![]() With content that uses static metadata, the brightness remains the same throughout, meaning some scenes can be over-brightened or not dark enough. ![]() It means that if content uses dynamic metadata, it can lower its peak brightness for a darker scene and increase its brightness for a brighter scene to make highlights pop, so it has a clear advantage. Dynamic metadata changes on a scene-per-scene basis, while static metadata remains the same for the whole length of the movie or show you're watching. There are different types of HDR signals that can be sent, and they're either with static or dynamic metadata. ![]() The HDR image appears more life-like, and you can see more details in darker areas, like in the shadows of the cars. Having a TV with HDR support doesn't necessarily mean HDR content will look good, as you still need a TV that can display the wide range of colors and brightness required for good HDR performance. You can see an example above of what an HDR image looks like compared to an SDR image on the same TV. In the case of TVs, SDR is a specific set power, while HDR is a set goal. For example, with SDR, a car would be ordered to apply "full throttle" or "50% throttle." Instead, the HDR car would be asked to "go to 120 mph" and "go to 40 mph." Some vehicles would provide a worse experience than others working towards this task, and most might not even succeed. The source tells the TV what exact color to display at which exact brightness level, whereas SDR is limited to a range of brightness and colors. HDR signals send metadata to your TV, which is a list of instructions for the TV to display content properly. HDR (High Dynamic Range), as the name suggests, introduces a wider range of colors and brightness levels compared to SDR (Standard Dynamic Range) signals.
