    We all know how difficult is to get real contrast of over 800:1 on
    LCD TVS. Though Samsung are quoting Dynamic Contrast Ratios
    of 3000:1 and 5000:1. Though, when viewing these sets it is really
    not more than a 1000:1 contrast screen. :confused:

    Any help on this matter?? :lesson:

    Cheerz :hiya:

    I've not seen it in action but I understand that they automatically adjust the backlight in order to enchance the contrast ratio...so for a pure black image I guess they turn the backlight down real low and then for a pure white image they ramp it up to the max...what impact this has on PQ I don't know nor wether you can visually notice that the backlight is constantly changing.

    All these figures need to be taken with a pinch of salt though and no one standard is used to take measurements and they are more of a marketing tool than anything.

    I hope to see the new 61 series Sammy next week when my local Sevenoaks gets their demo model in.

    Cheers, Lee

    It's like the 'blackstretch' feature on toshibas tvs - basically the TV adjusts the levels, so it makes the darks darker and lights brighter, so the difference between the darkest and the lightest is magnified somewhat.

    It's a neat trick but sometimes you might prefer not to use it. It's called Dynamic Contrast on the Samsung and can be switched on/off in the menu.
