Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 × 768 pixel array).
In the case of television inputs, many manufacturers will take the input and zoom it out to "overscan" the display by as much as 5% so input resolution is not necessarily display resolution.
The eye's perception of display resolution can be affected by a number of factors – see image resolution and optical resolution.
One factor is the display screen's rectangular shape, which is expressed as the ratio of the physical picture width to the physical picture height.
