Plugable Introduces Upgraded USB-C Triple Display Docking Station With 4K Support On All Three Outputs

Mac users please note: This docking station is only compatible with macOS High Sierra 10.13.3 and earlier versions (10.11.x – 10.13.3). The upcoming update to macOS 10.13.4 will permanently disable the dual DisplayPort outputs.

After the great response to our original award winning UD-ULTCDL Triple Display Dock in May of 2016, we listened to power-users’ feedback and feature requests and are excited to announce a second Triple Display Docking Station with 4K support on all three outputs and a new port configuration with the addition of two DisplayPort++ 1.2 ports alongside the single HDMI 1.4 port.

The new Plugable UD-ULTC4K 4K Triple Display Docking Station provides up to three additional 4K display outputs via a combination of USB-C DisplayPort Alternate Mode (“Alt Mode”) converted internally to HDMI 1.4 with support for HDMI displays up to 4K@30Hz, and the DisplayLink DL-6950 USB graphics chip powering the dual DisplayPort++ ports and supporting resolutions up to 4K@60Hz. The dock also provides compatibility systems up to 60W of power via USB-C Power Delivery (“PD”) standard to charge your laptop or tablet while adding Gigabit Ethernet, wired headphone and mic input/output, and expanded USB device connectivity with 4 USB 3.0 Type-A ports and a single USB 3.0 USB-C port. All through a single USB-C cable.

The UD-ULTC4K is the first device of its kind to combine these three powerful, unique, and complementary technologies to unleash the potential of your computer while offering three 4K capable outputs simultaneously. The Plugable USB-C 4K Triple Display Docking Station is available for purchase in the USA and shipping now.

Designed for laptops and tablets with USB-C or Thunderbolt 3 the dock utilizes cutting edge USB 3.1 technologies in conjunction with the latest features of our UD-6950 dual display 4K docking station. Because USB-C features are optional and not supported by every USB-C laptop, before buying please check our compatibility tables on the product page to make sure your Mac, PC, or Chromebook is compatible. Compatible systems include the current versions of the Dell XPS 13 & 15, HP Spectre x360 13 & 15, Lenovo Yoga 720 13″; 920, Apple MacBook 12” with USB-C, MacBook Pro 13″ and 15″ with Thunderbolt 3, and many more. Note that older systems with only familiar USB “Type A” ports will not work, even with a converter cable. You must have one of the new generation USB Type-C or Thunderbolt 3 systems to take advantage of this docks features. Please note that while the DisplayPort outputs of the dock can be converted to other connectors (HDMI, DVI, VGA), adapters are sold separately.

Also we’re excited to announce that Mac users running the latest macOS 10.13.x High Sierra can now enjoy vastly improved performance over DisplayLink USB graphics than in the past. For more information on performance on Mac systems see here.
