Patoli Yeah, the coating can definetely be a problem. I own Benq PD2700u (still did not sell it, hopefully soon)
and it is generally an ok monitor if not for the terrible, worst I've seen antiglare film, which is very very grainy and this graininess makes the white light shimmering and blinding even at low brightness. I have some other LG 4k, which has a different problem, but the coating is better (still grainy, but not as much) and it does not blind me.

OTOH, you can try a standard advice: try a VA monitor. Some people report that VA is nicer on eyes, and I confirm it too (but effect is weak). VA are kinda terrible in many ways and nice in some other ways (especially for watching movies).

      EyeDiscomfortCertificate Yes, man. It's grainy, this is the word. It's weird and the very bright led reflection in the center is terrible.

      I also asked to my fried to check and the said that his Dell notebook is like that, but his LG ultrawide IPS doesn't have like all old ones. I asked him to take to my home his ultrawide for me to see with my eyes.

      I like VA, but it depends on panel. My Samsung TV is excellent without black smearing, but most of monitors are awful. Dark images are bad and black smearing is hell. And also, if the antiglare coating is one big reason for the problem even the VA monitor will have this problem.

          Patoli No, for some reason VAs have often better coating and also due to higher contrast the coating deficiencies are not as obvious. But anyways, if VAs do not fit your requiremnts, yes you should avoid it.

          BTW Dell 24 QHD is a more premium professional product, no wonder it has better picture quality. Generally higher end Dells have the best coating in terms of grain. But cheap 24 FHD Dells - who knows what they put there?

              EyeDiscomfortCertificate I can't understand that. S2721DGF, S2421HN and P2423D all different models with different prices and crap coating. I believe that this new type of coating has better light transmittance.

              I would like to know if all monitors that use matte coating received this kind of coating post-2018.

                I asked for my brother to bring me his Dell VA panel SE2216H releases in 2015 and it was fine. Asked my friend to bring his LG Ultrawide 29WL500 releases in 2019 with IPS panel and it was ok. A little bit grainy the reflection but not near the P2423D.

                I returned the P2423D and bought a LG Ultrawide 29UM69G that was released in 2019. I searched a lot of videos to see at least the reflection characteristics and found that 29WK600 from 2018 was more like the Dell that I returned and the one that I bought was like my previous Dell.

                And that is it. The antiglare screen seems almost the same as my Dell and the image quality and characteristics not so distant. I've been using and no difficult on focusing, no strain, no eye pain, no headache and stuffs like that.

                Something very weird has been happening since 2018. I don't believe that is only the antiglare screen but it plays a role. I solved my problem for now with 2017 stuff but next time I doubt that I will have another chance. I would like to figure out what are the problems and how can I discover before I bought.

                  Patoli Your model is 2021. What I've saw is that this hell started around 2018.

                  I think the hell started 2011-2012. Win Vista with default ClearType font (then most tech people learnt what is font anti aliasing), moving from LCD/TN to IPS/VA, moving from CCFL to LED back light, MAC discontinued TN laptop monitors (tho that was 2009-10 I think), pushing for higher brightness (just a marketing thing), more colors support (wide gamut, vivid colors bs), changes in drivers/dithering (I think first complains were with Intel)…

                      daniel_mate Maybe. Back these days I never experienced that. I faced some monitors and different systems but I never imaginated that I would suffer something like this.

                        daniel_mate My 2011 Macbook has a TN in it and it works fine, makes me wonder if IPS is the problem but some on here say theyve had problems with new TN panels too I guess

                            wlmsn Probably nobody of us expected this to happen 🙂 I'm with this issue for ~9y. Over the years I realized that glare and high contrast are my main problems, refresh/flicker irrelevant. TN being the oldest technology has the worst contrast, washed out colors, lowest brightness etc. I've tried lot of different monitors in the recent years and for me nothing compares to TN, tho even between TN models some feel better than others (I think mostly due the brightness or type of LEDs they use).

                            Weird example for me is I've been using iPhones exclusevily for the last decade, I can't tolerate them however once I apply Skinomi mate skin on them, I have no problems. It feels like it replaces their display with a TN one 😃 No more glare and it reduces the contrast, has grainy texture, colors became washed out, it almost blends with the environment like a paper, feels like e-ink display

                              The problem is not the panel but the timeline. I used all kind of technologies without problem. Even TN is in the same vibe looking for more brightness, colors, refresh rate and everything else. Glare was not a problem for me because I use since always smartphones with front glass and glass screen protector, my TVs are glossy and semi glossy. It seems that this grainy scattering of light that recent monitors are using is that what bothers me.

