jordan before you do, let me tell you that I still have issues with it from time to time. At the moment I do not use the sRGB setting but the gaming mode. Seems to be better for now. However it is better than the other CCFL screens I used before.
I want to try the Dell 3008wfp. That has 8 bit and no FRC.
But first I will wait for the MSI MPG 321URXDE 240hz QD-OLED.

I cannot stand LED backlighting. It gives me throbbing pain. So I resort to CCFL screens for now. But I tend to get dizzy a bit ( at least better than the eye strain ).

Motherboard is an old Asus prime b250m-c.

      async Finally something that feels like messing with color profiles. Seems somewhat better.

      Yep, seems like it generally improves OLED iPhones, mostly because it disables HDR which is usually always-on on OLED iPhones even in the system UI (for example, Control Center volume sliders and the clock on iOS16+ lockscreen both use "brighter than white" shades of white, and double inverting is able to stop this)

      Also, it finally lets me fix the super bright HDR white used in the screenshot flash that always feels like it's blinding me if I take a screenshot in a dark room. BTW, "Reduce Transparency" also disables the HDR white in specifically the screenshot flash (but not anywhere else). But with double invert I can keep transparent backgrounds on if I want while still disabling HDR here and in other places too.

      It still seems like the one device it had the most noticeable and significant effect on is the 2018 iPad Pro. I was actually super shocked when I first tried it (I discovered the technique while messing around with the settings on that device) because on specifically the 2018 iPad Pro it seems to stop the "false 3D" effect in tons of places. Also, very wide or very long elements in the UI, like the search bar in Google Drive in landscape mode, become a lot easier to see all at once instead of only being able to focus in on a small segment of it. This was on iOS 17.1 I think.

      Unfortunately on newer LCD devices like SE 2020 it doesn't have the same effects, SE 2020 has one of the worst "false 3D" effects I've seen on an iPhone even on stuff like the home screen icons against the wallpaper, and double invert doesn't change it. I've been only been able to get as many changes as that on the 2018 iPad Pro.

          deepflame on that u2711 make sure it's set to 8bit otherwise 10 will use frc. another one I was considering is the dell u3011 ccfl monitor.

          That rtx 4060 could be causing issues too, some newer gpus dither regardless of native color depth.

            Just got an M1 MBA, unfortunately I still experience eyestrain with Stillcolor enabled. Trying to change other settings now, see below.

            And also ordered a M2 MBP 13“. Lets see which panel…

            @DisplaysShouldNotBeTVs

            Can you perhaps post a list of bullet points for all the modifications you made for less eye strain on your M1 MBA/M2 13 MacBook Pro?

            This thread is getting kinda long…

            • Disable dithering with Stillcolor
            • Disable uniformity with Stillcolor
            • Betterdisplay: Stream Display with integer scaling (perhaps post a screenshot of the exact steps you took?)
            • Disable fontsmoothing
            • Disable truetone and nightshift
            • Standard colorprofile (?)
            • Keep the brightness above ~ 70% with BetterDisplay to avoid the high frequency PWM flicker?
            • Adjust whitepoint?

            Do we all agree that TCON issues affect also external monitor? - As I am always switch back to windows, because macbook with external monitor still creates very big eye tension. It may be lower than laptop panel, but it is unsustainable. Only windows with Intel UHD 620 GPU is tolerable and allow work unlimited amount of time. I really think panel has nothing to do with most issues people are experiencing, even PWM is like not a big deal for some anymore in comparison to current macbook situation.

              Donux Only windows with Intel UHD 620 GPU is tolerable and allow work unlimited amount of time. I really think panel has nothing to do with most issues people are experiencing,

              Does this mean that you think the internal LCD display on laptops with UHD 620 graphics is comfortable? I'm thinking of trying a ThinkPad T480 (FHD) which has UHD 620 (I care way more about internal display comfort than monitors as I like not being tethered to one desk)

                  DisplaysShouldNotBeTVs I had a ThinkPad T480 a few years ago. This was before my eye strain started, but I remember the screen looked comfortable. I thought 14 inches at 1080p was a weird resolution, between being too fine for 1x resolution but too coarse for 2x high-DPI, but on Windows at least there is decent fractional scaling support.

