Come to think of it, there’s another bit of whitelist logic that seems odd to me. I’ve been playing some videos today that are 2160p/25fps. I’ve got 2160p/25Hz whitelisted. But the output mode defaults to 2160p/50Hz instead of 25. That wouldn’t be a problem except that the Vero 4K+ seems to have occasional issues with outputting 25fps at 50Hz - sometimes leads to jerky playback.
So, low priority, but maybe that could be tweaked too at some point? In general, if there’s a mode that exactly matches the video’s dimensions and frame rate, it doesn’t make sense to output at double the refresh rate; that should only be a fallback if there’s no exact match.
