The image quality is determined by brightness, color gamut and color depth. The SDR image can only present a maximum of 100 nits, 8-bit color depth and Rec.709 color gamut content. The HDR 10 image supports up to 1000 nits, 10-bit color depth and Rec.2020 color gamut.
Dolby Vision, the highest level of HDR standard, supports 10000 nits, 12-bit color depth and Rec.2020 color gamut performance. Additionally, it adjusts the picture dynamically on a scene-by-scene and even frame-by-frame basis. Dolby Vision allows you to see more details with better color accuracy, deeper depth, incredible contrast, and a wider range of colors. It constantly makes adjustments so that each image on the screen is optimized.
In addition, the brighter the projector is, the better the picture quality content is generated. By choosing a higher lumen projector, you will receive a higher Dolby vision picture quality.
