OWC USB-C Dual HDMI Adapter DisplayLink 4K 60Hz

SKU CH-DTT2-RYX74

Adds two 4K 60 Hz HDMI displays to a single USB-C or Thunderbolt port on M1 Macs and PCs, bus-powered via a 13-inch cable

  • Changer TypeUSB to HDMI
  • Add two 4K displays at 60Hz from one port
  • Overcomes M1 Mac single-display limit with DisplayLink
  • Choose extended or mirrored desktop modes
  • Bus-powered through 13-inch integrated USB-C cable
  • Compact size similar to a smartphone for travel

Solves the M1 single-display limit

The OWC USB-C Dual HDMI Adapter uses DisplayLink technology to drive two 4K monitors at 60 Hz from a single Thunderbolt or USB-C port. It is built for MacBook Air, MacBook Pro 13", Mac mini and 24" iMac models based on Apple M1 silicon that natively support only one external display. Windows and ChromeOS laptops with limited video outputs also benefit. The adapter is bus-powered through its integrated 13-inch USB-C cable.

Replaces a tangle of single-port dongles

Instead of chaining multiple adapters and cables to reach two screens, this one unit delivers dual 3840 x 2160 output at 60 Hz. The jump is worth it when you need Extended or Mirror modes on an M1 Mac without buying a dock or a Thunderbolt hub. It also suits any USB-C laptop that lacks native multi-stream transport support for dual 4K. No external power supply is required.

Plug in, install driver, connect monitors

Setup requires installing the DisplayLink driver on macOS and Windows before the displays appear. The 13-inch tethered cable keeps the adapter close to the port and reduces strain. Common issues are forgetting the driver install, using a charge-only USB-C cable on the host side, or expecting more than two displays. The compact, smartphone-sized housing travels easily in a laptop sleeve.
