 1.4 for your older MBP and HDMI 2 for the new kid.

I know my only option to have ‘retina’ quality is to get a 27 inch 5k display, and scale it 2:1 to look like 1440p. Or get a 24 inch 4k display and scale it 2:1 to look like 1080p.

Any fractional scaling that’s not 2:1, f.e. 4k getting upscaled to 5k and then down to ‘look like’ 1440p, will take a hit on performance, which I want to avoid.
I really would like to see how ‘bad’ running a 1440p display natively looks.

Are we talking ‘VHS tape on 65 inch 4K TV’ bad or is everyone nitpicking and being a pixel peeper ?

No offence 😁

For a long time I used two 24" 4K LG 24MD4KL displays in portrait orientation. I sit about 36" from the displays so the 187 dpi resolution of these monitors is ideal for me -- the 218 dpi Apple "retina" resolution makes text uncomfortably small for me. I used the pixel doubled 1080x1920 HiDPI mode. Text is very sharp with no blurriness at all. These displays are high quality and extremely bright with decent speakers (for a display).

I then replaced one of the 24" LGs with a 27" 4K Samsung S80A (163 dpi). This is also an excellent display. As you note, many people would say that running this display at HiDPI "looks like 1920x1080" mode makes everything too big. Still, for web browsing, this HiDPI resolution worked for me although the non-integer scaled 2560x1440 was also fine. Text seemed crisp for both. However, web sites were displayed centered on the screen with white bars on the sides -- especially noticeable at 2560x1440.

Next, I replaced the 27" Samsung with an 28" LG 28MQ780-B display (only 140 dpi). This is a 2560x2880 8:9 aspect ratio display -- almost "square". I use it at HiDPI pixel doubled 1280x1440 resolution. I was worried that text might be a little fuzzy but it turned out not to be something I noticed when sitting at 36" from the screen. One web site has a calculator that estimates this display is "retina" for viewing distances greater than 25 inches (compared with 19 inches for the 24MD4KL). It is a perfect monitor for web browsing as web sites occupy the full width of the display. It is about the same height as a 24" monitor in portrait orientation but is much wider. It has a built-in KVM switch but I have never used it.

This setup is optimum for my mostly text-based use (web browsing, editing of translations in Microsoft Word with the original text on the 24" and the translation being edited on the 28"). There is a thread below with more information on the advantages and disadvantages of this "square" display.

The calculator at

https://www.designcompaniesranked.com/resources/is-this-retina/

indicates that a 27" display running at native 2560x1440 with 109 dpi would be "retina" at a viewing distance greater than 32 inches.

I think most people would notice jaggedness in text on that display unless sitting well back from the screen.

Good that you mention the original 27 inch imac…

Since November, I started working freelance. At the company I have been working for, I had a 2013 27 imac with a 1440p display

Worked on it for 5 years, and they were still working great (they got upgraded from 8gb to 16gb of ram and the hdd was replaced by ssd about two years ago) but the point is, they were not retina.
Going back and forth between my work 27 inch non-retina mac and the 2017 27 inch retina imac I have at home, didn’t shock me in any way. I never felt that those 2013 models looked ‘bad’ compared to my retina model at home. In other words, I didn’t really care because apparently, I didn’t really notice it enough to make a fuss about it.

So you will understand that, when I hear people say 1440p on a Mac looks ‘bad’, I’m inclined to take it with a pinch of salt…

In other words, how much ‘worse’ is a 1440p panel of today compared to that non-retina iMac ?

I forget the exact version (10.14?) but at some point Apple scrapped their sub-pixel font rendering which causes text to look like crap on non-retina screens. The screens didn't really get better, Apple just made things worse for non-retina displays. To me it's tolerable, but I'm pretty tolerant. Still looks worse than Windows or Linux though...

So, basically, unless I pay through the roof for a 5K display or settle for a 4K display that looks like 1080p, I’m screwed…

Edit : or am I ?

Found this on Reddit, in response to a question from someone who was as confused as I am about this whole retina thing :

«I don't know if people are exaggerating, overly sensitive or what, but I had the same worries as you.

Just got a M1 Mac mini and was constantly worried because of everything I saw online about people saying MacOS would look like **** on anything lower than the intended ~220 PPI.

