New 20" iMac Screens Show 98% Fewer Colors

Trintech writes points us to an AppleInsider article about another class-action lawsuit directed against Apple Inc. This one claims that the displays on new 20" iMacs are only capable of 6-bit-per-pixel color, 98% fewer colors than Apple advertises. Rather than the 8-bit, in-plane switching (IPS) screens used in 24" iMacs and earlier 20" models, "[t]he new 20-inch iMac features a 6-bit twisted nematic film (TN) LCD screen," according to the article, "which the [law] firm claims is the 'least expensive of its type,' sporting a narrower viewing angle than the display of the 24-inch model, less color depth, less color accuracy, and greater susceptibility to washout." Apple recently settled a very similar class-action suit about the displays on MacBook and MacBook Pro models.

No, the article just wasn't clear. It actually means 6-bits per color channel per pixel. In other words, 18-bits per pixel instead of full 24-bits per pixel. And the reduction from 2^24 to 2^18 does indeed reduce the number of colors from about 16 million to 262,144 - a reduction of about 98% of the entire color space.
