How can I add more computers to Synergy?

Synergy 1 can configure up to 15 computers (1 server and 14 client computers). Supporting more than 15 computers is possible only by using a manual configuration file, as it is not possible to simply add more than 15 computers to the configuration:

To add more computers using a manual configuration file, follow the steps below:

1. Go to the main Synergy window, File menu, and click on "Save configuration to a file":

In this example, we saved the file to C:\SynergyConfiguration\Synergy.sgc.

2. Open the new Synergy.sgc file in a word document or notepad (or any text editor). The file should contain the following:

-code-section: screens

halfDuplexCapsLock = false

end-/code-

3. As you can see, there are two important sections of the config file, "screens" and "links". Let's place our new computer, "Computer16" right below "Computer11", but first we will first add it in the "screens" section. Right below the "Computer15" description and above "end" we will add:

-code-Computer16:
halfDuplexCapsLock = false
halfDuplexNumLock = false
halfDuplexScrollLock = false
xtestIsXineramaUnaware = false
switchCorners = none
switchCornerSize = 0-/code-

4. Now, we need to add "Computer16" to the "screens" section, for that, we need to do two things: (a) Edit "Computer11" Links and (b) Add "Computer16" links.

(a) As you can see, "Computer11" links are set like this:

-code-Computer11:
right = Computer12
up = Computer6-/code-

We now need to reference that "Computer16" is down of "Computer11". We can do that by adding the link down, like this:

-code-Computer11:
right = Computer12
up = Computer6
down = Computer16-/code-

(b) Add "Computer16" links

Now that we edited "Computer11" links, we need to add "Computer16" to the links section, again, right below "Computer15" and above "end", like this:

-code-Computer16:
up = Computer11-/code-

You now just need to save your configuration file and hit "Apply" on the Synergy application, already configured to use the manual config file, and you're done.

This is just an example on how to add a 16th computer to the layout, but this also applies if your array is configured differently, for example, we are assuming you have rows of 5 monitors. However, let's say you have rows of 10 computers – you can accomplish this using a manual config file. You will just need to change the links section accordingly to set which screen is to the left/right/up/down position.
