True colours evoke feelings of sorrow, joy, romance and thrills by preserving the original image. BenQ home cinema projectors embody our belief to “Convey the truest colour and impart the deepest feelings to the viewer.” Our THX and ISF dual-certified engineers deliver 100% Rec. 709 colour gamut for perfect colour consistency. Our top projectors achieve the DCI-P3 wide colour gamut, and only BenQ provides calibration reports, proving Delta E* performance less than 3 to reproduce authentic colours of Hollywood films.
Delta E calculates and quantifies the difference between a reference colour and the projector’s actual colour that attempts to match it, based on L*a*b* coordinates. Representing "a difference in sensation," a Delta E value of 1.0 is the smallest colour difference perceptible to the human eye, and a Delta E value of less than 1.0 is imperceptible.
Colour perception can be subjective - some may see red while others see pink. Rec. 709 colour standard was created by ITU (International Telecommunication Union) for TV, movie and A/V industries to ensure all HD equipment including displays, DVDs, and Blu-rays uses the same colour gamut, resolution, frame rate and video specifications.
Rec. 709 uses specific red, green and blue colours and illuminant D65 (6500k) for the white point to build a standardised color space and reproduce accurate colour gamut and grayscale.
DCI-P3 is a common RGB color space for digital movie projection from the American film industry. Often referred to as "wide gamut," DCI-P3’s range is 26% larger than sRGB / Rec.709. DCI-P3 is expected be adopted in television systems and home cinema as a step towards implementation of the significantly wider Rec. 2020.
Used by Rec. 709 as its white point, Illuminant D65 is a commonly used standard defined by the International Commission on Illumination (CIE) to represent average daylight with a correlating colour temperature of approximately 6500 K.
Sensation comes from reality. CinematicColor™ technology enables reproduction of purest colours, skipping no hardware details related to imaging. BenQ R&D utilises new leading light source technology with strict waveform analysis to ensure that the colour temperature of the projected light accurately reproduces the ultimate colour of the Rec. 709 colour gamut.
Rec. 709 Mode Processing
High Brightness Mode Processing
Light can form beautiful images, but can also damage the colour. For precise light control, BenQ R&D eliminated projection light overflow for an absolutely “black” effect to achieve better ANSI contrast and deeply layered 3D images. Ensuring all light from the source reaches the DMD chip and projection lens, our opto-mechanical structure uses special heat-resistant matte paint and meticulously polished lenses to fulfill Rec. 709 colour gamut requirements.
When watching projected movies, contrast perception is an effect produced by a series of single frames. ANSI Intra-Image Contrast more effectively evaluates the contrast of a series of images instead of the common FOFO contrast ratio. Because it is unlikely that a screen will change from full-black to full-white in normal viewing, a projector with high ANSI contrast will deliver superior depth of field and 3D effects.
BenQ DLP Projectors
Of all DLP projector components, the colour wheel has the greatest effect on colour. Achieving perfect balance between colour accuracy and brightness requires high precision and stringent quality control. Because even nanometer differences create great differences to colour spectrum, BenQ CinematicColor™ uses precise nanometer-level references to test over 20 combinations of colour wheel angle and coating. Each colour wheel is carefully fabricated with high-pure-color coatings to meet Rec. 709 colour gamut requirements and reproduce the true colour of Hollywood films.
BenQ Rec. 709
For home projection to be truly cinema-like, excessive brightness can lower dynamic contrast and cause blackness and color reduction. Proper projection brightness depends on ambient lighting, projection distance, eye comfort, display lifespan and performance. A brightness range of 12-22 fL (foot-lambert) is ideal as scientifically derived by the Society of Motion Picture & Television Engineers (SMPTE) and recognised by theatres around the world. For home projectors with a 120” 1.0 gain screen, the optimum brightness is 1000 to 2000 ANSI lumens.
Using special instruments and software, each CinematicColor™ projector is tested and adjusted for precise D65 colour temperature, gamma, black level, white level, neutral gray, RGBCMY color tracking, hue, saturation, brightness and output from different interfaces based on ITU-R Rec. 709. Collecting all data for individual CinematicColor™ factory calibration reports, we are the industry’s only brand to adopt such high standards of colour gamut and gamma calibration to exceed Rec.709 standards.
