Hello,

I have recently recognized something that has kinda worried me about my MacBook Pro. The computer is about 2 months old, I've got the anti-glare screen, and there seems to be an issue with uneven backlighting. Looks very similar to this:

And reminds a bit of this (please bear in mind that this is an extreme example of the problem and it might actually not be related to my issue anyhow - the picture below supposedly related to half of the lights not turning on, visually it resembles my issue a bit, though):

http://www.geekinheels.com/storage/thumbnails/2575419-1960909-thumbnail.jpg

Although in my case it's only with the dark background and the brighter areas are visible - they do not stand out greatly though, but are noticeable nonetheless, after close inspection. There are visible vertical stripes emerging from the bottom of the screen, and they have a bit of, I'd say, funnel-shape that is tapering. What is interesting, is that these seem to be noticeable:

• only when there dark colors are dominant on the display (the darker the colors are, the more noticeable the "effect" is)
• only in pure darkness, e.g. in a dark room, where the MacBook is the only source of light (apart from the keyboard)

Not sure if it's a "problem" with the display, as other than that it works and worked a-OK, and I haven't had any other problems with it so far - so it might as well be just a "feature", rather than a "malfunction" of any kind, that I have not noticed up until today.

As I said - it appears to be noticeable only when it is totally dark around - but it is a bit frustrating still, when e.g. watching movies/TV series that have mattes (black bars) above and below the image.

Should I be worried about this, or is what I have described a perfectly normal situation with a healthy MacBook Pro display?

Many thanks,

Dynamitri

    Contact Apple and get it serviced. You could even have a graphics circuit issue there, as the problem does sound hardware-related.

    Thanks for a quick reply. To be honest, I'd rather it was not eligible for being serviced - would love it to be just a general feature of the screens (some of the threads on the Apple Support Discussions Board seem to mention that it might be a general issue). That would be really soothing for me, as I have a bit of an OCD when it comes to my equipment. With it being a perfectly normal behavior of an antiglare screen on full brightness settings, in a dark environment, while displaying pitch black color, I could just take it for granted and live with it - and possibly forget about it in a few days'/weeks' time. Otherwise I know that it's gonna keep bugging me until I do something with it - but I can't be left MB-less for job-related reasons, so it's a bit of a limbo for me.

    Anyway - a thread that features a post suggesting it might be just a generic issue with all the displays can be found here:

    http://discussions.apple.com/thread.jspa?threadID=1923032&start=15&tstart=0

    (first post at the bottom of the page, by eplugplay)

    "That looks pretty normal to me. Every single lcd has backlight bleeding/uneveness to some degree when its on full black background in the dark.

    When in normal usage you hardly ever see it though.
    "

    This is a 4-months-old thread, though, and the post seems to come from an unexperienced user (postcount of just 21), so I have no idea how reliable and trustworthy (s)he is, as far as opinions like this are concerned.

    I already am on my fourth MacBook Pro now (third replacement, each one of them for different reasons), since my initial purchase mid-March this year - so you will appreciate the weariness that I already feel, and my reluctance to parting with my MacBook, considering the type of work I do.

    I would therefore be very thankful if someone could please elaborate on the issue, maybe check their own screens with similar settings of both the display and the environment around? Any kind of constructive feedback regarding the case would make me feel really indebted.

    I have an appointment with a Genius on Tuesday for a keyboard replacement (got several slanted keys). I will be left without my MacBook for approximately 20h (yeah, that's "twenty hours"), and it has already caused a lot of job-related distress for me. See - I work as a freelance journalist, my MB is the only computer I have, and it is essential for me to work on my MB - my job is totally on-line and computer based, and requires 24/7 Internet connection and access to a computer.
    Why am I mentioning it? Well - I might be wrong, but I presume that "having it serviced (for the supposed 'uneven backlighting')", would boil down to me being left without the computer (again) - but, this time, for more than 24 hours. And that is - unfortunately - unacceptable in my case.

    Before I get into a nightmare of being MacBook-less for several days (if I will at all, that is), I would prefer being 250% positive about all this being a service-worthy issue. I'm pretty sure Apple will be happy to replace the screen or do whatever to please me, 'cause they're an amazing company - but, in all fairness, if it's not necessary and my reservations are not actual "problems"/"faults" per se, I'd rather keep it as it is. I only can consider parting with the machine again if it's gonna be absolutely necessary - therefore I have to be confirmed in that it actually needs being fixed.

    Many thanks,

    Dynamitri

    I was in that boat a few months back. I went and bought a used MacBook Air for a backup. I don't want to go through that again. You should do the same--even if it's a cheap iBook or PowerBook. Something that gets you online and does word processing.

    I can assure you that if I only had the funds I would have done it already. Unfortunately, having forked out the equivalent of $3'700 (£2'200) on my MacBook Pro four and a half months ago, I am - unfortunately - unable to make additional spendings of this type, at the time being.

    Thanks for your input though, it is appreciated. If someone could please provide me with some constructive feedback regarding my case, I would be really thankful for that. Every bit of information regarding the issue will be highly valued.

    Many thanks,

    Thought I'll add this, as it seems I forgot to mention this earlier on. I am experiencing these issues with:

    • full brightness settings on (the brightness/backlights are set to maximum)
    • automatic brightness adjusting according to ambience light turned off

    With non-maximum brightness and/or auto-adjust turned on, the "effect" does not seem to appear. Or - at least - is not noticeable.

    Many thanks for help.

    Best,

    same problem here!

    http://img3.imageshack.us/img3/4176/imagetl.png

    picture is from my second display unit. had another one before which was very similar, if not a little bit better. got replaced at genius bar.

    light bleeding is worse when machine heats up.

    I will get my third display soon an will report back.

    I also noticed that thelcd panel is misplaced in the display unit, so that I have a black border between the actual panel and the metal frame on the right and at the bottom.

    very disappointing! bought the top of the line "pro" model since i need it for business...
    seems like a non-pro quality control....

    This jpg of your screen (the first your listed on this thread) looks perfectly normal to me. My guess is you will spend the rest of your life replacing LCDs trying to get a better one.
