TV update for me……I sold my hisense 7120 as it still wasn't 100% comfortable and thought I'd give the LG oleds a go. My eyes don't agree with 120hz and LG had just released the A1 which was a 60hz panel. My worry was that the contrast is infinite but thought I can boost the gamma and lower the contrast if needed. After many hours/days of adjusting I have settled on the following setting and I will now see how it goes over the next few days.

I changed gamma to 1.9, used film maker mode which turns off most artificial settings and turned off all motion settings like soe etc. The colour temp defaults at cold 20 and after going backwards and forwards with warm settings I just feel that cool 20 agrees with me so kept it. Sharpness down to zero as artificial sharpening causes strain. After viewing this set up for days there was something still not right. When I viewed pictures with small items such as a crowd or football players it felt fuzzy and felt it "pulled" at my eyeballs and I would start to feel pain at sides of my eyes. I then continued to play with the settings much to my wife's annoyence. I then went into the fine tune option and turned down the luminance on every colour (red, blue, green, cyan, magenta and yellow)to as low as I could (happened to be -30).

I now find the image is much clearer, smaller items aren't fuzzy anymore and the image feels "flatter" which may sound boring but I find it comfortable so far. It's early days and will give it a few days and report back.

If anyone as the LG A1 oled then I can list my detailed settings if anyone wants to try it.

I also still use my Honor 20 mobile phone and find it amazingly comfortable as it PWM free and contrast ratio of less than 1000:1

Hope helps anyone.

    Yeah …had this mobile for about 2 years now with no issues. I've had problems with many mobiles and find that as long as the contrast ratio is under 1000:1 and no pwm then I'm good. I use notebookcheck website for every phone review as they measure pwm and contrast ratio.

      Sounds like a binocular vision deficiency. Pain in the side of your head around the temples is your brain trying to physically move your eyeball forward or backward to change where it is focusing. The "Pulling" you feel are the muscles attached to your eye (The superior, medial, and lateral rectus muscles) doing the same.

      Your brain is falsely intepreting your vision as unbalanced, and so is trying to compensate by moving your eye back and forth to regain balance, just like a camera lens on a digital camera moves in and out when trying to focus.

        This site doesn't work for me any more. Too much animation.

        I've tried a number of computer monitors and conventional tablet screens. At best, I have to set the brightness and contrast to the minimum. I often have to tweak other settings to get far enough below the minimum. I often get visual distortions anyway, as well as reflections from any other light. At worst, I can try that, but it still gives me a migraine.

        I've also tried e-ink devices with much better luck. It may take some tweaking, and choosing e-ink friendly apps, but it can be much better for reading. But I can't find a way to stop the blinking cursors in Android, so it isn't much good for me for note-taking, editing, or writing.

        I've also tried using my tablet for screen mirroring, but it's too small to be very helpful. There are larger 13.3" and 25.3" devices, but they are much much more expensive.

          Ananiujitha At best, I have to set the brightness and contrast to the minimum.

          That may be spectrum-related. I suffer from the same problem, plus I can't use any LED bulbs. What helped me is a quantum dot TV. My AMOLED smartphone is similarly usable. I'm just talking about the brightness issue here, not about flicker or temporal dithering, which IMO are separate issues. If you want to be able to look at a display at regular brightness, you may need to look for RGB spectrum which is characteristic for AMOLED and quantum dot displays (which have a violet backlight; note that unfortunately some quantum dot manufacturers use a White LED).

          Stay away from White LED and the brightness problem in particular may be solved.

              Do you use any app or configuration to reduce the strain ? I bought a refurbished Nova 5t that is supposed to be almost the same as Honor 20 but sadly it gives me a slight eyestrain after a few minutes.

                Gurm Finally found another person with a Dell XPS 13 9350 2015 laptop.
                The display is INSANELY comfortable right?! I just use windows night-light at around 45% to reduce the blue light, and that is one of the BEST MOST COMFORTABLE looking displays I've ever seen.
                It looks so flat, non-imposing, and is so gentle on the eyes.

                How would you compare the Dell XPS 13 9350 display to the CCFL Dell monitors that you have?
                Are the CCFL monitors equally and as comfortable as the DELL?

                  I have two workstation in different locations and on two I had problems such as you describe. And on both of them the problem was solved by changing the BIOS version of the motherboard.
                  I have a theory that this is due to poor compatibility of devices from different generations. For example, you have a 2018 motherboard and you put a 2022 video card into it. I think there must be desynchronization issues here.
                  In my case, it was too fresh a bios that was not compatible with old cards, so I had to roll back. It's on the first workstation.
                  The second one had to update the bios to the latest version. And after that my new 3070 worked fine. No eye pain, no graininess in pictures, no bad color reproduction.
                  UPD: Sorry forgot to mention that this was an answer in this thread https://ledstrain.org/d/1688-rtx-a4000-causes-eyestrain-with-true-10-bit-monitor/32, I just copy/paste.

