LCD backlighting - this is what it looks like

I've used CRT's and LCD's. Both of them need some tinting on the front glass to assist with the black levels. Not sure why you guys are making a big fuss about the backlight. It seems simple to me, if you don't like it - don't use them. Some of us use them because of the sharper picture or for any number of space/size/heat issues.

I decranked, not cranked ;)

While this is true, what is important to note is not so much the contrast, but the black levels.  If the brights are very bright and the blacks are washed out no matter how much you adjust the display, it makes perfect sense to use tinted glass.  The difference in the image will be considerable.

While the contrast levels remain constant, richer blacks and still very acceptable image brightness will result from the darker glass.  Very much the same benefits that are achieved when using a tinted window with a CRT

Yeah, I know, but then it is even better to have an ambient light sensor. My LCD is black in a dark room, but is also very bright with deep black at daytime. The backlight adjusts to circumstances. If you use tinted glass, you also limit output when you have much ambient light. OK maybe when it is in the basement, but here it is in the living room surround by many windows.

No misinformation. I posted an example of something that in that case looked the same as LCDs so people would have an UNFAMILIAR example that would actually allow them to understand what they weren't seeing when looking at pictures of LCDs, or LCDs up close for that matter. They simply didn't understand the concept, otherwise.

Incidentally, this post isn't at all about 'authenticity'. It's just illuminating (hah) a certain phenomenon. As for my preference, I like that deep black behind things; or that rich contrast. For that matter, that's why I like 15khz displays, because the luminosity is so brilliant in a way others just aren't and can't be. But that's getting off-topic a little.

@Blanka: variable backlighting, eh?  Sounds neat.
