A display is called an HDR display if it can accept HDR content and map it to its display characteristics, [28] so the HDR logo only provides information about content compatibility and not display capability. Displays that use global dimming, such as most edge-lit LED displays, cannot display the advanced contrast of HDR content.
HDR10 is supported by a wide variety of companies, which include monitor and TV manufacturers such as Dell, LG, Samsung, Sharp, VU, Sony, and Vizio, [8] [9] as well as Sony Interactive Entertainment, Microsoft and Apple which support HDR10 on their PlayStation 4, Xbox One video game console and Apple TV platforms, respectively.
High-dynamic-range rendering (HDRR) is the real-time rendering and display of virtual environments using a dynamic range of 65,535:1 or higher (used in computer, gaming, and entertainment technology). [6] HDRR does not require a HDR display and originally used tone mapping to display the rendering on a standard dynamic range display.
Logo. HDR10+ [1] is a high dynamic range (HDR) video technology that adds dynamic metadata [2] to HDR10 source files. The dynamic metadata are used to adjust and optimize each frame of the HDR video to the consumer display's capabilities in a way based on the content creator's intentions.
Another aspect of HDR rendering is the addition of perceptual cues which increase apparent brightness. HDR rendering also affects how light is preserved in optical phenomena such as reflections and refractions, as well as transparent materials such as glass. In LDR rendering, very bright light sources in a scene (such as the sun) are capped at 1.0.
Only the last display in the daisy-chain does not need to support the feature specifically or have a DP output port. DisplayPort 1.1 displays can also be connected to MST hubs, and can be part of a DisplayPort daisy-chain if it is the last display in the chain. [39]: §2.5.1
[7] [8] ITU specifies the use of PQ or HLG as transfer functions for HDR-TV. [7] PQ is the basis of HDR video formats (such as Dolby Vision, [2] [9] HDR10 [10] and HDR10+ [11]) and is also used for HDR still picture formats. [12] [13] PQ is not backward compatible with the BT.1886 EOTF (i.e. the gamma curve of SDR), while HLG is compatible.
Requirements include removing the minimal frame rate and setting a maximum on screen latency. FreeSync Premium Pro also doubles the color volume with support for wide color gamut color spaces and increased display brightness, enabling direct support of HDR-capable displays by video-card device driver and application software.
