    Hi Esin,

    What is LCM?

    Are you supposed to use two displays LVDS 1-port and LVDS 2-port as in the table you shared? Note that 947 can act as a 1:2 repeater, meaning it can push the same video to two deserializers, not possible if the two displays have different clock frequencies.

    Best,
