Sage, thanks much for the details. I am very well aware of all you said. As I pointed out, I made a choice. I don't have a dedicated room, perhaps 90% of the families don't.
True, without trickery led black will look grey, but that is only in dark, and I never watch in dark. During the day the "grey" black is justs black, since it is so bright in the room. That is called percepted level, very easy to full the human eye, not measuring instruments. I know this limitation, and I live with it.
Be it a trickery [the smart led] as it may, the human eye, as I said previously, is adaptive, think on this for a moment. I turn on an ambient light behind the TV at night, and that makes the "grey" blacks black! I dont use the smart led at all, don't need it.
I don't agree with you, however, that LCD colors are faded out - far from it, in my conditions. On the oposite, I brought a plasma home to test and it had faded colors.
So, can we agree to disagree?
