echogear short 2ft hdmi ultra hd high speed cable - 4k & hdr compatible - meets latest hdmi standard - gold plated connections - supports hd, 4k ethernet signals 120fps refresh & 48gbps bandwidthFuture-proof your TV setup and get the most out of your gaming equipment by upgrading to an Echogear HDMI 2.1 4k compatible cable. It's backward compatible to work with your existing gear and won't be outdated for years, saving you money. This cable meets the latest HDMI standard, which gives you:More BandwidthThink of HDMI bandwidth as how much information can be transmitted at one time. This cable has 2.6x greater bandwidth than older cables. 48Gbps (vs 18Gbps) is a crazy amount of bandwidth that will be able to support resolutions up to 10k. That's right, 4k signals are a piece of cake for this cable. Upgrading HDMI cables is like replacing a 2 lane dirt road with a speedy 5 lane highway, so tell your data the commute is about to get easier.Faster Refresh RateTraditional HDMI cables can support 4k content, but only up to 60fps. As computers and gaming systems continue to become more robust, so do the hardware requirements. The best gaming system in the world won't be able to realize it's full potential without an upgraded cable. Always remember, your hardware is only as good as the cable that connects it together.Dynamic HDRYou've probably heard of HDR (High Dynamic Range) on newer TVs, and quite frankly it's awesome. While 4k gets a lot of hype, HDR is the best improvement in TV picture since HD became a thing. The next evolution is Dynamic HDR which allows each scene to maximize HDR's capabilities, instead of a single setting for the entire movie. That means contrast on all scenes will be perfect. Just remember, your hardware has to be capable of using Dynamic HDR for this cable to transmit the signal.Overall, if you are buying a new HDMI cable, getting an upgraded cable is the best bet. While your Roku, Blu Ray Play, or PlayStation Plus might not be able to take advantage of the awesome specs today, you'll be glad you have the best cable when new technologies come out.
