CableCreation USB-C to Dual HDMI Adapter Aluminum Gray

SKU CH-KEY8-WRAH9

Connects a Thunderbolt 3 or DP ALT mode laptop to two HDMI displays at up to 4K 30 Hz with plug-and-play simplicity

  • Dual 4K monitors at 30 Hz for expanded workspace
  • Thunderbolt 3 and DP Alt Mode host support required
  • Driver-free plug-and-play setup on Windows and macOS
  • Extend or mirror modes on Windows, mirror only on Mac
  • Aluminum gray housing for heat dissipation and durability

USB-C Dual HDMI Adapter

The CableCreation adapter converts a single USB-C port into two HDMI outputs for users who need dual external displays from a laptop or desktop. It supports mirror and extend modes on Windows and mirror mode on macOS when two displays are connected.

Compatibility Check

Verify that the host device provides Thunderbolt 3 or DisplayPort Alt Mode video output through its USB-C port before ordering. The adapter will not function on ports that carry only data or power without video signalling.

4K 30 Hz Output

Each connected monitor can run at up to 4K resolution at 30 Hz when used with an HDMI 1.4 or higher cable. The plug-and-play design requires no driver installation, and macOS users must select mirror mode in System Preferences when both displays are active.

Questions about this item

What comes in the box and do I need to buy any cables separately?

The adapter is the only item supplied. You must provide your own HDMI cables — at least HDMI 1.4 rated — to reach 4K@30Hz on each display.

Which version of this adapter should I choose for a MacBook Pro from 2017, 2018 or 2019?

There is a single model listed. It works with MacBook Pro 2017, 2018 and 2019 provided the USB-C port supports Thunderbolt 3 or DP Alt Mode.

What does the 4K@30Hz figure mean when I connect two monitors to a Windows laptop?

Each external monitor can run up to 4K@30Hz simultaneously in extend or mirror mode; the host resolution must be set to the same or lower value to avoid flicker.
