I've a 27" iMac with a 5K display. I don't think I'd want anything larger as you're supposed to sit close to your display rather than have it at a distance, and if I ever need more screen real estate, I change the scaling factor in System Preferences. Anyway, that was just to say that now I've gotten used to a HiDPI display with fantastic, accurate colour, I can't go back. I'm running a little low on funds and considered selling the iMac in favour of a 2018 Mac mini with a 24" 1080p display — can't do it. I think a lot of people are spoilt by their Retina-display iPhones, iPads, and MacBooks; or their HiDPI Android phones and tablets. Now that I've been spoilt by a large Retina display, I'm ruined for anything else, even 4K at 43".
