    Greetings,

    Just bought a new 2017 MacBook Pro 15" (3.1 GHz, Intel HD Graphics 630 & Radeon Pro 560). Happy with the machine so far, display seems fine, and cosmetically all in good condition.

    Was on CNN.com last night and was watching some of their videos. A couple of times, the video screen went green -- this happened at full screen but also reduced video screen size (see attachment). The entire MacBook display didn't distort screen --- it seemed to be limited to the video window.

    It's very much what this YouTube user shows as happening on a 2015 and 2016 MacBook Pro when he watched some YouTube videos (about 34 secs in):



    He claims the issue stopped after he updated Flash. I updated Flash, but it did happen once again sporadically on CNN (not even sure if the CNN videos use Flash).

    Anyway, didn't know if anyone else has seen similar.... maybe it's just a buggy player on CNN. I haven't seen it yet while playing YouTube vids. Or, is there any "test" one might recommend to make sure it's not a bad video card. Here's screen grab of what I saw:

    Thanks for any input!

    To find out if this is the graphics card.

    Make a screenshot and open that file on another machine. If you see the green, then I would say the graphics card is faulty.

    Thanks for reply, but I'm not sure how this approach would be used to evaluate the video card on laptop. The included image in this thread is a screenshot, viewing it on any machine will show the green, since it is a screenshot. Perhaps I am misunderstanding your answer.

    When the green appears, make a screenshot with cmd+shift+3.

    A PNG file will be created on your desktop. Open this image / file on another machine, e.g. a Windows laptop.

    When the screenshot - the file - shows the green - then either your graphics card is damaged, your system is somewhere damaged or the drivers has a bug.

    Yes, I did take a screenshot of the green effect... that's the screenshot I attached to this thread in original post. So since we can see the green here, it would imply a hardware issue with graphics card or driver has a bug

    by the way. I show you an old screenshot, caused by the faulty Thunderbolt software 1.0 and 1.1 for Mac OS X 10.6.8

    OK, I have an update. I went to the Apple Store to test the CNN video playback on one of their 15" MacBook Pro models, just like mine, but with the Radeon 555 (mine has the 560). I saw the green screen issue on the video player screen as well. This leads me to believe the green issue is related to the video player, how it interacts with the video card or some combo. I have the peace of mind the problem isn't specific to my mine. Heres the screen grab from CNN player at Apple Store:
