The Kensington SD5550 t Thunderbolt 3 Dual Display Docking Station is currently on sale by Amazon for $215.10. Usually, as you’ll see at B&H, $260 is good for a $45 rebate today, the first one we’ve tracked, and then it’s at a new all-time low. With two DisplayPort outputs, the Kensington Dual Display Dock lives up to its name by being able to drive two 4K monitors at 60 Hz. There are many other I/O options, including three USB-C slots, three USB 3.0 ports, and a Gigabit Ethernet input. All come equipped with a 135W adapter. 4/5 stars rated.
