    ninth, on this third unit it is not at all visible in every situation, already tried. However, only a different gray calibration persists with each step of brightness.

    Do you have DC dimming on?

    Try turning off Vibrant color effect pro in menu.

    2:02 - 2:04, for me the rocks are actually quite "visible" and has a lot of noise/artifacts (vertical lines) but they "arent supposed to be" as visible I think.
    Somehow the video is being boosted on the phone, turning the rocks visible but also showing a lot of artifacts instead.

    So for all of you who are seeing this black crush on the Costa Rica video (my OP8pro doesn't suffer from it), what are your settings regarding the following?
    - DC Dimming
    - Screen calibration settings
    - Refreshrate
    - Resolution
    - Vibrant color effect Pro on or off
    - Motion graphics smoothing on or off
    - Widevine certification L1 or L3 (check with DRM info app)

    mine were on dc dimming on, which does produce insane black crushes. like crazy. but it can be turned off ofc...then it's better at least.

    Everyone could try this video, ; be true to yourself.
    At maximum brightness , how "many of the blocks" do you see? (they are all not black).

    then at lowest brightness, in a dark room, how many do you see?
    and cycle through the brightness level.. you will see a lot of weirdness happening to the black levels.




    with DC dimming off, it's roughly visible to 14/15 to my eyes.
    with DC dimming ON, only to 45.

    To have the same results we need to know all your settings

    DC Dimming
    - Screen calibration settings
    - Refreshrate
    - Resolution
    - Vibrant color effect Pro on or off
    - Motion graphics smoothing on or off
    - Widevine certification L1 or L3 (check with DRM info app)

    If you share those, I'll test it

    Phone's back and overheating/batttery issues are gone, burn in remains.

    I switched off all icons again, just some remain which I can't switch off, anyone can tell me how I can switch them all off with rooting? I saw a way somewhere, but don't know anymore

    Try the video, try it yourself with whatever settings you want.. the key is discrepancy. Each panel will behave slightly differently.

    For me;

    120Hz, FHD.
    P3 calibration
    MEMC/Vibrat bla bla crap features OFF
    Widevine is unaffected on Youtube. But it is L1.

    Try DC Dimming OFF
    Then try DC DImming ON.

    without dc dimming and max brightness it's visible till 12 or 11 (in daylight/bright lighting conditions). in a darker environment i can see till 4

    So how does this works,with max brightness I need to see from what nr of square is visible to the eye!?.Cause with max brightness I can see the square from nr 6 and up,with DC dimming the same.

    are you in a darker environment? for me it's visible from 4 up in a darker environment. i think you should only see less bars with dc dimming on when the brightness is lower.

    yeah seems darker conditions then [e]1f44d[/e] then our phones are similar. and with darker i mean in comparison to the max displsy brightness (since it's made for outside Situations.

    I'm wondering the same. I'm doubting to return the device, what if I get a device that's worse.

    Well, yeah, with max brightness, you should be able to "see" more squares than with lowest brightness.
    Question is from where to where.
    And if it is same or worse with dc dimming.

    The idea is to see it, not squint as hell and try to discern something.
    You can try to go to a very dark room and take a photo of your oneplus with another camera if you have.


    Here are mine.
    The camera taking these photos ahve nightmode off , hdr off. and try to match exposure to what I see.
    But the camera will inevitably exaggerate the image.
    You can see at the lowest brightness, the greys change tint remarkably. This is not as visible to the eyes, they look grey with a tint instead.

    DC dimming off - Lowest brightness

    DC Dimming off - highest brightness

    DC Dimming ON - lowest brightness

    DC Dimming ON - highest brightness
    upload_2020-6-7_19-25-2.png


    At the highest brightness, both PWM or DC dimming are fine. So far so good.
    but at lower and lowest brightness, the grey scale completely changes. Greys are more blacks, and so on.



    FW: 10.5.9 , didnt really change anything in this regard.
