    4K...and 8K...For All

    The 2018 CEDIA Expo wrapped up this weekend in San Diego, leaving projector shoppers and home theater lovers some great new products to ponder and lust after. CEDIA is a trade-only event that restricts attendees to residential and commercial integrators, equipment manufacturers, and industry consultants and press - no consumer walk-throughs. But, no worries if you didn't get to attend. ProjectorCentral was on-site to pore over all the new goodies, so read on.



    Projectors and More Projectors

    The JVC announcement that the company is finally releasing native 4K projectors for the consumer market was among the most welcome at CEDIA. Though not the brightest blasters on the planet, the company's consumer LCOS projectors are renown for their excellent contrast, and it's been a frustration among some hobbyists that JVC has till now stuck with its 1080p pixel-shifters, which accept 4K signals but visually deliver something between 1080p and full 4K resolution. JVC officials said they were determined not to sacrifice contrast for the benefit of higher resolution in their D-ILA models and needed time to perfect the 0.69-inch 4K D-ILA imager found now in three new projectors (technically, six new models including both consumer and commercial designations).

    The entry-level model, designated the the DLA NX5 (consumer) and DLA-RS1000 (commercial) is priced at $6,000 and offers up 1,800 lumens of brightness, contrast rated at 40,000:1 native and 400,000:1 dynamic, a pair of 18 gigabit per second HDMI 2.0 inputs (with HDCP 2.2) and an all-glass, 17-element lens.

    The DLA NX7/DLA-RS2000, priced at $8,000, jumps to 1,900 lumens and an 80,000:1 claimed native contrast ratio, but critically adds JVC's auto-iris techology to deliver dynamic contrast up to 800,000:1. The NX-7 and the step-up NX-9 also feature a new color filter that provides wide color gamut beyond DCI-P3 that should come into play as BT2020-mastered content eventually becomes available.


    The new top-of-the-line is the DLA-NX9/DLA-RS3000. Priced at $18,000, it uses the same 4K D-ILA imagers as the other models but also employs JVC's e-shift pixel-shifting technology to put 8K resolution on the screen. The effect is enhanced by a super-fine, 100mm, 18-element lens. Light output is rated at 2,200 lumens, and thanks to the hand-picking of the imagers and the Intelligent Iris, contrast goes to 100,000:1 native and 1,000,000:1 dynamic. JVC demonstrated this projector with 8K video shot in Peru and Morocco, which was downscaled first to 4K (the highest resolution signal the projector will accept) before the NX9's e-shift function kicked it back up from 4K's 8.8 million pixels to just over 35 million pixels of information delivered to the screen. On a 160-inch diagonal Stewart StudioTek with 1.3 gain in a light-controlled theater, the image was both highly detailed and breathtaking in its color and contrast. Machu Picchu never looked so good, except maybe in person.

    All of the new JVCs are ISF-certified, and feature compatibility with HDR10 and HLG high dynamic range content. New for these models is something JVC calls Auto Tone Mapping. Instead of simply allowing the presence of the HDR flag in content to trigger a fixed HDR viewing mode, JVC looks for the standardized HDR metadata that describes both the peak brightness and average brightness of an individual program, which it then uses to apply adjustments to the playback settings. This should insure best results with individual HDR-encoded titles, which can vary widely in their mastering parameters. When this information isn't available, users can still manually adjust their HDR picture settings from the fixed default.

    The new models will be available in early November. In one last bit of news, JVC said it will retain one 1080p e-shift projector from its existing line-up, the popular and well-reviewed mid-tier model DLA-X790/RS540, for which it is dropping the price from $6,000 retail to $4,000.


    Sony also came to San Diego with three new native 4K models. The VPL-VW295ESreplaces the previous line's VPL-VW285ES, which broke new ground on its introduction in 2017 by being the least expensive native 4K projector (meaning no pixel-shifting) released to that date for the consumer market. The new model retains its predecessor's $5,000 retail price tag and 1,500 lumen output, but utilizes Sony's new generation 4K processor, and like the other new models, offers further improvements that include full 18 Gbps HDMI inputs, Motion Flow motion enhancement for full 4K signals, and a significant reduction of input lag for 4K gaming. As with prior 4K models, all the new projectors are also HDR10 and HLG compliant to take advantage of high dynamic range content. With the VW295 expected to go to market in October, the VW285 is being sold promotionally now for $4,000, Sony execs said.

    The VPL-VW695ES is priced at $10,000 and replaces the VPL-VW675ES as Sony's 1,800 lumen model. As the direct step-up from the VW295ES, it adds Sony's Advanced Iris dynamic aperture to enhance contrast ratio, which is rated at 350,000:1. (Sony publishes no contrast spec for the VW295ES.) The pre-existing VPL-VW885ES, Sony's least-expensive laser-driven projector priced at $25,000 and delivering 2,000 lumens, will remain in the line.

