XDR „Superbrightness“ 1600nits

Feature Requests
1

Hi,

are there any plans to support Apple XDR Displays (and MB Pro M1 and above) better to support the brightness more than 500 nits (=100%)?

The „super brightness“ function at the moment only uses filters if I am correct. But there are better possibilities.

Apps like lunar.fyi, Vivid or BetterDisplay support these, for example. A free and open source POC is here - there are also named alternative apps: GitHub - starkdmi/BrightXDR: Free and Open Source alternative to Vivid macOS application to extend Apple XDR display brightness from 500 up to 1600 nits.

Would be great to see such a feature in BTT too! :slight_smile:

Cheers!

Looking at the code of BrightXDR, this is pretty much the same as BTT does. (Overlaying the screen with a HDR enabled view, which in return enables the HDR / 1600nits mode on the display)

BetterDisplay makes use of lower level functions in private frameworks as far as I know, but I currently don't want to get into this (also due to the risks involved in calling private functions in a scenario that can potentially harm the hardware)

(I use BetterDisplay myself and it's absolutely worth the money, they know what they are doing)

Ah but it seems like the required values have changed with a recent macOS version. To achieve a similar result to BetterDisplay, these values seem to work good nowadays:
