4K vs. HD: Every TV Resolution Explained, From 720p to 8K and Beyond

The guide explains common TV resolutions, from 720p and 1080p to 4K/UHD and 8K, and how they differ.

On consumer TVs, 4K usually means 3,840 x 2,160 pixels, while 8K is 7,680 x 4,320 and has four times as many pixels as 4K.

Higher resolution does not automatically mean better picture quality, since panel tech, HDR, and processing also matter.

8K content is still very limited, so 4K remains the practical standard for most large TVs.
