Extended information:
The cable length limitation of HDMI is one of its main problems. In self-tests by some consumers, it was reported that the standard 28AWG specification HDMI copper cable is approximately more than 5 meters long. Signal attenuation begins. This length is usually not long enough to connect the projector to the computer.
The HDMI organization does not recognize this restriction. Its HDMI FAQ page states: "Developers have seen cables pass through a cable no shorter than ten meters without an "adapter". HDMI "Standard Cable" Commitment Test".
Increasing the diameter of the copper wire in the cable to reduce impedance is one of the ways to effectively extend the cable length. There are also reports that 24AWG cable performs better than 28AWG.
Currently, a single HDMI equalizer IC can increase the maximum length of 24AWG HDMI cable to 50 meters.
