A command-line tool for reading EDID data from connected display devices, providing support for configurations like resolutions and refresh rates.
read-edid is an open-source command-line utility for reading Extended Display Identification Data (EDID) from connected display devices like monitors, TVs, and projectors. It is commonly used on Linux systems to help get detailed information about display capabilities to assist in troubleshooting graphics and display issues.

Some key uses of read-edid include:
As read-edid provides easy access to detailed EDID information from the command-line interface, it can eliminate guesswork and manual checking of display specifications. The tool is often used in Linux display server configuration, creating Xorg configuration files, debugging display managers, and identifying issues with graphics drivers. It's simple interface and focused capability make it a useful tool for Linux administrators, developers, and power users.
