High Definition, often abbreviated as HD, refers to a resolution that provides a clearer and more detailed image than standard definition. Typically, HD displays have a resolution of 1280x720 pixels (720p) or 1920x1080 pixels (1080p). This higher pixel count allows for sharper images, making it ideal for watching movies, playing video games, and viewing high-quality content. The term is commonly used in the context of television, video streaming, and digital photography. With the rise of 4K and 8K resolutions, which offer even greater detail, HD remains a popular choice for many consumers seeking improved visual experiences.
