I have a Thinkpad P1 gen 4 running Fedora I’m going to be using as my desktop replacement, and I’m looking for a Linux friendly dock.
I don’t need the dock to do much. Ideally, it could drive 2x 4K DisplayPort displays, have a 2.5Gb+ Ethernet port, and a couple USB-A ports, but 2x 2K DisplayPort and 1GbE work too.
Tb3 is supported on that, go with it, found one for 129 or so on Amazon.
Tb3 is dramatically better than usb-c in every way, mostly because usb-c means different things to different vendors while tb3 is a genuine standard.
Edit: shit you got tb4, if you get a tb4 caldigit you're set for life but they're expensive af, love mine. They're a single cable solution for everything, 2x 4k easily, think I'm at 4k+5k and it's fine.
