Dell WD22TB4 Thunderbolt 4 Dock

The Dell WD22TB4 is a Thunderbolt 4 docking station providing up to 130W of host charging and DisplayPort MST for reliable multi-monitor output. A community member reports that after the Framework 13 BIOS 3.05 update it "just works" — including the dock's normally Dell-proprietary power button, which now powers on the Framework1.

BIOS update resolves quirks

The WD22TB4 is well known for Dell-proprietary features. On the Framework 13, earlier BIOS versions had the usual closed-lid/display and plug-in fiddliness; BIOS 3.05 eliminated these — the logon screen no longer opens on a closed laptop and the dock power button works1. Keep your BIOS current.

AMD multi-monitor — good choice here

Because this dock uses DisplayPort MST rather than relying on multiple DP tunnels, it is a better multi-monitor choice for AMD Frameworks than DP-tunnel docks like the CalDigit TS42.
