    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

    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.



    Aha now I understand what you're saying,so mine looks fine on highest brightness now that is darker outside and in my room, I can see from nr 5 ,lowest brightness from 7,but the colors remain fine,with dc dimming on the lowest I can see from 25-30, highest from 7,but it is know that activating that option is crushing the blacks.

    This is my third oneplus 8pro, throughout the ui the display remains uniform, except in the dialer with brightness towards 30%, it shows me the green subpixels

    Can any of you guys try a different display mode? srgb for example looks an awful lot better to me, in fact the display seems to display blackd properly on this mode? Gamma in the display tester app is also 2.2 always on this mode.

    Didn't improve in srgb. maybe even worse in terms of how each grey is displayed.

    Apple admits the blue screen error on the iPhone, will replace free for affected users. This shows the complexity of this issue, as it may be the combined effect of a batch of poor quality OLED screens.

    I myself decided not to buy the Oneplus, Samsung, Iphone now :D

    this is a software bug in the case of apple. this is not a new phone and it's caused by a software update. oneplus panels are just bad overall and not software

    Got a device produced in mid-May as my third device. Probably had even worse problems than the ones I got produced in April. Returned for the last time. I'm done with the 8 Pro and its low quality screen.

    I never tried DC dimming because I haven't needed it.

    In lit room with auto bright, visible to 14. I may be seeing something down to about 12, but I may be kidding myself.

    In lit room with max brightness, definitely 12.

    In dark room at about 20% brightness, 16.

    My display appears to be mostly crush free.

    Seems like due to fake pandemic OP decided to buy the cheapest 3rd grade displays from Samsung.
    I'm the VERY happy owner of OP7tPro (perfect phone, best I've had), but I can't really stand reading about all the problems with OP8Pro. It really looks bad at the moment for OP.
    If I was OP manager I would do everything to keep the customers happy even at the price of temporary loses/less income. Exchanging faulty phones will gain OP customers in the future, word of mouth is very powerful

    Try slowly raising the brightness on the screen in a dark room with that video and post the results. The boxes should evenly reveal themselves.

    I just tried. It is fairly smooth, no big jumps. If I get a chance to record it, I will, but it isn't a priority for me. I was giving my results as another data sample, not as a way to challenge anybody that is having problems.

    Hey guys, just out of curiosity i tried my Galaxy S10 and these are my results, i think green tint in low brightness is OLED´s inherent problem. Or maybe problem specific to Samsung panels?

    Well I think most Oled displays have this issue,and most of them are from Samsung,but till now nobody actually payed too much attention to it,cause these can be seen in low light,lately I saw even iphone 11 has a similar issue ,most people who get these phones won't look for things like this,I mean the average user.

    If you don't have it doesn't mean this issue doesn't exist,you just got lucky. And for cheaper models I'm not sure samsung is using their own displays,they also have a contract with a Chinese display company,they actually want to use Chinese displays in their next galaxy series.

    Yeah i think you are right. I never noticed this, until i tested the 5% gray picture, after i read about OP8 Pro issues.
