A:Answer Yes. These ALR screens are explicitly designed for Ultra Short Throw (UST) projectors (I think all of them are laser). The face of the screen is like a saw tooth:

The slanted part is white, the flat part is black. That way the light coming up from the bottom (at a very steep angle) reflecting it toward the viewer. The light from above hits the flat black part of the screen, which absorbs a significant amount of that light (usually 80-95% of the ambient light), which dramatically affects the amount of "wash out" of colors the ambient light causes.
This even helps with light coming directly from the side. The "horizontal" light hits the white part and is reflected down onto the black surface before being reflected back up onto the white part. This does reduce the effectiveness slightly, but it is still 70-85% effective.
You can see this in action by looking at an ALR screen. From above, the screen appears to be a dark gray, from straight on, a middle gray, and from below, it looks like a light gray.
Regardless, almost any UST-designed ALR screen will provide a dramatic improvement over a flat, white, non-ALR screen.
There are ALR screens that are designed for long-throw projectors, but this one is designed for UST projectors.
Hope this helps!
