Long Throw vs Short Throw vs UST Projector Screens
The most expensive screen mistake is buying an ALR surface designed for the wrong projector geometry.
| Projector type | Typical placement | Screen concern |
|---|---|---|
| Standard / long throw | Several feet/meters from screen, often ceiling mounted | Use ALR material engineered for conventional front projection |
| Short throw | Closer to screen | Check exact screen compatibility; geometry sits between categories |
| UST | Very close, normally below screen | Use UST-specific ALR/CLR material that handles steep upward light |
Why UST ALR is different
A UST projector throws light upward at a steep angle from a console very close to the wall. Its screen structure is designed around that geometry. A standard projector sends light from much farther away and closer to perpendicular. Mixing those systems can cause severe brightness and uniformity problems.
What “standard / long throw compatible” tells you
It means the material's optical behavior is intended for conventional projector placement. The featured NothingProjector screen is specifically labeled for standard and long-throw projectors and should not be treated as a UST screen merely because both products use the ALR label.
Short throw needs extra checking
“Short throw” covers a range of throw ratios and installation geometries. Do not assume a long-throw or UST-specific ALR screen will be ideal. Check the screen maker's compatibility information for your exact projector setup.
Using a conventional standard or long-throw projector?
The featured NothingProjector product is made for that category and is offered in large fixed-frame sizes.