                              One point that the fellow friend touched is that refresh rate or even flickering is not relevant and that is true for me. My previous monitor was 60Hz with 6 bit + FCR didn't bothered me. Before that most of us used monitors and TVs with flickering and it was OK.

                              The thing is crazy for me to buy something released in 2017 to solve my problem. The future will be a real trouble.

                              Hello

                              Sorry to bother you, I saw a comment that you made and got me confused

                              Patoli I returned the P2423D and bought a LG Ultrawide 29UM69G that was released in 2019. I searched a lot of videos to see at least the reflection characteristics and found that 29WK600 from 2018 was more like the Dell that I returned and the one that I bought was like my previous Dell.

                              And that is it. The antiglare screen seems almost the same as my Dell and the image quality and characteristics not so distant. I've been using and no difficult on focusing, no strain, no eye pain, no headache and stuffs like that.

                              You bought the LG Ultrawide 29UM69G and what happend?

                              P2423D similar to 29WK600 and P2317H similar to 29UM69G is this what you're saying?

                              Here is my story: mnqrKI6.jpeg (2708×2805) (imgur.com) I posted this in 2020...

                              Then to continue, I sold it, bought 1 AOC VA 2020 CQ27G2 ( returned ) and a Lenovo G32qc-30 VA late 2022 model and returned it recently. Now I stick to my old tv glossy monitor.

                                  BlasterFX It was exactly like my Dell P2317H from 2016. No eye strain, no problem of focusing, same kind of reflection.

                                  But it last until yesterday. I updated my Windows 11 to 22H2 and at the moment that the Windows started I noticed something different, My eyes got tired quickly and had some eye pain. It's defficult to even stare.

                                    mike Yes, for a short period of time. I didn't feel anything special.

                                        mike

                                        I have to say that recently I realized that Mike's been right all the time, the problem is in us. But patching one eye had no effect on me so I took Mike's wonderful idea to another level: I am now patching both eyes! No eye strain! Problem solved!

                                              machala I have to say. Part of the problem is us because most of people don't care about monitor, GPU, driver, Windows or whatever. But something changed hardware and software level that nobody can explain. It was ridiculous see in other topic that even Microsoft people suffered with strain after updating to 22H2 version.

                                                  Patoli
                                                  Yes, and that's exactly the reason why I will never accept the problem is us. There was a change, there is a difference how things are today compared to the past. We are more sensitive, yes, for others the problem does not get past their pain point. However, I do not believe the problem is non-existent for many other people as well. They probably suffer, but are able to endure it somehow. But it does not mean it won't have drastic effects on their health over longer periods of time. The problem should be exposed to media, I just don't know how to do it.

                                                  For me the final proof is my wife: she never felt ANY of the issues I had previously (she was even kind of making fun of me), but in recent years she's started saying for instance that "this screen's picture is not as pleasant to look at as the old one". I of course see very clearly that there seems to be flicker and the picture is terrible. For her, it's just unpleasant. Something's happening, that's for sure.

                                                      machala I have very clear that the main reason is some change in the backlight emission on the new displays, because it cause me not only eye strain but also skin pain. I think it is due to a much higher intensity of the light, specially with oled and PWM screens, where we always receive the maximum brightness of the displays during a percentage of the time. That level may exceed the pain threshold of the most photosensitive people. I could stay in front of old displays for days without any pain. Eyes sense light level on a logarithmic basis, so the peak brightness can be 100 times or more the lowest we perceive when we set it to darkest.

                                                          The real light we receive from a PWM screen is equivalent to setting the screen brightness to maximum. You can test how do you feel in these conditions to detect who is affected by this cause or by others, If setting the backlight brightness to maximum makes the symptoms worse.

                                                          Not true, I see unstable picture on the same screen (old monitors) when I use newer graphics cards (and motherboards seem to have impact on this as well). Apart from other people that are getting "symptoms" after some time of use, I, in some cases, immediately see the picture is unstable.

                                                          I'm not saying backlight cannot be problematic, but it's definitely not the main cause for me.
