Content with white text on a black background highlights the issue the most.

To add further to my previous post. I have since compared my 10.5” IPP with my 5th gen 12.9” in a dark room whilst using Anki in night mode, and the mini LED just blows it away, blooming or not. I’m going to keep this bad boy.
Ah yes I see it now. I can actually understand why some people can be frustrated with this. I always read on my iPad before turning in for the night and it’s clearly visible in dark mode.

Just for curiosity, has someone done a tear-down to determine the no of mini-LEDs across the X and Y axis? Be interesting to know how many square pixels are affected by an individual mini-LED

I just bought my iPad today and the blooming is easily noticeable, particularly, but not exclusively, in high screen brightness/low ambient light conditions. To test whether a specific app was more to blame, I took a screen shot of a particularly bad example (Anki in night mode - white text on a black background), opened the screen shot in the Photos app and also opened it in Procreate for comparison; the blooming was just as bad in each of the three apps displaying the same content, unfortunately.

Personally, I am disappointed, but I’m prepared to give it a bit more time to see if I become inured to it.
What you’re referring to isn’t likely the problematic blooming. The problematic blooming is caused by the physical LED’s being larger than the pixels that contain the content you’re displaying. As this is a physical effect of the interaction between the panel and the backing LED’s, it’s not something you can take a screen shot of. (This is why you see examples where folks are taking pictures of their screens). Because of how your eyes work, the brighter the screen, the less likely it is that you’ll see this effect (it’s like trying to see faint stars in the sky during a full moon).

What you’re experiencing is the normal optical glow your eyes perceive when looking at any bright object with a black background around it (again, like trying to see faint stars on a moonlit night). If you have an iPhone, turn it to maximum brightness, then restart it, you’ll see the same happen around the Apple logo on that perfectly black background, too. When you consider that the iPad’s screen is capable of getting even BRIGHTER than the OLED screen on the iPhone, then the effect will appear more pronounced.

The reason they used screenshots was to compare the same source image across different apps to test whether different apps may show more or less blooming than others.

Yes, and the “blooming” as they described it looks “just as bad” in all of them. That combined with “high screen brightness/low ambient light conditions” is indicative of just plain glowing. It’s not likely that anyone’s eyes would be able to see the problematic blooming at high screen brightness levels as the delta between off pixels and on but black pixels wouldn’t be able to be seen.

Coolguy has already addressed the first point.

With regards to the second point: No, I disproved your hypothesis by completely covering the white text and I can still just as easily perceive the surrounding bloom and the very obvious uneven lighting of what should otherwise be a uniformly black background. It’s bloom, not my eyes.

I bought the new 2021 iPad Pro thinking the screen would be way better than the 2018 model I‘ve had. But it‘s the opposite.

The blooming is horrible, especially at night when watching a movie. Even when the UI elements are hidden you can notice the horrible blooming on top and bottom and it seems over the footage itself which eliminates any perfect blacks that the new mini-LED screen was supposed to accomplish. Therefore I see no real difference in screen quality but actually worse because of this distracting blooming effect.

Really disappointing. Did Apple test these screens before putting out in the wild? How can they claim the screen is better and release this?

And can it somehow be fixed with a software update? Probably not I assume.

Fully agree

According to this review from Dave2d which is a very reputable reviewer:

The new MacBook Pro does not suffer of blooming like the M1 12.9 Ipad does.

Even though according to Gizmodo the MacBook Pro 14” has fewer Mini-LEDs than the IPAD ( 10,000 On the Ipad vs 8,040 on the Macbook Pro)


I am just pissed off that Apple launch the MINI LED screen for the IPAD in such a beta state.

It has always been like this with Apple, I'm sure the next iPad Pro won't have these problems anymore because of [insert artificial reason].

I still love it, but I would of course prefer the backlight algorithm of the new MBP if it's true what Dave says.

I was afraid this was going to be the case. Oh well, we’ll have to put up with it until the next iPad Pro is released. I would love to see the new laptop in the dark though.

You think it’s the algorithm and not better screen architecture?

Oh, no, I don't know anything of course. :) It's also possible that it's currently technically impossible because they can't control smaller zones with the available hardware.

Well if the MacBooks prove to have little to no blooming then we can scratch the technically impossible off the list. :)

yeah, but it can be caused by the hardware used in the iPad. That wouldn't be fixable. I hope I'm wrong though, of course

So, there are folks here that would say the iPad Pro does not suffer of blooming. When you consider that the standalone monitor has been reported by some to have blooming, it’s hard to believe that anything in more constrained and fewer light zones wouldn’t. I have no doubt that there will be pictures showing the horrible blooming of these :)

If you can see the blooming on the iPad, you’d see them on these laptops and very likely, the Apple monitor.

Well, there it is. Pretty much the same as I see on my 12.9". At least the iPads aren't bum panels.

I still say it's their dimming algorithm, there shouldn't be such an obvious timing difference, it isn't present on Samsung's Neo QLEDs. I also think they're trying to avoid black crush where crush would probably be preferable in video/media consumption.

Could be algorithm. 2,500 zones should produce a smaller bloom than we are seeing IMO.

Interesting, iPad and MacBook look pretty similar to me. The XDR display though, lol, is there a similar thread to this one here? You can clearly see that Apple improves the tech fast.

I've had the 2021 12.9" iPad Pro for three days now. The screen is gorgeous! Last night, I was watching an episode of "The Morning Show" in bed with the lights out. At the end, the screen faded to black -- true black, rather than the dark gray I'd been used to with my 2017 standard iPad. Then the white Apple TV+ logo and menu came up, and the blooming was clearly visible. While it was annoying, I figure the amount of pure-white-against-pure-black-background content I'll be watching in a totally darkened room will be minimal. White text with mixed graphical content on a black background didn't cause noticeable blooming for me. While I of course would prefer no blooming whatsoever, everything else about the screen is beautiful, and everything else about the iPad is amazing, so I'm not even considering returning it.

that's what I don't get about the 12.9". Sure, it has some blooming, that's the tech right now for you, but damn is this screen better than anything else otherwise. I can't understand how anyone would want to return to the grey-ish blacks and in comparison almost non existing HDR punch just because it shows some blooming somethings
