1.1 Questions about HDMI products
Q: What does the HDMI version mean?
A: In the past the HDMI version number (for instance 1.3b or 1.4a) was used to mark cable products. This is not allowed any more because often suppliers marked products with wrong HDMI versions. The result was that customers often bought products in the believe that certain HDMI features are supported which was not always the case.

HDMI cables are only produced according to the following 4 HDMI cable specifications:

  • • HDMI
  • • Highspeed HDMI
  • • HDMI with Ethernet
  • • Highspeed HDMI with Ethernet
Please note that the a.m. HDMI cable specifications do not guarantee that a specific HDMI version is supported by every HDMI cable supplier/ trader. With KabelDirekt HDMI cables you are on the safe side that always the newest HDMI version is supported.
