Does anyone else find it strange that I have several times stated that Motorola G5 Plus and Moto G100 phones are completely eye strain free when used at >65 % brightness, but this information does not seem to catch up at all?

There is always the complaint "oh it's to big for me" or "maybe it's OK for you" or whatever. I have not found any other phone since several years that would work, even those with LCD and NO PWM. Only ones are the old Sozy Xperia ZX Premium and these two Motorolas, when used at brightness levels that have no PWM.

I also have not found a single recent laptop except the Lenovo x280 that would work for my eyes, though I have tried about 20 laptops.

So I also do have a problem with temporal dithering, or whatever it is when an LCD gives severe eye strain even if there is no PWM.

But these 2 Motorola phones I can use 12h a day without even a hint of eye strain. Just like reading a book in natural light.

But nobody is willing to try those?

Motorola just released G200 and it seems to be with LCD like G100 and seems that it could be similarly set up, that it would work as well. A Flagship quality phone with a display that we could use.

Also, the G100 is pretty good phone and now starts to be quite cheap and realidly available still.

Please - try it, return it if it gives you eye strain with brightness above 65%.

If we could get more people who confirm this, maybe we could send a petition to Motorola to keep manufacturing the Moto G series with the LCD?

Any experiences with screens on…

Notebookcheck informs 0 on PWM…but….

I can only use phones with 720x…. pixels

Thanks

What makes you think you can only use 720p phones?

Even 720p annoys in longer use. But that is the smallest amount of pixels that you can get on phones these days. Can't watch TV if picture(any screen) is Hd ready or better. Cable Box is set to progressive 50 hz SD (720x576, p50, no problem) Even with that, if I adjust more sharpness to my Sony TV (set to 0) It starts to irritate and activate my migraine…

    QlaGzr OK. Interesting. Having had the PWM issue for close to 30 years, and researched the topic, I've yet to hear that anyone would have an issue with a higher resolution.

    I had the Sony Xperia XZ Premium that had a small screen but still 4k resolution. I would think it would be simply impossible for anyone to sense the difference, especially if watching the screen from a yard/meter if it is a 4k resolution or 720p, thus I would think that this would be a way to verify that it is not the resolution, it is something else.

    Before I knew about PWM, I also kept playing with display resolutions and scalings, thinking that it could be the source of the problem, but after I learned about PWM and got a PWM free display, I realized that resolution does not have anything to do with the problem.

    But yeah, sorry to say this, there is a large group that has a problem with flicker (PWM, temproral dithering, other sources of flicker) and there is no doubt about it that the problem is the flicker, even very high frequency flicker, like 2500 Hz, which absolutely is not perceivable to the eye. Then there seems be a large group with issues that seem to affect a very small group, like those who have issues with certain driver versions or amount of blue light or like you now, resolution.

    For the blue light, I'm pretty sure it is rather the flicker. For the driver versions, I think it is also flicker. For the resolution - could it also be flicker?

    Problem is that if we have a 1000 sources of problems with the displays, we will never be able to fix the issue because no manufacturer will manufacture a device that does not flicker, conforms to a certain old driver version, has a resolution of only 720p, has no blue light etc. etc.

      I tried the Asus Zenfone 8. It was definitely a significnt improvement over the Samsung Galaxy S21 that I'd tried before. I set it to 60hz refresh rate which enabled the DC dimming. My experience with it on that setting was quite comfortable, and not like that almost aggresive type of feeling I felt from the Samsung. However, there were other issues such as significant colour shifting which caused pink/purple discolouration and banding when the display was moved only slightly. This in itself became really annoying and was enough to give me some eye strain and headaches. Alas, it had to go back.

      I am thinking of trying the Zenfone 6 with its LCD display, though can't really find it for a reasonable price even 2nd hand. This is a phone from 2019 but it seems it was quite rare here so second hand examples and any new old stock are like gold dust. The only other options after that are the giant phones with LCD displays from Xiaomi etc…or the Motorola as mentioned above.

      But what I still can't move on from is that my Oneplus 3 from 2016 wiith its OLED display has been extremely comfortable for 5 years of use. There must be something different in these new OLED panels aside from/as well as PWM that is causing some of us these issues? The comparison Maxx made above is a good one, I find it almost just like reading a book in terms of how non-aggressive it is to my senses.

        I've just found out I have eyestrain from looking at reflected light from the screen. You can test it on paper. So it is the light in my case.
        You can test it by going to the dark room and looking at the screen reflection at the piece of paper, even on low brightness.
        Be careful, i found out that looking at bad screens in darkness may be way worse than doing it in full light. No matter what is the screen brightness. Avoid looking on screen, avoid any light directly from the screen, the screen should be turned away from you.
        To get the best results it makes sense to test it with your worst phone. Compare with the reflected light from normal tech at the same perceived brightness at the same room.
        I am also having problems with new oleds, no problems with old oldes, no matter what the pwm is.

