The number of pixels in a video image — higher means sharper picture.

Explanation

Video resolution is the number of pixels in the image, expressed as width × height. Common streaming resolutions are SD (480p), HD (720p), Full HD (1080p), and 4K UHD (2160p). Higher resolutions need faster internet connections. Most streaming services offer up to 4K on their premium plans.
