- Improved Viewing Angles: Higher resolution allows for better viewing experiences from wider angles, meaning you can watch with a larger group without compromising quality.
What is HDR?
HDR stands for High Dynamic Range, and it significantly impacts how colors and brightness are rendered on your screen. Whereas standard dynamic range (SDR) TVs can only display a limited range of colors and brightness, HDR technology enables televisions to showcase a wider range of brightness levels and color palettes.
How HDR Works
Generally, HDR works by increasing the brightness and the contrast between the darkest and brightest parts of an image. This creates a more realistic and immersive viewing experience.
Understanding HDR Standards
There are several HDR formats available today, the most common being:
- HDR10: The baseline HDR format that most 4K TVs support. It offers a static metadata system, meaning it applies to the entirety of the content.
- Dolby Vision: A more advanced form of HDR that uses dynamic metadata. This means color and brightness adjustments can change on a scene-by-scene level, improving the viewing experience.
- HDR10+: Similar to Dolby Vision, HDR10+ also utilizes dynamic metadata to optimize scene-by-scene brightness and colors.
Each format aims to make HDR content look as good as possible on equipped devices, thus allowing viewers to enjoy cinematic visuals right in their living rooms.
How 4K and HDR Work Together
When combined, 4K and HDR create an enriched visual experience. The resolution offers clarity and detail while HDR enhances the visual richness through vibrant colors and enhanced brightness contrasts. This partnership provides a viewing experience that can often resemble being in a theater rather than watching at home.
