Color gamut is defined as the range of colors that a particular device can produce or record. It is usually shown by an enclosed area of the device's primary colors on the chromaticity diagram. For example, projectors' primary colors are red, green, and blue. Hence, the color gamut of a projector is shown in a triangular area enclosed by the color coordinates of the projector's red, green, and blue colors.
In home theaters, accurately reproducing colors is essential for an immersive viewing experience, ensuring that what you see matches the filmmaker’s original intent.
When evaluating color performance, it's not just about choosing between DLP or 3LCoS technologies—the true indicator lies in the projector’s ability to cover the DCI-P3 color gamut. Wide color coverage ensures faithful color reproduction, regardless of the underlying projection method.
DCI-P3 is the official color gamut standard for the film industry, ensuring that movies are displayed with consistent and accurate colors. However, not all projectors that claim a wide color gamut can fully cover the DCI-P3 spectrum. Some models may achieve a higher percentage but still fail to precisely render every shade within DCI-P3, leading to color inconsistencies and an inaccurate viewing experience. Some projectors may boast a higher percentage but still fail to reproduce the necessary colors accurately, leading to gaps in color consistency. Many commercial movies and HDR content are mastered in DCI-P3, meaning that projectors with full coverage can present these films as intended. Without full DCI-P3 support, colors may appear muted, less dynamic, or inaccurate.
Most entry-level 3LCoS projectors struggle with color accuracy, achieving less than 90% DCI-P3 coverage. This limitation leads to:
When playing HDR content, their narrower color gamut often results in duller, desaturated images, making movies appear lifeless and less immersive. Achieving full DCI-P3 coverage requires more advanced optical components and precise color calibration—factors typically reserved for premium-tier projectors. This is why entry-level 3LCoS models fall short, both technically and in performance.

<Introducing BenQ CinematicColor Technology>
By adopting 100% DCI-P3 coverage, these projectors eliminate the color reproduction gaps found in 3LCoS models, providing a more authentic and visually stunning viewing experience.
BenQ’s 100% DCI-P3 projector (left) shows richer reds, natural greens, and better color balance. In contrast, the entry-level 3LCOS projector (right) displays oversaturated reds and flattened details, failing to reproduce the full DCI-P3 spectrum.
While 3LCoS and DLP are different projection technologies, true color performance depends not on the technology itself, but on how well a projector can reproduce the DCI-P3 color space. Many entry-level projectors—especially 3LCoS-based ones—fall below 90% DCI-P3 due to cost-driven limitations. In contrast, BenQ’s home cinema projectors are designed to meet the full 100% DCI-P3 standard, ensuring every color is faithfully rendered, just as intended in the mastering studio.
For movie enthusiasts and home cinema perfectionists, high-end home cinema projectors like the W5800 and W5850 guarantee the most accurate color reproduction available. Whether enjoying HDR highlights, deep color gradations, these projectors ensure that every frame mirrors professional cinema quality.
