Tweak minimum dimming level with Native XDR Brightness Upscaling

[gsajith]

Hi! I've been using BetterDisplay for about 3 weeks and was very happy with it.

With some recent updates, I'm no longer able to get maximum dimming, nor does it look like I'm able to get peak brightness.

I'm using an M1 Macbook Pro with Brightness Upscaling (Native) enabled and XDR Preset set to Betterdisplay XDR, and yet my minimum brightness (when the brightness adjust UI shows 1 nit) is brighter than when Brightness Upscaling isn't even enabled.

Furthermore, I'm noticing no additional dimming when I adjust the brightness slider from 6% down to 1%.

I'm curious if it's something in my settings, or if something broke for me in a recent update.

Hi there - this is intentional to match the app slider to the control center slider. You can do three things:

• Use software upscaling instead (turn off "Allow native XDR upscaling" under the display's settings)
• Configure the XDR brightness scale ninimum to 0 nits (expand Native XDR settings for that) - this will give the slider (and keyboard) a huge chunk to super-finetune ultra low brightness leveles.
• Allow combined brightness in native XDR mode (expand Native XDR settings for that) - this will allow software dimming as usual below 20% (to tweak this you might want to change the scale minimum to 4 nits however or redefine the dimming point from 20% to 10%).
