Appendix 3 - VNC viewer connection options

When you are connecting to the ServSwitch CX with IP using the VNC viewer, a number of options are available.

Click here to access the options

There are six tabbed pages of options:

Colour/Encoding

Inputs

Scaling

Misc

Identities

Load/Save

IMPORTANT: If you make any changes to the options given here and wish to retain them for successive connection sessions, you must save the changes.

To do this, change to the ‘Load/Save’ tab and click the ‘Save’ button within the ‘Default’ section.

Colour/Encoding

Auto select

When ticked, this option will examine the speed of your connection to the ServSwitch CX with IP and apply the most suitable encoding method. This option

is suggested for the majority of installations.

Preferred encoding

There are three manually selectable encoding methods which are accessible when the Auto select option is unticked.

ZRLE – This is a highly compressed method that is best suited to slow modem connections.

Hextile – This method offers

better performance than the ZRLE when used over a high speed network because there is no need for the ServSwitch CX with IP to spend time highly compressing the data.

Raw – This is a primitive, uncompressed method that is mainly used for technical support issues. You are recommended not to use this method.

Colour level

This section allows you to select the most appropriate colour level for the speed of the connection to the ServSwitch CX with IP. Where the connection speed is slow or inconsistent there will be a necessary compromise between screen response and colour depth.

Full – This mode is suitable only for fast network connections and will pass on the maximum colour depth being used by the host system.

Medium (256 colours) – This mode reduces the host system output to a 256 colour mode and is more suitable for ISDN and fast modem connections.

Low (64 colours) – This mode is suitable for slower modem connections and reduces the host system output to 64 colours.

Very low (8 colours) – This mode provides very rudimentary picture quality and hardly any speed advantage over the 64 colour setting. You are recommended not to use this mode.
