Synergy has support to connect multiple screen computers to the system. For the time being, each computer will be added to the configuration as one screen, not multiple times.
We understand this limits the positioning options, for example, you can't have something like this:
Server Monitor 1 | Client Monitor 1 | Server Monitor 2
But you can have something like this:
Server Monitor 1 | Server Monitor 2 | Client Monitor 1
If you have any other special combination of the position of your monitor and want to find out if Synergy can accomplish this using a "manual" configuration, please contact support and provide a picture or diagram of your monitor layout.
