Contrast is one of those terms that gets thrown around a lot, but isn't often defined. Here's what I have gathered so far:
Contrast ratio
Measures the difference between the brightest whites and the darkest blacks a display can show. The higher the contrast ratio, the greater the ability of a display to show subtle color details and tolerate ambient room light. Contrast ratio is an important spec for front projectors, as well as flat-panel plasma and LCD TVs.
I've also read that rated contrast and "real world" contrast are two different things. For example, on the FlatTVPeople website they stated Plasmas often have rated contrasts of 3000:1, but in the real world they only get around 200:1. They went on to say that LCD TVs get 450 to 500:1 real world. (non-projection)
In an AVSforum thread I read the Sony GWIII's have a ratio of around 400:1. This was tested by a tech. I've never seen a manufacturer's number. I'm getting the 60" XBR Friday, and was wondering what this reduced contrast ratio might mean for the image and how I might stress the contrast ratio to see if this is something that bothers me.
Direct help or a link would be greatly appreciated. First to post is invited to my house to watch the game!
To clarify, first post that enlightens is invited
