"Dynamic Contrast" Ratio vs "Contrast" Ratio?

Looking to buy an LCD TV, I've been comparing specs. ...

Some TVs have a "Contrast Ratio" of, say, 1200:1

Some claim "Dynamic" Contrast Ratio of 8000:1 or even 15000:1

In the shop, I can't tell much difference in picture blackness/contrast between the two, although I would expect the 15000:1 to perform much better than 1200:1

Are we being conned by marketing-speak?:rolleyes:

How to compare the two (on paper) and why the seemingly different metrics?

Cheers in advance:)

    There's no industry set standard for measuring contrast ratio.

    Go for it with your eyes, not with the numbers...

    contrast ratio measurment is the difference betweenlight and dark on a screen. dymamic contrast is a measurement based on VESA standard. DC changes according to brightness on scene; ie bright pic=backlight brightness is high, dark picture= backlight brightness is low. this improves the contrast ratio of the picture
