Got a MacBook Pro (16-inch, 2019) weeks ago and bought a LG monitor (https://www.amazon.com/gp/product/B07YGZ7C1K). The brightness setting bothered me for 2 weeks as neither the Mac OSX nor LG's onscreen control software can set the brightness for the external monitor. The external monitor brightness changes every time I open/close the macbook lid. Thanks to both ddcctl and MonitorControl, I can finally set a fixed brightness. Wondering why big corps fail to provide the basic features while some open source software can do?

How have you found MacOS' font rendering on the 1440p display? I've been having all sorts of trouble in some applications having terrible font rendering while others are perfectly fine running at the monitor's native resolution.

The LG UltraFine displays do support this (in fact there's no OSD/controls on the physical things at all) so it definitely is possible and something LG can do

Automatic dimming only works in the recently refreshed (mid 2019) UltraFines. It doesn't work in the original models sold from 2016-2019, despite advertising and product documentation claims that it does.

I have the exact same setup and same issues!! So frustrating.

Have you tried MonitorControl? It solved my problem. I guess Lunar should also work.

Yes, I ended up just using Lunar. But no, never tried MonitorControl.
