So I agree that displays should not be televisions. My mistake was trying two Eizo monitors designed to help people make and color grade television shows and movies. Doh!

Subpixel layout is another factor to consider for eyestrain particularly with text. Again, their is a lack of consistency or lack of data at all on this matter.

Read the review titled "Subpixel layout is BGR instead RGB!"

I have bought this monitor from Amazon.de (because I live in EU) with high hopes because I work in 3d Multimedia industry (3d rendering, color critical work etc.) but after 1 month of use I have noticed a strange phenomenon: the monitor started to develop some kind of convergence issue. From my knowledge I know there’s no such thing as old-school convergence on a high-end IPS monitor but after a closer look, looks like this “high-end” monitor have this problem. (See photo attached)

LCD pixels are actually made up of three sub-pixels. From left to right, those sub-pixels are red, green, blue, but in the case of this piece of junk the effect is so visible that nearly kills your eyes after you read and work with documents and even images.

After some serious digging, I have found out that this monitor has BGR subpixel layout. This affects very negatively to text clarity and there are no complete fixes for this “issue” yet…

Or one can flip the monitor so it is used inverted.

    photon78s One way or another, you can select the correct subpixel layout in modern operating system's font settings. If you use Windows, I guess it's still being done via ClearType Text Tuner.
    This is only (not particularly) a font issue and only an issue if the fonts by default are both antialiased and the antialiasing is using subpixel rendering, AND for whatever reason the operating system ignored or failed to detect the monitor's subpixel layout in its EDID information.

    Granted a badly programmed application could ignore all those settings on purpose, but that's not the monitor's fault.

    That can actually introduce eye strain, depending on how the graphics driver handles the flipping.

          Wording corrected based on your feedback. Yes, in Windows, ClearType is used to adjust font appearance and their are some github projects to help with this as well for Windows. My issue is with the lack of official documentation on this subpixel layout (unless product is reviewed on sites like rtings.com).

            photon78s It is for windows 11 home only.

            I ran win10 22h2 home single language instead of last win11, and BIOS key activated successfully. Originally w11 home single-language was pre installed on laptop

                I am testing thinkbook ultra 7 iGPU based now with w10 22h2 19045.4046 and there is pain in the temples, but very, very smoooooth at first time, not so strong compared to w10 21h2 and w10 2004 did. And still no paperlook ( which reference w10 1809 did )

                  ordered the new lenovo legion 7 pro. really hope it doesn’t fuck my eyes.

                  edit: it’s the 2024 model and i read that it supports 100% dci-p3? if that’s true does that mean the screen is different and may prove to be worse for the eyes?

                    Dadab12

                    Not sure. They can reuse the same panel and dci-p3 support is not anything special but as others have reported it might mean a more straining display.

                        photon78s

                        others have reported it is a more straining display?

                        should i cancel my order and look for the previous model or just test it out?

                            Dadab12 well the rx8h one I THINK is the one photon has. I'm not sure wether one might be worse than the other.

                              I have model: 16IRX8H

                              It's your call and you also have panel lottery even if you get the exact same model version.
                              What works for me may not work for you. Here is what I do:

                              Edit: Use it only at 240hz refresh rate on the laptop display. Don't set it to 60hz (some might prefer the opposite)
                              Use it around 3 feet or about 1 meter away from the laptop display. For me less light in my peripheral vision is better.
                              The 7i is on a laptop stand with the screen top set up around eye level (basic ergonomics)
                              My environment is lit as much as possible with natural light not other LED lighting.
                              I use non-flickering reading lamps as monitor bias lighting in the evening.
                              Use an external keyboard
                              Turn off and never use the laptop keyboard backlight as it has strong flicker
                              A blue blocking colored gel filter is used to make the screen look less harsh
                              I'm still testing the iris blue light filter app (https://iristech.co/)
                              I try to do the 20-20-20 routine: https://www.healthline.com/health/eye-health/20-20-20-rule
                              I am working on liver and kidney health as their is connection between eyes and the rest of the body

                                  Appreciate it.

                                  i actually don’t know what to do. the store i bought it from no longer has the older models and the price similar anyways.

                                  one of the reasons i wanted to buy a pro 7 was because of your positive experience in regards to eye sight health. can’t say i’m not concerned. so it’s either i roll with it and hope for the best or cancel my order and look for the older model across different stores for roughly the same price or a tad cheaper. hilarious.

                                  why do you suggest an external keyboard? for what purpose? i’d like to use this laptop across different rooms and even take it out with me sometimes lol

                                      I forgot to mention I have more eyestrain when running my 7i at 60hz so I leave it at 240hz. Mine defaults to 240hz out of the box. It should be the same with your newer version. If you could give me the full specs of your purchase, maybe I can confirm some things.

                                      Edit: also I installed the version 532.10 nvidia studio driver for the rtx gpu not the game ready driver. No particular reason I installed version 532.10 as I'm still exploring older driver versions for potential solutions to reduce eyestrain.

                                      If the 7i (whichever model) does not work out, in this discussion I have also tested my T480s (bought ebay used for around $200-$300). I run linux mint 21.3 with it now and tested windows 1809 enterprise LTSC on it as well and both feel relatively comfortable. I swapped the LG screen panel it came with for the AUO panel because of my microscope testing. The AUO panel seemed to have less pixel flicker. The T480s I have does not have discrete gpu so no gaming. Their is another version of the T480s with nvidia mx150 discrete gpu. I don't know if the mx150 has temporal dithering issues. In any version, it's a work laptop.

                                      The forum member DisplaysShouldNotBeTVs mentioned the 2012 Lenovo IdeaPad Yoga with Win8.1 as safe here:

                                      I use an external thinkpad keyboard first because the laptop is placed on a stand away from me and to raise the monitor to eye level forcing me not to have too bad posture. Second reason is less potential "EMF" (basically electrical interference with your body, sounds weird right?) but that is a tricky and controversial topic even more so than LED flickering.

                                          photon78s

                                          I see. Well, I will get a keyboard and a good laptop stand.

                                          What about a good monitor? I'd like a quality monitor with minimal eye strain. Have you had any experience with the Gigabyte M28u/M32u? Can't zero in on a monitor right now.

                                              Dadab12

                                              I'm also still looking for a true 8 bit monitor with no FRC. Haven't tried those gigabyte models. I have the LG monitor (see table) but it is listed as 8 bit + FRC.
