Can anyone share any experience of using 2018 Mac mini to drive 3x 4K displays using the internal graphics only? I’m considering this configuration (no heavy video editing - desktop apps only) as a replacement for a CMP.
I would assume that's less resource intensive, so sounds like it'll be fine then, given enough memory.This would be driving 3x 32" 3840x2160 displays at native resolution
I have a a 2018 mini with 2x 4K displays, using just the iGPU.
I think a lot will depend on which displays you want to use. Running at the 'native Retina' (i.e. 'looks like 1920x1080' on a 3840x2160 panel)
What options do you see in display panel? What does it default to, native 2160p one?
How do you access the "looks like...." resolution?
I'm asking because on my 1440p display (over hdmi), to get the "native retina" look i would need to set a 720p resolution...but it looks like crap, so it's not doing the 4x interpolation apparently
The default on these displays (and I believe most other displays with a suitably high PPI - certainly it's true on my 2018 MBP15) is "retina" mode. I have to hold Option and click "Scaled" to get the old-style list of resolutions, which has both "retina" scaled modes (all of which will end up sending a 3840x2160 image to the display), and the non-retina approach (where it's sending the resolution you pick to the display).
I'm guessing that you'd need the display to be no bigger than ~17" or so, for macOS to detect it has being "high DPI" and offer the retina scaling mode.
hmm, are you using DisplayPort or HDMI?
I don't see those "low resolution" resolutions on my screen....still, it's a 27" 1440p display...at least 720p HiDPI should be available somehow, but i can't see it. It only lists it as 720p..(not even 1280x720). Default resolution for display is 2560x1440, but it looks...nothing as sharp as yours.
I'm using DP, but your problem is that you're using a low PPI screen. 2560x1440 @ 27" is ~109PPI, using it at 1280x720 would make everything on screen comically big, and still wouldn't look that great, because the physical pixels are still quite large/low density.
As I said - the "Retina" modes only seem to be available (and only really make sense) on displays with reasonably higher than "normal" PPI (normal for macOS being ~110).
That would depend on the size of the screen, really. It's the "default" for macOS, certainly, because non-even-2x scaling is a performance issue, but even on my 24" screens, I find "looks like 1920x1080" to be a little too low (i.e. everything is a bit too big). One of these days I'll get around to ordering an eGPU (not much choice in-country so I have to deal with international payment + shipping + customs etc), and then I'll run them at the next 'stepping' up, "Looks like 2304x1296" - that's basically perfect, size-wise IMO, but it's too much strain to run two of them on the iGPU (it works but you get lag and weirdness).So i guess on a 4K screen, 1080 in hidpi is the sweetspot, right?
Yup, the 'default' setting.your screenshot above is 1080 hidpi, not 2160 native yes
I don't think I understand. Why would you want an AIO to use with a mini?THIS would be a nice AIO to be used with a Mac Mini

Also, 4K @ 27" is a bit crap PPI wise.
A 2018 Mini doesn't have 'native' DP or Mini DP (earlier ones had TB1/2 ports which can operate as regular Mini-DP ports), but a USB-C to DP cable would work, if you wanted to go that way.
I haven't tried HDMI (I use mine with a TB3 to dual DP adapter to save a TB3 port) but it definitely seems more people report issues (particularly relating to 4k/60hz operation) with HDMI than DP.
You probably need to unplug the cable to change HDMI options (same is true for DP options - you can't enable MST mode while it's plugged in).
https://github.com/the0neyouseek/MonitorControl works for me.I found an app that did it a while ago (I’ll try to find it for you) but I stopped using it, I seem to remember it not being very reliable.
I found that I had to restart the program after granting it access to whatever it needed in System Preferences.works, thx!
don't know if it's because i switched from HDMI to Displayport, but it finally works!
Your monitor may have different settings between the two inputs if you tweaked them there before. Alternatively depending on many things like phase of the moon etc. the DisplayPort may be on v1.1 and have less bandwidth or HDMI may have picked a different encoding (4-2-2, 4-2-0, …) leading to different colours.as i sidenote, the calibration over DP is different than HDMI.
also the calibration wizard creates a profile that it's identical to the default one.
in case of HDMI, the custom one was a bit darker, more contrast i believe.
it looks fine...i wonder how a 27" 4K interface looks like default (1920x1080 hidpi) on a mini, so i can compare to my 24" and see if it makes sense to move to 27"....i posted a new thread on this but no replies yet...
