Simple KVM

Control multiple computers using one set of Keyboard, Mouse and Monitor.

Full KVMs are quite expensive, particularly ones which supports high resolution / high framerate.

Using this program and a cheap USB Switch (see below), you can achieve the same without spending hundreds of dollars.

Where to download

Releases can be found over in the releases section. (Currenly only for Windows)

What you need

1. Connect your computers to your monitor.

2. Connect your mouse & keyboard to a USB Switch.

3. Run SimpleKVM on one of the computers.

   

You can now switch between the computers using the USB Switch, or a hotkey.

USB Switches

Any USB Switch will do. Here are some examples (no affiliation).

This one supports 4 computers. SABRENT 4 Port USB Switch for $29 USD

This one supports 2 computers. 2 port USB switch for $24 USD

This one supports 2 computers, but only has one input USB. 2 ports for for $3 USD

How does it work?

The program detects when USB devices connect or disconnect, or when hotkeys are pressed. It then tells the monitor to change its input source using a DDC/CI command, which many monitors support.

Does it support multiple monitors?

Yes

Run at startup

1. Open the run window, using win + r
2. Open the startup folder by typing: shell:startup
3. Paste a shortcut to SimpleKVM.exe into that folder
4. Open the properties for the shortcut, and select Run: Minimized
