I actually have a 24" 4k (samsung) I use with a 2012 mac mini (via a displaylink 4k adapter). I am not young (45) and find that I can use it at 4k generally but sometimes i find I need to drop it to 1080 (HiDPI) when eyes are tired. I wouldn't really recomend it but I think 27" is a good size. I went 24 as I really don't have the space for a 27.
Got a tip for us?

Mac mini 2018 paired with two LGs Ultrafine UP850-W , using the usb c ports and everything is fine. Super happy!
Bought them through Amazon.fr (400 euros each)

I've just got a pair of LG 27" UP850-W's as well for my 2018 Mac mini. Running smoothly, even with transparency on. I've turned it off though as I like solid menu bars. It's a 16GB i5. I had a pair of Dell 27" 2560 x 1440's before which run great, but the 4k looking like 2560 x 1440 is much crisper. I can also hook my PS5 up to one at 4k, and PC up to the other one. I'm Super happy also.
