Thats why I'm not in here anymore.
Contrast ratio is supposed to basically be a measurement of how dark the black is, and how bright the white is with a black pixel, right next to a white one.
The higher the number the better.
Now HOWEVER, be aware of a few things.
1. There is no standard in the industry to measure this stuff. So sony's 5,000:1 could be Samsung's 3,000:1 for all we know.
2. Plus, most companies (mainly LCD yet we are starting to see plasma's do the same thing) seem to put their DYNAMIC contrast ratio. Now this is a whole other beast. Essentially this is supposed to be the television's max capability as far as contrast goes. However, this is given all the proper situations, or the most perfect
picture situation. (That would be highly unlikely to occur during normal viewing)
This is also sometimes not labeled as dynamic at some places though.
Knowing the base Contrast ratio's for certain technologies can help you figure this.
LCD is usually 500:1 to about 5,000:1 or so non-dynamic with dynamic @ as high as 500,000:1. So usually anything over 5,000:1 may be dynamic even if not labled as so.
PLASMA is usually 10,000:1 to about 15,000. You tend to not usually see Dynamic measurements from plasma, but with LCD's doing it so much, we are started to see it... The new 1080p 42 Panny boasts 1,000,000:1 dynamic, but I think its 15,000:1.
In my opinion, its just a made up stat for the most part. I see tons of people shopping tv's by just what the tag says. Just look at the tv and see for yourself how good the black and whites are. There has always been a clip in the demo feed at best buy that has snow in it. Look for Snow next to dirt, trees, dark water, or dark sky. Sometimes the snowy areas tend to cause those dark areas look gray in the areas close to white, instead of black.
