How can I improve my slow VNC connection? ("I'm receiving slow performance")

There are a few settings that can be modified in the VNC Viewer and VNC Server to help the situation.
From within the VNC Server properties there are a few desktop optimisation settings you could try changing:

Remove desktop background
Disable user interface
Optimise screen capture (mirror driver)

From within the VNC Viewer there are display options that can be manipulated:

Adapt to network speed
Always use best available color quality

You can also try setting the Relativeptr paramer to True under the expert settings.

Find out the speed of the connection:

The connection speed is displayed within the information on the VNC Viewer remote screen. For a more accurate idea of the speed and quality of the connection, try pinging the ip address of the vnc viewer from the vnc server computer.

From a windows based system:

Start > Run > cmd

ping x.x.x.x where x.x.x.x is the ip address of the VNC Viewer computer.

Please be aware that connections over a wireless network will be slower and less stable than an ethernet connection. Likewise connections over the Internet will be slower than those over the local LAN.
