Seagull Hello! Excuse me for offtopic, do you mind listing other sources of discomfort and dithering setups that helped you, in brief? Or maybe you listed them previously and have a link to that post?

    I don't know if the problem is the dithering, if it affects in part or if it doesn't affect at all. The only certainty we have is that most of us can use notebooks without GPU drivers or in safe mode (for MACs), right?!

      Lauda89 Nope, even that is not the common thing.
      There are at least few different separate sources of eyestrain (PWM, my problem, temporal dithering or whatever affects many people here and correlates with GPU drivers/safe mode). I am not sensitive to the most thing discussed on this forum.
      Petition might help with the third source.

        Mrak0020 if your problem is just related to PWM, you have to buy a products that don't use it. There are many sites that give reliable information on the use or not of PWM: RTINGS, tftcentral, notebookcheck, laptopmedia etc..

          Lauda89 It is unrelated. I might be unclear with my list, it is:

          1. PWM
          2. my problem (hypothetically connected with the insides of a screen)
          3. dithering or similar thing that is solved by the safe mode/drivers/etc.

          They are separate and there's a chance there's more.

            Mrak0020 I understand, but PWM is an easily avoidable problem. We can't complain about iphone 13 or macbooks because they use PWM! They might tell us: "you are probably PWM sensitive, avoid this product list" and they will close the problem in two seconds.

            What we should do is to buy the Imac 24" M1 which does not have PWM and see how many of us have problems. If we all have problems then we can take that product as a reference and plan to go deep into the software problems.

              Lauda89 Oh. I get it. Yes, sure.
              But there will be two problems left, which are number 2 and 3 in my list (and again there's a chance to find more). In my case there is something in the screen of iPhone 11, which is PWM free, but not in software, and I have no idea how to differentiate between those cases number 2 and 3 right now. Unless a person made a lot of experiments and found a clear connection (or an absence of one) with software.

              Mrak0020

              I had a Benq BL2405 monitor that only useable with a dithering GTX 660 graphics card,

              As for other sources of discomfort:
              Polarised light,
              LCD Inversion,
              I also seem have to have some issue with blurriness/sharpness, but I am not sure.

                Serious question, has a change.org petition ever achieved anything?

                  ensete very good question indeed. I am not sure. The way I see it, the more attention it brings, the higher the possibility it can catch the eye of publications that bring the issue to light.

                  Take for instance the silly petition to make Will and Jada smith stop oversharing their lives. That. That there caught media attention because of how many signatures it got 😅 .

                  I'd love it if larger YouTubers covered this as well.

                  There's got to be people searching "headache iphone 13" on Google etc, right? I mean that's how most of us found this place. @Slacor any idea how folks are finding us?

                  I wonder if we could advertise the petition using Google AdWords, Facebook Ads, etc. I'd gladly pay.

                  We could even make a simple static website explaining our issues that links to our petition, this forum, @jen great website, @martin website on heterophoria, the 150+ page MacRumors forums, etc. Could further on send it to news websites.

                  Any thoughts? I'm a little short on free time at the moment.

                  Awhile back I created a "Call to action" template that can be used.

                    Slacor Awhile back I created a "Call to action" template that can be used.

                    For advertising the site to users who have related issues I could potentially see such a template being useful.

                    For outreach to companies I disagree this is an ideal format. I realize this may be a bitter pill to swallow, but what I think is really needed is some of our own empirical research with some probable root causes properly articulated so engineers and other investigators can't shot us down with "we checked with our expensive sensor thingy and the screen itself doesn't flicker, so therefore there is no eyestrain" and other weak arguments.

                      ensete I'm not sure, but I kind of get the feeling that change.org petitions are more of a "marketing" exercise and a "feel good measure". One thing I do know is they like to subscribe you to marketing email lists 😛

                      I am beginning my journey into research as we speak. I am tallying up the cost to capture temporal dithering in the act. That alone doesn't necessarily do anything, but it can be a great A/B test for some as I get to test more and more devices. For instance, I can use an older iPad Pro running version X but can't use the new iPhone 13. Does one use FRC on a lower bit panel to mimic a higher bit panel (temporal dithering)? I hope to find out.

                      I am still working on the test process, but I believe I have nailed down the hardware I need. This is going to be quite expensive.

                      I still think this petition can't hurt. If anything it can help bring more of those who face the issue to forums such as this. We might even end up getting some specialists to chime in as the population grows.

                      I'd still appreciate some input on the title.

                        Clokwork I totally agree, and despite my problem is not connected to dithering or flicker and there's no way to capture it yet, I see any additional media resonance as a step forward. We just need not to make mistake attributing all the cases to one single problem (doesn't matter which one) and collect all the empirical evidence.
                        A petition can't hurt.
                        (But eyes can. Dumb marketing slogan created, lol)
                        Also any systematized research similar to one Jen made can help a lot.

                        Can we do this petition not just to Apple but to all manufacturers? I believe many of us are having problems with a huge range of devices. The manufacturers are doing things behind their hardware and software to 'manipulate' the display signal. They succeeded in making those 'things' an inherent part of the product or technology by simply ignoring, not informing or announcing to the consumers in any way, let alone giving us an option to control / turn it off. It is sure a violation of consumer rights.

                        We members of this forum can set up a petition together and spread the words to make this issue known (and sign. of course, lol). I already thought of some results that we expect and can put in the petition content.
