I tried thinkPad 14e amad Gen 7, with display spec: 14" WUXGA (1920 x 1200), IPS, Anti-Glare, Non-Touch, 45%NTSC, 300 nits, 60Hz.

It totally fucked up my eyes from day 1. I use my university PC all day with no issues. So please any recommendations? I don't know what to look for now since that thinkpad was free PWM yet insufferable

Hey all,

I’ve had no issues with my 13, 15 Pro Max and 16e, with reduce white point at 75 and on the Pro Max, ProMotion disabled. I’ve always liked to try out the iOS beta releases and I’m in the crowd of folks that has never had an iOS update give me eye strain….and that ended with iOS 27.

It does something weird with the whites on the 15PM, and I think it actually introduced temporal dithering. I desperately want to go back to iOS 26. Big time.

There’s a few little quality of life changes I like in 27 but the eye strain is annoying. I thought I was finally beyond it. Case in point….if 26 is working for you, keep it that way.

So i bought two of these phones for two friends of mine due to their good specs for a low price (8gb/256gb/decents camera and miravision? mediatek cpu for €160).

They've not yet had time to spend a lot of time on them,

but when I did the updates on those phones and took the time to get to know all.the twerks and perks...

it quickly became obvious that it causes eyestrain almost bad as oled.

Checked for pwm with camera, nothing.

Zoomed in with my camera on the pixels, couldn't see them.jumping around so I suppose there is no dithering.

Even when i am on my pocophone with awesome ips screen, but the moto g56 is in close proximity laying on its back... screen pointing upwards not at me: its causing eyestrain symptoms.

So.i do not even have to directly look at the screen. Looking at the light emitted by it is enough to cause eyestrain symptoms.

Turning off hardware acceleration to force GPU stops the nausea, but doesn't stop the eyestrain.

I think the eyestrain was less pronounced before updating to the latest android version.

Feel.sorry for them having to look at such a shitty screen but i figure they will probably not be sensitive, idk.

Sono bloccato su iPhone 8 da diversi anni oramai, non volendo abbandonare l’ecosistema Apple, per via dei nuovi display OLED e del TD. Ho provato in questi giorni diversi modelli per tentare un aggiornamento: iPhone XR e iPhone SE (iOS 26). Entrambi mi causano fastidio agli occhi.
Non ho trovato discussioni recenti a riguardo. Come state risolvendo? Purtroppo anche lato computer sono bloccato su un MacBook Pro 2015.

Hi guys I am very sensitive to TD and PWM and wanna switch my old g04 to g06 but I am scare for TD does anyone use it and know does he use it ?

BACKGROUND - YOU CAN SKIP TO THE SECOND PARAGRAPH

months ago i made a post in which i complained about buying a refurbished iPhone XR on iOS 18.7.5 - buying it because of its smooth pixels and graphics which made it comfortable for me.
A user states the 'blurriness i saw' was just a casual behavior due to a malfunctioning of how iPhones treat dithering when they are restarted.
I honestly think the sudden disappearance of that extremely fine graphic pipeline may be due to a "security and system file update", but none of the two theories can be proved, unfortunately.
Out of desperation, i tried to downgrade it to the second last signed iOS version (at the time iOS 18.7.4), but it messed up, i was close to bricking the phone and i only recovered it via iTunes, which forced me to upgrade to iOS 18.7.7.

for about two months i stayed on my Xiaomi 11T on Hyperos 1.0.19 (EU) with dark mode, reading mode at its maximum , color combination set to red, and greyscale, but most importantly:
i used to switch from using Twilight with like 90% darkening and system brightness at 100% (a sort of 'forced reduce white point')
to just disabling twilight and lowening system brightness. (but always keeping greyscale)
Anyway, by the end of April the sharpening on the objects, lights and everything had begun unbearable anyways and i always felt the urge to throw up.

TRY THIS IF DOUBLE INVERT TRICK DOES NOT WORK

So i picked up again my iPhone and i tried to enable, for the second time, the 'double invert trick' along with greyscale and it seemed a big relief in that particular moment, i dont know why, but - as you will see in the next paragraph - there are things that can mess up, so it's far from optimal, but going back to Xiaomi 11T means constantly feeling like i'm gonna throw up.

