Until you've experienced an EIZO FlexScan LCD firsthand, you have no clue ;)

Actually my argument was based on the false notion that 2000:1 CR plasmas offered better image quality than an LCD with a CR of less than 800:1 and the false notion that LCDs can't compete with plasmas because of light leakage etc. due to their technology. Those blanket statements are totally false with little to back it up. Read a couple of reviews on the EIZO FlexScans or see one for yourself. Until then everything that's been said are just assumptions. The EIZO prove that a good LCD can beat plasmas. BTW I've never been to any theater where the audience gets blinded by a bright white light from a scene in a film and that's the way I like my display to behave at home. Put a properly calibrated EIZO next to a properly calibrated plasma and they will look very similar. If you want to be blinded by your display then maybe you should build your own with a 10K watt bulb? Too much contrast and the image just looks degraded and unrealistic, that's why they made calibrations software. Watching DVDs on your laptop isn't an accurate measure of what LCD technology is capable of. Lastly as Democoder said a theater's projected image only has a CR in the hundreds to 1 yet it has high dynamic range therefore allowing you to see shadow detail. That right there contradicts what he said initially about CR being the defacto spec that allows plasmas to stand and LCDs to fall...


BTW nondiscript how many shades of grey can you see below? Where does one end and one start??? ;)

The reason why I brought up 24-bit color is that the human eye cannot resolve more than 256 shades of any single color. Even though black and white are not colors they still follow the same principle, therfore a 256 greyscale bar from black to white is the maximum range the human eye can detect. However the typical person can only differentiate between 50 shades of grey or 50 levels of brightness. A LCD with a CR of 1000:1 can easily resolve a 50 shade greyscale bar. As a matter of fact, medical use greyscale LCDs can display 1024 shades of grey simultaneously.

If you're saying that you don't WANT higher contrast and more colors, fine, I can't argue with what you do or don't want. But, that's quite different from saying that your eyes can't tell the difference. My point was to show that your eyes can tell the difference.
 
Above there are three greyscale bars. Look at the original bar and tell me where one shade starts and one ends.

If you have a light bulb in a dark room and adjusted the bulb's brightness with a 256 step dimmer switch, do you think you can see the difference between step 255 and step 256???

Your image is a JPeg - around ~3000 colors per bar and no vertical shades - only dispersed pixels.

Your question as such is pointles - but if you insist, it's quite easy to see where one pixel starts and another ends under magnification. :p

I guess you were aware it was a trick question :LOL:

Sigh, PC-Engine, you just don't understand light, color, and film. Do you know the difference between a print and a negative? Film makers will generally use film that has a ratio of about 7 stops, or 2^7 = 128 or about a CR of 100:1 (in reality, it's more like 400:1) They will use this to film a movie where scenes vary over a 10000:1 ratio, by of course, adjusting lens aperture, exposure, and lighting. Day scenes, night scenes. They will use differing film with differing sensitivies depending on the scene (slow vs fast, etc)

The result is a movie that has a huge contrast range. This movie is then PRINTED onto Color Print Film, which typically has a CR of 1:5000 to 1:10000 (Kodak Vision = OVER 10000:1)

Now, depending how how shitty your theatre is, with regard to it's ambient light, bad paint job (reflected light), and crappy screen or projector box, this will be reduced, but original film prints certainly have a CR of over your crappy LCD.


The fact is, when a scene is CAPTURED, you have to deal with limited film speed (it is, after all, a MOVE-y) which limits your grain and density, but that's ok, because the director can adjust the scene's lighting and exposure to compensate and capture the range needed. But during PRINT, you have complete control over the transfer, and I can transfer a scene at the low-light end of the spectrum, and transfer a scene at the high end of the spectrum, onto the same SLOW high quality PRINT FILM.

Display devices have to have a wider range CR than capture devices for this reason.

You can keep ranting on about your LCD being able to display X different colors all you want. It's completely irrelevent. Perform this test: Display all X different colors on your LCD. Now go and adjust your monitor's brightness and contrast. You now have Y different colors on your screen, and Y != X, opps, I thought your LCD could display all possible colors we could perceive?
