Why NitTray?
Apple Studio Display and Pro Display XDR do not include physical brightness controls. On macOS, brightness can be adjusted through System Settings, but Windows does not provide built-in controls for these displays.
NitTray adds a simple system-tray slider that communicates directly with the display over USB, allowing you to adjust brightness on Windows 10 and Windows 11.

Yes. During initial setup, NitTray installs a lightweight WinUSB helper that enables brightness control for the Pro Display XDR.What type of USB cable do I need?
Connect your display directly to your PC using a data-capable USB-C or Thunderbolt cable that supports USB 3.1 Gen 2 / 10 Gbps or higher. Power-only cables, or cables without the required data support, may prevent NitTray from detecting the display.Is NitTray free?
