The SD5780T is the display-focused dock: HDMI 2.1 plus Thunderbolt outputs drive dual 4K@60Hz monitors or 8K@60Hz with DSC, 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.

Strengths
  • — Up to 96W charging for the host laptop
  • — Built-in SD card reader and broad port selection
  • — Three-year warranty for peace of mind
Watch-outs
  • — Horizontal design takes up more desk space
  • — Originally launched at a high $350-plus price
  • — Mounting bracket for vertical use is sold separately
OWC Thunderbolt 4 Dock
Ranked #4 in Best Thunderbolt 4 Docks
OWC Thunderbolt 4 Dock
2 sources$229.99as of Sep 25

The OWC Thunderbolt 4 Dock is the daisy-chainer's pick: three downstream Thunderbolt 4 ports and a UHS-II card reader make it a favorite for creative workflows, at a price that meaningfully undercuts the CalDigit TS4. TechRadar praised its construction and flexibility. The lack of HDMI is the main caveat, but for Thunderbolt-heavy setups it is excellent value.

Strengths
  • — Three downstream Thunderbolt 4 ports for daisy-chaining drives and displays
  • — UHS-II SD card reader prized by photographers and videographers
  • — 96W host charging through a single cable
Watch-outs
  • — No HDMI port, so displays need DisplayPort or Thunderbolt
  • — USB 2.0 port is a dated inclusion among faster connections

How they stack up

Kensington SD5780T

Leans on display flexibility, pairing HDMI 2.1 with Thunderbolt outputs for dual 4K@60Hz screens or 8K@60Hz with DSC — 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.

OWC Thunderbolt 4 Dock

Sits between the value Plugable TBT4-UD5 and the flagship CalDigit TS4: it adds three downstream Thunderbolt 4 ports for daisy-chaining that the Plugable TBT4-UD5 lacks, while undercutting the TS4 on price. Like the TS4 it has no HDMI, where the Plugable TBT4-UD5 and Kensington SD5780T include it, and it carries fewer total ports than the Plugable TBT4-UDZ.
