I dont know what to do anymore. Most phones dont work for me. I need a Ipad for school and it doesnt work for me either. I am so tired. Tf should i do? Does anyone knows eye friendly ipads that are good? The s8 ultra worked for me but its not an ipad.
TM-39-25 is a document from the Illuminating Engineering Society that puts forth a classification system that seeks to reduce human responses to flicker. I often call the classification system itself "TM-39-25".
The system utilizes three different flicker effect visibility metrics, Mp, SVM, and PAVM. These metrics are scores computed from the flicker waveform that seek to predict the likelihood of a "temporal light artifact". I go over each metric in detail in the video, but here's a summary table:
Simply put, a temporal light artifact is a visual disturbance of some kind due to flicker. TM-39-25 classifies light sources based on all three metrics simultaneously. I see this classification system as a vastly improved (but not perfect) replacement for IEEE-1789 classification, which are the frequently posted here as part of the results the Opple Light Master produces. Here's how the metrics scores map to the classifications:
I think this standard can be used as a replacement for the IEEE-1789 classification. The three metrics or "scores" it uses provide much more useful information and were created based on the results of experimental studies.
I have built this system into the flicker meter I'm working on (TLM-110), and used it to measure a variety of bulbs:
You can see there's a wide range of classifications in the bulbs I tested, as well as a large spread in the scores. The bulbs that are "Not Recommended" are unbearable to me, while the bulbs that are "Better" are much more tolerable.
I think this system has the ability to be broadly useful, especially for non-experts. However it isn't perfect. Firstly, while it technically applies to all light sources (displays included), it is most relevant to lighting such as bulbs and lamps. There are likely screen-specific flicker effects that haven't been described yet. Also, it mainly predicts the visibility of flicker artifacts, which are visual disturbances, not health effects. I think flicker artifacts and visual disturbances may be correlated, but there is not a one-to-on relationship.
Thanks to u/Rx7Jordan for making me aware of this standard.
So i had a S8 Ultra 2 years earlier that worked good. Now ive wanted to try the 2021 Ipad Pro 12,9 because it has no OLED and i wanted to use GoodNotes. But i get dizzy by looking at it. Its very strange? Do you have an idea?
This screen is confirmed pwm free, however the "68B colors" is kinda scary, I can imagine the headaches without getting the tablet. But if it is a native 10 bit, the flicker would be easier than a straight 8 to 12bit or a 6 to 12bit.
I mean yes the MacBook Pro display flickers, but at a whopping at 15 Khz. But those cheap LED lights that are literally everywhere I feel they should be much worse than every screen that is out there
I've had my Pixel 10 Pro for a year and I'm really struggling with it. Before buying it, I had no idea PWM sensitivity was even a thing — but looking into it now, I'm fairly convinced that's my issue, since I don't get this problem with any other screen I use.
I'm looking for a replacement that still feels like a proper flagship, especially camera-wise. I liked the look of the Vivo X200 Pro/X300 Pro, but getting a genuine global version in the UK is difficult and expensive. The Honor Magic 8 Pro seems like the "safe" choice for PWM, but I'm not keen on its image processing.
The Oppo Find X9 Pro looks close to perfect for me, and its PWM spec looked great on paper — until I read that independently measured, real-world PWM comes in well below the advertised figure. That sent me down a rabbit hole of PWM vs. DC dimming vs. dithering, and honestly I'm now a bit lost on how it all actually comes together in terms of real-world comfort.
So my question for people who understand this better than I do: the measured Find X9 Pro figure I found puts it roughly in line with what the Pixel 10 Pro is advertised at (not even independently tested — I can't find anyone who's actually measured the Pixel 10 Pro's real-world PWM). Given PWM frequency isn't the only factor at play, would the Find X9 Pro likely still feel noticeably better than my Pixel 10 Pro in practice? Or am I likely to be disappointed and end up in the same boat?
I tested/recorded it with samsung pro video with shutter speed of 1/12000, i am seeing black bands, with both the anti flicker option ON and OFF and brightness was also maximized via the dropdown brightness slider.
I increased and decreased the brightness but the black bands were present continuously.
As the title says. The 55C8L is competitively priced here in Europe and it looks like everything I want from a modern TV (high-frequency PWM, Min-LED, Android TV, good quality and good reviews overall).
Has anyone here tried any TCL TVs of the SQD variety? Still worried about the fact that it's PWM.
I visited a local electronics store in Slovakia and checked the Pixel 11 Pro. In Accessibility Settings I enabled a setting for sensitive eyes (480hz) and shot with a 1/6400 shutter speed the screen of the Pixel 11 Pro with 100% brightness, 75% and 25% and 0%..
