KVM Keyboard & Mouse Not Working? Quick Fix for HDMI & USB Issues
Why Your Keyboard and Mouse Aren't Working
Take a deep breath—this is the most common misstep people encounter when setting up a KVM for the first time.
- HDMI cables carry video signals only; they do not transmit keyboard or mouse data.
- A separate USB cable is required to connect your keyboard and mouse properly.
- Most keyboard and mouse issues can be resolved quickly by checking your USB cable connections.

Step-by-Step: Fix Keyboard and Mouse Issues with Your KVM
Most keyboard and mouse issues occur because users mistakenly believe HDMI cables carry all necessary signals, causing keyboard and mouse not recognized problems. HDMI cables handle only video signals. For proper keyboard and mouse function, follow these clear steps to solve common KVM troubleshooting issues:
- Connect an HDMI cable from each computer to your KVM switch for video.
- Separately connect a USB cable from each computer to the KVM switch.
- Plug your keyboard and mouse into the USB peripheral ports on the KVM switch.
