    Grrrr, new £3000 machine has really bad light bleed along the rubber edges of the screen, omn the outside of the black bezel... anyone else experienced this? Kinda annoying as I can get replaced but its a customised machine and only just managed to get it all set up grrrrr.

    I found that bleeding is rare with these 2018's...that is if you meant the latest MBP.

    Mine has no perceivable bleeding at max brightness in a pitch dark room.

    Any photos?

    Actually, turns out there is a tiny bit of bleed! Fire up a solid black screen (search for ‘solid black’ on YouTube, then full-screen it), take it into a pitch black room and turn the brightness all the way up, and you’ll see a few very thin points of light escaping around the bezel on the sides and top edge. Seem to remember this being a thing with the 2016, too. They all did it, so not a fault.

    Still want to see a photo of OP’s ‘really bad’ example, though.

    You're referring to 2017 MBP's which do have backlight bleed problems. The 2018's are different!

    I did all the testing on mine with a pure black screen with the old "iMac Yellow Test Website":
    http://imac.squeaked.com/test.php

    Also, I wouldn't use YouTube as a test for pure black.

    Believe me, when I say there is no "perceivable" light bleed, there is none on mine and the one that it replaced with a slightly creaking chassis.

    Its a fault, even if majority did it, a laptop with this build quality and costs shouldn't have any light bleeding from there edges lol - I am gonna replace, just very annoying as I have to backup again and re install everything an dog course wait for a new machine with the customised specs grrrrr

    How much you wanna bet the replacement will have the same thing? :)

    It's not a fault.
    --- Post Merged, Aug 7, 2018 ---
    We're not testing for pure black – it's just to stop the brightness of the screen itself obscuring the 'bleed' so you can see it. It clearly works, so what's the problem?

    And I'm referring to both the 2016 and 2017 MBPs, both of which have the same non-issue. They all do it to some extent if you check it properly.

    I’m willing to believe we’re talking about two different things here so I will stop debating.

    With that said, the backightlight bleeding I’m referring to is the flashlight-like effect that is seen in the corners of a completely black screen. It seems with the images attached, it’s confused with a “consistently” brighter screen than one that should be pure, dark black. If this is the complaint then yeah, LCD’s have this and unless Apple changes to OLED, we will not get pure blacks.

    And please, stop generalizing the years...have you even owned a 2018?
    --- Post Merged, Aug 7, 2018 ---
    It’s hard to tell from your pictures because you have text/images in the corner that seem to contribute to the brightness. Furthermore, the camera used has exaggerated bleeding and colour shift to pink seen in the centre. I bet this is not what you’re seeing in real life. Post a picture of a completely black screen then lower the exposure level of the camera to match what you’re actually seeing with your naked eye.

    I just tested my 2018 MacBook Pro 13" and can confirm that it does indeed have the light bleed issue pictured by the OP, although less severe. I have not noticed it under normal use though. Just got it a couple of days ago and still testing to see whether I'll keep it or not. I cannot see it indoor during the day even with the screen brightness maxed, which just hurts my eyes. I'll try later tonight and see if it's noticeable in a dark room with an appropriate screen brightness setting (ie. not max). If it's not, then I'll consider it a non-issue. But the OP is right. It's not just his MacBook having this issue and for a product in that price range, it really shouldn't be there even if it's only visible under extreme circumstances.

    For some reason, Macrumors is not letting me attach a link to a picture, but:

    Here is a link to a page that shows a slight backlight bleed in the corners. Mind you, this picture was still not taken with the proper exposure so what you're seeing here is exaggerated, but it shows you what I mean:

    https://forums.imore.com/macbook-pro/394731-backlight-bleed-2017-macbook-pro-touch-bar.html

    Also, please don't confuse this with IPS glow...although it can look similar to it.
    --- Post Merged, Aug 7, 2018 ---
    I would suggest going in a pitch dark room, set the brightness to max and run Test Screen then Pixel Checker, scroll through the colours until the pure black screen from this website...you will need Adobe Flash installed:

    http://imac.squeaked.com/test.php

    Again, your screen will be brighter than your room since it's not a OLED (where each pixel is not lit on pure black), but you're looking for consistency in the screen without any sort of bright patches, clouding or flashlighting. Let us know what you see.

    You don't have to wait until it gets dark...just go in a room with no windows, shut the door and turn the lights off.

    I refuse to crawl in a dark closet and turn the brightness all the way up on a black screen to see this. I have had my MBP for over a week and have not had the first problem with it.

    Get out of the dark closets, folk!

    +++That's not what we're talking about, no. See the little strips of light breaking through the bezel in the pics above.

    +++Er… I'm typing this on the 2018 that replaced my 2016 three weeks ago, yeah. Why so cynical?

    +++As described, it's not the screen we're talking about – it's the backlight shining through the rubber bezel surround slightly.
    --- Post Merged, Aug 7, 2018 ---
    It's not an issue, honestly – I'm totally sure they all have it.
    --- Post Merged, Aug 7, 2018 ---
    This is absolutely NOT the light bleed we're talking about, just in case any newcomers to the thread are wondering what's going on. :)

    Again, mine does not exhibit any backlight issue...and again, do not generalize and be sure they all have it. I am trying to resolve my picture attaching issue here on Macrumors and I will show you mine.

    I've had mine replaced and the first one I had did not exhibit any issues either...nor 3 of my friends'. Believe me, we work with video and photos and the first thing we check is the screen's consistency.

    Loads of Mac book Pros from last year had keyboard issues so it can't have been a fault if so many had it...? Thats basically what you are saying.

    Light bleed IS a fault lmao
    --- Post Merged, Aug 7, 2018 ---
    Ummm Im playing a VERY low res video hence the pink/bad quality image there, the image u are seeing IS what I am seeing, and the white edges are clearly visible lol, how are you not seeing it XD?

    With the brightness turned all the way up, I do not think so.

    A'ight – I was just trying to make you feel better about it. Mine's got it, as did my previous 2016, and it's never bothered me in the slightest.

    (And no, of course that's not what I'm saying – the keyboard issues actually affected the functionality of the machine; this doesn't.)

    Wait, so you are talking about the white light right along the edge of the laptop? Away from the screen?

    At first I thought that was just a reflection... If that is in fact light coming from the laptop away from the screen then yes it is a defect and you should get it replaced.

    I expected to see pictures of LCD backlight bleed, but the pictures from OP show light leaking out past the outside edge of the lid bezel. Not an LCD issue at all, but a mechanical issue where the outside edges of the display assembly is not seated tightly, rather than a light-tight assembly. Perhaps this is a normal manufacturing variance, and likely within specs.
    Yes, I agree about the brightness turned up. Not a likely scenario for the normal user in a dark room!

    Then yes. Everyone else is full of it and looking at the actual screen. That is 100% a defect and should be replaced.

    C'mon man, this is going out of control! Turning it up all the way in a dark room is for checking purposes only...I don't recommend doing it in normal viewing.
