    I am trying to earn a legranda hdmi socket (Catalog number: VALENA-HDMI), I unplugged the hdmi cable and connect it according to the diagram in the manual, after connecting all the wires, the image is not displayed, the Gembird cable tester (NCT-4) displays the error "cross (crossover or cross- talk interference) "and I'm not sure what it means?

    Cross-over means crossed wires.

    For example -

    The wire X is attached to pin 2 plug A, and on plug B to pin3.
    Y - pin 3 cable plug A, pin2 plug B.

    With the help of Google, your friend will find a lot of information on this topic.

    These are interference -> crosstalk - the most common reason is inadequate shielding.

    Is there anyone who has managed to earn hdmi on such a socket? I already try the second hdmi cable and each manufacturer uses the colors as they like, which means that reaching the correct solution seems impossible.

    There are 3 to be attached but the colors do not match.

    Attach the others freely, but equally at both ends.

    Insert the plug of the processed cable into the same socket and check with an ohmmeter how the colors of the wires are distributed (on one probe, the wire on the other, the terminal in the socket).
