    does anyone know if it’s possible to use 1 (preferably 2) LG 4K displays connected via thunderbolt 3 dock? So that way you only have one cable running to a 2016/17 MacBook Pro?

    If you meant the Ultrafine 4K's Apple are selling, then yes for 1, no for 2.

    The best current dock on the market, the CalDigit "TS3 Plus" dock, has a TB3 out and 2x USB-C's (1x 5Gb/s, 1x 10Gb/s) but they don't support display output from the USB-C's, unfortunately. So you can only connect 1 of those displays to the TB3 port (that obviously takes vanilla non-TB3 USB-C connected displays). Also, you can't connect displays using the USB-C output via any adapter into the docks' DP port, either.

    If you meant other non-USB-C LG 4K displays, that have say DP/mDP/HDMI outputs on them, then yes for 2:
    1 via the DP port on that dock (with a DP-to-mDP/HDMI adapter, as required), and 1 via the TB3 output port (using a USB-C-to-DP/mDP/HDMI adapter, as required).
