    It has been a month or two since I did this, but I don’t recall doing anything special on the OSSC.
    I have this setup:

    A CGA2RGB rev B01 and a OSSC is 1.6 with firmware 0.78.

    C-128 RGBI -> CGA2RGB -> VGA OSSC -> HDMI out to a DELL 2407WFP

    I have the jumper set to pins 2-3 (closest to the board edge).
    That will set the CGA2RGB to output separate sync RGBHV.

    I direct plugged the 128 to the CGA2RGB.
    I ran a VGA cable from that to the OSSC.
    The monitor is connected to the OSSC with a HDMI cable with a DVI-D adapter on the monitor.

    From what I recall, the OSSC autosensed the RGBHV signal and worked out of the box.
    I don’t think I set Line2x or 3x.

    Is there a 5V power supply properly connected to the CGA2RGB?

    If none of that helps, let me know and I’ll set it up again and list out any other settings.
