CLI option for minimum/maximum XDR nits?

[dkulchenko]

Is there a way to configure the above values via CLI? I'm trying to set up a Hammerspoon automation to limit max brightness to 500 nits on battery (and unlock 1600 nits when plugged in), to limit battery drain. Right now, I have it set up to toggle:

betterdisplaycli set -nativeBrightnessUpscaling=off/on

which works, but is pretty jarring due to the screen flashing. Is there a way to set max nits via CLI instead?

Thank you!

Hi there,

sadly, right now you can't change this value via CLI easily - but all BetterDisplay stored data is (somewhat) accessible using userdefaults. I recommend changing the value to some weird number, run defaults export pro.betterdisplay.BetterDisplay ~/Desktop/settings.plist, search for the weird number with BBEdit in the plist file, look at it's key and then use defaults to directly change the value of the key - this should sync back to the app. However for the change to take effect, you still need to use the off/on as it won't take effect this way right away.

It is a hack but probably works.
