the resolution changes to 525i and the signal drops

When you say the signal drops, does it drop on the OSSC (the LCD display shows no sync or some garbage value) or only on your display?

I’m not sure if that will solve the blanking issue as that could be the monitor not fully tolerating the Amiga’s clock or various other reasons but, certainly worth a try.

Make sure you have your GPU settings set to scale on the display, not on the GPU

Disable GPU scaling entirely, you want the raw resolution to be passed through, as much as you can anyway.

Well, I’m using a CRT TV, 480i is all there is. If you mean the signal I’m feeding into the OSSC Pro then yes, that’s progressive.

You can do this using the OLED display on the OSSC Pro itself, expansion opt->Extra AV Out mode->RGBCS/RGBS
