Optoma Unveils Next Generation of the HD91 Projector

Jun 01,2015

Justin Halls, Head of Product Marketing at Optoma, says: “The feedback received for the HD91 and its shorter throw version, the HD90, has been excellent so we’re excited to unveil the next evolution of our LED home cinema projectors.”

Screen Shot 2015-05-26 at 4.53.24 PMWith 600,000:1 contrast ratio, increased brightness of 1,300 lumens and 1080p Full HD, the high-end specifications of the HD91+ is powered by three LEDs and delivers enhanced image quality with a wide colour gamut, superior colour saturation and outstanding brightness using separate red, blue and green LEDs to produce intense yet accurate colours. The LED illumination in the HD91+ provides consistent brightness and colour performance to maintain its out-of-the-box image quality throughout its lifetime.  LEDs have up to 33% less power consumption than an equivalent lamp-based projector and need less cooling, which makes the projector almost silent in operation and allows more flexibility in installation.

The HD91+ contains a number of innovative features, not usually seen in a home projector at this price point.  These include:

  •  Installation flexibility: Full lens shift (Vertical: +/- 60, Horizontal: +/-10%).  The wide 1.9x zoom and throw ratio of 1.5 to 2.89:1 makes installation simple.
  •  Full CMS+ for calibration precision: The HD91+ comes equipped with an advanced colour management system, giving flexibility to choose between five preset colour gamuts (Native, Adobe, DLP-C, HDTV and SMPTE-C), six colour temperatures (D50, D65, D83, D93 and Native) or alternatively, to fine tune intensity and x/y co-ordinates of primary and secondary colours for ultimate calibration precision.
  •  It uses 1080p LED technology to provide excellent colour accuracy and sharp detailed images. These LEDs have 20,000 hours lifespan and allow near instantaneous on/off.  And because the HD91+produces less heat than traditional lamp-based projectors, it can be installed close to walls or ceilings or even built into a small enclosure.
  •  Its superior motion handling is due to the latest frame-interpolation technology PureMotion4. This gives advanced motion control processing that eliminates motion blurring or image judder, even in high-speed action sequences and 3D modes.

The projector features DLP technology from Texas instruments which uses millions of tiny mirrors to maximise the available light output and high contrast while completely eliminating crosstalk. This provides a new level of 3D experience with virtually zero rainbow and crosstalk artefacts. Optoma is so confident the colours will remain consistently bright and clear that it provides a five-year warranty for the light source.
