EDP Lane?

I'm planning out a 3 screen 4k monitor laptop build but, I'm unsure of of how many pins on the EDP connector my LCD should have; should it be a 2-lane edp connector with 30 pins or a 4-lane EDP connector with 40 pins? I've looked on the on the block diagram and it says that its a 41 pin? Thanks in advance!

    Yes, we chose a 41-pin connector. We will release pin definition once UP Squared comes to mass production. You may need to have a custom eDP cable for it. We are considering to sell eDP cable at UP SHOP as well. :-)

    Please sell that item on the shop. Any user who is planning to incorporate a screen into their build would greatly appreciate knowing that they're working with the correct hardware.

    i think what you actually meant is a 41 pin LVDS, not EDP. WOuld it be possible to carry so type of converter for
    EDP 4-lane(40 pin) and 2 lane EDP 2-lane(30 pin) to LVDS 41 pin. That would be most convenient as many of the higher resolution 4k lcd panels I was able to source have a EDP 4-lane interface.

    No, my understanding is Apollo Lake has a native eDP interface and they are bringing that out to the 41 pin connector, not LVDS (LVDS would require additional hardware). Though I can't find any info as to how many lanes the eDP interface on the Apollo Lake has.

    EDIT: I am thinking it is a dual lane interface since some Apollo lake SBC's I have seen feature "eDP/24-bit dual channel LVDS".

    I hope below information will be helpful.
    Please find here for block diagram. HDMI, DP and eDP are all directly from SoC.
