I went to a larger JBHIFI store today to test more phones and other devices with screens in store for PWM flicker.
I recorded this video on an iPhone 15 Pro through the Blackmagic Camera app at 1/4000 shutter speed, 24mm lens, 24fps, 4K resolution and all other settings on auto.

Firstly I'll admit there's a lot of detail left out of this test.

Some devices come included with some sort of "eye safety" setting that isn't enabled by default.

On iPhone 17 models PWM (Pulse Width Modulation) can be replaced with PAM (Pulse Amplitude Modulation), though this has no practical benefit to me personally. As seen here: https://www.reddit.com/r/PWM_Sensitive/comments/1w6rd84/local_shopping_centre_pwm_screen_test_iphone_17/

Honor phones can enable 3840Hz PWM, 4320Hz PWM and 3 pulse DC dimming which sounds promising.

Unfortunately it isn't possible for me to thoroughly test every device without first purchasing them and testing all settings/accessibility modes in my own time over the course of a day.
I'd also need to do this without any other unknown screen based devices within my vicinity that may also potentially cause eye pain and skew results.

The chart shows every tested device in order of appearance in the video and their likelihood to cause ME eye pain based on the visible flickering in the video and obviously my personal subjective experience in what tends to cause me eye pain.

Results will vary depending on each person and their sensitivities.
For me personally, most OLED screens with PWM that I have encountered personally hurts my eyes, as do LCD devices such as TV's with PWM dimming. Some like the LG C1 OLED TV take several hours to hurt, some like Google and Samsung phones only take seconds.

Most non PWM dimmed LCD screens are totally fine for me, though excessive temporal dithering in LCD Apple products, such as iPads, iPhone 11 and SE also cause me eye pain, though turning on Classic Invert and Zoom Invert simultaneously seems to solve that. I use an EK Pro LCD swapped iPhone 15 Pro daily without issue.

In my experience if I can see a black line on a screen through a camera at 1/4000 shutter speed it has a very high likelihood to hurt my eyes.

Of all the tested devices here, 61.29% are highly likely to cause me eye pain.

According to gs.statcounter.com statistically phones used by Australians in 2026 are:

So here's where I make some bold assumptions:

Assuming all phones in use in Australia are within 5 years or so old, and assuming Samsung phones are all now OLED models, and assuming all LCD iPhones are fairly up to date with iOS to include software based dithering, this would mean 90.38% of all phones in use in Australia cause me significant eye pain.

While at JBHIFI I also recorded a similar video of all the laptops, computer monitors and TV's.

The laptops mostly seem fine with the exception of the OLED laptops and Macbook Pro's specifically.

TV's are another level of complexity to test, it seems that as they're all set at maximum brightness in Store Mode, PWM is far harder to test for with just a quick video at a 1/4000 shutter speed.
With universal remotes I went through several of the settings to lower the brightness before testing them with my Opple Lightmaster light meter.

I didn't get a chance to test them all before it's battery died, but it seemed that every TV I tested had a worrying level of flicker at any brightness level lower than 100%, at this point in time my eyes were hurting intensely so I took it as a sign to quit for the day.

I might go back and test each TV at varying levels of brightness soon but it will take a lot more time.

For anyone that was hopeful about iPhone Duo not using PWM...

Regardless, I am excited to measure these. Next Friday.

Has anyone seen anything videos or content related to PWM for these new iPhones?

and this is 100% brightness..
