Output full and advanced

[grain]

Hello, here i am, a newbie...
I have an issue with resolute arena 5 on my MBP 17":
i'm trying to map a solid with a projector so, i followed some tutorials on YT but here with the problem:
I open the fullscreen output on the projector (display2) and it works... but When i try to open advanced in order to modify proportions and adapt the projection to the solid, the full screen output disappear and i only see my desktop wallpaper

Am I mistaking something?

Hi. When you opens advanced output, you see list of screens/slices/masks on the left of window. Select first screen, and in properties (right part of window) select your display.
