USB 3.1 Type-C is revolutionizing connectivity. We’ve designed our USB-C 4K Triple Display Docking Station to showcase what this new standard is capable of with flexibility and scalability in mind. More features, less compromise.
When attached to a fully compatible USB-C or Thunderbolt 3 system, the UD-ULTC4K supports Windows 10 and 8.1, macOS 10.13.3 and earlier and some systems with ChromeOS.
The dock's main HDMI port utilizes USB-C DisplayPort Alternate Mode (converted internally to HDMI for maximum compatibility) which has a direct pipeline to the host graphics processor (GPU), and the connected monitor will perform as if natively attached to the system. Video and photo editing and other resource-intensive tasks are possible assuming that the system's GPU capabilities are sufficient for the application being used.
The 2nd and 3rd graphics outputs (DisplayPort++) are powered by DisplayLink DL-6950 USB graphics technology which leverages the host GPU & CPU to render the image. These outputs are recommended for web/productivity software; not recommended for gaming.
Maximum resolution via Alt Mode output is 3840x2160@30Hz (4Kp30) as outlined in the HDMI 1.4 specification. 2560x1600, 1920x1080 (1080p) and lower resolutions will display at 60Hz.
The DisplayLink graphics supports dual monitors up to 4K@60Hz (3840×2160@60Hz) each and a single 5K@60Hz monitor when connected to displays that support the desired resolution. DisplayPort equipped monitors and the DisplayPort cable must support DisplayPort 1.2 specification in order to support 4K@60Hz. While backwards compatible with DisplayPort 1.1 standards, the resolution will be limited to 4K@30Hz if the display or cable does not support DisplayPort 1.2 specifications. Does not support gaming, DisplayPort MST daisy-chain connections, nor Dual-Link DVI conversions.

USB 3.1 Type-C Compatibility Overview
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 via USB-C PD, while others do not.
Information on specific system compatibility will be updated online as we test more systems internally, and we welcome compatibility reports from users as well.
Compatible Systems (Alt Mode, PD, & DisplayLink)
Some of the best examples of systems which currently support Alt Mode, PD, and DisplayLink are the Dell XPS 13" 9350/9360, Dell XPS 15 9550/9560, Dell Precision 5510/5520, HP Spectre x360 13" ("Kaby Lake" version w/ Thunderbolt 3), Lenovo Yoga 720 13" & Yoga 920, Microsoft Surface Book 2.
Operating System & Platform Details (Windows)
Many current USB-C systems which do support Alt Mode video output do not support charging via USB-C. Systems such as this will output video from the dock, but will still need their proprietary OEM chargers. The Dell XPS 15 9550/9560 and Precision 5510/7510, for example, will display a warning during boot if connected to a 60W power adapter rather than a Dell 130W power adapter. These systems may still charge, but at a slower rate.
Conversely, while some USB-C phones and tablets may accept charging via PD, most do not support Alt Mode video output.
Thunderbolt 3 USB-C ports generally support Alt Mode output and DisplayLink functionality, but support for Power Delivery/charging on these ports is system-specific.
The UD-ULTC4K relies upon new functionality introduced with USB 3.1 Type-C and as such is not compatible with USB 3.0/2.0 Type-A legacy systems.
Most current phones and tablets with USB-C ports do not support Alternate Mode video output, and some do not support USB Power Delivery. Consult your device documentation or contact device manufacturer to confirm compatibility with these technologies.
Power and Charging
DisplayLink USB graphics technology works great for most workloads. However, gaming is not supported, nor is HDCP copy protected content playback (Blu-Ray, Netflix, Amazon Prime video, Hulu, etc). Does not support DisplayPort MST daisy-chain connections or conversion to Dual-Link DVI.
Conversion to HDMI, Single Link DVI, and VGA is possible using the following adapters (not included with dock):
To convert the DisplayPort output to HDMI 2.0: Plugable DP-HDMI Active Adapter
To convert the DisplayPort output to HDMI 1.4: Plugable DPM-HDMIF Passive Adapter(maximum resolution of 4K@30Hz refresh)
To convert the DisplayPort output to DVI: Plugable DPM-DVIF Passive Adapter
To convert the DisplayPort output to VGA: Plugable DPM-VGAF Passive Adapter
Plugable UD-ULTC4K docking station with stand, 1m USB-C to USB-C cable with eMarker, 100W (20V, 5A) power adapter (100V-240V) with a US power plug, quick start quide
