Source: Chicago Tribune According to Apple, all Macs are capable of displaying millions of colours. However, notebook and iMac have panels which can only show 262000. In order to achieve the appearance of millions of colours, Apple uses dithering, which mixes several colors to give the illusion of more. The vast majority of the public will not see the difference, unless they go specifically out of their way to see the shortcomings of dithering. Last May, two photographers attempted to launch a class action claiming the specifications of the machines in question were false. They decided to withdraw their complaint because it has not garnered enough suitors, but perhaps an amicable settlement with Apple helped. We know nothing about this agreement, and especially the amount obtained by photographers, but it has certainly not been enormous, given that the outcome of the suit was still uncertain and more in favour of Apple. However, it would be desirable that in the future, for the sake of clarity Apple shows the actual specifications of its panels. This would avoid bad surprises, for example, for customers who bought an Aluminium 20" iMac 20 and found out later that the quality of its panel is lower than that of previous (white) models. But as defenders say Apple could not be asked for price cuts at the entry level while mainitaining exceptional quality at the same time. [translation by jeremy]
