high-definition

High-definition (HD) refers to a video or image quality that offers greater detail and clarity compared to standard definition. It produces sharper, more lifelike visuals by increasing the resolution—the number of pixels that make up the picture. HD typically includes resolutions like 720p or 1080p, meaning 720 or 1080 lines of pixel data vertically. This results in clearer images with finer details, improved color accuracy, and a more immersive viewing experience. Essentially, HD enhances visual quality, making images more realistic and enjoyable to view on compatible screens.
