Donux what specs is your machine that runs Ubuntu without symptoms?

      jordan I run lenovo carbon X1 yoga 4th gen with intel hd 620. But this is strickly on X11. Wayland is doing something which caused eye strain on HP elitebook 845 G8 and this one. Maybe X11 due to its legacy layers, ads a bit of buffer at the expense of rendering. I do not know, but it is very good on external monitor. The native screen I am also happy on linux, apart from glossy screen irritation. I suggest checking out Carbon X1 any model with WQHD or FHD matte screen. But I personally of course prefer Mac OS X and will always be coming back to it, as it is superior system to any other system out there.

          Do you know the exact panel model of your X1? I've been doing screen swaps on 8th gen T480 series. Now using a glossy WQHD screen in regular T480 non s model.

              HWiNFO might show it. AUO B140QAN02.3 is the panel I was using in T480s and it worked for me as well.

                      I have some updates on the app:

                      1. App does not keep non default setting in color mode. If you select 8 bit, after sleeping/standby it will reset back to 10bit, so would need each to to set it back. Not a big issue.
                      2. And this is not really within scope, but virtual display does not show correct aspect ration on MBA M2, i.e. shows two blocks at top and bottom, regardless if you select 16:9 or 16:10. However, I have only tested this once and not really using it while testing.

                      Also, I have tried to work on my MBA M2 with external monitor for two days in the row with 8 bit setup, and with all disabled monitor sensors (just in case this could be somehow related to eye strain), and once my eye adjusted, there was no problem. But of course to some level it comes down to what standard you set and with what do you compare. If going from linux -> macbook causes eye strain, but going from macbook -> linux does not (all scenarios using same external monitor), perhaps there is some level of subjective adaptivity, but objectively speaking one is clearly better for eyes.

                      Do you have the touchscreen panel? A similar product from this seller.

                      Also possibly B140QAN02.2 One can potentially use these types of panel to diy your own portable monitor for use with Macs in headless and normal configurations.

                          photon78s These panels look like a match, and DYI would of course be amazing. But how do you do that? I thought macs are really draconian when it comes to blocking any non original parts? Or you have some HDMI controller in mind ?

                          btw, yes my one is touchscreen glossy.

                              Possibly diy portable monitor. I can confirm this driver board (0.5 mm pitch with cable version) is plug and play with my B140QAN02.0 panel from T480. However, I'm not sure it can be made to work with touchscreen panels. I got the version 8.3 of the board despite the picture showing v8.0. The hard part is finding or making an enclosure for it. It works with usb-c to displayport cable. More testing is needed to see if the board itself introduces more eyestrain.

                                I have a macbook pro m3. It came with sonoma 14.5, and I had some slight irritation while looking at the screen. After downloading stillcolor, it was just fine to use for hours. I recently updated to 14.6 and the pain was back, even with stillcolor. Today I put my macbook into low power mode always on, and this has relieved some pain.

                                  is there any way to disable dithering for android ?

                                  DisplaysShouldNotBeTVs used this for a month now. Almost fixed my 15 pro max. Tried turning it off yesterday and had pretty significant eye strain thru the day. Not just when looking at the phone. Also had this shitty effect where reds on other monitors seem really bright.

                                    I remember few month ago, you guys were discussing TCON here, just found info on apple website for their Apple Pro XDR Display.

                                    It looks like it's made by apple.

                                      madmozg Interesting, I have not noticed this. But what does it mean? All those Airs, Pros macbooks are designed by apple too? Or is it a new messaging that could potentially mean, all products that have this mentioned, have some change in TCON?

                                          Donux If remember correctly @aiaf was doing some research for TCON from another manufacturer, so I just wanted to share that looks like apple have their own tcon chip.

                                            madmozg oh wait I just realized, if they mentioned TCON chip, does it mean that Apple Pro XDR display is not a true 10bit display, but controlled by FRC and mini-LED?

                                                I do not know what it means, bet I have very noticeable eye strain even using macbook with noMachnine remote connection from Windows laptop. Is this expected considering that TCON is flawed? From my side dithering disabled on betterDisplay app.

                                                  waydabber happy to report that this works! This is a major step into solving another piece of the temporal dithering puzzle. Thank you! I no longer need to use an old HDMI wire to force 8bpc on my external monitor.

                                                  Tested on SAMSUNG 32” Odyssey G7 with Display Port. Using @Blooey gradient image, banding is obvious in
                                                  8-bit mode vs 10-bit mode (GPU/DCP dithering disabled in both cases)

                                                  For anyone out of the loop, this means that external displays that are reported to be 10-bit as 8-bit+FRC can now function in native 8-bit mode without temporal dithering. No need for crappy wires!

                                                  Additionally, with GPU/DCP dithering disabled, you can guarantee that the display receives a clean 8-bit signal from your Apple Silicon Mac.

                                                  The only issue as reported here is the display reverting back to 10-bit mode on sleep which is very inconvenient.

                                                      madmozg a TCON has many necessary functions besides FRC. It is widely reported that Pro Display XDR is the only true 10-bit display in Apple's product line.
