LG-Ultrafine-Brightness

A tool to adjust brightness of LG Ultrafine 4k/5K on Windows without the help of Bootcamp. I built my own PC and made this tool to adjust brightness through my PC.

The program sends set feature report to the device to adjust the brightness.

This project is derived from https://github.com/unknownzerx/lguf-brightness.

Thanks @unknownzerx.

The original tool was unable to adjust brightness in Windows 10 and I also made some minor improvements to it like showing current brightness and efficiency while adjusting.

Linux

Please go to this repo https://github.com/velum/lguf-brightness.

Usage

Press '-' or '=' to adjust brightness.
Press '[' or: ']' to fine tune.
Press 'p' to use the minimum brightness
Press '' to use the maximum brightness
Press 'q' to quit.

Build

1. Open the sln file by Visual Studio.
2. Select x64 configuration.
3. Build!

Note that I put the hidapi.dll in the project and if you don't believe it's secure, you can build a new one (x64) and replace it.
