Display Control
Display control describes the process of controlling the display with means other than the hardware buttons.
DDC
DDC – short for Display Data Channel – is a specific way to control the display.
On Linux-based Systems this can be achieved by using the
ddcutil command line interface that can be found in the
package of the same name.
For a graphical user interface ddcui can be used.
After installation it is possible that the system needs to be restarted due to the i2c-dev kernel
module.
