44 ULTRAVIEW REMOTE 2 INSTALLATION AND OPERATIONS MANUAL
Appendix F – VNC Viewer connection options
When you are connecting to the UltraView Remote 2 unit using the VNC viewer, a number of options are
available.
Click the Options… button
There are six tabbed pages of options:
Color/Encoding
Auto select
When ticked, this option will examine the speed of your connection to the
UltraView Remote 2 unit 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 un-ticked.
• 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 UltraView
Remote 2 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.
Color level
This section allows you to select the most appropriate color level for the speed of
the connection to the UltraView Remote 2 unit. Where the connection speed is
slow or inconsistent there will be a necessary compromise between screen
response and color depth.
• Full – This mode is suitable only for fast network connections and will pass on
the maximum color depth being used by the host system.
• Medium (256 colors) – This mode reduces the host system output to a 256
color mode and is more suitable for ISDN and fast modem connections.
• Low (64 colors) – This mode is suitable for slower modem connections and
reduces the host system output to 64 colors.
• Very low (8 colors) – This mode provides very rudimentary picture quality and
hardly any speed advantage over the 64 color setting. You are recommended
not to use this mode.
