Bright Side of News reports Apple is lying to consumers about the specifications of the 13.3" MacBook Pro. The company tricks people into believing the display supports millions of colors, while it actually has a 6-bit LCD panel capable of producing only 262,144 colors. The larger 15.4" and 17" MacBooks don't have this problem, they feature 8-bit LCD panels with support for 16.7 million colors.
According to his story, he decided to sell a 17" MacBook Pro and purchase a brand new 13.3" MacBook Pro sporting nVidia GeForce 9400 graphics, more memory etc. Things started to go awry when sales staff had no idea whenever 13.3" MacBook Pro has the same 6-bit screen as the regular 13.3" MacBook or a "professional", 8-bit spec. Long story short, he was lead to believe that the screen was "upgraded from the 13" MacBook screen, it had a "wider color gamut" so... it must have been?"
Unfortunately for him, after purchasing the wrong DVI adapter [as advised by Apple Store crew], Louie found out that the screen is 6-bit, capable of displaying only 262,144 colors. Just like other notebook makers, they can "cheat" their way of claiming "displaying millions of colors" through dithering, but if you're a designer or working a job which requires you to be precise with colors - you're good as gone.
