Why is my iPhone 14 Pro causing headache, nausea and eye strain? PWM Complaint...

The refresh rate has absolutely nothing to do with Pulse Width Modulation (PWM) and the problems that people with this sensitivity have. None. And as I've repeated to you several times by seeing a doctor, let's say an ophthalmologist, it creates enough data to be able to get a better idea of how many people have the issue and to justify spending money to research the matter. It also builds a database of people to do research and testing. It would also provide the opportunity to form an organization of people with this medical issue so that facts can be collected and posted, etc.

Incorrect again, the variable refresh rate can and does affect users. They say their iPhone 12 Pro doesn’t bother them yet their 14 pro does. The main difference s the display they are not identical. The 14 Pro has a variable refresh rate, indicating it changes its rate continuously. This can create eye strain.

Please post these websites.

If refresh rate was part of the issue then the people with the sensitivity would never be able to watch existing televisions and monitors that are not LED.

The sensitivity is to Pulse Wave Modulation and refresh rates are not involved in that technology. Poor refresh rates can cause eye strain but faster is better for that. And faster is better for people with a sensitivity to PWM. If you go back towards the start of this thread one of the first posters specified that he wanted OLED screens with a 2,000 response rate which would eliminate the problem for everyone. It would also drain the battery in about 80 minutes.

Using maximum brightness and adjusting the white point helps some people. A faster refresh rate could help people, slower would make it worse.

Nope, just saying incorrect doesn’t mean anything. Early in this thread one person mentioned a website that listed the response rate of various screens. A variable refresh rate that can go to 120 would alleviate eye strain, not make it worse. But again, it has nothing to do with PWM which is what this thread is supposed to be about.

Exactly my point the iPhone 14 pro has a variable refresh rate meaning just because it’s rated for maximum of 120hrtz it can also go as low as 10 hrtz. Which would explain why people with sensitivity may be affected by the 13 pro and 14 pro models more than a 12 pro. Because the refresh rate can be much lower depending on what they are viewing.

That was done at the start of this thread but yes when I get time I will repost the site that measures PWM response rates (few do). It isn’t a syndrome and yes, eye strain is part of it but the symptoms go way beyond that. Lots of things cause eye strain, just looking at a screen too long will cause eye strain.

As stated previously, you will also need to avoid premium smart phones from all other vendors as they also use OLED screens sourced from the same manufacturers.

Thats why Apple offers a 14 day return policy - so you can make sure their product is appropriate for you.

Thanks - this is all clearly understood. I believe the main purpose of this thread is to bring this issue to the attention of Apple so that they could perhaps address it somehow in the future releases.

The display put in the iPhones are custom build for the iPhones. They are not a standard display on the market. Apple makes the specs and then finds a manufacturer to meet the specs. Just as they recently switched manufacture to meet the specs. An example is no other phone has the same brightness nits as an iPhone not even a galaxy phone has the new displays even tho they manufacture them. They are made custom at Samsung based on Apples specs. So it would be incorrect to say they don’t have a say in manufacturing the display as they play a major part in it.

You really need to do some research on displays, manufacturing, etc. No they are not customized for the iPhone other than the size and some security features. They are the standard displays used on all other smart phones with OLED screens. Apple does not make that specs and then find a manufacturer especially with displays as there are so few companies that make them. And you really think Samsung will build a better display unit for Apple than they have in their own devices?

Apple, LG, TSMC build their display units and offer them to other companies. The other companies can ask for minor changes for their devices as long as it does not change the basics of the unit. No display company is going to completely retool their factories to do a custom unit.

Apple can specify an OLED unit that has say a 1000 PWM response time. Samsung would need about a 3 year lead time to custom make it and the cost of the display unit would be about 3 to 4 times the current unit thus making the iPhone probably $500 more per unit. But each of these units would have about a maximum 5 hours battery life unless you are gaming or watching videos which would drop it to 2 hours. So how many of these units do you think Apple would be able to sell?

I’m not sure where your getting your info from, as it is incorrect as the display on the iPhone is one of the best on the market and not even galaxy devices which are manufactured by Samsung have them. For the fact no other phone on the market has the same peak brightness! There are many articles that explain this. Apple chooses a display to meet there standards if it doesn’t they will find competitors to meet them….https://www.sammobile.com/news/iphone-14-pro-brightest-panel-from-samsung-even-galaxy-phones-dont-have/

The peak brightness on the Pro Max is a little higher but Samsung won't release their new Galaxy's until March at which point their screens will probably surpass that. There aren't a lot of competitors to choose from out there so if Samsung, buy far the largest supplier currently can't meed what Apple is asking for then they will suggest they buy from someone else. Apple had to bail out TSMC so they would not be able to come close to supplying all the displays that they need.

But you seem to believe that Apple can write "specs" for someone to put a fusion reactor and then someone will supply it. They do not design a display screen and then give that to Samsung to build it. It is not new technology to have an incremental increase it brightness on OLED screens. They don't have to retool to build it. It is an incremental improvement. And this isn't the first time that Apple has had a Samsung screen that was better than what was currently being sold by Samsung. But that is because of different release cycles. Samsung releases in March and Apple around October.

But Appel does not DESIGN OLED screens. They negotiate with Samsung for what can be done within their production cycle. They cannot come up with a "spec" for a 1000k PWM response OLED display that has the same power draw as the current display unit. Because that isn't possible.

I don’t understand your point? Are you trying to argue what I have stated? You seem to be rude and targeting me. Apple will be able to fix the issue in the future. I’m confident in Apple that they will see the issue and address it. Pwm is a display issue, but Apple is not speechless when it comes to their customers. Again in the article it explains that if a display doesn’t meet apples standards they will find a manufacture that does.

Did you actually read the article you posted here? The changes that BOE made had nothing to do with the design of the display, it primarily had to do with BOE cannot meet Apple's production needs and they used a cheaper material for transistor film that did not meed the contract that they had with Apple. It did not say that Apple designed the display. And you missed an important part, Apple was only trying to use BOE so they could negotiate a lower price from Samsung and LG who pretty much control the market. If they can't negotiate a lower price with those two why do you think they can force them to design a new display unit with completely designed PWM. And how do you propose they solve the battery issue?

I am not targeting you, you are the one who is making these posts that don't match reality. If this issue is fixed in the future it will not be done by Apple. It will be done by Samsung and LG. I never said Apple was speechless and I'm sure that they have had discussions with all the display makers regarding the situation. But until all of the manufacturers involved have some reasonably accurate idea of how many people are affected by this there isn't much of a chance that it will be there principle talking point in designing in new displays. And all the display parties involved would love to see a battery breakthrough occur which would then make it far easier to deal with the PWM response rate issue. That is what is really stopping Samsung and LG from dealing with this issue.

hey everyone!

This is not about the screen, Headache is caused by the cellular antenna inside the iphone and amount of data you use. I notice that when I watch YT I feel nauseous and facial numbing sensations occur. Imho it’s the electromagnetic frequencies.
