Is HDR the same as UHD

No, HDR (High Dynamic Range) and UHD (Ultra High Definition) are not the same; they refer to different aspects of video and display technology. - **UHD (Ultra High Definition)**: This term primarily refers to the resolution of the video or display. UHD typically denotes a resolution of 3840 x 2160 pixels (also known as 4K) or 7680 x 4320 pixels (known as 8K). UHD provides more pixels and, therefore, more detail and clarity in the image compared to standard HD (1920 x 1080 pixels). - **HDR (High Dynamic Range)**: HDR refers to a technology that enhances the range of color and brightness in an image. It allows for a greater contrast between the darkest and brightest parts of an image, resulting in more vivid colors and improved detail in highlights and shadows. HDR can be available in resolutions such as HD, UHD, and even lower resolutions, as it is more about the color depth and range than the pixel count. In summary, UHD refers to resolution, while HDR refers to the quality of contrast and color in the image. They can be used together, as many UHD displays support HDR content, allowing for an enhanced viewing experience with both higher resolution and richer color detail.