                  My main complaint with that machine was actually with the keyboard. While it felt amazing, the rollover (number of keys you could press simultaneously) was quite low, so it would beep at me if I typed too fast. I don’t know whether this was ever resolved by a firmware update, if even possible.

                      macsforme I thought 14 inches at 1080p was a weird resolution, between being too fine for 1x resolution but too coarse for 2x high-DPI

                      Lol, the only other option is WQHD which is still too big at 2x and unusable at 1x, and I strongly dislike HiDPI screens anyway, so I think FHD will be fine for me. I've seen other laptops with FHD at 1x and although small it seems alright

                      There's also a 768p TN option but even non-sensitive users complain about eye strain from that config so it doesn't seem like it's worth trying. In the few times I've actually found "strain-free devices with IPS" I vastly prefer those IPS panels over TN anyway

                      The absolute perfect laptop resolution IMO is 1600x900 at 13", but the only time I've even seen that on an IPS and not TN panel, even after researching online, is on my Lenovo Yoga 13 1st Gen. (which has an extremely comfy display, aside from the glossy coating, but ancient enough where I feel like I'm going to break it if I take it anywhere outdoors)

                      1600x900 + matte + IPS is my absolute "dream panel config" but this seems to literally not exist everywhere I've looked

                      macsforme My main complaint with that machine was actually with the keyboard (rollover)

                      Thanks for letting me know. I've heard there is a significant keyboard lottery with the T480, including differences between backlit and non-backlit models as well… I'm curious if this is only a problem with certain manufacturers or a bug in the firmware itself

                          DisplaysShouldNotBeTVs Well, I mean linux experience with intel GPU is always not good, and I can not use it for long. It was different with Radeon elitebook, as I have managed to achieve almost zero strain with external monitor on linux X11. Unfortunately I gave away this laptop now to a family member as they needed it. When it comes to windows lenovo is ok, but after longer session I get a bit ungrounded, not sure if this is overwork, shiny screen or something else. When it comes to the purely eye strain - it does not leave residual eye strain after close the lid. Maybe there is slight feeling in the eyes due to shiny screen, but comparing to macbook air m2, it is nothing. So if you want to get new machine, definitely X1 is the one to go. Probably I would suggest carbon X1 as I had one with same WQHD resolution, only matte screen and it was good. It just build quality is a bit of mixed bag with lenovo, my one was crappy, body started to flake off, and battery died, so I had to return it. Regarding FHD, I did not test it, but I know someone in the office who does full time development on ubuntu was happy about it (it was P range, not X1). I specifically asked and there was no problem. And it was slightly higher than FHD, but not (W)QHD.

                          Update:

                          T-range to my understanding is the same as X1, but X1 is marketed as premium due to its carbon body. I doubt there are any other major differences. T480 sounds like something from older days, which is positive. T14, T14s which are usually compared with X1 are mixed bag - seen good and bad reviews. Personally I would research P range too. It is more expensive, but this is as I understand lenovo "bread and butter" workstations. Maybe even NASA ISS using those too.

                              photon78s I thought about it some time ago, but in reality I think first step is needed to establish percentage of people who experience eye strain. This way at least we could be a bit more self aware how big the problem is from more objective standpoint. Once this data is known, we could evaluate, what is the bottom line (or objective wise) importance for brand such as apple. The reason this step is important - we know and apple knows they cut corners constantly for reasons that could be explained by their various functional goals. E.g. getting rid of ports - which has benefits of efficiency, price, design simplicity, but on another hand caused inconvenience for some users (not all). So its really of trying to find a case where their "cutting corners" approach could have caused more harm than they have initially planned (or not planned at all). Then this could potentially give rise to opening up some of its technologies for communities such as ledstrain to experiment on, or reverse some of the decisions they have made. (We agree that GPU definitely has issues I assume, in addition to other issues of display technology from suppliers).

                                Donux When it comes to windows lenovo is ok

                                Yep, for my use case I would be buying one for Windows and not Linux, so that's all I would be looking for. I'm also definitely going for a matte screen and not shiny

                                Donux Maybe there is slight feeling in the eyes due to shiny screen, but comparing to macbook air m2, it is nothing.

                                This is really good to hear. It's very telling that I would say the majority people find their way to this forum because of an experience with specifically an Apple device (including me)

                                I know that the newest / post-2020 ThinkPads have Iris XE graphics. I'm wondering is Iris XE "as bad for eyestrain as it's made out to be here" on a matte screen laptop? Specifically the internal display

                                As that is my impression right now from what I've read so far, that's why I'm most likely going to pick up a ThinkPad with HD 620 or earlier. But I'm curious if anyone here at all has had a good experience with an Iris XE powered ThinkPad + ditherig.exe

                                    Hi folks!
                                    Try to use the StillColor + the Sub-zero dimming feature at the Lunar App (more about it here https://lunar.fyi/changelog#6_1_1 and here https://forums.macrumors.com/threads/macbook-pro-14-m2pro-pwm-solution.2386836/)

                                    + Via the Lunar you can reduce white point without changing the screen brightness (Lunar app > colors > whites 60% - my option and screen brightness > 80%)

                                    These 2 tools saved my eyes and I can use the new MacBooks without eyestrain again (Air m1 & MPB m1 pro 16")

                                    Best regards

                                      macsforme I found a sealed refurbished base model M2 MacBook Pro 13” on eBay for $750, and it arrived yesterday.

