    the 17" MBP display doesn't seem as bright to me as the 15" but I'm quite happy with that since viewing angles are better and brightness doesn't shift as much. I have a feeling that it's the brightness enhancing filter that makes the 15" so controversial by directing all the brightness toward the middle and front of the display so that any movement of the user to the sides or up/down immediately distorts the image in one way or another. The 17", on the other hand doesn't do that to the same degree. It doesn't hav a great viewing angle, but it's perfectly acceptable in my book. Unlike the 15" I had which I couldn't find a optimum viewing angle when placed on my lap or on a desk near the edge when I was sitting close, the 17 doesn't get in my way, and I'm usually able to view the display at optimum angle, despite the limited hinge tilt. I also just noticed that the 17" display surface feels softer than the 15" more like what I used to see in the powerbooks. When you touch it with little pressure there is immediate distortion, whereas with the 15" you needed more pressure and it seemed harder - the filter?

    I don't know much about brightness enhancing filters, but judging by the quality of the the two displays and their relative brightness I suspect that the filter is one of the main culprits in producing 'grain' and poor viewing angles. Anybody with more knowledge?

    Interesting.
    It was reported couple of times that the MBP display problem is related to the coating or this brightness enhancing filter.. Viewing angles on my MCB C2D 15'' are just terrible.. the constant need of moving my head aroud to get a decent, even view is simply killing me.

    My question is - how exactly this screen is build? Is it possible to change the coating without changing the whole screen? Are this things separate?

    I will gladly trade brightness away for no grain and better viewing angles. Like who cares? I always run my brightness at 50% anyway.

    My thoughts exactly... I never use 100% brightnes. Do you now how MBP screen is build?

    I seem to remember reading somewhere a long time ago that the film is just attached to the surface, but I could be wrong. who knows, the problem might be that the display manufacturer is purchasing low quality films from somebody or perhaps this is just the nature of all BEFs?

    Given how my 17" looks (no grain, matte and not as huge shifts in brightness when moving my head), I don't think it's the anti-reflective coating that causes the grain and viewing angles. And since you can see that the grain is still when you move a white surface it would indicate the layer that is causing trouble is further toward the surface. it's either the anitreflective coating or the BEF...

    I wonder what they used in MBPs - we dont have "wider viewing angle"- thats for sure..

    I found this on maccnn forum:
    So what exactly is the reason of so bad viewing angles? The type of antireflective coating?

    Well, that's it. The macbook doesn't seem to have a brightness enhancing film and nor does the 17", or it's a weaker one. They all have anti-reflective coating i think. Both the macbook and 17" are slightly less bright than the 15" which, together with better viewing angles, would indicate that they don't have BEFs, or that they are using better quality/lower strength ones? I'm definitely not an expert, but it just seems like the problem is with the way the brightness is manipulated artificially. even when the display looks ok, there's something 'off' with it that I haven't noticed with other displays, including the macbook and MBP 17".

    I think all this stems from the fact that people see brightness and think it is a better display.

    Studies have repeatedly shown that no matter the actual picture quality, people perceive the brightest display as the best one, such as when buying TVs. Hence the reason all the TVs in a store are on "torch" mode, with the brightness all the way up. I guess Apple jumped on this bandwagon, but should have known better, especially on their pro line, which should not be targeted toward the average consumer (but I think Apple wanted to).

    Brightness, viewing angle

    I had a 17" last-generation PBK, and found the screen to dim. My new C2D 17" MBP is much brighter and, for me, much more usable. I'd rather have a brighter screen than one with a wider viewing angle. I think that the MBP screens must take much less power than the Cinema displays, which are plugged in. If you think about it, the screen will be brighter with less power if the viewing angle is less, since the light can all be concentrated in a narrower angle. It's a trade-off -- brightness vs. viewing angle. Obviously, you can't please everyone -- Apple has made its own choice, and I'm happy with it, though I can see why others might not be. Too bad you can't adjust it (brightness vs. viewing angle).

    You're happy with it because the 17" is pretty good compared to the 15"....

    Get a 15" and try saying the same...

    i don't think the problem is only to do with this brightness enhancer you all are talkign about. I am returning my MBP 17" for a refund and gong to wait a couple months and hopefully the issue will be resolved by then. the uneven illumination isn't very uniform, meaning it's not due to a viewing angle. i have a bright spot going down the center slightly to the right. a darker spot in the upper right hand corner and the lower right hand corner. a bright spot running horizontally down the bottom of the screen and right above it is a dark spot running horizontally across the screen. so, there's something up...is it software? hardware of the display itself (my guess)? or some kind of filter? i don't know and there have been some different theories here.

    Does Apple know about this? do peole think they are working to resolve this? I surely hope so. i am sending in for a refund but hope to repurchase in a couple of months. APPLE! FIX THE PROBLEM!!!

    if not, i may settle for an iMac though i really want a laptop. as a graphic/video artist, this display (pseudo)quality is unacceptable!

    so the problem is not an easy fix n my opinon and they rushed these Core 2 Duo computers for the holiday season. i was looking at the display on a 17" PC laptop that is like 4 years old, and it's much better...perfect for a laptop.

    I know this sounds corny, but I suggest everyone who is bothered by this to drop by Apple's website and send them feedback through the Macbook Pro feedback form.

    slightly confused here... if its true - what about terrible glossy screens?

    Done.. but are you sure that it will have any effects?

    The other thing is - is it possible to change the MBP C2D Display? Can I just complain to Apple and ask for fitting a new LCD? Does enyone did anything like this before?

    A 120Gb 7200rpm HDD doesn't exist as a custom option (at least not in the UK): a 100Gb 7200rpm does exist as a custom option on the 17" only. Kind of makes the rest of the report a bit suspect, doesn't it?

    Looks like mistake.. Its just a rumor - but there is a loads of users who are unhappy with their displays so hopefully someone in Apple will notice it. What I dont understand why rumor says that only matte screens are affected? I have a glossy one and things like viewing angles are worst that on crappy Dell display Im using at work. Is there any kind of explanation apart from Apple trying to use cheap displays? Im annoyed and really hope that there will be something "official" soon...
    anyway - even if this rumor is not true - its good to know that there are fed up users who are trying to do something about their issues.

    Did you notice that Apple ppl deleted long thread about quality of MBP displays on Apple forum?
