Those then pass through LCD displays containing the image and converge via another prism before passing through the projector’s lens.Įpson is the primary user of LCD tech, along with Sony, Sanyo and others. LCD tech, meanwhile, uses a prism to split a light source into red, green and blue beams. The biggest drawback is the rainbow effect, or bright red/blue/green artifacts that affect some viewers more than others. The benefits of the tech are portability, high contrast, less fringing and cheaper projectors, especially 4K and ultra-short-throw models. Both use mirrors that tilt by +12 and -12 degrees for white and black, but TI recently unveiled a new 0.47-inch 4K-capable DMD with +/-17 degrees of tilt, which should enhance both brightness and contrast.ĭLP projector makers include LG, Optoma, LG, BenQ and Panasonic. Those tilt either toward the light source (on) or away from it (off) at up to 5,000 times per second.īudget projectors like BenQ’s HT3550i use TI’s 0.47-inch DMD, while higher end models, like the Samsung Premium LSP9T use the 0.66-inch chip. The heart of the tech is an optical semiconductor called a digital micromirror device (DMD) that contains millions of aluminum mirrors. Most projector manufacturers now use DLPs, or digital light processing units, manufactured nearly exclusively by Texas Instruments (TI). That’s essentially a lifetime of use (about 10 years). Lasers are a far better solution than lamps, because they’re brighter and last far longer - up to 30,000 hours instead of 6,000. The rise of ultra-short-throw projectors and brighter long-throw models, meanwhile, has been powered by falling prices in laser illumination technology. ![]() They’re fundamentally different systems, with their own advantages and drawbacks. Here are the basics: Projectors generally use two types of technology, LCD and DLP. This guide will help you understand all that so that you can purchase the best projector for your needs within your budget. There are also a lot of terms to understand, like lens shift, LCD vs. There are a lot of different types of projectors, though, ranging from ultra-short-throw to portable to long-throw. That’s around the same price and over double the size of a decent 65-inch TV, giving you something close to true movie theater immersion with a home theater projector. Better still, you can now get 4K HDR models that can project up to a 150-inch image for as little as $1,000. It'll be one fun weekend project.Over the last year, we’ve seen models bright enough to use in a normal room, short-throw models that take up very little space and have built-in sound bars, and better picture quality than ever with 4K and Dolby Vision features. If you're especially handy, you may even consider wiring your home theater through the wall. If any of the cables in your home theater set-up pose a tripping concern, you should either invest in a small rug or cable-passer or re-route the wire up the wall and away from any high foot-traffic areas. Zip ties are one way to help everything stay organized and in place cable clips and brackets are another. Pillars, crown molding, rugs, and rafters will all be able to help you hide the truth from your esteemed roster of guests. To hide wires in a home theater, we recommend taking advantage of the interior architecture and design scheme of the room. Running a line tidily, in a way that doesn't make your den look like a disaster, isn't always so simple. Something else in this area may present you with somewhat of a challenge, however-running a line is easy. Related: What Is an Audio/Visual Receiver? Do You Need One for Your Home Theater?

Projector screen: Some smart projectors come with an included projector screen.Inputs and outputs: This is probably one factor that you're aware of-you should always check to make sure that you're buying home theater equipment that you have the gear to support.You may also want to take account of the following, just to familiarize yourself with the projector itself: Before getting started, take a look at everything that you're working with and use this opportunity to remove any protective films or seals.
