How to enable "larger text" scaling slider on a 2k monitor?

Question

I have a Mac Mini (late 2014) connected to two Dell U2515H monitors, which have 2560x1440 resolution.

Problem: everything (macOS UI elements) is too small at this native resolution.

I was able to force "HiDPI" mode, using the command below.

sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool true

The result looks nice and sharp, BUT everything is too big when using the 1280x720 HiDPI resolution.

What I need is a scaling in between these 2 options (100% and 200%).

It seems that macOS has this option (several levels of scaling available) on their iMacs and MBPs:

Is there a trick to enable this slider with my monitors?

Apple only does this on their Retina displays, and a few licensed ones. There is a hack for adding HiDPI mode with a terminal command, but it only works with those specific monitors. Sorry! — Charlie Welsh, Oct 1, 2018 at 5:13
I was able to create a 1080p HiDPI resolution using SwitchResX, which I think is equivalent to the built-in scaling shown in the screenshot. Text looks sharp, but overall I'm not happy with how poorly macOS handles my monitor resolution. The scaling is way better on Windows. — Sébastien, Apr 29, 2020 at 8:06

Search for ResolutionTab on the app store. It's only a couple of bucks and works well on my 2009 MacPro.
