    Appears to be just labeled SYNC, which I am assuming is H+V. Am I wrong?
    That is TTL-level composite sync. I don’t recommend wiring it to LM1881 since the chip is meant for extracting sync from video-level composite/luma signal – you might otherwise run into issues. It should be possible to wire that SYNC directly to VGA H-pin to be used with OSSC AV3 RGBS.

    I am having the exact same issue.
    It’s not picking up the synch of any of the SCART connections I have in AV1.
    Please make a separate topic since your issue is not related to using VGA/AV3.
