I would appreciate the input. The working title I have currently is:

Apple: Please stop using temporal dithering and be mindful of how flicker is implemented

Thanks for this. I am happy to pitch in money too as is impacting my career.

My only concern is we don't know Apple is using temporal dithering. Some evidence here suggests it could be: https://www.reddit.com/r/macbookpro/comments/gkneso/disable_p3_color_gamut_to_reduce_eye_strain/.

It could be some other kind of flicker we don't know about and calling it "temporal dithering" is the wrong term. Definitely get on MacRumors forums. I will spread the word too.

    One reason I believe apple still uses temporal dithering is due to this tweet (from Rene Ritchie):

    XDR Display: It’s a 10-bit pipeline to an 8-bit panel, but uses temporal/spatial dithering and other ‘tricks’ to output 1 billion colors in a way that’s virtual indistinguishable Terrific HDR, very little blooming, manual refresh settings for PAL/SEACAM, references modes!

      I'm also willing to put my money where my mouth is. If there is a workbench I could create to test for temporal dithering, I would definitely buy whatever is necessary pending it isn't in the hundreds of thousands of dollars.

          ryans I emailed him to see if he has ideas for a test rig. I halfassed a YouTube channel for e scooters long ago, I will revive that for display testing if I can get this setup.

            Very good idea, i am in contact with a journalist about this and have launched a survey which got about 150 reaponses

            I think there should be an option on their products: Binocular vision disfunction - turn on. This will disable dithering and all causes of display flicker.

            I developed a testing regime which I detail here. @JTL has his own capture card/software also. However, this is limited to testing if external ports have dithering, not the display embedded within a laptop.

            I never use my capture card anymore. It taught me that there are many other sources of discomfort which do not use dithering, and that in some cases dithering has actually made setups more comfortable to me, not less.

              Seagull That's very interesting!! I wish I knew of an instance where temporal dithering caused me comfort.

                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.

                                        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?
