Very important that you point out that has eye effects. It sounds to me quiet mode, by prioritizing energy saving and less fan noise, modifies the graphics routines as well?

Previously, the performance modes is something I leave on balanced all the time. In quiet mode, I don't like the power button LED turning blue.

So now you prefer the dynamic bios setting over discrete? Unplugging does sets limits for performance and tells the gpu and cpu it will not have enough power to play with. Like setting quiet mode, not sure it has an impact on dithering that I have to look into. Unplugged, you will not have access to performance mode only balanced and quiet?

Do you have the latest BIOS updates? Perhaps, it would be good to check if you can rollback to older BIOS version in case some update causes undesired changes. Their should be a setting in BIOS to enable rollback called "BIOS Flash Back" or something similar for your model.

Similarly, my T480s is comfortable and running on and only has UHD graphics of an older generation (UHD Graphics 620 versus Intel UHD Graphics 770 for your Legion)

    photon78s I don't know what mine is. I'm so scared to try the legion 😅 I am still in a flareup idk why!! I'm going to get a upper cervical adjustment with the atlas orthogonal technique soon and see if it helps. My C1 and c3/4 seem to have alot of instability, doesn't hold long. Eyes are very blurry/slight double vision at the moment.

    So is the Intel UHD graphics better to use on quiet mode then?

        I personally don't feel a difference between quiet mode and balanced running on iGPU or discrete. Looks like Dadab12 prefers iGPU and quiet mode. I have found that ditherig works or at least has an visual effect on the iGPU of my 7i using blooey's banding test chart. Disabling all dithering in ditherig produces noticeable light red and greenish artifacts. Enabling temporal dithering from ditherig produces naked eye visible waves moving across the 7 to 12 bit bands (maybe even 6 bit band hard to see). This effect is visible only in 60hz mode.

        I pray everything goes well with your procedure!

            photon78s it's so frustrating because I won't know what works if I don't try but then if I flare up I'll feel even worse than I do now for weeks to months since it takes awhile to recover. I think that hp omen 27q true 8 bit that I have may be a safer option so that's what I should test soon now that it's after Easter lol. Just gotta decide between my precision 7820 xeon 4216 /rtx 5000, 13600k/Intel arc a770, or 10900kf/rtx 4000. I guess to is decide on what OS to run. I'm leaning towards win7 to start and then 1809 maybe after?

            I did get a rtx 4090 MSI suprim X recently for my crypto mining rig so I'll have that to test
            ...eventually... Lol

            The legion unsure if that's a good option right now.

            I appreciate that brother 🙏🏻
            I can tell when my neck is out of alignment because my vision will be more blurry as well as other symptoms. Good tell sign visually is looking in a mirror and noticing if one shoulder is lower than the other. I guess too if one leg is longer than the other. Do you have neck issues btw?

                It seems we are still discovering new things and quirks with the 7is all the time.

                It just seems to me older OS, drivers, and hardware are a "safer" starting point than the 7i. Obviously it makes sense to me to have recovered as much as possible before doing any risky testing.

                  photon78s Not sure what exact panel, but I know that it's a 6bit panel (which by default, is temporally dithered to 8bit entirely by the GPU, and not by the panel itself, quite uniquely)

                  This means that even this "FRC" can be entirely disabled with ditherig.exe, which will reveal the panel's true 6bit form. Suddenly banding will appear everywhere, even on photo wallpapers, with RGB precision cut in half.

                  Which makes it very clear that it is a 6bit panel and can actually be used in "true 6bit" if dithering is disabled

                  BTW just as a disclaimer I do suspect the display does have some level of PWM — but for whatever reason it does not seem to hurt text readability, focus, or productivity for me at all despite me usually having problems with pretty much all other PWM on TVs, phones, monitors, and lightbulbs.

                  It was already generally good for the 11 years I've owned it, and it's only became even better after finally realizing I could disable dithering — since now, not even long lines of text shimmer at all!

                  May not the best choice for someone like jordan though with a lot more serious symptoms from PWM.

                  But for me, it checks all the boxes for being able to see a ton on the screen at once, think productively, stay focused, not get tired, use the computer fast without getting motion sick at all — it just totally works for me for some reason.

