HDMI cables are of two types: with support for high resolution, and also with support for HDTV resolution. Also it is necessary to touch on the topic of the length of the wires and to consider in advance that the length can vary from 1 to 10 meters; but do not forget that the longer the cable, the greater the likelihood that there will be a signal loss.In this regard, some manufacturers have emerged that offer so-called "active" HDMI cables with various technologies that can be used to transmit data over very long distances. When you buy a cable, be sure to turn its on the wire, as well as on its connectors.
