Should i turn on hdr on my monitor5/11/2023 ![]() This means they don't have to be cross-compatible with older, SDR screens. HLG was developed by broadcasters to look good on an SDR display, but better on HDR screensÄolby Vision, HDR10 and HDR10+ are being used to various degrees by content streaming services, where it's possible to deliver different streams to users whose systems can report that they're HDR compatible and those that aren't. There's also the more simplistic Hybrid Log Gamma, which is the one you're most likely to have already heard of. ![]() The push toward HDR TV has spawned a series of standards, from the sophisticated Dolby Vision to the less ambitious HDR10, via HDR10+, which sits somewhere in between. The latest HDR TVs allow us to gain this same experience in the home. Directors and DoPs are increasingly shooting and grading their movies to utilize the wider dynamic range offered by modern cameras and displays. ![]() This capability has already been exploited in cinema. And, crucially, this isn't about eye-catching effects, it's about representing the world more realistically. But a new generation of displays: OLED and other high-end TVs and many mobile devices, are able to display a wider range of tones than before. What we currently think of as HDR images are usually high dynamic range scenes tone-mapped to fit into the constraints of standard dynamic range (SDR) displays and print. This means they can show a more convincing representation of the real world, but requires content that makes use of this possibility. ![]() The technologies that make this possible are displays that can achieve a wider color gamut, a greater maximum and minimum brightness than conventional displays, and that can show more subtle gradations of tones from this brightest point down to black. However, it's impossible to convey the capabilities in a JPEG image, viewed on an SDR display, so all we can do is try to maintain the distinction between the sky and foreground. On an HDR monitor, capable of brighter whites and darker blacks, the shadow region would be brighter and able to express more contrast, while the sky would be brighter still and more distinct from the foreground, just as it would be in the real world. This is a necessarily limited representation of the difference between SDR and HDR images, constrained by your SDR display.
