Video resolution in pixels refers to the number of individual picture elements (pixels) that make up a video frame, both horizontally and vertically. Higher pixel counts result in sharper, more detailed images. Common resolutions include 480p (640x480), 720p (1280x720), 1080p (1920x1080), 2K (2560x1440), 4K (3840x2160), and 8K (7680x4320).
A 4K resolution, in the context of digital displays, typically refers to a horizontal resolution of approximately 4,000 pixels. The most common 4K resolution is 3840 x 2160 pixels, which is often referred to as Ultra High Definition (UHD).
That means the TV has 3,840 horizontal pixels and 2,160 vertical pixels, for a total of about 8.3 million pixels. On TV product specifications, resolutions are usually shown as "3840 x 2160" for 4K TVs.Here's a breakdown of common video resolutions:
- 480p (SD): 640x480 pixels. A standard definition resolution, once common but now considered low quality.
- 720p (HD): 1280x720 pixels. Considered the lowest resolution to still be called High Definition (HD).
- 1080p (Full HD): 1920x1080 pixels. The industry standard for clear, crisp HD video.
- 2K (QHD): 2560x1440 pixels. Provides more room for editing and larger displays.
- 4K (Ultra HD): 3840x2160 pixels. Offers significantly more detail than 1080p, and provides more flexibility for zooming and reframing.
- 8K (Ultra HD): 7680x4320 pixels. The highest resolution currently available, offering the most detail.
