Plugable's flagship DisplayLink docking station has gotten a big upgrade. The Plugable USB-C Triple 4K Display Docking Station (UD-ULTC4K) was designed from the ground up based on five years of collected user feedback to include improved charging capabilities, more flexible display options, an SD card reader, and a front-facing 10Gbps, 20W USB-C port to fast charge your phone and other devices.

This second-generation dock provides a better customer experience with 3x DisplayPort ports and 3x HDMI ports to match your monitors. And of course, whichever you choose—HDMI or DisplayPort—you’ll get resolutions up to 4K @ 60Hz on all three monitors with USB4 / Thunderbolt 4 hosts via Alt Mode. But monitor ports weren’t the only thing to get a boost. The UD-ULTC4K comes with 100W charging to better accommodate larger laptops. This docking station is a one-stop shop for all peripherals users may need, connecting all 13 ports to the laptop with a powerful 10Gbps USB-C cable.

Note: New and innovative products aren't without compatibility concerns, it is important to read the information below for details regarding display output types and system requirements.

Not all USB-C ports offer DP Alt Mode or PD charging. Having a fully compatible USB-C, USB4, Thunderbolt 3, or Thunderbolt 4 port is required for this docking station, it will not work properly when adapted to USB 3.0. The UD-ULTC4K supports Windows 11, 10, 8.x, and 7 and macOS 10.14+. Chrome OS, Linux, and some older macOS versions are not supported.

Feature Packed

4K Your Way

Compatible with Windows, Mac and ChromeOS, the Plugable USB-C Triple 4K Display Docking Station (UD-ULTC4K) is the computer docking station built for adding monitors.

Featuring 3x DisplayPort ports, and 3x HDMI ports, now you can standardize on one or use a mix of both. And HDMI or DisplayPort will give you resolutions up to 4K @ 60Hz on all three monitors when connected to a compatible host computer with USB4 / Thunderbolt 4 hosts via Alt Mode.

Ports a Plenty

This Displaylink docking station has a front-facing USB-C port for 10Gbps data transfer and 20W charging to accommodate your phone or other devices.

Speaking of peripherals, the UD-ULTC4K also has 4x USB 3.0 ports for 5Gbps data transfer rates, an SD Card Reader, a Gigabit Ethernet port, and separate audio in and audio out ports. Requires installation of DisplayLink Drivers—automatically downloaded with Windows and ChromeOS updates, manual update on Mac

Power Delivered

Power Delivery—charging your laptop through a USB-C port—can get confusing. How much power is enough? How much is too much?

The UD-ULTC4K has you covered. With 100W charging (96W certified), you have enough power to charge just about any laptop—even under a heavy workload. And if your laptop needs less power, the dock communicates with your computer to negotiate the perfect charge level.

To strictly comply with 100W regulatory limits with margin, Thunderbolt certification limits to charging to 96W.

Hardware Compatibility Notes

USB-C is a new standard with much versatility. As a result, compatibility information is complex. Some USB-C systems support Alt Mode video output, while others do not. Some can be powered and charged through USB PD, while others cannot. It is very important to check the compatibility of your device before purchase.

The "Specifications" tab of this product page contains detailed compatibility notes for a variety of laptops, tablets, 2-in-1s, motherboards, and mobile devices that is updated regularly.

Port Features, Limitations, Notes, and Terminology

Alternate Mode (Alt Mode) is a new feature introduced with USB 3.1, allowing USB cables to carry video signals directly from a device over a USB cable. Alt Mode video comes directly from the graphics card or integrated graphics processor on a device, meaning outputs from an Alt Mode video port have the full graphics acceleration of your system.

HDMI 2.0 allows for a maximum output resolution of 4K 60Hz (3840x2160 @ 30Hz). Lower resolutions such as 1920x1200, and 1920x1080 (1080p) are supported at 60Hz.

DisplayPort 1.2 allows for a maximum output resolution of 4K 60Hz (3840x2160 @ 60Hz). These ports are Dual-Mode (DP++), allowing the use of simpler and less expensive adapters to convert the DisplayPort outputs to other display types, like DVI. or VGA. However, as a limitation of the technologies used to provide these video ports, multi-stream transport (MST) is not supported and conversion to dual link DVI is not supported.

DisplayLink is a technology that allows compressed data of various types to be sent over USB data connections. The DisplayLink DL-6950 chipset in this docking station connects all the data and video connections, other than the "Display 1" outputs, on this dock.

There are a few important limitations of DisplayLink technology. DisplayLink uses a proprietary compressed video stream that is partially generated by both your computer's CPU and GPU, and is a "virtual" video adapter. Because the video is compressed and packetized as data, then reassembled by the DisplayLink chip, the pacing of new frames of video can be inconsistent, particularly if large portions of the content being sent through DisplayLink is changing (such as with video playback).

Because of how DisplayLink provides video, video outputs provided by DisplayLink technology should only be used to display content like office applications and web browser windows, not games or video content.

HDCP is not supported, this means protected content such as Netflix, Amazon Video, YouTube Premium, Hulu, Blu-ray videos, and other protected content, either may not work or will play at a lower resolution, depending on the content provider.

Some USB-C ports on PCs and Macs are labelled as Thunderbolt 3, Thunderbolt 4, or USB4 ports. Thunderbolt 3, Thunderbolt 4, and USB4 ports are USB-C ports with additional functionality that are also compatible with this docking station.

USB Power Delivery (USB PD) is a standard introduced with USB-C that provides enough power for many mobile devices and laptops. This dock is able to supply up to 100W (96W Certified) of power to a host. Some laptops may require more power than this, such as high end gaming laptops or desktop replacement workstations. These systems may still charge, but at a slower rate.
