Does it have to be DisplayPort? I always just use HDMI and I've never had a real issue (the monitor might not turn on until I get past the login screen or something, but things always shake out by the point where it matters). I've used 2014 and 2019 MBPs (the latter with a dongle) I don't know for sure (or why) it would be the port, just offering a data point. I'm currently on a 1080p Dell monitor but I've had the same experience with 4k LG monitors and with at least one other monitor whose brand I can't remember (and even with a couple of TVs, and at least one projector)

The new MacBook pros won’t drive 4k over hdmi for me. However DisplayPort over usb c gets me the whole 4k at 144hz my monitor is capable of, but at the cost of not providing power or forwarding my monitor’s usb ports, so I lost the ability to plug in one port and be finished docking the MacBook in my upgrade. It’s a shame that I ended up having to have a mess of cables for power, mouse/keyboard/peripherals and display when docking, but it works.

Funnily enough, DisplayPort in theory should be a lot better because USB C uses DisplayPort -- both in DisplayPort and Thunderbolt alternate modes. A HDMI monitor and a semi-modern Mac inevitably involves an LSPcon.
