    Hey guys,

    what's the best/cheapest way to split a HDCP 2.2 4k 60hz signal and then convert one of the outputs to 1080p HDCP 1.4 so I can feed a HDFury X4 with it?
    Split it with this splitter https://www.amazon.com/gp/product/B079HJWF31/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 and then convert the signal with https://www.amazon.de/LINDY-BIDIREKTIONALER-HDMI-KONVERTER-38166/dp/B078ZCVGMY ? (I am german so german amazon here for this one)

    Thanks in advance. I hope you guys were facing the same problem and found out a cheap way to solve it. Maybe even a one-device-solution?

    Edit:
    The Gofanco splitter can already output in 1080p on one of the out-ports. So i guess a HDCP konverter that can only do YUV 4:2:0 in 4k 60hz will be able to do 1080p in YUV 4:4:4, right?

    Edit 2:
    OMG I just realized that HDMI 2.0 can only do YUV 4:2:0 in 10 bit HDR at 4k 60hz because max bandwidth is 28Gbps .. So actually all devices that support 18Gbps (or 4k/60hz 4:4:4 (8-bit) or 4:2:0 (10 bit)) are okay because there's nothing that could do it better before HDMI 2.1?
