The command "ddcutil detect" is used to detect displays connected to the computer and retrieve information about them using the DDC/CI (Display Data Channel/Command Interface) protocol.
DDC/CI is a standard protocol that allows communication between a computer and a display device through the connection cable. It enables the computer to obtain various information from the display, such as model name, manufacturer, supported resolutions, and other display settings.
When you execute the "ddcutil detect" command, it sends a DDC/CI request to each connected display. The displays respond with their respective information, which is then displayed on the terminal.
This command provides a convenient way to get an overview of all the displays connected to the computer and their specific details, which can be useful for various purposes, such as troubleshooting display issues, configuring display settings, or identifying specific display characteristics.
