Features | USB-C Docking Station Turns Your Laptop into a Multiport Workstation

This professional workspace dock dramatically expands the potential of your MacBook or Windows laptop by adding 12 ports to its USB-C or Thunderbolt 3 port. Not only does the U442-DOCK24DL3A allow you to transmit 4K video to three displays at the same time, but you can also add USB peripherals, connect to a Gigabit Ethernet network, charge your laptop and more.

Transmits 4K Video and Digital Audio to 3 Displays Simultaneously

Three HDMI and two DisplayPort (DP) outputs individually support 4K video resolutions up to 3840 x 2160 at 60 Hz with High Dynamic Range (HDR), 36-bit Deep Color and 4:4:4 chroma subsampling. The dock supports combinations of HDMI + HDMI + HDMI, DisplayPort + DisplayPort + HDMI or HDMI + HDMI + DisplayPort and transmits 4K @ 60 Hz video to all. This allows you to display the image from the host computer (including M1/M2/M3 MacBooks) on all monitors, extend your host desktop across all with different windows open on each, or combine all into one large display as a video wall.

USB Hub Ports Connect Keyboards, External Storage and Other Peripherals

One USB-C and one USB-A each support fast USB 3.2 Gen 2 data transfer rates up to 10 Gbps for quickly transferring files between external storage devices. Three USB-A hub ports support USB 3.2 Gen 1 data transfer rates up to 5 Gbps for connecting a mouse and keyboard, USB headset or other devices.

PD Charging Port Charges Host Device via AC Wall Charger

The USB-C Power Delivery (PD) port supports power output up to 100W, which is more than sufficient for charging and powering the connected source device, such as a MacBook Pro, Windows laptop or Chromebook. Just connect the device's wall charger to both the USB-C PD port and an AC outlet.

Accesses a Wired 2.5 Gb Ethernet Network

The RJ45 port offers access to a 2.5 Gbps Ethernet network when Wi-Fi is unavailable or when a wired connection offers faster speeds. Connect using a UTP cable (sold separately), and enjoy true 2.5G Ethernet speeds for fast data transfers.

Connects Speakers, Microphone and Other Audio Equipment

The 3.5 mm mini stereo jack is convenient for connecting speakers, headphones or a microphone to your workstation. You can listen to music or record the latest episode of your podcast.

Anti-Theft Lock Protects the USB-C Docking Station When You Aren't Around

Connect a user-supplied computer/laptop security cable lock (not included) to this port to protect the dock against theft.
