    We've seen two different brands of screens being used so far. How to find your model.

    • 9C79 (Samsung LTN170CT)
    • 9C7A (LG-Philips LP171WU4-TLA1)

    Hardware calibrated ICC profiles

    If you are used to incorrect colors, switching to more "correct" colors can look strange. It may take a day or so to adjust to any color change.

    Samsung 9C79
    • rez Sypder2PRO (Backlight at +8 squares, gamma 2.2 at 6500K)

    LG-Philips 9C7A

    1. What model is it? (search if you don't know how to find this out)
      Model: 9C79
    2. How even is the backlighting?
      Backlighting is SWEET! It's very bright and colors are outstanding compared to my older Asus laptop that I'm replacing. It's so bright, in fact, that at it's highest setting I can't look at the screen because it gives me a headache (I am slightly sensitive to light). No screen has ever done that to me. Oh, and not to mention the sick resolution this baby gives out.
    3. Any yellowing or other color shifts?
      Nope, none -- everything is presto!
    4. How's the viewing angle compared to your old CCFL 15" or 17" screen?
      Fantastic! I can view it almost from the side and still have the colors look about the same.
    5. Overall impressions and anything you think could be better?
      The screen and display are top notch and I couldn't be happier. The laptop in general gets a bit hot on my lap though and that's my only complaint thus far (I don't own a desk as I don't have room). I may have a bad machine, please everyone else let me/us know the temperature your 17"ers are giving out when you get them. I'm happy to be the first one to reply to this thread. :D

    download SwitchResX, open its system preferences panel and export the DDC file. At the bottom of the DDC text, it will tell you the LCD model number which can then be googled.

    1: 9C79
    2: Good, very bright.
    3: Nope
    4: Looks good from all angles I use regularly on the laptop
    5: Too early to tell and little to directly compare with yet.

    Model # is: LTN170CT which is a Samsung display.

    2. Backlighting is even as far as I can tell. Screen is really bright.
    3. Didn't notice any yellowing.
    4. Viewing angle I think is about the same as my Powerbook 1.33Ghz 17", but I haven't done any definite tests.
    5. Yes the screen can be better. It seems LED backlighting is being implemented where its strips of light going up behind the LCD. What I would like to see is an LED array, like the Brightside Technology displays, behind the LCD. Of course this won't happen for sometime, but it would be nice in laptops now. :D

    Ditto for everything except the headaches and heat issue. It gets warm, but less than the pre-Penryn MBPs. I'm extremely happy I went with the LCD-backlit screen.

    Thanks for the replies so far! I have updated the first post with some of this info.

    Mine is still stuck in China :( so it will probably be another week before I can calibrate. If anyone has already done so (preferably with a hardware profiler) feel free to post the ICC file and I will link to them in the first post.

    The heat is perfectly normal. Macbooks (of all varieties) are not laptops. They are classed as notebooks and as such are designed to be used on a hard surface.

    Added link for tech specs in the OP. (And wow, google works fast - searching for the screen part # already brings up this thread in the first page of results!)

    Keep the input coming. Someone has to find something wrong with these things. ;)

    Hey guys, I'm joining this thread!

    After having ordered a 17'' HR GLOSSY and waiting 2 weeks only to realize I'd have to wait almost 4 more, I changed my order to a MATTE screen that should be here in 2 weeks!!

    If only I knew this I'd have ordered the MATTE in the first place... BAD Apple! :(

    EDIT: Changed the order to a Matte... Getting here within aprox 2 weeks :/ (still better than the 4 for the glossy!)

    Hi all! I'm a long time lurker, first time poster. Just thought I'd contribute to this screen thread when I came across it looking for information on the screen on my new Penryn MBP.

    Just received my MBP a few hours ago, just finished partitioning the drive. This machine is a replacement for a last revision Merom MBP with a Hi-Res screen.

    So to answer your questions:

    1. Model::9C79

    2. Backlighting evenness:: Good.
    (Brighter and more even than my previous Merom MBP)

    3. Yellowing and colour shifts:: Yes and slight
    (See below as to why I'm so wary of these issues)

    4. Viewing angle:: Better than my previous Merom MBP
    (But colour shifts to yellow --> Magenta when I shift side to side. Better than my Merom MBP, but not as good as my PBG4 1.33GHz)

    5. Overall impressions + improvements:: Nothing significant. The build quality is slightly improved from the previous revision. I wish I could get the old keyboard back. No num-lock on the Penryn is going to make entering data in Excel a slight PITA.

    So the back story...

    Basically, I had a run of bad luck with screens on my previous MBP. The original had a misaligned LCD and a little bit of colour shifting. The next screen had a red band horizontally across the screen, and a little red square blob under the line. The 3rd screen had an issue with the inverter and 2 dead pixels. The final screen had a very obvious yellow tint on the TOP third of the screen. After the 4th replacement, Apple CRU contacted me and offered this Penryn MBP as a replacement. As you can imagine, I was a bit apprehensive about getting a replacement system, but reading the extensive "AnandTech" review (mainly about the transition from a TN display to a IPN one) helped me decide to take Apple up on their offer.

