Dell WD22TB4 (Thunderbolt 4 / 130W Power Delivery on Dell Systems / Quad Display / Gigabit Ethernet) Review
The Dell WD22TB4 is a Thunderbolt 4 docking station supporting up to four external displays through Thunderbolt, DisplayPort 1.4 and HDMI 2.0, with 130W power delivery to Dell systems, 90W to others, and Gigabit Ethernet.
Dell's WD22TB4 is the enterprise-fleet answer to the dock question, built for IT departments standardizing across a mix of Dell and non-Dell laptops, with four-display support that goes beyond what most single-user docks in our catalog offer.
Four Displays Is the Headline Feature
Most docks in our lineup top out at two or three displays, the WD22TB4's four-display support via its mix of Thunderbolt, DisplayPort, and HDMI outputs makes it the pick for genuinely display-heavy trading desk or analyst-style setups.
Built for Mixed Dell and Non-Dell Fleets
130W to Dell systems and 90W to everything else isn't a limitation, it's a deliberate design choice for IT environments where the same dock needs to serve laptops from multiple vendors without buying different docks for each.
Comparison to Alternatives
Against our own CalDigit TS4, the TS4 is the better single-user, cross-platform pick with simpler setup, the WD22TB4 is built specifically for four-display fleet deployments and Dell-optimized charging. Against Kensington's SD5000T5 EQ, also new here, the Kensington pushes higher power delivery and Thunderbolt 5 speeds, the WD22TB4 counters with more total displays supported.
