At the heart of the HD91 is a revolutionary new lighting system. Rather than using a conventional blub, the HD91 utilises 3 x LEDs for enhanced performance and longevity. In terms of colour performance and brightness, LED is far more consistent than tradition bulbs, ensuring not just a great picture when new but also one that lasts throughout the projector's lifetime. The perceived brightness is also far greater with LED technology, giving lifelike colour and realism that a similar conventional projector would struggle to match. Finally, LED lamp technology should be far longer lasting, without the need for expensive lamp replacement every few years.

PIN SHARP DETAIL FROM TEXAS INSTRUMENT'S DLP CHIP

Using Texas Instrument's DLP technology, the Optoma HD91 gives crystal clear clarity, sharply defined images and true, natural colour. Even at larger screen sizes, the detail is astounding and easily a match for the class best. In order to make the most of high definition video sources, the HD91 will also project 1080p Full HD images, making it the perfect match for your Blu-ray player or Full HD gaming device. In addition to this, the HD91 is also 24P compatible. This means that it will replay films shot at 24 frames per second at the correct speed, without glitching.

PUREMOTION4 FOR THE VIRTUAL ELIMINATION OF BLUR

The real beauty of the PureMotion4 system is the ability to tailor the setting according to the film type. For fast action sports or action movies, the highest setting virtually eliminates annoying motion blur. For a documentary or slower paced film, reduce the setting to its lowest level and you'll maximise the detail within every frame.

WITH FULL 3D

Impressive as the Optoma HD91 is in 2D, it's only when you take advantage of the optional 3D system that the picture becomes truly immersive. With the optional ZF2100 3D glasses system, simply connect up to a suitable source and enjoy 3D images that are every bit as bold as at the cinema. Rather than using Infra-Red, the HD91 uses a Radio Frequency system. This not only reduces the chance of interference but also provides a higher contrast and brighter images. The glasses are also fully rechargeable. With 2D-3D conversion you also get the opportunity to see all your favourite 2D films in 3D!

FULLY CONNECTED

With twin HDMI sockets, VGA input, component and composite, the HD91 is well equipped to handle a wide variety of sources. 12V trigger connectors are also included as is an RS232C socket, making this projector ideal as part of an extensive home automation system.

Making the best use of the latest technology, the Optoma HD91 has truly moved the game on: and then some!