    But the new laser-driven VPL-VW995ES, at $35,000, was Sony's big announcement. It replaces the old lamp-driven VPL-VW1100ES and slips between the VW 885ES and the $50,000 VPL-VW5000ES, bringing significant upgrades. Along with the laser engine and 2,200 lumen output, the VW995ES uses the same high quality ARC-F lens found in the VW5000, and adds an important enhancement not previously found in any Sony consumer laser projector: the Advanced Iris dynamic aperture. The combination of adjustable laser light output with the projector's Dymamic Laser Control plus the ability of the auto iris to dial down the light when needed for dark scenes should greatly enhance the projector's deep black retention. Furthermore, the VW995ES exclusively features the new Digital Focus Optimizer, which processes the signal to help retain fine detail away from the center of the lens that's typically lost as you move out toward the edges of a large screen.

    Meanwhile, Epson, in an effort to show the range of its wares, took the occasion of CEDIA to show integrators an impressive native 4K projector for the large venue market or, alternately, anywhere a large, detailed screen needs to be viewed up close, such as in medical or security applictions, or in simulators. The PRO L12000QNL is a 12,000 lumen beast beast with some sophisticated tech on board, including a front-mounted camera that not only allows operators to remotely view what's on the screen, but also to automatically join the images of multiple side-by-side projectors into a single large image with the help of onboard software.

    Of greater interest to the broad audience was the Pro Cinema 4050 4K Pro UHD. As previously reported, this $2,399 model is a native 1080p pixel-shifter rated for 2,400 lumen light output, and is the first Epson model with the company's new 4K Pro Enhanced pixel-shifting technology. Notably, Epson increased the speed of its pixel-shifting device and with improved processing is able to render crisper detail than with its previous iteration. Epson's show demo bore this out. Projected on a 120-inch diagonal screen, fine details like flyaway hairs on an actor's head or facial stubble suffered no apparent softness I could detect. Another important improvement from prior models is more advanced tone-mapping for HDR content that uses 12-bit processing to reduce banding artifacts, and takes advantage of the extra output afforded by 1080p chips rather native 4K devices, which by nature are more dense and pass less light. Contrast is rated at 200,000:1, considerably less than the pricier Pro Cinema 6040 step-up model that features a dynamic iris. But the 4050's generally striking image, combined with perks like multiple lens memories, powered lens adjustments, and an exceptional range of horizontal and vertical lens shift (none of which are typically found at this price point), should make it an exceptional value.

    In the "if you have to ask you can't afford it" category, Digital Projection Inc. (DPI) made a big impression with a demo of its large venue native 8K projector, the Insight Laser 8K. It offers 7680x3320 pixel resolution with 25,000 lumen output from its multiple laser light engine, and looked stunning on a 220-inch diagonal Stewart StudioTek 100 1.0 gain screen. It ships in October at a price of $299,000. 'Nuff said.

    Wolf Cinema, a company that's made it's name selling high-performance hot-rodded versions of already outstanding projectors from the likes of JVC and others, came to CEDIA with, what is for them, a surprisingly low-cost 4K model that looked amazing. The PRO-817 is a single-chip 4K DLP projector with a laser light engine that costs $9,995, puts out 2,900 lumens, and has a claimed contrast ratio of 2,000,000:1. It was by far the best looking of any of the new 4K projectors I've seen to date that uses Texas Instrument's pixel-shifting DLP chip (the 0.66-inch in this model), and it renewed my faith that in the right hands, TI's cost-effective technology can achieve impressive contrast in a dark-room theater environment. Of course, part of the magic was made by Wolf's optional Pro Scaler processor, which provides a high degree of control for calibration.

    Belas e caras máquinas, infelizmente melhorias quase insignificantes na imagem ainda estão custando muito. O lado bom é que com o dólar tão caro não dá nem vontade de arriscar.

    Acredito que 4k nativo com contraste decente e preço mais honesto, só daqui a mais dois anos, infelizmente.

    Olha cada caso é um caso, ontem estava assistindo aquela serie Jack Ryan em 4k e cada dia fico mais satisfeito com imagem de meu atual JVC, tenho ate medo de começar a procurar novamente por projetores, sem contar parte de ajustes e afins, quase chegando a mil horas

    Olá João,

    Jack Ryan é top, a Prime video está dando um show de qualidade. Assisti o episódio piloto no hw45 e os demais na LG B7p. Bom demais. Foi o melhor dolby vision de streaming, na minha opinião. Mas a imagem em SD também não deixou a desejar.

    obs. Nossa, 1000 horas já! Lembro quando compramos o Sony. O meu ainda está com pouco mais de 550. kkkk

    Amigos, estou planejando uma viagem para Europa em junho de 2019 e pensando em trazer na mala o novo Epson EH-TW9400.

    Alguém já teve a experiência de trazer projetor da Europa na mala?

    Obrigado.
