What does Native display resolution mean?
Native display resolution is the fixed pixel grid of a digital panel. It describes the display’s physical sampling structure, rather than the dimensions of every programme shown on it.
Why it matters
Incoming video is scaled or otherwise mapped to that grid. A television with a 3840 × 2160 panel can display an HD source, but the necessary enlargement does not make the original programme native 4K. The player’s output mode and the source’s encoded dimensions are additional measurements that should be kept separate when discussing picture quality or compatibility.
A practical example
For example, a box can receive a 1920 × 1080 channel and send a 4K HDMI signal to a 4K television. The television uses its native grid, while the channel still contains the detail of its original HD source.
