henno Sure, I will explain the steps in detail.

Step 1: Download the application from https://www.macupdate.com/app/mac/63642/betterdisplay and install it in your mac

Step 2: Open the application. Create new dummy

Tools -> Create new dummy -> 16:10

Step 3: Mirror the dummy to the main display. Check the checkbox " Set as Main Display" in the dummy screen section.

In the application -> Under the dummy screen ->

Mirror Dummy -> Select color LCD.

Step 4: Increase the LCD brightness to 100%. Set the dummy brightness to 65%. Set the dummy resolution to 1920*1200. Uncheck the "High Resolution HiDPI )".

Step 5: Open display settings and make sure the below color profiles are choosen.

Display settings for dummy: Color profile should be choosen Generic RGB

Display settings for in-built display:

Thats all. Use this settings and see how you are feeling about it. I am feeling much comfortable and relief with this settings. You can play around with brightness of the dummy display & color profiles of Dummy and main display to find the best config for your eyes. Make sure your inbuilt display is always 100% brightness.

      What version of macOS do you have? When I go to System Preferences > Displays, I see

      And whenever any of the non-Apple color profiles are chosen on the main display, the brightness is reduced to quite dark and it is not changeable:

      When I attempt to change the resolution with BetterDisplay, it jumps back to 100% after I change it:

      and this 100% is not particularly bright. I can use it but in a brightly lit room, it becomes hard to see and I must switch back to Apple P3 in order to get some more brightness.

        henno I think you misunderstood few things.

        1. In the display settings - Don't use Built-in Display as Main display. Instead use the Dummy 16:10 as Main display. Built-in Display should mirror the dummy 16:10.

        2. Built-In display brightness should be always 100%.

        3. Adjust the dummy 16:10 display brightness according to your eye comfort. I find 65% brightness in dummy display is usable.

        4. In the betterDisplay application - Set resolution of the dummy to 1920*1200. All other settings in your BetterDisplay should look similar to this below.

        5. Display settings should look like below.

        6. Display settings of the dummy should look like below.



          MacOs version doesn't matter here. But sill for the reference pasting my os version here. Ventura 13.4.1 (c)




          henno if you still couldn't setup, let us connect through Zoom. DM me.

              The m1 pro 16" has an OLED display, which uses PWM. I am confused. I do not see how software might be able to disable PWM flicker?

                caboy m1 and m2 macbook pro use a MINI LED display not OLED. The APP BetterDisplay can't remove the PWM but seems to do something to the dithering. Also, changing the color profile can modify the PWM frequency:

                    Thanks for clarifying.

                    Do you think this would work with a 13" Macbook Pro? From what I understand the 13" does not have PWM. I am not sure about that though.

                      karthi3219 I did manage to set it up after your last instructions. I've been using that setup eversince. However, in bright environments I find it hard to use because the display is too dark.

                          henno you can play around with different settings and find best suits for your eyes. "high resolution high DPI" (radio option in the menu )settings also good for me. This option is for more picture clarity. Also sometimes I increase brightness upto 75-80% still ok for me. Overall this app is savior for me. This is my work laptop. If I this solution isn't exist, I have to resign the job and no other way. As you said , Apple should listen to all victims like us and improve or atleast give some options for us.

                            henno how do find the setup? Is it good except the brightness issue? For me this setup works for 8-9 hours usage with few mins breaks every hour. It's good enough for work. For personal use I have another windows setup. I'm keeping that windows setup intact by disabling all updates and have took enough system image backup and head drive backup to restore in case any update goes through.

                                karthi3219 I can't decide whether this setup is any better than the default macOS setup + sRGB profile. Watching movies on this setup can be problematic due to severe banding in dark scenes. Yet, during daily tasks, I don't notice the banding. After the BetterDisplay trial ends, I'll revert it to the default setup to see if I will miss it and it's worth purchasing.

                                Note: It's still unclear to me why only the color profiles starting with 'Apple' allow for brightness adjustments. Is it the same with you?

                                    I'm using a Macbook Air M2 and Better Display seems to be making a massive difference for me. Been using it for a week or so. Settings are as described by karthi3219 above. If I change the colour profiles from sRGB for the built in display and Generic RGB Profile for the dummy or virtual display, I seem to get eyestrain. Weird. I'd used Better Display on my wife's Intel MBP and it helped a lot there too. Big thanks to you guys for sharing this solution. I hope it helps more people.

                                    The only thing I can't make work is watching Apple TV on the MBA. When the built in display is set to mirror dummy display, video playback on Apple TV is black/ gives no image. But this is a small issue, when the laptop is otherwise great for me currently thanks to this fix. 🙂

                                          I know some of the streaming apps go to black when you try to record/screenshot them. I bet Apple made it that way when watching ATV on a Mac. It probably thinks you're recording or something so it blacks it out.

                                          On your main point that's great that it's working for you… I'm going to try it out on the M3 Air (if one comes out).

                                            Does anyone know of a similar workaround/ fix for Windows on a PC? So, how to enable a dummy display and use it to prevent dithering?

                                            karthi3219 Uncheck the "High Resolution HiDPI )".

                                            Thx for this hack. So basically the window manager uses now a virtual screen and the system does not apply FRC to the output ?
                                            I wonder why you disable hidpi, since this will leave me with an very blurry image (half resolution). How to get the native resolution working ? (mbp 16 m1)

                                                gabigreenhorn Initially I felt enabling hidpi gave me strain. But now, I am feeling comfortable enabling hidpi. we have to basically play with different options in better display, different options in colour profiles and find best working combination. This may change person to person.

                                                I found another solution. This is mostly for folks who have working windows setup (good setup without eyestrain) in personal PC but want to use MacBook for office use. Mostly office laptops are locked to install new softwares and you have to mandatorily upgrade OS frequently. My idea was to use Video capture card plug to Macbook, output the video to Windows PC into a OBS studio and see your macbook screen streamed to Windows PC. This setup is also working for me really good. I have 1 working windows setup with intel i5 config ( 11 year old driver ). I have disabled all windows upgrade on this PC. I stream the Office Macbook screen to this personal pc and able to work on office macbook comfortably. But drawback is, I can use this setup only during work from home. While in office, I use the better display software to use Macbook. For now, with all these tricks, I am managing my software engineering job. Totally all these sucks. My career at risk any time if any of these tricks breaks.

                                                I will shortly post a separate thread with detailed setup of this.

                                                    that is even a crazier hack 😉

                                                    I am working with the betterdisplay solution since some hours now and my eyes feel much better +better focus. The downside is, that the display now feels like max 50% brightness. (this might be tweakable through custom color profile (copy srgb) and increase the luminance to eg 320)

                                                    What is your take on the new macbook air m2 displays and on OLED displays in general ?

                                                      Using the sRGB profile on my MBP 2021 M1 Pro reduced my screen strain by 98%, without needing BetterDisplay. BetterDisplay's virtual mirrored screens didn’t impact my strain at all but they did lower screen quality (color banding). The sRGB profile unfortunately disables brightness adjustments, but the default brightness is generally suitable.

                                                        23 days later

                                                        henno You can create custom display profile based on the Apple's sRGB with your own brightness in the Display settings -> preset -> customize presets (when you click on the preset list). Default sRGB profile has a brightness of 80cd.

                                                          sRGB doesn't do anything to reduce dithering, maybe its just me.
