HD television refers to high-definition television, which provides a clearer and more detailed picture compared to standard-definition TV. It typically has a resolution of 720p, 1080p, or higher, meaning it displays more pixels on the screen. This results in sharper images and vibrant colors, enhancing the viewing experience for movies, sports, and other content. To enjoy HD television, viewers need an HD-compatible TV and an HD source, such as a cable box, streaming device, or Blu-ray player. Many broadcasters and streaming services now offer content in high definition, making it widely accessible for audiences.
