Superior Performance

Created for discerning viewers the HD91 sets a new standard for colour performance with consistent, breath-taking, perfectly balanced colours from the first time, every time and for years to come. Whether you just fancy a relaxed movie night or immersing yourself in adrenaline-pumping 3D, the HD91 is the perfect choice for recreating the big-screen experience.

Optoma LED technology

Powered by 3 x LEDs, the HD91 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. Advanced switching of these LEDs provides increased image stability that rivals the performance of 3 chip DLP projectors.

Performance is nothing without consistency. Unlike traditional lamp technology the LED illumination in the HD91 provides consistent brightness and colour performance, so maintaining its out-of-the-box image quality throughout its lifetime and saving you from costly calibrations.

The benefits don’t stop there. In many situations the perceived brightness of the HD91 LED projector can be up to twice the brightness of an equivalent lamp-based projector. Utilising this phenomenon, known as the Helmholtz-Kohlrausch (HK) effect, the HD91 produces vividly intense colours. This enhanced brightness perception enables the HD91 to comfortably render screen sizes far higher than its ANSI brightness specifications would suggest. This allows the HD91 to handle low levels of ambient light with less impact on image quality than lamp based systems.

Finally, the lamp-less LED illumination engine that powers the HD91 does not require the inconvenience and cost of frequent lamp changes to maintain its optimal performance. It also doesn’t need lengthy warmup and cool down cycles before and after every viewing due to its almost instant start up and shut down times.
