HD Television, or High Definition Television, refers to a television system that provides a higher resolution than standard-definition television. This means that images are clearer and more detailed, enhancing the viewing experience. HD TVs typically come in various resolutions, such as 720p, 1080p, and 4K, with 1080p being the most common for high-definition content. To enjoy HD content, viewers need an HD-compatible television and a source of HD programming, such as cable, satellite, or streaming services. Many movies, shows, and sports broadcasts are now available in HD, making it a popular choice for home entertainment.
