Ranked #3 in Best Thunderbolt 4 Docks
Kensington SD5780T
3 sources1 derived$296.34as of Aug 27

The SD5780T is the display-focused dock: HDMI 2.1 plus Thunderbolt outputs drive dual 4K or 6K monitors, backed by 96W charging and a three-year warranty. Windows Central called it Kensington's best dock yet and XDA marked it Recommended, noting it is well worth it around $300 or less. Its horizontal footprint and original high price are the drawbacks, but recent discounts make it a strong dual-display option.

  • — Up to 96W charging for the host laptop
  • — Built-in SD card reader and broad port selection

How they stack up

Kensington SD5780T

Leans on display flexibility, pairing HDMI 2.1 with Thunderbolt outputs for dual 4K/6K screens — a step beyond the dual-4K HDMI of the Plugable TBT4-UD5. It carries fewer total ports than the CalDigit TS4 and Plugable TBT4-UDZ, and lacks the downstream Thunderbolt daisy-chaining of the OWC Thunderbolt 4 Dock, but its three-year warranty and higher display ceiling set it apart.

Plugable TBT4-UD5

The value alternative to the CalDigit TS4: it gives up some of the TS4's 18-port count and downstream Thunderbolt ports but adds dual HDMI the TS4 lacks, for roughly half the price. It is simpler than the Plugable TBT4-UDZ and Kensington SD5780T but covers the essentials most users need, undercutting the OWC Thunderbolt 4 Dock on price too.
