Vivitek launches a compact 4K UHD projector option-- the HK2288, built around a recently developed TI 0.66-inch 4K DLP DMD chip able to generate 8.3 million individual pixels.

The projector also offers DLP DarkChip3 and BrilliantColor refinements for optimal black levels. Meanwhile eXpanded Pixel Resolution (XPR) technology uses 4.15 million (2716x1528) mirrors capable of switching over 9000 times per second to deliver two discrete pixels for each mirror per frame, reformulated through video processing to map and reproduce a native 4K image.

The result, according to Vivitek, fully resolves a 4K 1-pixel line pattern and "is indistinguishable from native 4K projection-- unlike pixel-shifting techniques employing standard 1080p chips."

BenQ launches an entry-level 4K UHD projector-- the CineHome HT2550, a single-chip DLP number promising to hit 96% Rec 709 colour gamut, together with native 3840 x 2160 resolution.

The projector uses 0.47-inch single-DMD-chip DLP technology together with BenQ CinematicColor technology and an RGBRGB colour wheel to hit 96% coverage of Rec. 709 colour gamut. In total it can push 8.3 million distinctive pixels, with 2200 ANSI lumens brightness and 1000:1 contrast ratio.

Optoma presents a residential laser 4K projector option-- the UHZ65, a laser-based projector able to produce 4K images as large as 14-inch from just 3.3m distance.

The UHZ65 carries a laser-phosphor light engine producing up to 3000 lumens of brightness and contrast levels reaching 2000000:1 with Dynamic Black enabled. A Texas Instruments (TI) 4K DLP UHD chipset includes XPR processing to display 8.3 million pixels, while PureMotion image processing technology eliminates noise, motion blur and judder in fast-motion video.

Epson takes the short-throw projector category to the home market with the EH-LS100, a laser-powered ultra-short-throw (UST) projector promising flexible installation options and images of up to 130-inch.

The EH-LS100 can be placed just 6cm away from a wall or screen to project a 70-inch WUXGA resolution image, with a bit more of throw distance allowing for larger images. A combination of 3LCD technology and White and Colour Light Output (CLO) of 4000 luments allow it to handle high-ambient light conditions, while Detail Enhancement provides smoother and sharper images. Contrast ratio stands at 2500000:1.

Connectivity comes through x3 HDMI inputs (including x1 MHL), while control comes through either RJ45 connection or wifi connectivity via optional ELPAP10 adapter. Both options allow one to control the projector via smart device and companion iProjection app. Built-in 16W speakers provide sound.

Barco Residential announces the Medea-- a native 4K (3840x2160) resolution projector with HDR10 support designed as an entry-level home cinema option.

It is powered by a new optical engine and laser light source providing what the company claims is significantly improved image uniformity, together with nearly instant on/off and light source life reaching up to 40000 hours. A liquid cooling system allows the projector to operate in any orientation.

Installers get a choice of 7 all-glass lens options, wide lens shift and a "unique" built-in warp engine for flexibility in terms of projector positioning and architectural integration. The control system is identical to the one found in the Balder and Loki projectors, with comprehensive PC-based remote configuration and control from the best seat in any home theatre or media room.

CEDIA 2017 sees Sony launch an entry-level 4K HDR home theatre projector-- the VPL-VW285ES, a projector promising a (relatively) lower-priced option for customers wanting to upgrade their cinema and gaming experience.

The VPL-VW285ES offers real 4K output, with resolution reaching 4096 x 2160. It also adds HDR through HDR10 and HLG (Hybrid Log-Gamma) support, while colour is further boosted through the addition of Triluminos technology. Brightness reaches 1500 lumens, and Sony claims operation time totals up to 6000 hours.

For customers wanting a fancier projector Sony also has the VPL-VW385ES, a mid-tier projector with 200000:1 Dynamic Contrast, "Advanced Iris" for improved detail and less image artifacts and Sony Reality Creation upscaling, and the high-end VPL-VW885ES featuring 2000 lumens brightness, "infinite" dynamic contrast with real-time laser light control and 20000 hours lamp life.
