Below is what HDMI has to say about their new HDMI Cable Power standard. New powered HDMI cables will allow longer HDMI 2.1 cables to be created, allowing source devices to be placed further away from sync devices. These cables are designed to be as easy to use as passive cables (though powered-cables will be directional), and will support power though compatible HDMI connectors or using external power though Micro USB or USB Type-C. Presenting the new "HDMI cable power" standard, a new standard which will allow HDMI users to utilise longer cables using active electronics. Thankfully, those days may soon be behind us. Yes, many cables claim they support said data rates at longer cable lengths, but many of these cables exhibit stability issues when those claims are put to the test. If you require the high data rates of HDMI 2.0 or HDMI 2.1, it is hard to find a cable that actually works beyond a length of 3 meters. If there is one problem that the HDMI standard has, it's that it is a pain to purchase long cables. If you use passive cables, you should use the shortest length possible.HDMI's new cable power specification will enable the creation of longer high bandwidth cables
HDMI REVISIONS 1080P
Cables that are not certified for resolutions higher than 1080p may experience problems when the cable is longer than 25 feet, resulting in errors in the video and audio. HDMI extenders also perform an active conversion to standard category cable (for example, CAT5, CAT6) or to wireless.Ī passive cable does not convert any signals and is limited to a maximum length of 50 feet (15.2 meters). The cable converts the signal at the source to one that is better suited for the longer distance, and then converts the signal back to standard HDMI on the display end of the cable. carries active cables up to 100 feet (30 meters). Active cables require power from either the HDMI port or an external power source. HDMI cable types can be separated into two different categories: active and passive.Īn active cable is designed to exceed the maximum length of a standard passive cable.
HDMI REVISIONS PC
Greater support for PC sources, One Bit Audio.The following table gives a brief overview of the progression of HDMI. Cables with Ethernet can still be used with any earlier versions of HDMI. Cables that are certified for version 1.4 and later can contain Ethernet and will usually state "with Ethernet" in the description. Using cabling that is certified with a specific version number becomes more important when you use the latest standards in your setup, due to increased bandwidth requirements. For example, if you have a 1.2 source and a 1.1 display, the 1.1 capabilities will be used. The performance of the system is defined by the earliest version of HDMI used in the setup. HDMI has been designed to be fully backward compatible with older standards. Numerous revisions have been made to the HDMI standard, which have increased the capabilities while maintaining the same connectivity. HDMI can be passively adapted to DVI and DVI can be passively adapted to HDMI, but there is no official support for audio in the DVI standard. HDMI connector types include the following: For computers, it can replace VGA and the video from HDMI works with DVI. HDMI replaces analog consumer video standards, such as composite, S-Video, and component, as the first digital consumer video standard. HDMI is a modern digital audio/video standard used on many computers and television displays.
