Nightmare…so sorry to hear that.
If it’s any consolation, there was an active contributor on this thread a long while back who experienced the same physical trauma (seizure) using a new iPhone 15 PM while typing an email.
Clearly- for some people, Apple displays have become exceedingly toxic.
(and they didn’t used to be)
Thanks, it was a shock. I’ve used Apple devices and computers since the iPhone 3GS and never experienced anything like that. I had tested a 13” MacBook Air M4 and while that was really difficult to use, I was able to test it for a few days. I exchanged it for the 15” version thinking it was the panel and boom…
Interesting about the iPhone 15 PM. I first realized I had a problem with their screens when I tried upgrading from my iPhone 13 to the iPhone 15 Pro and couldn’t focus on the screen at all - it felt like trying to read something behind a waterfall. I had used the iPhone X, iPhone 11 Pro, and iPhone 13 Pro prior to this with no issues. I learned about PWM and dithering after that.
I’ve been on my iPhone 13 on iOS 15 ever since with zero problems. My mom has an iPhone 13 she purchased at the same time from T-Mobile (fall 2022) and while iOS 18 isn’t as comfortable as iOS 15, I don’t have any severe symptoms using it. iOS 16 and 17 were bad on her phone, though.
What’s very curious to me is after returning the iPhone 15 Pro in May 2023, I went to several stores: the Apple Store, Best Buy, Verizon, and T-Mobile. I took my iPhone 13 manufactured in 2021 and held it side by side the iPhone 13’s Apple has starting selling as the “budget” model for the iPhone 15 cycle. All of the new ones were unusable side by side. So something changed on the hardware level after 2022, too, in addition to software. I used to be able to use my 12.9” iPad Pro M2 until I updated it to iPadOS 17.
My guess is that it’s a combination of really high modulation PWM with a low base frequency and dithering/FRC. I don’t have another explanation for what’s going on…those are the only things that changed. I can tolerate certain LED lighting, too, so long as it’s a low modulation and fairly high frequency. Apple is just using too much low frequency PWM and dithering and there doesn’t seem to be a way to mitigate it without using external displays or older devices on an older OS. I only care about professional work so I’d happily use anything if my software, Avid Pro Tools, would work.
