There's nothing unusual about expecting to be able to use a 4K display comfortably at 4K resolution. The exact same dialog is 1560 pixels wide on the 4K display, but only 780 pixels wide on the Cinema Display. To see what UI scaling actually does, check the two images above. The pixel-size of the UI remains constant. With UI scaling off, the resolution of the display is modified using the "Scaled" option.
It's a 1920 x 1200 display, and so macOS has correctly not enabled UI scaling for that display: I also have an Apple LED Cinema Display attached to this machine. It just changes the pixel-size of the text, etc. Modifying that option does not change the display resolution (verified using the monitor's on-screen menu) - it will always be 3840 x 2160.
I choose to have the text at a larger size to make it easier to read.
The "Scaled" option allows you to choose how much the UI is scaled up. This is what the "Displays" System Preferences pane looks like for this display: The Mac enabled UI scaling without me having to do anything.
I'm writing this message on a 2013 Mac Pro using a 27" 4K (3840 x 2160) display, which is running at the full native 4K resolution. The issue is that the 2018 Mac Mini is failing to enable it when it should. It's been needed ever since Apple introduced so-called "retina" displays. UI scaling is a feature of macOS designed to solve this exact problem - of text and UI widgets appearing too small on high resolution displays. The OP seems to have a good understanding of how 4K displays work. Sudo defaults write /Library/Preferences/ DisplayResolutionEnabled -bool false If you decide you want to revert the change above, just use this terminal command: UI Looks like: 1920x1080 (1080p FHD - Full High Definition) Resolution: 3840x2160 (2160p 4K UHD - Ultra High Definition)
This is what I see (I connect to the TV via an A/V receiver): Once you have found one that works for you, you can verify that you're getting the right resolution by clicking the Apple Menu in the top-left, selecting "About This Mac", then the "System Report" button, then clicking "Graphics/Displays" in the list on the left. You may have to experiment a bit to find the best one, but for me "1920x1080 HiDPI" enabled the native 3840x2160 resolution and scaled the interface up to look as if it were 1920x1080. You should see a number of new options, some of which will be marked "HiDPI". Hold the Option (alt) key and click the "Scaled" radio-button. Reboot the mini and open System Preferences -> Displays. Sudo defaults write /Library/Preferences/ DisplayResolutionEnabled -bool true
Enter this command as an administrator user, then type your password (the cursor won't move while typing.
I don't know why that is, it is a 4K display after all, but the good news is that you can manually enable scaling using the terminal. The problem is that macOS isn't enabling HiDPI resolution scaling. I could select the native resolution, but the UI was unscaled and so everything was microscopic even on a 50" screen. I had the same issue with a new 2018 mini connected to a Sony 4K TV (native resolution 3840x2160).
