HD, or High Definition, refers to a display resolution of either 720p or 1080p. The most common HD standard today is 1080p, also known as Full HD, with a resolution of 1920×1080 pixels. This means that the screen is made up of over 2 million pixels, providing sharp images and solid picture quality.
HD became the industry standard over the past decade and is still widely used today. It’s common in most cable TV broadcasts, online streaming services, and mid-range devices like budget smartphones or tablets. While HD offers solid performance for smaller screens or casual viewing, it’s not as sharp or detailed as more advanced resolutions like UHD.
Common uses for HD:
- Streaming services like Netflix, YouTube, and Hulu
- Cable and satellite TV
- Gaming on older consoles like the PlayStation 3 and Xbox 360
- Lower-budget or smaller TV sets
