By default, a VNC server will listen for connections from a VNC viewer on TCP port "5900+N", where N is the "Display Number" (usually just zero). So a VNC server setup for Display-0 will listen on TCP-5900, Display-1 is TCP-5901, etc.

Additionally, the VNC server will listen for connections from a web-browser on TCP port "5800+N", where N is as above. If you point a web-browser to this port, the VNC server will automatically provide a Java VNC viewer that runs right in your web-browser. This Java Viewer will then exchange data with the VNC Server on the same ports a normal VNC Viewer would use: "5900+N".

Lastly, if you start a "server-initiated connection" to a Listen-mode Viewer (this is a pretty advanced mode), the connection will be to TCP port "5500+N" on the Viewer.

sirbounty, I thought by default the display should be 0, so I should use 5900 right?

Supports up to 4K resolution!

The VS192 2-Port 4K DisplayPort Splitter is perfect for anyone who needs to send one source of DisplayPort high definition video to two or four DisplayPort displays. The VS192 can split and also expand DisplayPort audio/video signal on two or four DisplayPort monitors.

sirbouty is right.  5900 is correct answer most of the time, unless you change it or use multiple displays.

Sorry for the delay there - yes, if it's set with defaults, 5900 is your port #.
Thanx infotrader. :D
