![]() ![]() That means installation is normally far easier. That allows you to have the projector in front of you and hence make better use of any onboard speaker system it might have while also keeping the noise from its cooling system as far away as possible.Īlso, a UST projector is typically meant to cast up from a surface, like a table or a media cabinet, whereas you typically want to mount a standard projector on the ceiling to get the best image with the least amount of keystone correction. With its 0.23:1 ratio, the Formovie THEATER can get an 80-inch image while placed just 14 centimeters away from the projection surface and a 150-inch one at 49 centimeters. Most traditional projectors tend to have a 2:1 throw ratio - you need to have the projector about 5 meters away from a surface to get a 100-inch image. You can use this nifty calculator to get a rough idea. ![]() With a traditional projector, you need a pretty big room to get a decent size image. This kind of setup is desirable for a number of reasons. Generally a projector needs to have a throw ratio of less than 0.4:1 to qualify as UST. This is achieved via ultra-wide lenses and light source and lens arrangement that can be quite challenging to pull off. What is an ultra-short-throw projector, and why would you want one?Īn ultra-short-throw projector or UST is one that needs very little space between it and the projection surface to cast a large format image. ![]()