As you can see lines are deep dark black so PWM modulation will be around 99% and this will be terrible for the eyes. In the coming days I am 100% sure that Nick will confirm the same. I also tested the vanilla Pixel 11 it's the same in terms of modulation... don't kill me for my basic explanation:)
I'm very sensitive to PWM, with headaches minutes after using smartphones with it. So here is a list of smartphones which I'm interested in buying, and I want to know from you guys, which ones are safe. Thanks!
- Moto Edge 50 Neo - LTPO pOLED
- Moto Edge 70 - Extreme AMOLED - pOLED or AMOLED?
- Moto G67 - Extreme AMOLED - pOLED or AMOLED?
- Moto G54 / Moto G56 / Moto G57 [IPS]
I know every phone is going to affect each person differently, but after struggling for over a year trying to find a phone, I needed to share that the Motorola Edge 2026 gives me zero symptoms.
Due to eye strain and headaches, I've tried and returned:
I initially thought I had to steer clear of OLED, but even modern IPS-display phones cause me headaches or eye strain gradually. I don't really know what is different in the Moto Edge 2026, but it is working very well for me for three weeks now.
The main downside of this phone is it only has 128 GB storage, but it's 100% worth not having a constant headache for the next four years that I use this phone.
Good luck!
i'm buying a tv. i'm thinking of buying one of the oled tvs that claim to have 0 pwm but 60hz flicker rate.
as you can see, the luminosity dips about 20% every 1/60 second. would this cause eye strain?
So this is how it looks like
I bought a g57 power, because it has lcd display but the strange thing is it don't work for me. I feel the same as the oled display. Before i had an iPhone 11 and didn't have any problems which is strange. Now i am planning to try Honor 600. Somebody to have the same as me?
Now here is some discussion.
It seems that both the Pixel Pro 11 and the Iphone 18 Pro will use the M16 Oled Panel from Samsung. So far, the OLED itself seems very good. No visual artifacts, and no greenish teint like on the 17 Iphone generation.
The interesting part comes now:
The M16 OLED Panel only means the actual display panel and not the "Backplane". In the Iphone 18 Pro the BackPlane will be made "PLUS" which will rely on an altered mechanism for the electrical signals. Mainly using OXIDE instead of SILICONE in the transistors, which makes the whole electrical current way easier to control with less leakage and better stability. And thus probably less necessary PWM because color accuracy will be way better to control. That could also be why the PIXEL was released earlier, because of after the rival , the PIXEL will have no market anymore to be sold on.
So for me, I am hoping for the Iphone 18 to be at least a little better than the current OLED PWM phones.
I have been waiting for the release of Pixel 11 pro XL. Currently using Oppo find X8 for the fantastic pwm frequency but really missing my older devices like Samsung ultra,Pixel,Iphones .
Please help about the PWM frequency of Pixel 11 pro XL. Anybody has any update on this? Also help me decide if it is 240hz on pixel then how about Iphone 17 pro max. Really need the help on this topic.

Many of you have noticed that r/PWM_Sensitive has gone through some growing pains when it comes to how posts and comments are moderated. While the subreddit was never unmoderated, it became clear that some additional help was needed due to personal circumstances, and that a fresh approach to moderation would benefit the community.
We are happy to share that u/the_top_g, the creator of r/PWM_Sensitive, has graciously stepped aside to welcome in three enthusiast community contributors to help with moderation and the future direction of the subreddit. We sincerely appreciate the trust he has placed in us and, most importantly, his work in creating this community in the first place.
The interim moderation team is currently discussing ways to improve the subreddit while preserving what has made it such a useful resource for people who are sensitive to PWM, display flicker, and related technologies. Our goal is to keep this an open, welcoming, and informative community where people can share their experiences, testing, research, questions, and device recommendations without unnecessary barriers.
Perhaps the most noticeable (and controversial) issue has already been addressed: the previous AutoModerator configuration is gone.
This means comments should no longer be automatically removed simply for using common words or phrases that naturally come up when discussing PWM and related topics. This includes “temporal dithering.” Members banned over this issue are also being reinstated.
That said, we ask everyone to continue keeping discussions primarily focused on PWM sensitivity, display technology, eye comfort, device experiences, testing, and closely related subjects. Normal subreddit rules and Reddit-wide policies will, of course, continue to apply.
This is only the beginning. We're reviewing the subreddit's rules, moderation practices, organization, place within the wider community, and other areas where we believe improvements can be made. As those changes are decided upon, we'll communicate them with the community.
We also want r/PWM_Sensitive to be shaped by the people who actually use it. Constructive feedback and suggestions are welcome. If there are things you think could make the subreddit more useful, organized, or welcoming, please let us know.
Finally, thank you again to u/the_top_g for creating r/PWM_Sensitive and building the foundation for this community. And thank you to everyone who has contributed over the years -- whether by sharing measurements and research, documenting your experiences with different devices, answering questions, or simply participating in the discussion.
We're looking forward to the next chapter of r/PWM_Sensitive and making this community an even better resource for everyone.
p.s. Check out the new (temporary) subreddit logo! 😁
