HDMI - HDMI cable?
Recently, HDMI Licensing Administrator, Inc. announced that cables would be tested as Standard or High-
Speed cables.
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.
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).
Q. How do I run HDMI cables longer than 10 meters?
There are many HDMI Adopters working on HDMI
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
amplifiers as well as CAT5/6 and fiber solutions.
Q. How can I tell if a cable is an HDMI certified cable?
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 Administrator, Inc. 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.
