Just install Synergy, and start switching computers seamlessly.
Synergy does virtually the same thing as a hardware KVM, only using software rather than cables (that’s why it’s also called a virtual KVM switch). But it also does far more than a KVM ever could.
Synergy works with your setup exactly as it is now. Hardware KVMs require extra cabling for each computer, and often a power cable too, greatly cluttering your workspace.
Synergy lets you share any mouse and keyboard with computers running any common operating system. Hardware KVMs, unless they cost thousands, have limited connections and compatibility.
Synergy lets you switch computers just by moving your mouse. Hardware KVMs require a physical button. The change can then take up to 30 seconds, and – especially with cheaper models – can fail altogether.
Synergy automatically swaps keyboard keys to match different computers. You can set up key bindings and shortcuts however you want. No hardware KVM can do anything like this.
2-4 is typical
Limited by the number of ports on the switch
Reach across and press a physical switch.
On more expensive models, use a hotkey (but this may clash with other hotkeys).
Some peripherals may not work well or at all, especially across operating systems.
Required for each mouse, keyboard and computer. May also require its own power cable.
Can be used to share one monitor with multiple devices
Unless you’re paying a lot, expect frequent disconnections
$50 – $100,000
If you need to connect one monitor to multiple computers, you’ll still need a traditional KVM. However, if all you’re looking for is to control several computers with one keyboard and mouse, Synergy is an elegant, reliable and affordable KVM alternative.