                  Maybe it's due to some different style of scanning used for the PWM instead of the whole screen flashing at the same time? Or maybe it just has a much more comfortable backlight spectrum? No idea, but it's dither-free — and if it works, it works.

                      My man, I have Ehlers Danlos, so I know neck instability.

                      I have so many weird eye symptoms. Extreme visual snow, double vision that comes and goes, vision that at times is much worse than others.

                      It's a terrible predicament to be in.. I also have more health problems and I can barely think clearly at this point. I have dementia like symptoms.

                      Anyways, I hope you get your spine better. I think i'm a lost cause lol. And i'm in so much agony trying to figure out what I should do with this laptop, return it or not. It also underperforms below average and the battery life even on the intergrated graphics and 60hz is sub par. And the Wi-Fi sucks. I do wonder if I should try to exchange it for another legion, perhaps it's a laptop/panel lottery.

                      Also, can I fresh install windows without being fucked by the return policy/warranty?

                      What other laptops are available that are strong enough? I don't want to be relegated to an old laptop.

                        photon78s

                        I still have a week to return my laptop.

                        Does 'Ditherig' void the warranty? it says something about it on the site.

                            Dadab12

                            I don't understand how it should void the warranty. It should not at all affect the warranty. I have ditherig running without problems. Remember, ditherig is for your laptop's iGPU and the colorcontrol program is for your nvidia dGPU.

                              Dadab12

                              To emphasize, it should not at all affect the laptop's warranty. The warranty info on the ditherig site only means that the guy who wrote this software program does not offer warranty for his software.

                              About other "strong enough" laptops, check out this discussion with the Asus Strix laptops:

                              https://ledstrain.org/d/2749-asus-strix-g18-2024

                                  photon78s

                                  Thanks.

                                  i saw that discussion. The issue with the Strix is its size and the fact that it’s obnoxiously ugly to me. lol

                                    Some more curiosities:

                                    Unlike my PCs, both the mac mini and the 13 inch MBP Touch Bar I've tested emit a strong wireless emf signal upon boot up and then the signal stops. I don't know how to disable this. It is not controllable from within Mac OS with the standard wifi or bluetooth settings.

                                    The Ra color rendering index value is higher on the 7i than on the MBP TB (87.7 versus 71.5) as measured with spectrometer. Both have similar spectrums as expected for WLED backlight displays that are a far cry from natural sunlight spectrum.

                                      So I setup two crypto mining PCs both 7950x cpus BUT first PC is a asus x670e crosshair motherboard and second PC is a b650m edge MSI itx motherboard They are meant to be running headless (no screen) BUT when I enter bios and configure CPU settings and also short time booted in HiveOS(Linux mining OS) The x670e Asus makes me feel AWFUL.. the MSI b650m itx one didn't bother me like the asus. I now am a strong believer in motherboards causing issues... Same HDMI cord too and this was using the motherboards HDMI port with Ryzen 7950x iGPU. Feeling not so good right now. I've been tinkering with them the last 3 days mostly msi and just earlier I tweaked the asus more and just is BAD. I felt this a little the last few days when I used it but this time I used it longer and yikes not good..

                                      It's basically the same feeling I got with the iPhone 11

                                      Edit: this was connected to my old Samsung TV that I normally don't use

                                        jordan

                                        So frustrating to add now motherboards as eyestrain contributor. You would think that boards supporting the same chip should be more consistent. At least you don't have to config those rigs often. Set it and forget it. Next time maybe you could run the iGPU output through a hdmi converter and OBS to get rid of the dithering on whatever computer you find most comfortable.

                                        Don't laugh, I'm being serious unless you have food allergy.

                                        I need to find a good recipe.

                                        Here is the spectrum for the 7i
                                        https://ibb.co/7z6CvRv

                                        and the "good" M2 MBP Touch Bar:
                                        https://ibb.co/TKWmjyQ

                                        Both are spikey but the red seems unbalanced on the Mac. Night light off and default settings on 7i. Mac is running sRGB color profile with true tone and night light off. Sunlight is a gentle curve with no big spikes.
