What are HD, Full HD, Ultra HD, 2K, 4K, 8K and 10K resolutions?
LED Screen resolutions describe the number of pixels (individual colored dots) that make up an image on a LED display, usually written as width × height. The "K" in 2K, 4K, and 8K stands for "kilo" (thousand), indicating the approximate number of horizontal pixels.
Main Resolutions
A breakdown of each resolution standard, from standard HD to ultra-premium 10K, highlights these differences:• HD (High Definition / 720p): 1280×720 pixels. 16:9 aspect ratio. Total: ~921K pixels. Still the live streaming standard on many platforms and cable TV channels.
• Full HD (FHD / 1080p): 1920 × 1080 pixels. 16:9 aspect ratio. Total: ~2.07 million pixels. This is the long-standing gold standard and remains the most common format for standard TVs, computer monitors, and streaming services (like YouTube).
• 2K: 2048 × 1080 pixels. Primarily a professional Digital Cinema Initiatives (DCI) standard used in movie theaters. In the consumer market, monitors or phones labeled as 2K often actually use Quad HD (2560 × 1440) screen resolution.
• Ultra HD (UHD) / 4K: 3840 × 2160 pixels. This is the modern standard for most new TVs and high-end gaming monitors. It packs exactly four times the pixels of Full HD. (Note: True DCI 4K used in filmmaking is slightly wider at 4096 × 2160).
• 8K (FUHD / 4320p): 7680 × 4320 pixels. Providing four times the resolution of 4K, this is mostly reserved for massive premium TVs and digital signage where incredibly high pixel density is required for huge screens.
• 10K: 10240 × 4320 pixels. An ultra-premium and experimental format typically used in professional simulation environments, research labs, or massive panoramic digital led video walls, rather than for home entertainment.