    So cue forward to this point after waiting for 8 (working) days. I open up box, boot up, go through my ritual of partitioning and general setting up, and check the screen, and lo-and-behold... Yellowing on the TOP third of the screen, and a yellowish/ magenta patch on the upper righthand of this panel slightly bigger than my iPod. This patch "disappears" as I move the screen left though, but it's definitely there when I'm centered to the screen. I've tried to tweak the colour profiles through the Apple calibrator, but all I've managed to do is to the turn the bottom part third of the screen bluish, not to mention somewhat washed out colours.

    I think I'm going to try to live with it. But as a graphic designer and photographer, I am fairly sensitive to colour shifts as these phenomena could affect my work.

    I'll keep you all posted on what I decide. But in the meantime, any suggestions?

    It seems the downfall to any apple portable is the screen. Don't know why. Been through 4 on my MBP, and I still have problems with this one. Even backlighting please?

    Well, I'm "glad" to hear that I'm not an isolated case here. But how is the screen on your SR MBP?

    It's morning now in Singapore, and I'm still looking at the screen. Bright surroundings somehow minimise the yellow tint and the colour shift patch, but it's still noticeable. But then it could be the "placebo effect". I'll check again later tonight.

    Off note, I've expressed my concerns about Apple's build quality and quality control to the Apple CRU here in Singapore. I've had several older portables, my Tibook G4 1GHz and PBG4 1.33GHz had great screens and good build quality, and they still do. I think Apple is starting to realise that we're not going to stand for sub-par experience on an expensive portable, since they've replaced my previous Merom MBP. The service has been sterling for me, but then the disruption to my work and the time spent waiting for service and courier collections and deliveries do take a toll. I sincerely wish that quality standards would return to the Apple portable range.

    That my opinion. I'm sure there are people who'd agree and others that would disagree with what I'm saying. Just go easy on me, huh.

    Thanks Nicholas, I too have quite a history of bad screens with Apple. My incoming Penryn MBP is a replacement for my 2nd gen MBP which is a replacement for my 1st gen MBP. All had issues (among others) where the left side of the backlight began to get noticeably dimmer than the right side after 4-5 months. (This makes me question my environment, but the fact is there's been a Compaq notebook in the same room that has had no issues for 2+ years).

    Your sentiments echo what others have said, which is that the viewing angle on newer notebook LCDs is not as good as older ones (like on the Powerbooks). I really don't know the technical reasons for this, but I suspect the plummeting prices of LCD panels don't help.

    Hang tight, because in my experience the default color profile that Apple ships with their notebooks is pretty far off and always has a strong yellow shift in my experience. This will definitely exacerbate the kind of color shifts you are seeing. So when we get some calibrated color profiles in this thread I bet you'll see improvement.

    However, if the color shift bothers you now, do not hesitate to get a replacement from Apple, as they need to know about issues like this, and that magical 14-day replacement period goes fast!

    I couldn't agree more, actually, as I've had numerous problems with MacBook Pros ever since they were first released. More often than not, the problems were with the screens, but I've been one of those few but very unfortunate ones who have experienced just about every documented MBP defect since 2006.

    What bothers me most is that none of my other Apple products have ever had any problems. I've been through three Intel iMacs, a Mac mini, two MacBooks, an iPhone, Apple TV, AEBS, and various iPods. I still have most of these products and they have worked flawlessly from day one. It seems like the more expensive an Apple product is, though, the more likely it is to experience quality issues.

    pretty much the same thing for me. i was wondering if anyone had a good color profile for the LED 17". I know there are other threads out there but none are about the LED version of the 17". Should i just use one from those threads or is there a custom one for this display?

    To my knowledge no one with these screens has a colorimeter. I'll be getting mine next week and will post some color profiles made from a Spyder2 PRO.

    A little off topic here, but same here. Above the TiBook G4 and the PBG4, I also own a Mini 1.83 CD (I bought for my parents' as an anniversary present) and an 20" iMac 2.4GHz C2D (for my agency's admin and light workstation), and they've been real workhorses, nary a problem (knock on wood).

    In addition, I've owned and used almost every Mac. From the Macintosh SE to the PowerMac G5 Dual 2.5GHz. I've not had any major issues with any of them, except for one of my three IIfx's.

    I must say I'm disappointed with the problems with QC Apple is experiencing with their portables of late. I don't want this thread to turn into a rant for QC issues, as I've noticed a whole slew of extensive threads discussing these issues.

    So I'm on the phone to AppleCare, waiting for a CR rep to take my call.

    I've run SwitchResX on this MBP, and here are the results.

    Edit: Just got off the phone with AppleCare, and the CR rep wants me to take the unit to a service provider to be diagnosed and repaired. The technician with the service provider thinks I should insist on a replacement since it was only delivered yesterday. I'll try to contact the CR rep who offered the Penryn for Merom replacement to see if I can get some consensus here.
