For this alternative application, care is required to ensure no overhead ambient light is present during viewing, as the screen can't distinguish between that and the intended projection light.) (I have also heard of installations where a UST projector has been ceiling mounted and the screen flipped to allow the image to be correctly steered at the viewing position. With a UST projector resting on a counter, light rises vertically toward the screen at a steeply pronounced angle, but should ideally be sharply re-directed to the viewing position and not incidentally shower the ceiling. But, that's not what you want for a UST projector/screen combination. However, there are different types of screens to manage each application.Ī classic long-throw, ceiling-mounted projector relies on the screen to reflect light at an incident angle, much like the way a billiard ball banks off a table bumper in a direction opposite the angle of approach. Ultra short throw doesn't necessarily present intrinsic issues with ambient light compared to a machine parked across the room-both fall prey to any stray lumens coming from a source other than the projector. As with any two-piece projection arrangement, contending with ambient light is paramount, but especially so if you intend to use said projector as a replacement for your day-to-day TV. This is where ambient-light rejecting (ALR) UST screens come in. Merely add a screen of 100- or 120-inches diagonal to these models, and you're good to go.

Hisense, with its Laser TV series, has led the home UST charge, but LG recently joined the fray, and Optoma, ViewSonic, and start-up VAVA are all slated to release their own 4K UST entertainment centers this year that include on-board audio and internet streaming. Here in the U.S., the most popular application for UST projectors these days is classroom and institutional use, though a number of 4K models geared specifically for the home theater segment have reached market or are expected to this year.
UST projectors gained prominence as a consumer category nearly a dozen years ago almost exclusively in the Pacific Rim, where space limitations make traditional home theater projection a challenge.

But the company believes in sharing the wealth inter-divisionally, which has enabled their serriform optical filter surface lens microstructure technology to find its way down into the Aeon CLR (Ceiling Light Rejecting) series of screens designed for the growing segment of ultra short throw (UST) projectors. On the other hand, Elite ProAV, their companion division for the commercial market, focuses on leading-edge engineering that's less tethered to cost constraints. Garden Grove, CA-based Elite Screens maintains a presence in the global projection screen market with product design targeting cinema-quality performance at enthusiast-friendly pricing.