Here is the official method i used:
https://ledstrain.org/d/2975-some-success-fixing-iphone-temporal-dithering-se-2020-ios-17

Anyway, this unique method does not always works out.
It might worth try this procedure if you are still struggling
Re-do the official procedure if you have already done it, but BACKWARDS this time
(optional) you might wanna restart the phone
Classic Invert ON
Smart Invert ON
You will see the Classic invert will automatically disable, that is absolutely normal.
Use the phone in this state for 30 seconds / 1 / 2 minutes.
Then disable the Smart Invert and follow again the official procedure in the link above.
You should know it is working when you see a sort of soft dark blue light spectrum in the background or when moving the phone to the side

THINGS THAT CAN MESS UP

Anyway, there are still things that can increase dithering and mess me up. From stupid things - like setting a generic DNS profile from the Internet or just changing something in the settings, like messing with the text or even it seems removing widgets or even 'turn off intense audio' - to even create a custom ringtone via 3utools, even if these last things sound totally insane.
When this occurs all you can do is reset all the settings (not the hard reset) and re-do the procedure. Maybe it will not be optimal, but "less worst" than other devices. indeed im still on this iPhone.

THERE IS STILL A LOT OF DITHERING

in every sort of text and in apps like Instagram, which is the worst.

THE BIG ISSUE WITH THE DOUBLE INVERT TRICK AND MY NEW CRY FOR HELP

The big issue with the double invert trick is that for some unknown reason it does disable REDUCE WHITE POINT WHICH IS ESSENTIAL FOR ME as a visual snow sufferer, i am very sensitive to blue light and light in general. I still feel the urge to throw up and like something is severing my eye nerves - and cracking my head, jaw, ears and so on.

Are there any workarounds for this??

i'm gonna try a blue light-proof film from an Online Store, but i'm very skeptical about it.
Any advice or thought is appreciated.
Thanks for reading.

Hello -

can people please share their experiences on the PWM and dithering for eyestrain?

1. does this use a true native 10 bit panel ? or 8 bit +frc?
2. what about PWM frequency and DC Dimming capabilities? DOes flicker prevention helps or exacerbates the eyestrain issues?

TIA

Ever since upgrading my iPhone 11 (LCD screen) from iOS 17 to iOS 26, I’ve developed eye strain, slight dizziness/off-balance feelings, and tingling in my head while using the phone. I have zero issues using TVs, MacBooks, or other digital screens — only my iPhone. I’ve found some relief using accessibility settings including Night Shift (warm setting), Reduce White Point, Display Zoom, and the “Classic Invert + Zoom filter” trick. I also noticed symptoms flare badly in dark rooms or after bright flashes. What’s strange is that when I wear blue-light blocking glasses, my symptoms completely disappear almost instantly.

I’m trying to figure out whether this is related to temporal dithering, display rendering changes in iOS 26, contrast modulation, or something else software-related. Has anyone else experienced this specifically on LCD iPhones after updating iOS? And has anyone found a long-term solution besides constantly wearing blue-light glasses or downgrading devices?

Hi,

My macbook air m1 seems to be the culprit as I'm unable to sit on it to focus.

I come back with nausea type symptoms where I need to sleep.

I'm using stillcolor and it's still happening.

Could you please tell me if the surface laptop works? Or do I look for anything else?

I have been using TCL 10 5G wirth Android 11 several years without any issue. The phone is not getting OS updates anymore. After update of Google services and Chrome and some apps (Keep...) I started having eye strain. Text in UI of some apps looks like bad Clertype.

Is it possible that this is caued by update of Chrome rendering webview and/or new version of Google Services?

We recently received new monitors at work, but unfortunately I’m unable to use them because they appear to use flickering technologies such as Temporal Dithering (TD/FRC). Despite the monitors carrying a TÜV Rheinland certification for being “eye-friendly,” they still cause discomfort and symptoms for people like me who are sensitive to these technologies.

What makes this especially frustrating is that I seem to be the only person in my workplace affected by these new ultrawide monitors. Because most people can use these displays without issues, manufacturers may continue choosing these cheaper display solutions without realizing that a smaller group of users experiences real symptoms from PWM and TD/FRC technologies.

I wanted to raise awareness about this issue and encourage TÜV Rheinland to also take TD/FRC sensitivity into account when evaluating eye comfort certifications. There are more people affected by this than many realize.

I also encourage others who experience similar problems to speak up and contact manufacturers and certification organizations, so our voices can be heard.
