For quite some time HDMI cables were sold with version numbering such as "HDMI 1.3, HDMI 1.4", etc. That led to confusion for consumers, because nobody could say what the difference in these HDMI cables actually was. Since 2010 the HDMI Licensing Organisation claims that HDMI cables are only to be sold being called either HDMI Standard or HDMI High-Speed (each with or without ethernet channel).
Thanks dui attorney free consultation to his decision, finally the version numberings have disappeared. Today, every HDMI cable branded with the "High Speed HDMI" Logo is able to transmit the required transmission rate of 10.2 Gpbs (which is enough bandwidth for new extra functionalities such as Deep Color, 3D, HD-Audio or the "HD successor" 4K) Tip: Check if the functionality that you need in particular is explicitly listed on the HDMI cable product description.
Tip: HDMI High speed cables are often cheaper than Standard cables because they are produced in a much larger scale. It's worth taking them!
Difference 3: Manufacturing Quality
There are differences in HDMI cables, of course, concerning the manufacturing / build quality. Especially the connection between the connector and the cable harness is a weak spot for most cheap cables. At this intersection cheap cables would often break when they are bend to much or too often.
Also the shielding plays an important role. HDMI cables with bad shielding are vulnerable to signal interferences caused by electricity for example. In the worst case this will cause errors in the audio and/or video data stream.
Normally, two up to four times shielded HDMI cables with a good build quality are good enough for consumers. Take care that cables provide extra shielding when they are installed in close proximity to electricity cables.
Difference 4: HDMI Cable Length
HDMI Highspeed cables that come in the standard length of 1m - 3m dui attorney free consultation are mass production and therefore very affordable. From 5m and more cable become much more expensive normally, because the demand for the material and manufacturing quality is higher. In contrast to for example fibre optic cables HDMI cables work with copper wires that cause higher resistance depending on their length.
Therefore check the needed length before buying HDMI cables. By choosing an HDMI cable with the exact length you will both save money and minimize the risk of signal errors.
