Anyone rocking a Dell Dock WD19 (no suffix!) with a 4K display? (lemmy.ml)

apologies if this community is just for news, feel free to remove.

anyhoo, having trouble getting my WD19 dock to display 4K@60Hz. the laptop is a Dell Latitude 5290 2-in-1, it supports DP-Alt over USB-C (no Thunderbolt) and a direct connection from the laptop to the screen works. however, attaching the monitor to the dock via DP, and then connecting the dock to the laptop with its USB Type-C cable with PD yields 4k@30Hz max.

Dell has a bunch of newer WD19 models (TB, S, etc.) but I don't have those.

it is possible that my hardware is faulty as I've sourced it nth-hand, but before I start replacing it one-by-one, maybe someone got it to work? thanks.

that's one hell of an effort, thanks a bunch! will take me some time to try some of those things... the dock has a normal DP 1.2 connector, I'm using the same cable my desktop (RX 570) is using and has no issues getting 60 Hz. haven't tried Dock USB Type-C - DP.

the dock has an integrated USB Type-C PD cable that I use for the laptop, so that's not replaceable. charges fine, can take up to 65 W (it doesn't use even a third of that).

I was guessing this has something to do with cables. sadly, I can't afford to buy & try out different cables but I'll do my best with this new info, much appreciated.
