twomee give your eyes some rest, at least 12 hours without looking at LEDs. The muscles are strained and need to recover. Does your external screen have PWM? I'm not a professional- I literally did not know what temporal dithering was a month ago.
jordan unfortunately I don't use Windows nor is it or driver programming my forte, but I'm sure there are enterprising individuals out there that can help. It shouldn't be hard as long as it's possible.
Sunspark are you asking whether changing the color profile on macOS turns off dithering? Nothing turns off dithering (in my experience so far) except setting enableDither to false on the driver. I do find more comfort with an sRGB profile rather than P3, but I need to do more testing. What is IT Content? I believe banding is dependent on a few things, and correct me if I'm wrong, but display quality, color profile, color depth and dithering are all simultaneous factors.
sakraycore an iOS app should be possible, although there will additional hurdles with distribution and testing. The IOKit entitlements will prevent such an app from getting into the App Store, probably would need to jailbreak your iPhone to sideload the app, or move to Europe.
jordan it's a night and day difference. I will never vouch for the M3 Max MBP built-in display because it does exhibit PWM, but using a flicker-free external monitor is fine now. Adjusting blue light and color profile are additional measures that I also take.
photon78s Do you have any recommendations such tools? Could help testing whether different types of cables affect the image.
async have you seen the new Elgato 4K X capture card it advertises 4K@144Hz passthrough and a built-in EDID editor
Donux does your 13" M2 MBA have PWM?
ryans banding is subtle. For most purpose, it's actually surprising that there is no degradation in image quality. If you have to do serious graphics/video editing and need perfect colors you can turn temporal dithering back on temporarily.
