I mean I think you get acclimated if you have the phone for a while and don’t have like epileptic type intense reactions, but shifting back I felt it in limited periods of use in my eyes... but still can’t be good for one if you detect you experience a difference. Long term
The crammed scaling was bothersome too. 7+ was my pseudo daily to pair with series4 on iOS 12 as my x never left 11.3 , and going back to x / 4.7” ish scaling was bothersome
But I’m no doctor haha just a father of a dogg
And I didn’t like the blue shift or the finicky angles compared to my Xr either
One will have to pry lg 4K oled tv’s from my cold dead hands but I can deal without on phone. The xr is a great “im gonna upgrade anyways” device there is no longevity. But I’m now down to Xr and SE (2, one on 10.2 jailbroken other on iOS 12 as a backup)
It’s a ‘cracked out’ feeling I don’t care for
And hunting passively , not knowing but feeling it on my eyes, even tho the screen looks crisp color wise
I’m glad to have what I call “real” True Tone too. Since True Tone and oled sucks so much more often than not
Oled True Tone looks like vomit most of the time and 90% night shift vs the intended purpose of True Tone to feel like a neutral white in most lighting
Works spectacular on iPads since it’s inception and 8+ and Xr
In its current form it’s a bust on oled imo
Thanks.. good info. From that table, it seems even LCD screens notebooks are using PWM, so does it mean PWM not limited to OLED? Previously, it was reported that LCD use analog dimming which actually dims LED backlight to reduce brightness but OLEDs use PWM.
Also, what's the relation between brightness level and PWM? And if LCDs can dim its backlight OLED without PWM then why not use the same technique in OLED screens?

I want to add.. I have had to abandon the MBP line this year because of this issue.
It’s not just strain, it actually makes my eyes tired and or jittery causing slight anxiety after short periods of use.
Have switched reluctantly to a Lenovo X1C HDR Flicker Free display and can use that for hours without issues.
It stinks because now I don’t have my iMessage/FaceTime/Airdrop solution on PC.
Guess it’s one way to start weaning myself off the ecosystem.
And no, I will never, EVER, go to Samsung Touchwiz.
Testing out a Pixel 3 now..
The boredom is killing me with it!

This. Did they just use the same algorithm and parameters without taking into consideration the different nature? It can’t be. But on the other hand True Tone is amazing on LCD and pure vomit on OLED.
Yes, but the few phones that use PWM free OLED have color shift issues at low brightness.
It's not limited to OLED. More or less all LCD displays used PWM in the beginning. It's a good way technically to manage brightness of LEDs no matter the type (regular or organic). It was determined to be problematic with the flickering though and for the past 10 years a lot of displays have gone with analog dimming. PWM can cause EMC issues too. Many modern LCD displays still use PWM but any good PWM implementation should be in the 20000+ Hz range. Not below 1000 Hz for sure. Some LCDs unfortunately still use low frequency PWM.
TVs also do a lot of processing to enhance motion performance, like black frame insertion, that cause flicker even on LCD displays with flicker free backlights. Finding a truly flicker free TV can be a nightmare but thankfully many TVs allow users to disable motion processing.
For OLED it's still the only technically good way to do it. There are PWM free OLED displays but they have color shift issues at low brightness levels since LEDs tend to shift color when they are very dim. For a white backlight that's not too much of a problem, but for RGB pixels it is. It's still early days for OLED compared to LCD. The technology isn't very mature yet.
i am experiencing on and off headaches last couple weeks and I am not sure if its related to the Xs Max i just got or not. I had been using the X last year and it was fine. Has anyone go into the store and able to swap another unit for this reason? Will replacement unit resolves the issue?
I had the X last year but the Xs Max was messing with my eyes big time. Changed to Xr and all good now...
I bought the Xr on Nov 16, yesterday I decided to return it and try the Xs Max. Big mistake, noticed the eye strain shortly after use and the color shift when looking at an angle was awful. It went back today. Fortunately the verizon store still had the Xr that I returned so they let me buy that again. They normally only allow one exchange. Sure the Xs Max was a nicer phone but just couldn't deal with the screen. Learned the hard way, out $50 on the restocking fee but couldn't be happier to be back to the lcd screen.

Wow, look at the PWM of the XS vs. the XR in this video:
Howcome you dont see the PWM like that on the XS when you look at them at the apple store?
