The current iPad Pro 11 2020 is trying to strengthen its position as a laptop replacement with touchpad support and an even faster performance. Additionally, the cameras have been improved and the display now supports 120 Hz. In this review, we will take a closer look at Apple's exclusive workhorse.

seriously.. for a content-consumption device, reading, watching movies, casual email etc.. how can they have gone back to using PWM in this generation?

Worst update,  how can you say this is what an update should look like
Who uses camera?
Minor Cpu update
Just 128Gb storage

This isn't by far an upgrade. Lack of UWB and not even a new generation of SoC makes this version a side step not forward. 2018 iPad users can safely wait for next version which should be a real upgrade.

"now"? iPad Pro has 120 Hz display since 2017...

I'm blown away about this. We've had Asus, BenQ, and Dell monitors advertising flicker free for years. Not only will we be viewing this a LOT, but it's quite pricey in the higher storage tiers with LTE.

I'm holding out hope for the 12.9", but maybe this'll work to our advantage if that's got PWM flickering as well. I'd be waiting for the falls rumored mini LED and hopefully we'll get an A14X as well. My only concern's that mini LED uses dimming zones AFAIK and that might mean PWM.

Are you out of your mind, the PWM frequency is 1.3MHz, that's 1.3 million times per second, it's a higher frequency than AM radio. I'll give you all my possessions if you can actually see something blinking at 1.3MHz

this has been rehashed a million times across the web... it's not that you can SEE the flickering (no one can), it's that it produces an effect of eyestrain over the longer term. people feel this (including myself); it made me choose the iPhone 11 over the 11 Pro simply because i hated the PWM on the Pro.

in 2020, no devices should be doing this shady cheap dimming crap at the expense of users' eyesight, health and comfort. i'd take reduced battery life any day for clean clear light.

It could be 1300 and I still wouldn't go near it. I'm not God. I don't know what my eyes can actually perceive and translate into an adverse affect to eye heath. Some of us still use incandescents for this same reason! :D

I know of no other place to determine PWM as well as here. So that's why I'm posting and hoping word gets out more and more about the problems this tech can cause.

I'd rather have a flicker free 12.9" A12Z powered iPad Pro with NO PWM than a hypothetical...

14" A14X powered iPad Pro using pulse width modulated backlighting for the Micro LED with proper dimming zones that supports both HDR10 and Dolby Vision.

It could have the same camera module from the upcoming 12 Pro, 8 GB of RAM, 2 USB-C's, a headphone jack, water resistance, and come with a free Lifeproof case. It still wouldn't matter.

It's that important. Flicker free is that important. My eyes are that important.

To add to that, I'm not even sure that we actually are looking at PWM, the scope trace next to the frequency measurement just displays a noisy signal.
If anyone from notebookcheck actually reads through these comments, it would be great to get a video of the PWM in action like they did for the recent Macbook Air 2020 review, because there, what they call PWM isn't actual pulse width modulation, it's just a boost circuit with no output capacitor which oscillates slightly between the charge and discharge phase of its cycle, so the output wave will oscillate between say 10 and 12 volts, with the very telling exponential rising and falling edges.
This is completely different from PWM that oscillates at a low frequency between say 12 and 0 volts.

You sound a LOT more knowledgeable about this than I know I am, so thanks!!

I know the review of a Sony TV states there IS flicker, but it's not PWM. Said TV does NOT bother me. Maybe this might be similar to what you're trying to explain?

Anyway, I appreciate your comment and hopefully we will see some BIG buttons for FORUM @ the tops of these web pages as well as some moderation from the testers here @ NC.

Worst case scenario, I'd have to try both sizes out, return both, and wait... :p

...yada...yada...AWESOME iPad review.

Help us Redaktion, you're one of many new hopes‽‽‽

"this is what an update should look like"

??
I think you guys hit the new low.
wha't's so special about this generation's update?
2020 is basically the same 2018 ipad pro in disguise.  the only substantial upgrade is AR camera which is not yet utilized by mass.

>The rigidity of the tablet is okay
Okay? I literally saw a guy rip it apart with his bare hands, it's most certainly not okay. 5.9mm is pointlessly thin, 2mm thicker and 200g more could make it far sturdier and with a larger battery, likely better thermals too though I don't know if Apple's tablets still need that.
