monitorcontrol 1.3

Monitor controls using MCSS over DDC-CI.

Python monitor control using the VESA Monitor Control Command Set (MCCS) over Display Data Channel Command Interface Standard (DDC-CI).

Supported Platforms

• Linux

• Windows

The Virtual Control Panel (VCP) is re-implemented once per platform. The monitor class receives a VCP as an argument and uses the VCP for all monitor controls.

Installation

Simply install with pip.

pip3 install monitorcontrol

Manual Installation

Clone (or download) and install the package.

git clone https://github.com/newAM/monitorcontrol.git
cd monitorcontrol
python3 setup.py install

Usage

Example using context manager:

from monitorcontrol import get_monitors

for monitor in get_monitors():
    with monitor as m:
        # set backlight luminance to 100%
        m.luminance = 100

Example using open and close:

from monitorcontrol import get_monitors, VCPError

for monitor in get_monitors():
    try:
        monitor.open()
        # put monitor in standby mode
        monitor.power_mode = "standby"
    except VCPError:
        print("uh-oh")
        raise
    finally:
        monitor.close()

Known Problems

• Will not work on Windows if you have more than one physical monitor per handle.

• Limited MCCS commands implemented, only back-light and power modes are available. Please open an issue or pull request if you would like additional controls.
