Optoma launches 1080p LED home cinema projector

The new HD91 DLP model produces images up to 150in (380cm) diagonal, has a 500,000:1 contrast ratio and integrated 3D technology.

Optoma‘s new HD91 DLP model produces images up to 150in (380cm) diagonal, has a 500,000:1 contrast ratio and integrated 3D technology.

Powered by LED technology, the HD91 delivers enhanced image quality with a wide colour gamut, superior colour saturation and uniform brightness. Advanced LED switching provides increased image stability that is said to rival the performance of 3-chip DLP projectors.

Unlike traditional lamp technology, the projector’s LED illumination provides consistent brightness and colour performance throughout its lifetime. It also doesn’t require lengthy warm-up and cool down cycles each time it is used.

The energy efficiency of the LED means that less cooling is required than for conventional projectors. Not only does this result in near-silent operation, it also means that the HD91 can be installed closer to walls or ceilings or even built into a small enclosure. Its light weight (7kg) and compact size simplify installation, while full lens shift and wide 1.9x zoom range offer placement flexibility.

Special image processing algorithms and a dedicated image detail processor are said to give the impression of near 4K image quality without the artefacts associated with moving pixel systems. In addition, PureMotion4, the fourth generation of Optoma frame insertion technology, provides advanced motion control processing that eliminates motion blurring or image judder, even in high-speed action sequences and 3D modes.

PureColour technology is said to provide balanced colours for vibrant, vivid and natural images. This works in conjunction with the Colour Management System for precise control of colour reproduction.
Improved by ultra-fast LED switching times, Dynamic Black technology dynamically adjusts brightness frame by frame to produce deeper blacks in dark scenes.

“The new HD91 with matte-black design is the first LED home cinema projector from Optoma. It brings big screen Full HD LED cinema into the home and delivers a truly spectacular experience for film fanatics,” said Justin Halls, head of product management at Optoma EMEA.
