Will a grey screen noticeably boost contrast or black level, perhaps at the expense of brightness? Are there any ultra short throw projectors that are low latency, 3D enabled, or both?
I haven’t seemed to be able to find much on ultra short throw projectors, I assume they’re a bit more pricey than traditional ones, and I know the screens are expensive.
An UST projector plus an grey screen will not give any improvements over a regular throw projector with a grey screen.
An UST projector plus an UST ALR screen is unnecessarily expensive. The same effect can be achieved with a regular throw projector and regular ALR screen.
While UST ALR types of screen have a different angle at which it reflects light, it's still a screen and when viewing with lights on will have it's image washed out if the lights are not placed adequately. The most affected parts with be the dark parts of the image. How much depends on how much light is bouncing around the room.
It doesn't matter with what type of screen.
Depending on the projector, it's light output, distance from screen, image projected, material of the screen, ALR fabrics can have visual artifacts, such as hotspots, sparkle, narrow viewing angles. More expensive screens tend to have less artifacts.
The decision to go with an ALR screen depends on how much time will be spent with lights on, and the intensity of the lights. But, seeing that 3 out of the 4 modes of use in your first post are movies, I assume lights off viewing, the need for an ALR screen would be reduced. Personally I would not use an ALR screen for movie/TV watching with lights on, unless you have people over and/or it's a very bright broadcast, like a football game or a talk show in a brightly lit studio.
There is a link in a post above discussing the need for an ALR screen.
