Reply To: SNES video/audio randomly cuts out in HDMI mode but not DVI

[euan]

To update here, in case anyone else runs into this:

I was able to mostly solve this by increasing Sync Vth to 236. That’s the biggest number before the image starts to be affected in my setup. I’ve still seen a couple of instances of losing sync since then (OSSC light goes red) but it’s been significantly reduced.

From googling around more, I stumbled onto threads like this one: https://videogameperfection.com/forums/topic/black-screen-in-yoshis-island-snes/ and https://videogameperfection.com/forums/topic/snes-ossc-fw-0-83-de-jitter-mod-sync-keeps-dropping/. I didn’t realize that the game would make a difference, so it turns out I’d changed more variables than I thought :). The DVI/HDMI thing was a red herring: the sync drops only seem to happen during the battle screens of Final Fantasy 2/4 and 3/6 for me — other games are fine. I’m back using HDMI and things are mostly fixed.
