Frequently asked questions
What if the system won’t open KVMFlow?
KVMFlow isn’t code-signed yet. On macOS, go to System Settings → Privacy & Security → Open Anyway. On Windows, click More info → Run anyway. See Download and install for all the steps.
Can I use it without a USB switch?
A USB switch is required. It switches the keyboard and mouse; KVMFlow switches the monitor inputs.
Do my monitors need DDC/CI?
Yes. Enable DDC/CI in the monitor menu. Adapters, graphics cards and video connections can also affect monitor control.
Do I need to install it on both computers?
Install and run KVMFlow on both computers. Some monitors only accept control commands from the computer currently displaying a picture.
Can I use multiple monitors?
You can save input mappings for multiple monitors. Each monitor needs DDC/CI support and its own input values.
