Yeah, and they don't want to tell him. So... He can either A) do a google search (which indicates that yes, the 15" does have 8-bit color) or B) Give up on Apple and get a different brand/OS

Sadly no, MBP15 has also 6-bit TN display.

Can you back up this assertion? Since one person in this topic already said that the 15 inch model does have 8bit and you just say that it doesn't, how am I supposed to believe you?

Define pro.

I dunno, "pro" for a graphic artist probably includes "actually displaying millions of colors instead of dithering so I can actually tell what color it is."

Exactly: it's something people make up on the spot to justify whatever complaint they have with a "pro" product.

Interesting. The Apple MacBook Pro website makes no distinction between the models as to the color support. They all say "millions of colors", and as someone who doesn't deal with colors for a living I would expect them to have identical support.

Technically, a 6-bit display can display all of the same colors that an 8-bit display can. What it can't do is display all of them at the same time . Edit: Why all the drive-by downvoting? This is true to the best of my knowledge.

I remember 16 color systems that could load different palettes of 16 colors each, too. Doesn't make it a >16 color system.

Alternate headline choice: Man with ability to research decides not to and is disappointed in purchase but offered full refund

That's not entirely fair. The specific information he was looking for is not made available to the public by Apple. He was only able to find the information after getting the model number for the display and checking with the vendor. There was no way of knowing exactly which display was used without access to a MacBook Pro because that's not information made public by Apple, either. It's an awfully roundabout way of…

they're clearly skimping on parts

This is not clear at all. Every manufacturer uses 6-bit displays, even in most if not all high-end models. This has been true for years. They choose to do so because such displays have desirable properties other than color, such as price and lower response times.

>>It's called a MacBook Pro and is marketed at more demanding users, i.e. professionals Which "professionals"? 8bit color is important to pretty much one professional group: graphic artists/designers (maybe two, if you include people doing video work). For the vast majority of people - "professional" or otherwise - 6bit vs. 8bit color doesn't matter. It looks good, it's fast, it runs what they want. Those are the thi…

At the minimum, it's faulty marketing on Apple's product. They shouldn't state that it supports millions of colors when it actually doesn't. Just like the CRT monitors that are 17" but only 15" viewable... sometimes that stuff doesn't change until someone files a lawsuit.

I didn't say they were the same thing, or that 6-bit displays were not 6-bit displays.

Without dithering, 6 bit LCDs produce 191 colors. 8 bit LCDs produce 767 colors. If you want more than 767 colors you will be using dithering.

I think where people get confused here is the naive dithering where a group of 3 pixels (one of each color) are logically grouped together gives your the 252k and 16m numbers, but there is no reason that is the only desirable solution.

Consider sub-pixel rendering of typography. This abandons the traditional groups of 3 pixels and uses alternatives to gain better horizontal spatial resolution. Consider a white, lowercase 'L'. Depending where it appears on my screen it could either be a single white pixel under the naive "groups of three" dithering, or a yellow pixel next to a blue pixel. The catch is that unless I show you the borders of the screen you can't tell which it is.

Fortunately, I have a brand new 15" MacBook Pro under my fingers. Tonight when it gets dark I'll take a picture of a gradient, enlarge it beyond the capabilities of my eyes, and we will have an answer about what Apple does.
