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.
