The Club 3D CAC-1336 is the perfect solution to connect to any USB Type-C 8K30Hz or 4K120Hz ready displays from a HDMI™ source which does supports these resolutions/specifications. If you have a PC or any other device that lacks the new USB Type-C 8K30Hz or 4K120Hz specifications, the Club3D CAC-1336 will be the simple way to connect your HDMI™ source device to your new USB Type-C 4K120Hz or 8K30Hz display(provided your source supports these resolutions). The Adapter is powered thru a Micro USB port(5V/1.5A). An USB Type-A to Micro USB M/M 1m / 3.28 ft is supplied in the box. Note: This adapter will only work on USB Type-C Displays that are self powered ! Please use one of our Club 3D certified Extension/Adapter cables to connect to your devices. For optimal usages of this adapter we highly recommend you to use the CAC-1576 or CAC-1571.
