DDC/CI, Mojave and Dell Monitor?

I just learned about DDC/CI. I have the 2018 Mini and a Dell U3415W. (I want a 4k, but I like the width of this, so waiting for the right 5k).

I've come across a few DDC/CI apps. None seem to work. My monitor is supposed to support DDC/CI. I am connected via the HDMI port (though I have also tested the MHL port). I'm not sure if it is my monitor or if it is Mojave.

Has anybody had any luck with a DDC/CI app (ideally for brightness, contrast AND volume) on Mojave?

MonitorControl. I've used it on my UP2715k and on my current UP3216Q. Works like a charm. https://github.com/the0neyouseek/MonitorControl/releases
I've never been able to get this working on a Dell UP2715k and your post gives me hope. Did you have it connected with the dual MiniDP for 5k?

I'm using its USB 3 cable too. MonitorControl doesn't seem to be getting information from the display. Its brightness/volume sliders just show as being at their min level and adjusting them has no effect. In the monitor's OSD, under "Others", DDC/CI is enabled. I tried a different Dell monitor and that did work, but I was thinking it wasn't compatible with the UP2715k until seeing your post. Thanks for any suggestions.

Yes, I connected it used the dual MiniDP method, when I still had my 5k iMac.

Not sure what to make of this.

Brought down my 2011 Mac mini (fresh install of High Sierra) and Monitor control works fine over HDMI.

Switched the same HDMI cable to my 2018 with Mojave and it does not work at all.

Thank you. Just tried on LG 27UK650, and works great.
