Disable temporal dithering / lower bit depth #1201

Unfortunately you can't really change the bit-depth on M1 systems afaik if lower bit-depth mode options are not available in the set-resolution list. The bit-depth options depend on what the display reports about itself and how the display connection is negotiated. There are some ways to change color encoding and bit depth by editing the windowserver configuration files though. Normally M1 macOS will opt for "billions of colors" (10-bit color depth) if it can which might create dithering at the display end. Dummies use "millions of colors" (8-bit depth) so if these get mirrored it might help with this. But to be honest I'd need to dive into the entire issue a bit more. Somewhat related + a link to a discussion about how settings could be edited that might affect this as well: #741 |

Hi there, Bumped into this discussion thread, and I have a similar issue. I am fine with the built-in monitor, but I am guessing the notorious flickering issue on the external monitors connected to M1/M2 Macs is also related to this issue. I noticed you recently updated BetterDisplay to make it possible to override EDID for M1/M2 Macs. I am not familiar with EDID, so may I ask whether it's possible to force my M1 MacBook to output 8-bit color depth to my external monitor to avoid temporal dithering? I saw another discussion #1473, where people were talking about if you could make a simple toggle to force RGB, it would be an instant buy for many users. I think it will be the same for temporal dithering (a simple option to change the color depth). At least for me, it will be an instant buy. That being said, if editing EDID could enforce it, I would also buy it. Just want to make sure it works before I make the purchase. Thanks! |

There is currently a petition on change.org related to this subject. People want to have simple toggles in the menu to disable PWM, dithering, and other similar settings. If you could add these toggles to BD, it would definitely be an "instant buy", as mentioned previously. |

Checkout stillcolor <https://github.com/aiaf/Stillcolor> project on
github. It finally seems to disable temporal dithering on M1 macs. I see

However, the headaches from macos are still here even with external monitor(

Hi, is there a way in the app to disable temporal dithering (MBA M1 2020), or lower bit depth (I got recommendation on ledstrain.com, since I have eye strain issues) except mirroring. I notieced if I mirror the screen I don't feel eye strain, but the resolution on my 4K monitor is then cut. So, is there a way to block this without mirroring method, thanks! Will buy the app of course if this is possible!
