![]() ![]() Perhaps due to this, I didn't see any significant pumping that I've seen on some auto iris projectors in the past (although you'll see below in the HDR Viewing section an instance where I could see the Dynamic Contrast working hard), and there's also no clicking or other mechanical sound that can sometimes accompany an auto iris. It's accompanied by a Dynamic Contrast menu setting offering the same three selections previously reserved for the Auto Iris in other models (Off, Normal, and High Speed). (As of mid-March, the downloadable spec sheet on Epson's web page still stated "Contrast Ratio up to and over 2,500,000:1, Auto Iris on.") But after my review process started I discovered that Epson had replaced the Auto Iris from earlier models with a Dynamic Contrast function that adjusts both the laser light source and the panel pixels to dynamically change the contrast. I had it lined up and focused on my 100-inch Stewart GrayHawk in a minute or two.īased upon early information, I expected the LS12000 to have an auto iris like the Pro Cinema 6050UB that allowed it to achieve the rated 2,500,000:1 dynamic contrast ratio. There's powered focus, optical zoom, and lens shift-up to ☙6.3% vertical and ±47.1% horizontal-that makes perfect setup a breeze. The LS12000 has a 2.1x zoom and a throw ratio range of 1.35-2.84:1 (check the ProjectorCentral Epson Pro Cinema LS12000 Projector Throw Calculator to see if it fits in your space). I never saw anything less than an incredibly sharp picture focused from one edge of the screen to the other. Early reviews of the projector commented on a soft picture, but by the time I had my sample ready to evaluate Epson had released a firmware update that addressed the issue. The new Epson VRX Cinema Lens on the LS12000 has a 15-element structure and is designed for zero light leakage. The laser will last up to 20,000 hours to half brightness without the need for maintenance. My measurements in Dynamic mode with light output set to 100% fell just 5% short of the 2,700 lumen spec (which could very well be attributable to the lens shift needed for it to fit my screen while ceiling mounted). The three-chip architecture is also what gives this and other Epson projectors equal white and color brightness. Epson says this design is free of laser speckle that is sometimes visible in other laser projectors, and I didn't experience any speckle at all. ![]() The white light goes through optics that converts it into the three primary colors (red, blue and green) and distributes it to the projector's three 0.74-inch LCD panels. This allows the phosphor to be smaller and quieter than a traditional phosphor wheel. The fixed phosphor is a new design for Epson that has improved heat conductivity and heat resistance. FeaturesĮpson developed a new blue laser diode array that, combined with a fixed yellow phosphor, creates a white light source. And the proof is a very impressive picture and performance, albeit with a caveat or two that might cool the enthusiasm of some. The proof, as they say, is in the pudding. But even with Epson's track record, we all know the specs on the page are only part of the story. The potential for the Epson LS12000 to be a game changer cannot be overstated. And all this for $4,999-less than half the price of its closest laser light source/three-chip competitor, the excellent JVC DLA-NZ7/ DLA-RS2100. The LS12000 also boasts 2,700 ISO21118 (ANSI) lumens of equal white and color brightness, 3LCD imaging with zero chance for rainbow effect artifacts, and support for HDR10+ with dynamic HDR metadata. This is basically the same process used by most single-chip 4K DLP projectors to put up all the pixels of a UHD signal. Epson's first standard-throw projector with a laser light engine in years has four-phase, dual-axis pixel shift technology to put a full 4K (3840x2160) resolution picture on screen from native 1080p imaging chips-the first Epson 4K home theater projector to make that claim.
