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.
