    @Mindtaker - if does not jump between black to very light gray in one step then it is good.
    This is actually the problem: jumping from one very dark shade to a totally bright grey... and on some levels of brightness we get a brown/red box between them. it is horror... :(

    On Lumia 950 the box no 3 is brown/red and it is the most different. It has nothing to do with a grey gradient transition. Therefor I think it is the principal generator of the unpleasant effect in the dark scenes movies/frames.

    My question now is if the error 31 regarding the display driver exists or not on other devices with wm 10?

    Apparently the XL also has that error but the display works ok...

    Mmmm interesting, if I move the green/purple slider in color profile on the 950 all the way towards green or red, the color of the box n4 f*cks up and gets weird but if you calibrate it gets perfectly grey.

    The same thing does nothing on the XL, in fact I can't fix the green tint on greys...

    If it is also confirmed for other devices then the calibration problem it might drop at the firmware level for l950. I was hoping that redstone might include a fix for this issue...

    Can you provide a screenshot of the combination that provided a very good grey? I only get either green or purple or very bright gray on that 4 box

    Yes, 0-3 are black.

    Well to a good screen yes, 0-3 are seen as black, although in reality only 0 is pute black. The eye simply cannot see a difference. I mean on any other display I cannot see the number within (all numbers are pure black) the first 6 cells.

    Do you have problems with videos on the 735? You shouldn't have....

    Can't check for me in this moment, my friend says he doesn't note anything.

    Same issue on Icon, N8 and C7.

    With this settings the block 3 is not any more red/brown but the jump of the gradient from block no 4 is still too evident.

    Maybe the stain thing is made on purpose to save battery.

    LOL... that would beat Jobs's "you're holding it wrong" excuse :))))))

    now seriously, the 950 has a screen calibration problem. The XL so far doesn't, meaning at least videos look as it should.
    I want the same XL screen rendering on my regular 950. Nothing more, nothing less.

    After the Redstone first build and the next firmware update, if this problem is still there, it goes back to service and I will not get it unless it has the screen fixed (replaced screen/phone). If that doesn't work, then money back and XL then. One way or the other...

    It appears that the display driver cannot be loaded.
    I've entered into Device Manager on PC with the 950 on developer mode (Device Portal) and we have a "Microsoft Basic Display Driver" with "ProblemCode : 31" - I.e.: windows cannot load the driver.

    Attachment 122208

    This might be a cause for our problem with the screen....
    Basic Driver? This is your answer for all the issues and low graphic performance. There should be a decent driver for the GPU, not a generic one. Why there is none? I do not know...

    Yes, it can be the problem. The thing is, the XL has the same problem, but that one behaves good.
    Now maybe XL's panel is better calibrated from factory and doesn't need further calibration in drivers... I really do not know....
    And looks like nobody from MSFT gives a s***t...

    2 Microsoft employees comment on reddit when new build is released. We can try...

    https://www.reddit.com/user/jenmsft is one.

    you really expect them to admit that the drivers are generic?

    I've tried twice allready on Twitter with Gabe Aul and Daniel Rubino (not MS employee but editor in chief here) and they both simply ignore my questions. Either MS knows and is trying to fix it without noise or they do not care.
    I also sent emails with this to like 7-8 big online sites in this area (GsmArena, PhoneArena, Windows Central, WinBeta, WMPoweruser, All About Windows Phones, The Verge, Engadget, Poketnow). Only GsmArena wrote a blog post about this, the rest just ignored....

    But it is not a long shot contacting those floks on Reddit too. Hope never dies :)

    Yes, 0-3 are black.

    I saw you escalated this on Reddit with Jen (MS employee). Upvoted and escalated too, with a link to this thread. Let's see what is happening...

    Also, when watching DareDevil on Netflix, there are a lot of completely black section, where they should obviously be grey. That drove me nuts.

    Amir, do you have a special color profile (other than standard) or manual modifications?

    Hello,
    the latest Windows 10 Mobile build 14267 (insider fast ring Lumia 950) seems to have solved a big part of the problem on my phone.
    Your video (Superman vs Batman) was unwatchable for me too but now it's good (not really good, but much better) .
    I have no pixelation in dark scenes even though the black gradations are not faithful to me.
    I tested all my other videos and compared with my other phones (Nexus 6 and Note 3) and have almost the same thing.
    sorry for not doing tested as requested but I 'm lazy and it seems to me so obvious as problem...
    Anyway now I really think they know the problem and they are working on it (probably thanks (?) to people like you, so you have all my respect).
    That was just to make a comeback after the change I 've seen .
    Peace from France

    For me look like it is the same, at least in the same videos. Nothing changed.
    Does someone else updated to the new Insider Build and had better calibration?

    Thanks