        P.S. This result with reflected light is so weird, I will double check it myself a few extra times.

            If you look at this MacForums post here, you'll see an "Anti-Flicker" option -- but it looks like an Android device and not an Apple one.


            Does anyone know what phone this is? Is it a OnePlus device?

            I have been using Poco X3 Pro more than one month now. At beginning, I had some eyestrain and mild headaches, but now it is all normal and I can use phone without problems. Just to say, I could not use iPhone 11, Samsung 20. These are the phones that I have sent back.

            One problem with the Poco is it sheer size. I would like to try Xiaomi 11 Lite 11, as it is lighter and smaller phone.

            Does someone have experience with Xiaomi?

            To add, I have been also using new MacBook Air M1 few months without eye strain.

              Got the eyestrain at the store, similar to iPhone 11 and slightly better than Samsung 20

                  I've been using iPhone SE 1st gen for 3 years daily and have no strain from it. One of updates in the past caused some strain for a while (in connection with the movement and animations), but now it's good with iOS 15.

                    For me is iPhone SE 2020 one of rare phones that I could use without a strain. Newer iPhones are unusable for me.

                    If they only would be produced in format of 7+ and 8+ phones.

                      My last usable smartphone was the Samsung Galaxy A5. It never gave me any problems. I tried after that a Xiaomi Redmi Note 9S and Samsung Galaxy A51. Both gave me eyestrain and headaches and it was worse with the A51.

                      I don't understand. What has changed in this last 5-6 years in smartphone technology that we have to suffer these symptoms? Why does the Redmi have milder effects than the A51, when the A5 is also an AMOLED and it never gave me any problems?

                        DiegoRojo this is what I am trying to find out.
                        Would you like to try out if a reflected light from the screen does the same?

                        I posted here a couple days ago:

                        Mrak0020 I've just found out I have eyestrain from looking at reflected light from the screen. You can test it on paper. So it is the light in my case.

                        I have a hypothesis about this light, checking it out right now.
                        In the last few years manufacturers were fighting for increased brightness and readability outdoors, under the sun, for increased amount of colors. Most probably some of these improvements lead to the eyestrain. It is not a well-known characteristic of the screen, visible in the screen specs. It it something subtle within the screen, can be found out only by disassembling.
                        By disassembling ips screens, it was found out that a part called polarizing film makes an impact to the problem. But it is not a source, its replacement leads to very subtle improvement. There should be something else.

                            @"Mrak0020" Thanks for your reply. I will try this later after i return from work. I agree with you, i feel like symptoms are a lot worse when using the phone when it is dark.

                            After reading the last posts in this thread, i believe we can agree the problem is more complex than reducing it to PWM issues and display type. As i said in my previous post, the Samsung A5 never gave me any problems even after hours of using it on the same day, while the Samsung A51 gave me the worst kind of headache i've experienced watching a screen. And it's strange that the Redmi Note 9S, being an IPS LCD with supossedly no PWM flicker, or at least flicker at higher frequency than most OLEDS, it's in a middle ground in terms of symptoms between the A5 and the A51, both AMOLEDs with bad PMW from what i've seen on some reviews. So Wtf 🤣

                            I will try using the Redmi for a few more days to see if my vision somehow adapts to this screen. If the symptoms don't lower i'll try to find another phone (Any recommendations?)

                              Oh you don't even imagine how far it is from display type and pwm and things like that. I am doing all the research in another language so there's little of it on this forum right now; but there's a community of people who face this smartphone problem and a lot of tests are already done. For me old Samsung Note 5 (super amoled with low pwm rate) is the last normal phone, and iPhone 11 and Xiaomi with ips bring me a lot of pain immediately.

                              No recommendations right now, unfortunately. Only one: avoid pushing through pain, bad phone will just damage eyes more and more. If your redmi has something like "reduce contrast" in settings, try it, it is helpful on some devices. Contrast has something to do with this, but not per se, it just messes up some physical qualities of this light.

                              Ledstrain generally is visited by people with other types of problems, so this smartphone problem is less covered here. But I have to say it is not exclusive on smartphones, it has something to do with the basic screen technologies and eye sensitivity to this specific kind of damage. So some people have the same problem with notebooks, monitors etc. It is definitely most present in new tech (starting from 2017), but could be found earlier sometimes.
                              It is definitely not connected to any eye pathology, a lot of people I contacted have been to ophthalmologists. Me too, I had a complete checkup with a lot of tests and my eyes are absolutely healthy.
                              Neither it is connected with BVD, discussed here; most probably this light makes eyes to immediately excessively converge reflectively. But that is only a top of an iceberg; somehow it makes little red blood vessels to appear or break immediately, leads to light sensitivity (hopefully by damaging only cornea and not a retina, but it is impossible to define) and so on. The longer it is used, the more damage a person feels, but muscle pain from excessive convergence will slowly go down.
