Blooming/Elevated Black Levels on new 16" MacBook Pro.

WilliamG said:
Here's a screenshot from the end credits of Blade Runner 2049. This in motion is terrible, but notice too how the backlight is not off for the surrounding area, so there's elevated blacks in dark scenes. Also, even ABOVE the black bars the screen is showing elevated blacks.

I presume you are streaming this? And if so, over what platform?

I have the 14" MBP and just watched the end credits of Blade Runner 2049 streamed from Movies Anywhere in Safari and I do not see anything close to what your video and picture are showing. I do not see any blooming around the names in the text crawl and my black levels look consistent (and dark) around the entire screen. My brightness is set to maximum and I am in a dark (but not pitch black) room.

Fired up Foundation on AppleTV+ and I do see a bit of bloom around the Apple logo and especially around the "+" when it goes to maximum and there is a very faint (but noticeable) bloom around the "Previously" text at the start of the recap. Once the show is running, black levels are excellent and not seeing any blooming on the white text in the opening credits against the dark areas.

View attachment 1880250Took a pic with my phone.. super exaggerated. In real life It’s not even noticeable in a dim room and at normal viewing distance. Looking up close (6 inches away) you can see a bit of blooming but it doesn’t bother me in any way.

Agree, all the exaggerated photos captured on camera, it isn’t that obvious to the naked eye.
 
I just watched ending credits from The Morning Show and I don't get ANY blooming on my 14". Even with brightness to the max.

I have this running from my Plex server from the UHD original. Either in the Plex app or in Safari, - same issue.

recording video with what? whers your video recorded with a professional video recorder plz...not with a smartphone that is irrelevant

Ok. You’re right. My iPhone 13 Pro that I manually adjusted exposure for to represent what I actually see…is irrelevant.

Now, if you actually looked at the video, I included the MacBook keys in there so you could see it wasn’t overexposed. The PICTURE I overexposed on purpose to illustrate how the miniLED backlighting is not shutting off in dark areas.

of course in real life isnt that bad...but still , dim room with 1000nits....i mean forget about the display, you should care more about your eyes

Compression is also a factor. A background in a video might look like it is supposed to be black but if is not true black and has subtle compression artefacts creating color values then the display won’t interpret it as true black. Such compression and chromatic aberration usually happen along the edges of bright areas and objects in images.

Absolutely. Except on my OLED LG CX this is pure black. And this phenomenon is visible on any movie, including in the black bars (e.g. 2:35.1 movies). That’s simply not right. It’s like the display isn’t fully shutting off the LEDs when it should be.

didnt known the keys are on display keyboard....to record a light from a display(1000nits) is different from the light from behind physical keys...

Well the good thing is that mini led behavior is software programmable so if they want they can reduce blooming with updates, but don’t expect some kind of perfection on a laptop display. It’s amazing as it is.

once...the LG has OLED...and twice i bet that LG is not producing 1000nits....so in not apple for apple
Find and record for us an OLED with 1000nits

exactly, until micro-LED there is no perfect display tech until now....you cant have them all...i mean Apple could go with mini-led with just 500nits and this blooming effect at max brightness would have been a lot better
This is not healthy, nobody should watch in a dark/dim light condition to a display that is over 500nits

You’re missing the point. It doesn’t matter how many nits. The black surrounding area on that screenshot should be pure black on miniLED.

can you record a video with a prof camera watching a movie at half of your display brightness? Please, thank you
If that is still an issue, then you should return your machine
 
An they come again with overexposed pictures.
I see nothing on my Ipad Pro in daily use.

Even our human eyes are not perfect. Our vision also adds blooming effects around bright objects on dark areas. Just go outside and look at a street lamp at 2AM in the morning :)

Even worse when we are drinking alcohol or some other intoxicant.
