Frequently asked questions

Hardware requirements, background operation and switching problems.

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.

Why is the screen black after a command is sent?

The message confirms that the command was sent, not that the monitor is displaying a picture. The monitor may be asleep, the video signal may not be connected yet, or the computer may not be outputting to that monitor.

Does it keep running after I close the window?

Yes. It stays in the macOS menu bar or Windows system tray. Use the app’s Quit option to stop it.

How do I report a problem?

Include monitor models, the switching direction, steps to reproduce and exported diagnostic records. Email [email protected] or open a GitHub issue.
