When BenQ recently announced the launch of the BenQ MP770 DLP projector it noted its most prominent features as;

• BrilliantColor™ technology for better color saturation and brightness.
• BenQ’s proprietary Senseye color enhancement technology
• A whisper quiet design
• High brightness of 3200 ANSI lumens
• Long lamp life of up to 4000 hours

BrilliantColor

BrilliantColor is a Texas Instruments trademarked technology 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.

Senseye colour enhancement

BenQ’s Senseye colour enhancement technology is marketed as being able to accurately render the subtlest of tints such as natural pastels and skin tones, correct hue and saturation levels and colour intensity. A specialized colour wheel coating delivers better color saturation for red and blue.

Quiet Projector

With 28dB in economic mode quoted, the BenQ MP770 won’t be drowning out conferences or presentations – normal conversation is over 60dB.

Brightness

With a high brightness of 3200 ANSI lumens, the BenQ MP770 makes it possible to deliver a bright projected image even in well illuminated environments and larger size venues such as conference rooms. However, projected image brightness is affected by a number of factors and individual situations need to be considered before making a purchase.

Long Lamp Life

BenQ MP770 features a lamp life of 4000 hours, which is almost 2 years with 8 hours use each workday.

Contrast Ratio

The quoted contrast ratio is 2000:1 however, the testing method was not stated. Full On/ Full Off tests deliver higher test results than the ANSI test. However, the figure is satisfyingly high and matches what would be expected of a projector which can be used in well illuminated environments.

Portability

At 6.6 pounds the unit falls into the definition of a portable projector.

Useful Features

• Horozontal and Vertical keystone correction of up to ±40% vertically and ±20% horizontally providing installation flexibility with positioning of the projector in relation to the centerline of the projection screen;
• extra-fine dust filter that prevent microscopic debris from entering the projector and foreshortening its life;
• An advanced off & go feature allowing the projector to be continually cooled off after the projector is unplugged;
• An auto-off functions enables the projector to automatically shut down when no data source is detected for a predetermined time, saving power and preventing overheating of the projector;
• A password protection function which prevents unauthorized use of the projector by requiring a correct password be entered before an input source is accepted;
• Picture-In-Picture for simultaneous displaying two different input sources;
• the BenQ MP770 offers 800% zoom;
• My Screen which is a feature allowing you to configure your own start-up screen to any image you like such as a company logo for corporate units;
• Optional wireless function enables a cable-free connection and quick changeover if multiple video sources are used.
