With synchrony, all the computers on your desktop form a single virtual screen. Synchrony works in conjunction with a KM switch, effectively allowing simultaneous use of all of the monitors on all of the computers. You tell synchrony how many screens you have and their positions relative to one another. Synchrony then detects when the mouse moves off the edge of a screen and jumps it instantly to the neighboring screen via a signal to the KM switch. The computers and KM switch operate as normal, except with the added ability to switch between screens simply by moving the cursor.
In this example, the user is moving the mouse from left to right. When the cursor reaches the right edge of the left screen it jumps instantly to the left edge of the right screen.
You can arrange screens side-by-side, above and below one another, or any combination. You can even have a screen jump to the opposite edge of itself. Synchrony also understands multiple screens attached to the same computer.
If you regularly use multiple computers on one desk, give synchrony a try. You'll wonder how you ever lived without it.
