PRO: projector below the screen
Choose the PRO orientation when the UST projector sits on furniture or another surface below the image. This is the conventional laser-TV layout and the optical screen structure must accept light arriving from below.
PRO A: projector above the screen
Choose PRO A when the UST projector is installed above the screen. The optical direction is reversed relative to a tabletop UST setup, so the screen material must be oriented for that light path.
Why ordering the wrong orientation is serious
A UST ALR surface is designed to reject light from unwanted directions. If the projector is placed where the screen expects ambient light, the screen can reject the projector's own light. This is why orientation should be confirmed before size, color or price.
What to photograph before you order
Take one straight-on photo of the planned screen wall and one side photo showing projector position. Measure the planned image width, projector height and distance from the screen. Those references make it much easier to verify the correct configuration with the merchant or installer.
