Fokky

HDMI switching and audio extraction

What they actually do

The small boxes that reconcile a modern source with an older display, or several sources with one input.

Where these devices actually fail

EDID handling and HDCP negotiation, not bandwidth. If a picture works alone and fails through a switch, the cable is almost never the problem.

    • Works in both directions, so one box covers two opposite problems
    • No power supply, no driver, nothing to configure
    • A stated 3.4 Gbit/s is well below the 18 Gbit/s that full 4K 60 Hz normally implies

    Best for: Two sources into one screen, where the sources are 1080p or undemanding 4K.

    EAN
    6974426753397
    • Both cables supplied, which is unusual and removes two separate purchases
    • A volume control on the unit, so the level can be matched to the amplifier
    • Format handling is not stated, and a converter that accepts PCM only is silent on a Dolby Digital source

    Best for: A television with no analogue output feeding an amplifier that has no digital input.