                    CepheiHR8938 Not sure how much I can help, but for research purposes could you list the motherboards, BIOS versions and GPUs in use?

                        JTL I'm sorry, maybe I expressed myself incorrectly. I just shared this solution to the problem in the hope that it will help someone.
                        On one station i have the following configuration:

                        • motherboard: MSI B450 Tomahawk
                        • cards: Gigabyte GT 730/Palit GTX 1060 (both of them had problem with new bios)
                          Originally, it was installed first bios version and I had no problem with this configuration. But I decided to update bios to speed up my RAM (there is problem with old bios version) and after that I faced with eye pain. I began to look for a problem and tried a lot of things. In the end, nothing but returning to the old BIOS did not help. I tried all versions of the BIOS but only the very first one worked correctly.

                        Second one station:

                        • motherboard: Gigabyte Z370 HD3P

                        • Palit 3070 gaming pro/Palit GTX 1060
                          I bought a new video card (3070) and inserted it instead of the old one (1060). Immediately felt a deterioration in the screen image and eye pain. Manipulations with drivers did not help. After I got the experience of manipulating the BIOS in the previous workstation I decided to play around with this here. And surprise, the latest version of the motherboard BIOS solved the problem.

                          One more recommendation, It's better to let Windows install its own driver for the current graphics card. After that, you can update the drivers but do not select the clean install option. And of course you need to use Display Driver Uninstaller. If Windows does not want to install its own drivers, try run some application that requires hardware acceleration for example a browser.

                          What I use:

                          • Windows 10 Home, Ubuntu 22.04, Manjaro 21.3, latest updates.
                          • Asus Prime H410M-A, the latest bios.
                          • Intel i5-10400F (without integrated GPU)
                          • PNY Nvidia Quadro T600 with mini displayport to VGA adapter and mini displayport to hdmi adapter.
                          • Two monitors: very old AG Neovo F-417 on VGA and ViewSonic VP2458 on hdmi. No problems with F-417 at all. ViewSonic has adjusted settings to make it bearable: brightness 0, contrast 45, color range Full (the same setting in Nvidia settings), color temp Warm and low gamma 1.8, no blue light reduction (it's a marketing trick).
                          • Latest Nvidia drivers 517.40. Without Nvidia Experience. Linux also uses Nvidia proprietary drivers.
                          • Mini display port to VGA adapter StarTech MDP2VGA2.
                          • Mini display port to HDMI adapter Assmann GmbH.

                          Eye problems are less pronounced on Windows than on Ubuntu. On Ubuntu I usually switch to VGA for both monitors or work just with F-417. For some reason, Ubuntu causes no problems with this monitor and this setup. Manjaro is the most comfortable with ViewSonic on hdmi connection.

                          Desktop setup isn't a problem for me as of now. I sit around 6 feet away from a 32" lg monitor.

                          I still haven't found a phone that I can use without problems. Dithering for me seems to cause bad headaches as well as pwm.

                          I can use Amazon Fire HD 10 Plus for hours without any problems. I wish there was an android or iphone with the same screen/dithering.

                          I am here with the focusing issue; seeing glows around high contrasted elements and feeling as colors were turning metallic. At least on bad hw/sw.

                          For me mainly all the displays are bad that's produced after ~2017 when it comes to gaming monitors (tried only those), thus I'm forced to stick with some old dumb displays. Other PC HW stuff doesn't matter, nor SW-wise i.e. the kind of Windows builds, Linux, driver, etc.

                          As for games, there are AAA titles, where this strange kind of rendering is used and visuals are feeling like the above mentioned, again since the magic date of ~2017…

                          Interestingly then, business monitors/notebooks at my work are just working without any problem, no matter again the SW side, like OS, driver, whatnot.

                          As I mentioned in another thread before, the iphone 13 pro max is working for me flawlessly after turning down the white point in the accessibility options. Tried the same method for games with Reshade, so the final result in the rendering chain gets the white point reduction, but no luck.

                          Long story short (for my case at least); something happened around 2017 and noone knows/tells what.

                          This kind (or part?) of "technology" seems not to be present in business, only in entertainment & co. And it is well… hidden away(?)

                            tsb If what you say is true (not doubting you, just a for instance) the only way I can see making progress is if we have two setups, one of which is "useable" and does not have this changed rendering and one that does, and they are otherwise displaying identical content. Somewhat easier to find the "needle in the haystack".

                            • tsb replied to this.

                                JTL Yep thats the problem, i cannot find two identical “systems” having one with the thing ON, while OFF on the other. Like having an SW at two different build level, where the before-after effect could be witnessed. Or a display with old and new Firmware on it, etc. Its even harder, since I dont have problems with different Gpu Bioses, different Win/Linux builds etc.

                                  I can still use any Windows 7 build just fine, all my home PC's are set up with Windows 7
                                  For wok I have to use Windows 10 but patching allows me to tolerate it.
