Streaming in HD, 4K, and HDR are all terms related to the quality of video playback:
HD (High Definition): HD refers to a video resolution that is higher than standard definition (SD). It typically has a resolution of 1280 pixels horizontally by 720 pixels vertically (720p) or 1920 pixels horizontally by 1080 pixels vertically (1080p). HD provides clearer, sharper images compared to SD.
4K: 4K, also known as Ultra High Definition (UHD), refers to a video resolution that is even higher than HD. It has approximately 4000 pixels horizontally (usually 3840 pixels × 2160 lines). 4K resolution provides extremely crisp and detailed images, making it ideal for large screens or viewing at close distances.
HDR (High Dynamic Range): HDR is a technology that enhances the contrast and color range of images, providing a wider range of colors and greater brightness levels compared to standard video. This results in more lifelike and vibrant visuals with better detail in both the bright and dark areas of the image. HDR can be used in conjunction with HD or 4K resolutions to further enhance the viewing experience.
Streaming in HD, 4K, or HDR requires compatible devices such as TVs, monitors, or smartphones, as well as a sufficient internet connection speed to handle the higher data requirements of these video formats.
