An HDMI cable is rated by its speed which equates to the amount of data it can transfer in a given time. Ratings are High Speed, High Speed with Ethernet and Standard Speed. Contrary to that which some would like you to believe, there is no picture or sound differnce between HDMI cables, they either work or they don't and the amount of money you spend on a cable is in no way related to the quality of image or sound you will get.
Another myth is that HDMI cables are rated by specification number, this has not been the case for a long time, there is no such thing as an HDMI 1.4 cable, or an HDMI 2.0 cable, they do not exist, they are purely misleading marketing terms. The correct term for HDMI 1.4 cables or HDMI 2.0 cables, is High Speed with Ethernet or High Speed, HDMI 1.4 and HDMI 2.0 is an equipment specification only.
We have a range of HDMI cables to suit all needs, an active HDMI cable is best used for long cable runs of 20m to 50m, these are a directional cable which have a built in boosting electronics.
