Kensington SD5780T

4.3

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.
