Apple Sued for Deceptive MacBook and MacBook Pro Advertising

Lawsuit claims LCD screens on Apple's current notebooks are not capable of millions of colors
Apple Inc. has been in and out of the courtroom a number of times
this year for patent infringements
mostly to defend its iPhone
. This week, Apple finds itself in the courtroom again, this time facing a class action lawsuit alleging the
LCD screens on its MacBook and MacBook Pro laptops are substandard
. The claim also alleges Apple advertised its screens as being superior, but knowingly shipped screens that did not meet its original claims.
The class action lawsuit points out the glossy screens Apple introduced with the launched of its MacBook last year. Apple advertised that the new glossy screens provided users with deeper blacks and whites that are more vibrant. However, many customers experienced graininess and sparkling effects common to dithering techniques, according to the lawsuit.
According to the complaint:
Many such dissatisfied purchasers were chastised by Apple agents and employees for being too picky about their assessments of the quality of the display. Other dissatisfied purchasers were told that they were imagining the complained about defects.
The complaint also points out that many of the disgruntled customers posted messages on Apple's own forums only later to have their posts moderated or completely removed by Apple forum administrators.
"It appears that Apple has engaged in substantial editing of the posts on the discussion forum," the lawsuit indicates.
The lawsuit alleges Apple uses dithering techniques to create an illusion of colors that don't actually exist. In fact, the lawsuit claims if a MacBook or MacBook Pro users installs Windows XP, they will notice superior image quality in areas such as gradients. The test seems to indicate Apple is using some sort of software at work in OS X.
"The displays are only capable of displaying the illusion of millions of colors through the use of a software technique referred to as 'dithering'," the lawsuit claims.

Many of the posts early in this thread stated clearly what the 6bit & 8bit designations meant.
Since you missed the above
6bit LCD has three colors per display pixel. The numeric value for each of the three colors requires 6 bits. These displays are also designated 18bit displays due to the number of bits required to specify all 3 color values.
8bit LCD has three colors per display pixel. The numeric value for each of the three colors requires 8 bits. These displays are also designated 24bit displays due to the number of bits required to specify all 3 color values.
A rare variant uses a 32b color value & assigns 10bits per color. the remaining 2bits of the color value remain unused.
Video cards may add data for the alpha channel. a 6 bit display for this standard uses a 24 bit color value & the 8 bit display requires 32 bits per display pixel.
The above obviously applies only to LCD displays that use RGB. For Monochrome displays it is usual to convert the RGB value to the 8bit value corresponding to the brightness of the pixel. Or if it is a 6bit monochrome display, the 6bit grayscale value.
Also stated in many posts is that the manufacturers, resellers and OEMs building devices using the LCD parts do not disclose which of the 3 bit levels is used. LCDs supporting the 10bit standard are likely to be the exception as they will be selling into a specialty market that will pay premium prices for 10b hardware.
Simulated 8 or 10 bit per color generates visible artifacts for certain colors. This inaccurate color rendering is visible if any of the problem colors are used. This is why real 8bit has 16.7m colors and simulated 8bit has 16.2m colors. It is also why trained users can see a visible difference in the result.
Now back to the regularly scheduled discussion :)
