What has anyone heard and seen regarding the early hands on videos with the iPhone 14? Have yet to see a reviewer mention it, was hoping MQB would. Saw a bit about how Huawei boasting that they have upped the PWM frequency to 2000+hrz with a BOE screen. Any potential for this to make it to iPhone, given they (still I believe, after the cheating) are supplying Apple with displays for iPhone 14?

MTNEYE Saw a bit about how Huawei boasting that they have upped the PWM frequency to 2000+hrz with a BOE screen I wrote about that here and it seems things may be different than as advertised.

The Mate 50 Series uses a OLED display with 1440 Hz PWM Frequency. Sadly there is currently not one clue of a better PWM implemention on the new 14 Pro and Max. BOE should only supplie a small part of the displays for iPhone 14. So i don`t think that the iPhone 14 could have a PWM Frequency above 1000 Hz.

I've preorder the iPhone 14 pro, so il will give you a feedback in 10 days! Now i am using the iPhone X with iOS 14 with zero issue.

I should be receiving the 14 Pro this Friday (16th) and have the Opple lightmaster so I should be able to a) tell you if it works for me and b) get some readings.

RulerofNothing The Mate 50 Series uses a OLED display with 1440 Hz PWM Frequency The Poco F4 GT was also claiming to use a "1920Hz PWM frequency" but as I wrote here , the situation seems to be different, and its unclear what they're even referring to.

JTL are you talking about the F4? ThePoco X4 GT is supposed to be an IPS LCD display

JTL

francerex Yes, pardon me for listing the wrong model by mistake.

francerex

JTL I just ordered the X4 GT, should get it wednesday, and you got me scared for a moment 😃

MTNEYE

Lauda89 awesome! looking forward to it! I was thinking of getting 14 pro (not max)

MTNEYE

markdotpeters5 YES that would be great, some actual readings! I have trouble with the 12mini/XS max at everything but 100% brightness, had a 13 mini that had trouble even at 100% brightness (still PWM dims at the level)

MTNEYE

JTL yeah im taking anything from Huawei with a grain of salt and a proxy server

iphone 14 pro uses an LTPO screen and I have no problems with my apple watch LTPO screen. Could there be some luck this time..

markdotpeters5

[deleted] That alone won't be enough. I've had loads of problems with LTPO screens.

Lauda89

Bad news guys.

First impressions are not good, I have "brain fog" / disorientation.

Consider that I use without problems: iphone X (ios 14), pixel 4a and samsung A52.

I will try to adapt in the next week, otherwise I will return it and come back with my iphone X which still works very well.

EDIT: I am trying the iphone 14 PRO!

Lauda89 Thanks for sharing… but that was expected.

markdotpeters5

Lauda89 Same 🙁 Sticking with the Mi11 for now.

Keye21

Lauda89 Im So glad you have mentioned the brain fog! This is one of the main symptoms for me. I have not heard anyone else speak about it. But If I try and keep the phone it gets worse over time.

Lauda89

NewDwarf Honestly, I was hopeful. I have never had any problems with OLED devices.

Let's wait for the notebookcheck review to see what frequencies this PWM uses.

drima55

Lauda89 You have problems with Iphone 14 Pro, when there is no problems with Iphone X? This is strange because X is guaranteed to have a lower PWM

markdotpeters5

drima55 I can only speak for myself, but I seem to have more of an issue with the variance in the PWM rate rather than the actual rate itself..

So if the rate is lower it could still be better for me as long as it's stable. The 13 and 14 range are all over the place.

Lauda89

drima55

They are two totally different panels though! The iphone X has a fixed PWM at 240hz and a less bright screen with a fixed frequency at 60 hz. This one has 2000nits of maximum brightness, a refresh rate ranging from 1 to 120 hz, and a PWM that looks dynamic.

Then consider that there is also different software, ios 14 vs. 16!

markdotpeters5 I will return with the iPhone X for another year, then I will try again with the iPhone 15 next year 🙂

Keye21

drima55 Well I assumed the same. But all the phones since the X have given me migraines, vertigo, brain fog etc.. ive tried X, Xs, 11, 12 pro, 12 pro max.. and returned them all (several times, from several attempts) but the 13 pro max was fine, it didnt give me a headache once in a space of a month using it every day as main device. (I did return due to brain fog) and that has a low refresh similar to the XS max which was awful for me.

So last week I tried the 13 pro and within a few minutes, I felt a dizzy, went home and had a headache. so frustrating. Ive felt rubbish since. The pro max's effect me less but the small ones with a higher refresh give me the worst headaches. So I think it just varies for everyone. Currently using an iPhone 8 plus lol.. I was hoping the 14 pro max with the LTPO screen would be better but n thinking other wise. 🙁

markdotpeters5

Not good news I'm afraid. I'll be returning the 14 pro. Headaches and discomfort within a few minutes of usage

MTNEYE

markdotpeters5 Thank you so much for this, saved me a whole order return hassle!

Vaggbaba

markdotpeters5 how did make that?

drima55

markdotpeters5 Do you have no eye strain with Mi 11 Ultra?

markdotpeters5

drima55 None at all. it has DC dimming.

markdotpeters5

drima55 ooh, sorry realised I mis-read your question. I've never tried the Mi11 ultra, I have the Mi 11.

Lauda89

Had an iphone 12, had to return it because it was impossible to use. big headaches and eye strain no matter how much i tweaked the settings.

heard the 13pro improved this a bit and maybe the 14 could work?

im using an 11 now with no issues.

qb74

blokes444 Great to see that Apple is somewhat moving the PWM frequency up compared to other manifacturers which are stuck at 480-240 (still way too low, easily spottable)

With how it's progressing, maybe the iPhone 17 might have an OLED that has decent PWM handling 😃

(hopefully other manifacturers won't follow this trend… lol)
