Choose fixed frame when the wall is dedicated
If the projector is your main display and you do not need artwork or a television on the same wall, a fixed frame is hard to beat for simplicity.
Choose floor rising when the room is shared
A retractable screen can preserve the room visually and may pair well with cabinetry. Just remember that UST projection is unforgiving of surface waves, so tensioning quality matters.
