      So I was playing kirby dream course on my SNES mini (RGB Modded with De-jitter) on my samsung 4KTV (UN506290), and while i tested before on super mario world with FireBrandX’s settings (in 5X) for an hour, it was just fine. But today with Kirby Dream Course, after 5-10mins, the ossc keeps losing sync and the image keeps dropping in and out. It happens on the HDMI switcher AND directly on all 3 HDMI ports of the TV.

      Is it because of the game itself and I need to change something?

        Could be similar to this issue:

          Okay so I tried increasing the Vthreshold from 123 to 191, sync didnt seem to drop out anymore. Also tried increasing it to 225, the game played just fine now after playing through for 20 minutes. Seems like it fixed the sync problem but Will keep an eye on it for now.

            I on my SNES with Final Fantasy mystic quest I get a split second drop out once every 3 hours or so, you think this setting could alliviate for that me as well?

              Id say give it a shot, play around with it to see whats works for you. It sounds to me after skimming through that thread is that it can be different cases for some of the SNES games.

                on Junker it says that it should be adjusted as last resort, what would the other options be to try first?
                also do any of these options add latency?

                  Good quality cables, dejitter board.

                  No OSSC options add latency.

                    uping my vth to 191 after about 2hrs 30 mins no drop out.
                    Not sure if it’s resolved.

                    But could having to up vth mean that my cable isn’t the greatest quality?

                      I’m using Csync cable from Retro Game Cables and have dejitter mod installed on 1Chip SNES. Was getting sync drops on 2 capcom games (Street Fighter Alpha 2 and Saturday Night Slam Masters) and increasing the Vthreshold was the only resort to stop the issue.
