Umm...I believe that's wrong. Your eyes can detect shades of bright up to about 4000cd/m^2, and dark shades far below 1cd/m^2. For two very close things, there is some "bloom" in your eye such that very bright things make nearby less bright things look as dark as can be....but on opposite edges of a big-screen TV, you can definitely distinguish between a larger range than just 4000:1.

Some panels "cheat" by detecting a mostly-dark image, then dimming the backlight, then turning up the backlight on a mostly-white image. So you can take two identical LCD panelsk, one with this 'feature' and one without, and end up with a huge contrast ratio...

(This can be annoying since you may wish to turn up the brightness during dark scenes to well, see them...)

]]> <![CDATA[Forget Screen Size: It's Contrast That Matters]]> contrast ratio is a myth. After 4000:1, it doesn't matter. your eyes can't preceive it.
(How can you use a digital camera to image this anyway? the colour is off and resolution as well)

However, LEDs and LASER tech is better than than fluorescent backlighting...it has a wider colour gamut.

So where is the SED grail?

]]> <![CDATA[Forget Screen Size: It's Contrast That Matters]]> The best I can tell from the giz post is that LG is using an array of LED's as the backlight for uniformity, while Samsung goes one step further and does some image pre-processing to selectively dim/brighten individual LED's in an array to enhance the picture...thus, the 100,000:1 accounts for pixel and LED performance combined.


For more info on this, check out Brightside Technology. For a further explanation, check out the review at Bit-tech.

I think Samsung must be starting to license Brightside's technology. This stuff is waaaay better than a simple "dynamic" backlight with a single bulb. The single bulb only helps for uniformly bright/dim scenes...with the array of LED's that can individually dim, you can have super-bright whites and super dark darks all one one screen. The LED's are placed close enough together that they are within the region that the "bloom" of your eye would alter anyway.

Also, that "100,000:1" is probably the difference between the "dimmest ON setting" of the LED's and the brightest setting. At least in the Brightside prototypes, the LED's can be turned all the way off, yielding what is technically an infinite contrast ratio...they just use the dimmest ON setting so they can provide a logical number.

I mean surround sound is cool and all. But for most applications a tv with nice stereo speakers built into the LCD/Plasma would make me a happy boy.

]]> <![CDATA[Forget Screen Size: It's Contrast That Matters]]> CR is a valuable tool when comparing TVs from the same manufacturer. The older 32" Samsung in my rec room is a 1500:1, but the 40" in my living room is 4000:1. This difference is so noticeable that I try to only use it while playing the xbox360 (unless the Wife wants to watch some Lifetime show - then I'll deal with the older one ;)

]]> <![CDATA[Forget Screen Size: It's Contrast That Matters]]> 100 million:1 that I would still be in the room half way through Joe getting anything outta his ass.

Ditto to the Thanks for not another iPhone post.

FurySting

]]> <![CDATA[Forget Screen Size: It's Contrast That Matters]]> Justsayyes is correct. I could pull 10million:1 out of my ass and slap it on a television, and people would say 'Sweet Jesus that's my next TV!'

It's all marketing, they have no standards or regulations to adhere to.

]]> <![CDATA[Forget Screen Size: It's Contrast That Matters]]> Contrast ratio comparisons only matter after ANSI calibration of the picture. Otherwise, CR figures are just specsmanship used to confuse people.

]]> <![CDATA[Forget Screen Size: It's Contrast That Matters]]> the future of say, the EST? :P

anyhow, my god is that an awesome comparison shot between 1200:1 and 3000:1. i hope they haven't fiddled with the contrast on one of the two

*grin*

This yields a contrast ratio of 100,000 to 1, they say.

i didn't catch the 1,000,000:1 bragging quote. 10x damn for that one.

did you forget the 3 extra 0's or were you talking about the LG?

100,000:1. damn.
