    They definitely can be directional if there is signal conditioning circuitry in one of the ends. No harm trying it out as is though.


    For ?

    I don't doubt you btw just interested

    I've ARC and Ethernet on a 5 euro HDMI lead

    Just wondering what else this would be for or what the op would need it for ?

    For example if it was necessary, he might not have the hardware that requires it.

    As you say worth a shot trying it.

    Depending on the length or quality of the cable the signal at the far end can be degraded so badly that the receiving equipment can't make sense of it. Active cables have signal conditioning chips in one end which are calibrated to the characterstics of the cable at manufacture and undo the degredation. Cheaper to only have these in one end of the cable rather than both, hence directional.

    Waste of money for short runs IMO but makes sense in longer runs.

    Directional cables usually have an inbuilt booster for the longer runs , they look like bog standard hdmi cables that he has used there ?

    Now the electrician may have used to shorter lengths and installed a booster , but would be very silly if he did that.

    I’m import these cables and only get them with the active chip over 20 mtrs
