The BenQ MP771 DLP projector is a projector with a significantly short throw capability. The MP771 is actually the first of a series of new projectors which will share the short throw feature. Having a short throw distance makes the MP771 suitable for use in cramped spaces which would have projectors with a longer throw producing an unacceptably small image. As an example of its capability, it is able to project a 74-inch image from only one meter.

Other features providing the MP771 with flexibility of use are the high 3000 ANSI lumens brightness and Wall Color Correction Technology allowing it to project acceptably bright and clear images in bright ambient lighting and against colored walls respectively. A high 2000:1 contrast ratio boosted by the Unishape Lamp Lighting technology will provide images with sharper detail.

The MP771 has an XGA (1024 x 768) resolution in line with its intended use in business and educational environments. BenQ have included numerous features to benefit users in these environments such as; a corporate splash screen, detachable keypad, security password, 12 trigger for a projection screen, auto off, presentation timer, quick cooling and a top access lamp door for easy lamp replacement and maintenance.

Unishape Technology

BenQ’s Unishape Lamp Lighting Technology built into the MP771 was developed by OSRAM. It was developed by OSRAM to improve projection technologies and lower the cost and complexity of DLP projection. The performance boost to projection systems utilizing Unishape is advertised by OSRAM as being:

• 40% greater brightness
• 60% less dithering noise
• at least 80% more colors
• up to 100% higher contrast

BrilliantColor

The MP771 incorporates BrilliantColor which is a Texas Instruments trademarked technology for delivering improved brightness and a wider range of colors. Traditionally, most display devices render images using a combination of the three primary colors red, green and blue. The full gamut of colors visible to the human eye cannot be reproduced using this approach, with the color space subset covered not including vivid colors such as yellow and cyan commonly seen in nature. By processing up to six color channels BrilliantColor allows vendors, such as Benq, to create multi-primary color systems by adding colors such as yellow, cyan and magenta colors for color rendering. As well as increasing the color space which can be rendered with the added color filters the system also utilizes the light source more efficiently with a 50% increase of 50% brightness.

Another benefit of BrilliantColor technology derives from its use of floating point arithmetic for more accurate rendering calculations. According to Texas Instruments, this results in less noise and more accurate colors at the display with over 200 trillion color shades being possible.

Replacement bulbs are a large expense for projector owners and the longer they will last the better. The MP771’s average use time of 4,000 hours is definitely something in its favor.
