Possible to run 4 monitors on a Mac mini?

[dillonm]

Does anyone know if its possible to run 4 monitors on a Mac mini? Specs are below... I am currently running dual monitor at 2560x1440 and was hoping to add two more same resolution. If that is not possible I would be ok with just three monitors... am also curios if that is possible at the same resolution listed above. Thanks


Mac mini (2018)
3.2 GHz 6-Core Intel Core i7
32 GB 2667 MHz DDR4
Intel UHD Graphics 630 1536 MB

Three monitors is the limit of the UHD 630 (3x @ 1440p should work). If you want more (4+) monitors you will need an eGPU.

Hi. I am now looking into getting an eGPU. Information online seems a little scattered so I thought I’d ask you. Is there a certain one that you would recommend? This setup is strictly for trading. No gaming whatsoever.
Also, would I hook up all four monitors to the eGPU or two to the Mac and two to the GPU?

For maximizing screen space I'd actually suggest bigger higher resolution monitors instead of getting an eGPU to drive more monitors. My coworkers have started using 40" 4K TV's for their work. Or if you want something intended as a monitor maybe a 3840x1080 ultra-wide.


As for an eGPU, connect 1-2 monitors to the Mini and the rest to the eGPU.

A year ago the obvious answer to just drive more screens would have been one of the all-in-one RX 560s such as a Sonnet Breakaway Puck or PowerColor Mini, but both have since been discontinued are only available used.

Looking at what is available new I'd suggest either a Sonnet Breakway Box 550W (best value) or an Akitio Node Titan (business professional) for the enclosure.

For the GPU card I'd suggest either an RX 570-4GB or an RX 5500-4GB. Most have 3x DisplayPorts (plus an HDMI and sometimes a DVI). An RX 560 could also work, but will support fewer displays while costing almost as much.

That’s a good idea. Now you got me looking at a way to run dual 49” monitors. I’m curious, do you think there’s much of a noticeable difference if I went from 1440 27” to a 1080 49”?

 

[padams35]

4K @49" would be equivelent to ~1200p @27" or 1440p at 32.7". Unless you are planning to sit 20% farther away I think you will notice a difference.

(1080p @20" is equivalent to 1440p @27" is equivalent to 4K @ 40.5")

I’m all over the map with my decision making lol

I’m now contemplating just adding a third 27” 1440 monitor. But I fear it will be too much for my i7. Thinking about upgrading to the M1 Mac mini but according to apple website only capable of two monitors? It also says on the website that the i7 is only capable of two monitors but you mentioned it should be able to handle a third. Will the M1 support three monitors at 1440?

Would my Mac mini run dual 49” monitors @ 1440?

 

[padams35]

Dual 1440p - yes, easily on both models.

Triple 1440p - easy on a 2018 intel, but not natively possible on M1 (maybe with trickery: https://www.macrumors.com/2020/11/24/m1-macs-able-to-run-six-external-displays/)

If you don't need color acuracy badly, I would suggest a 55" 4K LED/OLED TV.
Better have the curved one. One 55" TV is equivalent to four 27" monitors.
