Thunderbolt 4 connectivity

This docking station provides three Thunderbolt 4 ports for high-speed data transfer and display output. It also includes three USB-A 3.1 Gen 2 ports for legacy peripherals. A 2.5G Ethernet LAN port and a 3.5mm audio jack complete the wired interface selection. The unit is finished in black and listed as new condition.

Professionals needing multi-display support

The dock supports 4K 3840 x 2160 resolution at 60 Hz for external monitors. It suits users who require a single-cable connection for power, data and video on compatible devices. Buyers whose laptops lack Thunderbolt 4 capability will not gain the described bandwidth or display performance from this unit. Those needing more than three downstream Thunderbolt connections should consider alternative solutions.

Three Thunderbolt 4 ports

The defining specification is the count of three Thunderbolt 4 ports on a single dock. This determines how many high-bandwidth devices or displays can be attached simultaneously without daisy-chaining. Verify that the host system supports Thunderbolt 4 to utilise the full 40 Gbps potential per port. The 2.5G Ethernet and USB-A 3.1 Gen 2 ports provide additional connectivity for wired networks and standard USB accessories.

Questions about this item

Does the Microsoft Surface Thunderbolt 4 Dock T8I-00001 run silently when powering a laptop all day?

The dock has no fan and operates silently during continuous use.

Which ports must my laptop already provide for the Microsoft Surface Thunderbolt 4 Dock T8I-00001 to function?

Your laptop needs a Thunderbolt 4 port to connect the single upstream cable that carries video, data and power.

Will the Microsoft Surface Thunderbolt 4 Dock T8I-00001 drive my older 4K 60 Hz monitor at 3840 x 2160 resolution?

Yes, each Thunderbolt 4 port supports 4K 3840 x 2160 at 60 Hz, so an older 4K 60 Hz display works at its native resolution.
