First, verify all cable connections between the laptops, KVM switch (if used), and monitor. Ensure that cables are securely plugged into the correct ports and that no cables are damaged. Try swapping cables to rule out a faulty cable as the cause of the problem.
If using a KVM switch, ensure it’s properly powered on and that the correct input is selected. Check the KVM switch’s manual for specific troubleshooting steps. If using the monitor’s input switching, make sure you’ve selected the correct input source on the monitor’s menu. Additionally, update the graphics drivers on both laptops to ensure they are compatible with the monitor and KVM switch (if applicable).
Are there any software-based alternatives to using a KVM switch?
Yes, there are software-based solutions that can allow you to control multiple computers with a single keyboard and mouse, effectively mimicking some of the functionality of a KVM switch. Programs like Synergy, Barrier, and ShareMouse allow you to move your mouse cursor between different computer screens, and the keyboard input will automatically switch to the computer where the cursor is located.
These solutions rely on networking between the computers and require software installation on each device. While they offer a cost-effective alternative to hardware KVM switches, they might introduce latency or depend on a stable network connection for optimal performance. They also do not switch the video output, so you would still need to use the monitor’s input switching capabilities to change which laptop’s screen is displayed.
