Size of the display for this product

The technology used in the display e.g. plasma

Resolution of the display for the system

Brightness is the amount of radiating light emitted from the screen. The brightness rating is measured in candellas per square meter

Type of supported High Definition (e.g. Full HD, 4K Ultra HD).

The aspect ratio is the ratio of the width of an image to its height. The native aspect ratio is the one which the projector/display is particularly designed for. Images shown in native aspect ratio will utilize the entire resolution of the display and achieve maximum brightness. Images shown in other than native aspect ratio will always have less resolution and less brightness than images shown in native aspect ratio.

The response time is the time difference between the moment that a source (for example a video card) sends a signal and that equipment (for example a monitor) receives or display the signal. (Used abbreviations: R/F = Rise and Fall.)

The difference in light intensity between the brightest white and the darkest black.
