ddcset is an application for controlling connected monitors over DDC/CI.

Platforms

Currently supported platforms:

  • Linux
  • Windows
    • Windows Monitor Configuration API provides limited DDC/CI support on all GPUs.
    • NVIDIA NVAPI provides improved DDC/CI support for supported GPUs.

Installation

Binaries are available on some platforms. Cargo can also be used to install directly from source:

cargo install --force ddcset

NVIDIA drivers on Linux

The NVIDIA Linux drivers have had broken DDC/CI support for years now. There are workarounds but it seems that it is not currently possible to use DDC/CI over DisplayPort.
