TLDR What notebook and and docking station seamlessly supports 2 large external monitors?

My personal computer is an Asus zenbook (UX390) with "plugable" usb-c docking station.

I have a Philips 3840x2160 monitor and a BenQ 2560x1440

With windows10 both external monitors worked beautifully

Ubuntu 20.04 there was just no way to get 2 monitors working with this setup. I easily spent 40 hours trying things, updating displayport drivers, reading forums. 2 monitors was not to be be

Then work gave me a Thinkpad T14 Gen 2 with its own usb-c docking station. Again windows is beautiful with 2 external monitors.

Ubuntu 22.04 on exactly this hardware sort of, kinda supports 2 monitors. The 4k monitor will just go blank for 5 to 60 seconds. If I want to watch a movie I switch off the second monitor, otherwise the 4k monitor will randomly blank.

I can't read any more forums telling me which driver to try updating, or which configuration file must be tweaked. The joy and curse of Unix is that solutions never die. They can be 15 years out of date and completely irrelevant, misleading, but they never die.

Has anybody had any success connecting 2 large external monitors to a notebook running Ubuntu.

If so exactly what hardware configuration? i.e. Notebook model and docking station.It has recently been suggested to me that usb-c is my problem and I should be using thunderbolt.

I want to buy a new computer but I want it to support Ubuntu and 2 monitors reliably.

I really do not love Windows.
