Display-switch: Turn a $30 USB switch into a full-featured multi-monitor KVM (github.com)

Article summary

The article discusses a software utility called display-switch that turns a $30 USB switch into a full-featured multi-monitor KVM switch. It watches for USB device connect/disconnect events and switches monitor inputs via DDC/CI, allowing users to press one button on their USB switch and connect all their monitors to a different input. The utility is designed to be installed on all computers connected to the monitors and supports platforms including MacOS, Windows, and Linux. Configuration is done through an INI file, and the utility also supports running external commands upon connection or disconnection of USB devices.

What commenters say

• Some readers found the project's description unclear and initially did not understand what a USB switch is or how the software works.
• The software is useful for users who want to switch between multiple computers connected to the same monitor without having to manually switch the monitor's input.
• DDC/CI support is not universal among monitors, and some users reported that their monitors do not support the necessary commands.
• The use of a USB switch with the software can simplify the process of switching between computers, but may require additional setup and configuration.
• Some users have had success using the software with their monitors, while others have reported issues with compatibility or functionality.
• The availability of DDC commands can depend on the cable or adapter used to connect the monitor to the computer.
• Users with monitors that do not support DDC/CI may need to use alternative methods to switch inputs, such as manual switching or using a different type of switch.
