![]() ![]() There are even interactive UST projectors that add sensors, so you can draw on the image and give commands the same way TV networks use displays on election nights to show information. Mount a UST projector just above a screen, and you can get close enough to the image to point to text or graphics you want to draw attention to without casting a shadow, much as you would with a whiteboard. ![]() Note that UST models can also be useful in business and education. But if you want a projector to use as a 100-inch-or-larger TV at home, and you don't want to deal with mounting it on the ceiling or running cables through walls, a UST is what you want. Ultra short throw (UST) lensing systems (which usually mix a mirror in with the optical elements) are even more expensive than short throw lenses. Then, we'll cover the key differences between these two categories, along with the factors you need to consider when choosing a short throw or UST projector. In this guide, we'll suggest our favorite short throw and ultra short throw (UST) picks for specific applications, choosing among models we've tested. Get one with an ultra short throw, put it on top of the entertainment center where your TV's sitting now, and mount the screen on the wall just above it. You want to replace your TV with a projector, but don't want to run cables through walls and ceilings to hide them? No problem. You want a big image in small room, but can't position the projector you have far enough back to get one? Well, you need a projector with a shorter throw. Throws, and the lenses that determine the throw, are classified as long, standard, short, or ultra short.ĭifferences in throw can give otherwise identical projectors very different capabilities. A projector's throw-the distance between it and the screen-is one of its key features and an important way to categorize it. If you hear "throw" and the first thing you think of is a ballplayer, you probably don't spend a lot of time with projectors.