                                      I wanted to follow up on my experience with this model over time as some others have.

                                      I ran several versions of Ventura with roughly equal comfort (or lack thereof). The settings I found most comfortable were: StillColor active, display resolution at native 2X retina, True Tone disabled, and Night Shift disabled. I'm not sure if it made a difference in my case, but I also disabled the touch bar unless the function key was pressed, per the instructions here.

                                      macsforme So far, the display looks stable and mostly comfortable, although there is a slight warm undertone (compared to the older displays I am used to) which I associate with discomfort but I believe this is residual and I can adapt to the screen.

                                      As I previously noted, the panel has uniform colors with a slightly warm undertone (after some time, I would now describe it as a sort of "murky orange" undertone). In my experience, this is consistent with the appearance of modern (especially wide-gamut) displays which I tend to find uncomfortable. I also briefly tried Asahi Linux, and I sensed the same warm undertone (along with perhaps some additional flickering, likely due to the re-introduction of temporal dithering), so I attributed the tone to the panel itself rather than some macOS issue.

                                      While I can tolerate the screen, especially for short periods, I found it to be harsh. I tend to notice the harshness of screens most acutely when I am short on sleep and/or have had more screen time than usual. During one such recent episode, I had some pronounced discomfort while using the device, along with some pain in my forehead right above my eyes. Looking back to one of my other daily-use screens provided immediate relief.

                                      Interestingly, while I alluded to the warm undertone, I would not say that the overall color tone of the display was specifically warm. Visually comparing color palettes between this and an older MacBook side-by-side, I would say the colors themselves (including white) appeared roughly equal if not even slightly cooler on this M2 touchbar MacBook Pro. So, I'm not even sure what I am seeing/sensing. It reminded me somewhat of the murky warm undertone of my 14" M1 Pro MacBook Pro (with mini-LED XDR display) where all my problems started. I speculated earlier that I may still have some residual psychological effects/associations which could be overcome with regular use. I still allow for this possibility, but unfortunately I do not have the ability to make this my primary device and use it for hours every day to find out.

                                      As a final point of comparison, I recently received a work-issued 16" M1 Max MacBook Pro (with mini-LED XDR display), and forced to use it as a daily driver for about two weeks of training. In theory, this machine should have bothered me severely, but I actually found it quite tolerable and found the display to be clear, with a pleasant cool undertone (after disabling True Tone) such as I am accustomed to. This was even before enabling StillColor (I could not upgrade past Monterey until after the training). I compared this machine side-by-side with my M2 touchbar MacBook Pro, and counterintuitively I actually found the 16" XDR panel more pleasant and tolerable. I know a few others here have reported comparing 14" and 16" MacBook Pro XDR panels side-by-side and finding some much more tolerable than others, so this must be the panel lottery in effect.

                                      Ultimately, I do not plan to keep the M2 touchbar MacBook Pro, as I consider simply tolerating a device for short periods to be unacceptable. After years of struggling to find a modern Apple product that does not bother me, I am weary of the fight and I sense that I may be coming to the end of my time as their customer. My last option may be a desktop Mini or Studio, but with forced 10-bit color output from any Apple Silicon Mac to my standard monitors (likely triggering FRC), I am deeply skeptical.

                                            macsforme which panel of the MacBook 2022 model? Mine is the ones with a lot of zeros.

                                            I have mine for two weeks now and with patching on and off I think I am getting more comfortable using the screen (without a patch).

                                            For me it seems like the screen is more comfortable under 60% brightness

                                                karut It was a DCN panel with PROD+B000000000000+00000000000000000000000000. From what I've read here, I believe my panel was a good one (especially as far as uniformity) compared to some other descriptions, so I suspect the underlying technology is what is bothering me.

                                                I concur that certain brightness levels were more comfortable than others. For me, it seemed to be a very specific tick around or just over 50% that was best.

                                                I'm glad that patching seems to be working for you. I would concede that I might also be able to adjust to it given the right circumstances and enough time.

                                                  karut Changing the "white point" via the Lunar App you can reduce the brightness of your screen without changing real brightness (100%), which will not change the voltage of the screen brightness and PWM. It will be much easier for your eyes
