The Club 3D CAC-1335 is the perfect solution to connect to any DisplayPort™ 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 DisplayPort™ 8K30Hz or 4K120Hz specifications, the Club3D CAC-1335 will be the simple way to connect your HDMI™ source device to your new 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.
