The Kensington SD5780T is an 11-port Thunderbolt 4 dock with a notable specification advantage: HDMI 2.1 output (capable of 4K@120Hz and VRR) and 2.5 Gbps Ethernet — both uncommon on docks at launch. It provides 96W of power to the laptop and has three Thunderbolt 4 ports total for flexible peripheral and display expansion. The UHS-II SD card reader and front-panel USB-A charging port (5V/1.5A) add everyday convenience. Note that MacBooks with Apple's base M-series chips (non-Pro/Max) are limited to a single external display through this dock regardless of port count.
