How do I get VNC to only serve up a specific display in windows?

Solution 1:

The RealVNC 4.1 documentation describes how to use this option. I haven't seen a specific commandline option to activate it, but you can also add it to the registry.

DisplayDevice=<display>

The display device to remote, or empty to remote all displays. The format of display is \\.\<device>. For example, \\.\display1.

You need to set or create the DisplayDevice key in one of the following places, depending on how you're running the server:

If running RealVNC server as a service, set/create the key under
```
HKEY_LOCAL_MACHINE\Software\RealVNC\WinVNC4
```
If running RealVNC server in user-mode, set/create the key under
```
HKEY_CURRENT_USER\Software\RealVNC\WinVNC4
```

I found some indication that this option might be specified on the commandline like this (no guarantees; I can't test this for you):

Winvnc4 -displaydevice=\\.\display1 -portnumber=5900
Winvnc4 -displaydevice=\\.\display2 -portnumber=5901
