Features

USB-C to HDMI Adapter Connects Three 4K HDMI Displays to Your USB-C Device
This USB adapter connects three independent HDMI monitors, projectors and/or televisions to the USB-C or Thunderbolt 3 port on your MacBook Pro, Chromebook or Windows laptop. It’s an ideal connector for creating video walls, giving video presentations in conference rooms and classrooms, editing multiple documents on a larger screen, or streaming video for digital signage in crystal-clear 4K.

Supports USB-C DisplayPort Alternate Mode for Converting Audio/Video Signals
By connecting the built-in USB-C cable to a source device that supports USB DisplayPort Alt Mode, you can output 4K video and digital audio to HDMI monitors, televisions or projectors without installing special software drivers. Note: To achieve 4K resolution, the source device should support DP 1.4 Alt Mode. When a monitor is connected to a DP 1.2 Alt Mode source, the corresponding resolution will be decreased due to bandwidth limitation. When using a Windows OS source, the maximum triple output is x1 4K/60 Hz and x2 4K/30 Hz outputs. When using a macOS source, the maximum triple output is x3 4K/60 Hz outputs.

DisplayPort SST and MST Modes Allow Connection of Multiple Displays
By connecting the USB-C adapter to a source that supports DisplayPort Single-Stream Transport (SST) or Multi-Stream Transport (MST) mode, you may connect up to three displays simultaneously. This allows you to display the same image 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.

Enjoy the Clarity of True 4K Video with HDR, 4:4:4 Color and 7.1-Channel Audio
This USB to HDMI adapter supports Ultra HD video resolutions up to 3840 x 2160 (4K x 2K) at 60 Hz with 7.1-channel surround sound. High Dynamic Range (HDR) provides a wide range of vibrant colors with richer contrast, brighter whites and deeper blacks that pop on your 4K display. HDCP 2.2 compliance allows you to stream 4K Amazon and Netflix content with no complications. This adapter also supports 4:4:4 chroma subsampling for top-level PC gaming or using your HDTV as a PC monitor.

Ready to Use Right from the Package, So You Can Plug and Play Immediately
The adapter requires no software or external power. Just connect the USB-C cable to the USB-C or Thunderbolt 3 port on a source device that supports USB DisplayPort Alternate Mode, and connect the HDMI ports to your displays with user-provided cables (such as Tripp Lite’s P568-XXX-2A Series cables). 

Typical Applications

  • Watch 4K video content from a Blu-ray player, game console, laptop or tablet on three 4K televisions or projectors
  • Connect a Chromebook or MacBook to a conference table’s A/V box to give a video presentation on large screens
  • Attach three 4K monitors to your PC to allow easier multitasking
  • Send Ultra HD content to digital signs or point-of-sale displays
