User Manual

To determine the Color Light Output of a given projector, three RGB (red, blue, green) color patterns are
divided into nine separate areas. The luminance of the nine areas is then measured for each pattern,
and an average value taken for each. Finally, the Color Light Output is calculated by adding the average
values of the three patterns.
For optimal color performance, consumers should select projectors with specifications showing high
Color Light Output, equal to the White Light Output. A high Color Brightness projector offering 3000
lumens of Color Light Output will also offer 3000 lumens of White Light Output. Projectors bearing a
Color Light Output specification provide consumers with information on both White and Colored Light
Output.
Color Light Output Key to Projector Purchase
The importance of the new standard is shown in a recent study by the analyst group TFCinfo Associates,
a leading strategic market research and publishing firm specializing in the audiovisual market. TFCinfo
interviewed some 537 respondents purchasing projectors from leading retailers or respected internet
sites.
The survey asked ten questions of these potential projector buyers. The results, as shown below, make
it clear that color performance is a critical consideration in the projector purchase decision:
1. 86 percent of respondents projected color content
2. 89 percent said image quality is the most important factor in choosing a projector
3. 97 percent said brightness is the most important projector image quality specification
4. 99 percent said color is an important aspect of image quality
5. 79 percent of projector buyers thought color was part of the current (white) brightness specification
6. 79 percent of buyers expect the image quality of projectors to be comparable if similarly priced
7. 86 percent said Color Brightness is important when making a buying decision
8. 83 percent of buyers want Color Brightness information shown on the package and other materials
9. 91 percent said showing Color Brightness data would have a significant impact on purchase decisions
10. Buyers are willing to pay 19 percent more for projectors with higher Color Brightness
Many of the respondents were sophisticated buyers who purchase multiple projectors. Yet just 28
percent of such buyers surveyed on a leading projector website knew that the current brightness
specification used in marketing projectors measures only White Light Output. Conversely, an
overwhelming 72 percent of respondents believed, incorrectly, that the specification measured Color
Light Output as well.
