 - Supports smooth brightness transitions.
 - Seamlessly combined hardware and software dimming extends dimming beyond the minimum brightness available on your display.
 - Synchronize brightness from built-in and Apple screens - replicate Ambient light sensor and touch bar induced changes to a non-Apple external display!
 - Sync up all your displays using a single slider or keyboard shortcuts.
-- Allows dimming to full black (advanced feature).

 - Support for custom keyboard shortcuts as well as standard brightness and media keys on Apple keyboards.
 - Dozens of customization options to tweak the inner workings of the app to suit your hardware and needs (don't forget to enable `Show advanced settings` in app Preferences).
-- Modern, stylish and highly customizable menulet reflecting the design of Control Center introduced in Big Sur.

 ## Supported displays
 
-- Most modern LCD displays from all major manufacturers supported implemented DDC/CI protocol via DisplayPort, HDMI, USB-C or VGA to allow for hardware backlight control.
-- Apple (and LG-Apple) displays and built-in displays are supported using native protocol.
-- LCD and LED Televisions usually do not implement DDC, these are supported using software alternatives to dim the image (some higher-end sets are able to translate this into hardware backlight dimming).
-- OLED or mini/micro-LED displays and televisions are fully supported using gamma table manipulation (this is a no-compromise solution for this class of displays).
-- DisplayLink, Airplay and Sidecar are supported using shade (dark overlay) control.
-- The app is compatible with [BetterDummy](https://github.com/waydabber/BetterDummy) mirrored sets.

 Notable exceptions for hardware control compatibility:
 
+- DDC control using the built-in HDMI port of the 2018 Intel Mac mini, the built-in HDMI port of all M1 Macs (MacBook Pro 14" and 16", Mac Mini, Mac Studio) and the built-in HDMI port of the entry level M2 Mac mini are not supported. Use USB-C instead or get [BetterDisplay](https://betterdisplay.pro) for full DDC control over HDMI with these Macs as well for free. Software-only dimming is still available for these connections.
 - Some displays (notably EIZO) use MCCS over USB or an entirely custom protocol for control. These displays are supported with software dimming only.
-- The HDMI port of the 2018 Intel Mac mini and 2020 M1 Mac mini prohibit DDC communication. Software control is still available. We recommend connecting the display via the USB-C port (USB-C to HDMI dongles usually work).
 - DisplayLink docks and dongles do not allow for DDC control on Macs, only software dimming is available for these connections.
 
-Note to f.lux users - please activate `Avoid gamma table manipulation` under `Preferences` » `Displays`! This step is not needed if you use Night Shift.

+- f.lux users: please activate `Avoid gamma table manipulation` under `Preferences` » `Displays`! This step is not needed if you use Night Shift.
+- [BetterDisplay](https://betterdisplay.pro/) users: either activate `Avoid gamma table manipulation` in MonitorControl or turn off `Allow color adjustments` in BetterDisplay (under Settings/Displays/Overview). You might want to disable native keyboard control either in MonitorControl or BetterDisplay, depending on which app you want to use for brightness control and dimming.
