HDMI Q & A
What is the difference between a “Standard” HDMI 
cable and a “High-Speed” HDMI cable?
Recently, HDMI Licensing, LLC announced that cables would be 
tested as Standard or High-Speed cables.
4 Standard (or “category 1”) HDMI cables have been tested to perform at speeds of 75Mhz or up to 2.25Gbps, which is the 
equivalent of a 720p/1080i signal.
4 High Speed (or “category 2”) HDMI cables have been tested to perform at speeds of 340Mhz or up to 10.2Gbps, which 
is the highest bandwidth currently available over an HDMI 
cable and can successfully handle 1080p signals including 
those at increased color depths and/or increased refresh 
rates from the Source. High-Speed cables are also able to 
accommodate higher resolution displays, such as WQXGA 
cinema monitors (resolution of 2560 x 1600).
How do I run HDMI cables longer than 10 meters?
4
 There are many HDMI Adopters working on HDMI solutions that extend a cable’s effective distance from the typical 
10 meter range to much longer lengths. These companies 
manufacture a variety of solutions that include active cables 
(active electronics built into cables that boost and extend the 
cable’s signal), repeaters, amplifiers as well as CAT5/6 and 
fiber solutions.
How can I tell if a cable is an HDMI certified cable?
4
 All HDMI products are required to be certified by the manufacturer as part of the HDMI Compliance Test 
Specification. However, there may be instances where cables 
bearing the HDMI logo are available but have not been 
properly tested. HDMI Licensing, LLC actively investigates 
these instances to ensure that the HDMI trademark is 
properly used in the market. We recommend that consumers 
buy their cables from a reputable source and a company that 
is trusted.
