HDMI
TM
 Q & A 
Q. What is the difference between a “Standard” HDMI
TM
 cable and a “High-Speed” 
HDMI
TM
 cable? 
Recently, HDMI
TM
 Licensing, LLC announced that cables would be tested as Standard or 
High-Speed cables.  
․
Standard (or “category 1”) HDMI
TM
 cables have been tested to perform at speeds of 75Mhz 
or up to 2.25Gbps, which is the equivalent of a 720p/1080i signal.  
․
High Speed (or “category 2”) HDMI
TM
 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
TM
 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). 
 
Q. How do I run HDMI
TM
 cables longer than 10 meters? 
There are many HDMI
TM
 Adopters working on HDMI
TM
 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. 
 
Q. How can I tell if a cable is an HDMI
TM
 certified cable? 
All HDMI
TM
 products are required to be certified by the manufacturer as part of the HDMI
TM
 
Compliance Test Specification. However, there may be instances where cables bearing the 
HDMI
TM
 logo are available but have not been properly tested. HDMI
TM
 Licensing, LLC actively 
investigates these instances to ensure that the HDMI
TM
 trademark is properly used in the 
market. We recommend that consumers buy their cables from a reputable source and a 
company that is trusted.
