In this way, traditional sRGB content automatically gets color-accurate behavior, while advanced color-aware apps can take advantage of the full color capabilities of the display.

Windows then color-converts the composed framebuffer content to the display's native color space. When advanced color is enabled, the DWM performs an explicit color conversion from the app visual content's colorspace to a canonical composition color space, which is scRGB. The Desktop Window Manager (DWM) is Windows' compositor. Windows advanced color adds automatic system-level color management. However, the vast majority of apps and visual content assume that the display is sRGB, and they rely on the operating system to fulfill this assumption. This meant that if a DirectX app rendered, for example, a pure red or RGB(1.0, 0.0, 0.0) to its swap chain, then Windows would simply scan out the most saturated red that the display could reproduce, regardless of what the actual color gamut of the display was.Īpps that needed high color accuracy could query the color capabilities of the display (for example, using ICC profiles), and perform their own in-process color management to correctly target the display's color gamut.
However, prior to advanced color, Windows didn't perform any system-level color management for applications. And these wide gamut displays are becoming more common.

High end, professional PC displays have long supported color gamuts that are significantly wider than sRGB, such as Adobe RGB and D65-P3. The diagram below is a representation of the human "spectral locus", or all perceivable colors (at a given luminance level), where the smaller triangle is the sRGB gamut. However, mainstream consumer displays can often reproduce colors only within the sRGB gamut, which represents only about 35% of all human-perceivable colors. The most saturated natural color the human eye can perceive is pure, monochromatic light such as what is produced by a laser. Wide color gamut with automatic system color managementĬolor gamut refers to the range and saturation of hues that a display can reproduce. New HDR displays, including those that comply with the HDR10 (BT.2100) standard, break through this limitation. However, a typical standard dynamic range display can reproduce only a little more than 3 orders of magnitude of luminance, and therefore any HDR-rendered content had to be tonemapped (compressed) into the limited range of the display. Real world scenes, such as this sunset, often have dynamic ranges of 10 orders of magnitude of luminance the human eye can discern an even greater range after adaptation.Įver since Direct3D 9, graphics engines have been able to internally render their scenes with this level of physically accurate fidelity. High dynamic rangeĭynamic range refers to the difference between the maximum and minimum luminance in a scene this is often measured in nits (candelas per square meter). The most common type of advanced color display, HDR10, supports all three extended capabilities. The three major extended capabilities are described below.

Windows advanced color refers to several related technologies, first introduced with Windows 10 version 1703, that provide support for displays that exceed the color capabilities of traditional standard dynamic range (SDR) displays. You can use Direct3D, Direct2D and other graphics APIs to render HDR content to a capable display. Windows 10 supports HDR and other advanced color displays, which provide significantly higher color fidelity than traditional SDR displays. It also covers the key technical requirements for your app to properly support Windows advanced color, as well as recommendations and best practices. It summarizes some key conceptual differences between outputting to HDR10 displays as compared to traditional standard dynamic range (SDR) displays. This topic provides a technical overview of outputting high dynamic range (HDR) Direct3D 11 and Direct3D 12 content to an HDR10 display using Windows 10 advanced color support.
