Re:How can you judge colour quality? (Score 3, Informative)

Most people dont realize (hell, nobody does) that 6 bit panels (as opposed to 8 bit panels) do not lose the 2 MSB; they lose the 2 LSB. As a result,instead of the LSB being a digial 1, it's valued at a digital 4. They are fully capable of displaying the full 24 bit color palette, but they have problems when the image is very dark. To illustrate the point, when the image is Full White (R,G,B=255,255,255) with an 8 bit panel you may see the signal swing from 254-255. On a 6bit panel the signal will swing from 251-255 since the LSB is now 4. You will only notice this on certain shades of grey, and you will need to be looking for this effect since the issue is very subtle to begin with, and then its very hard to notice unless somebody knows EXACTLY what you are seeing. Apple just went from a PVA panel (better viewing angle (180), better contrast (1000:1), crappy response (8ms) ) to a TN panel (average viewing angle (165), average contrast (700:1), but awesome response (2-3ms)). Nothing to see, move on.