Using a 27 inch 1440p monitor right now and the difference from Windows is honestly barely noticeable. I sit about 12-15 inches from my monitor and everything looks fine. Text only starts to look bad when I shove my face unnaturally close to the monitor.

I imagine these people haven't experienced anything but retina displays in the last several years and that's skewing their perception greatly, so if you're used to running windows at lower resolutions 1440p will probably be fine.

Should add that I do a lot of creative work and use a 12.9 in iPad plenty, so while I do see a difference in clarity between the two, it's definitely 100% usable and doesn't detract from the experience vs using this same monitor on a Windows machine. »

Seems logical to me, to be honest. Perhaps people are exaggerating a bit and making a mountain out of a mole hill…

It depends on your perception. I'm happy with 27" 1440p IPS displays. Cheap and good enough. And way more screen real estate than a 24" 1080p (which is the same as a 2160p in HiDPI mode).

I just bought the BenQ PD2700U 27" 4K at $330 on Cyber Monday. So far I'm liking it alot. I have my MBP M1 Max connected to it. USB-C to DP cable.

Depending on what I'm doing, I jump back n forth between 3360 x 1890 and 3008 x 1692, the clarity is just as good as the native 3840 x 2160 (at least to my eyes). Those two scale option feel still feel like 4K. If I select 2560 x 1440 that's when I start to notice less clarity.

As far as the KVM goes, if you're not into cables, you can replicate it with a Multi-input mouse, keyboard & monitor. That's how I do it. If you're going back & forth lots of times a day, you may appreciate the convenience of just switching everything with one button, but I use a Logitech MX Keys Keyboard & MX Anywhere mouse, and a multi-input Samsung monitor, and switching from one to another is super quick & there are no cables showing anywhere.

I kind of have my heart set on an ultrawide monitor now, either that Dell Ultrasharp E3421WE or the BenQ PD3420Q, both 3440 x 1440 resolution. The Dell is curved, the BenQ is flat.
Both are very colour accurate and I hear that curved screens can cause some distortion if you're into professional image processing etc. which I'm not.

Ergonomically, though, I think the curved Dell might be a better option (not having to re-focus your eyes all the time when looking from left to right), unless you tell me the flat display is better for some reason ?
The BenQ has some really nice features and seems to be 'optimised' for the Mac (according to what's mentioned on the site, at least) and it really gets very positive reviews overall (but so does the Dell), but it's about 50% more expensive than the Dell...

I know that I can get a really nice 27 inch 4K display for the money, and that the M1 MB Pro could handle the 'non fractional' scaling without problems, but I also need my older mid 15 inch 2015 MB Pro (also retina) to continue to work flawlessly for at least another 15 to 18 months and I don't think it would do very well as far as HiDPI scaling is concerned.

@mk313 I had a Logitech Craft keyboard and an MX Master 2S but sold them again, too many bells and whistles for me, really. Never really enjoyed working with that combo, especially that mouse (hated it, to be honest) ; all those fancy features and programmable buttons, shortcuts etc. I never used and slowed down my workflow. Being able to switch between computers was nice, but that was about it.
Think I'm going for a normal K650 keyboard and M650 mouse, there's a KVM function in the Dell as well as the BenQ so I'll be alright when using the USB dongle, I think.

Extra question : I would connect the M1 MB Pro to the USB C port (90W) on the Dell monitor, and I suppose the intel Macbook Pro, which has 2 Thunderbolt 2 ports, would connect to the Display Port on the Dell monitor.
Only thing is, I've been looking on the internet but cannot seem to find a Thunderbolt 2 to Displayport male cable. Does such a thing actually exist ?

It doesn't exist. TB2 uses the same plug as mini Displayport. You can get a Displayport to mini Displayport cable and that will work. Displayport doesn't support any of TB2's features (besides video) so there is no point to making a TB2 to displayport cable.

Ok, so the 2015 Mb Pro could push 3440 x 1440 using this cable?

I used one for years, so I guess it exists unless I've been dreaming all along :D
You just got the name wrong, it's Mini Displayport to Displayport.

Good video on the subject. Personally I use 2 x 27" 4k montors with no issues. Plus I have my work laptop and PC connected all at the same time.

I think I must have watched about every video out there on the subject. Still, I don’t know if I should be taking the advice of all those self-acclaimed youtube experts to heart… 😏

Every situation is different and every solution has a trade-off, you're the only one who can tell if you can live with it
