What is Contrast Ratio?
Posted by Carl Troy on 20 May 2010 01:08 PM
The contrast ratio is a measure of a display system, defined as the ratio of the luminance of the brightest colour (white) to that of the darkest colour (black) that the system is capable of producing. A high contrast ratio is a desired aspect of any display.

Different manufacturers measure the contrast ratio of their sets differently and some only realease the figure for the Dynamic ratio rather than the true Native ratio. Dynamic ratio is an artificial ratio caused by the TV automatically dimming the screen when it detects a dark picture and brightening the screen when it detects a light picture. The Native ratio is the true ratio of the screen.

This means that although some models may seem to have a really low ratio compared to another set, the picture quality may be similar or even better depending on the manufacturer.
