There is ongoing work to fix DP Monitor control via slider and hot keys here: Waydabber's fork of MonitorControl.
With the latest build I have had good luck with my Dell U3818DW on Big Sur 11.5.

I sometimes have to replug the monitor connected via USB-C after launching the app to get things to work correctly. Currently there are no Release build downloads. You need to:
- Check out the GitHub repo
- Build with Xcode
- Archive and export/copy the result

This might work on HDMI, but I have not tested it.

Is it HDMI only? Or does it work with Display Port too?

Edit: The Readme says it only works on DP. Is HDMI the fix you are talking about?
