If you don't know anything about a display-number, you are most likely on a
M$Window system at both ends and use the defaults: your display number is 0
(zero). Hence you can skip it.
If you see the server-side propperties, you can change the display number.
Basiccaly this changes the used port-number: the display-number is added to 5900
to get the used port number. For the java-web-viewer it is the same: add the
display number to 5800 to get the used port. View the html-source of that page
in your browser and see it uses port 5900+display for its communication.
For unix-based vnc-servers (including linux! and apple OS-X?) display number 0
is reserved for the console, just as with X11 (like XFree): that uses port 6000
+ display-number for its communication (from application to display). Hence Xvnc
uses 6000+display, 5900+display and optionally 5800+display.
At the viewer side, you select your remote machine with "<machine>:<display>" If
you only use "<machine>" it defaults to "<machine>:0".
