So… Get this. I hooked up a different display just for the heck of it (1080p) and they showed up on the directly connected screen. Both on the main screen playing (top icons) and in “screensaver mode”. The original display was an 8" 1280x720. Using the same HDMI connection for both.
Perhaps it was having trouble with the resolution? In the browser I’m just seeing the wallpaper, but on the attached screen it seems to be behaving properly.
