The Radeon R9 Fury X shipped without HDMI 2.0 support, so AMD's top-end card couldn't drive many 4K TVs and monitors at 60Hz with an HDMI cable. Fortunately, that shortcoming can be corrected with an active adapter that converts a DisplayPort 1.2 port to HDMI 2.0. Club 3D has announced a pair of these handy adapters, one for mini DisplayPorts and one for standard-sized versions.
Unlike the bad old days (or even today, if you're Apple), Club 3D's active DisplayPort adapters don't need a separate connector or spare USB port for their power needs. The company claims its adapters are fully compliant with the HDMI 2.0 standard. Along with a 4K, 60-Hz video stream, these adapters can support up to eight channels of audio.
Club 3D hasn't announced pricing on these adapters yet. Active adapters from other manufacturers can be had for under 20 bucks on Newegg, but all of those are limited to 30Hz for 4K video streams.
