LCD projectors tend to be sharper, more efficient and more color accurate, but have lower contrast ratios and can experience image degradation over time. 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 buying guide will help you with everything you need to understand before purchasing the best projector for your needs within your budget.īest ultra-short-throw projectors under $3,500īest ultra-short-throw projectors under $7,000īest budget portable projectors The t echnology 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 an image size up to 150-inches for as little as $1,000. Both enhanced and true 4K projectors show excellent, fantastically detailed images, and the difference is still visible when projected onto the cinema screen.ĤK is superior in terms of quality, details, sharpness and all other aspects you look for in creating your home cinema experience, and nowadays it doesn’t have to be an expensive investment, as 4K projectors are increasingly more affordable.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. Enhanced 4K mainly refers to a more limited and slower version of pixel shifting technology, which mostly shows 2K resolution, or 4.1 megapixels, but fired twice to seemingly show 8.3 megapixels on the screen. This delivers a 3840 x 2160 resolution with 8.3 million distinct pixels for each frame, four times higher than full HD 1080p. True 4K is 8.3 megapixels, and is considered as showing true 4K resolution by using a DLP 4K UHD chipset with advanced image processing, ensuring incredibly fast pixel switching speed. Both of these play 4K content, but there is a difference. There are mainly two kinds of 4K projectors: true 4K projectors and enhanced 4K projectors.
