    Okay so I’ve been trying to get this working now for.more than a week. At this point I don’t know if it is my tv or the OSSC.

    The OSSC is connected to a HDMI matrix switcher. Other display stay on just my tv loses signal for a second.

    I have tried changing HDMI cables. I’m testing this on a PS2 (scph-50004) 480i/576i signal with RGC scart sync on luma and csync cables.

    The OSSC doesn’t lose sync (no red led) other displays keep working fine.
    My tv is a sony kd55xd8505.
    The switcher is an ACT 7860
    Otaku scart auto switcher
    Any idea if I can try something that I haven’t tried yet?

    What I’ve tried:
    Changed OSSC to DVI mode
    Different HDMI and scart cables
    Reset all settings on ossc
    Set TV to game mode
    Upsample 2x enabled and disabled
    480p in sampler on DTV and VESA
    Changed EDID settings in the HDMI matrix switcher

    Any help or tips would be appreciated.


    Have you tried to increas Analog sync Vth?

    Sync Opt. -> Analog sync Vth


    Would it matter if I set this to the max 349mv?

    I have increased it now and will be testing for a bit to see if it drops out again.
