Figure 44 VNC Connection Options
Note
The VNC Connection Options dialog box varies for different VNC software
releases.
Configure using the following general guidelines:
• Preferred encoding options - Normally the VNC Viewer requests CopyRect,
Hextile, CoRRE and RRE in that order. The selection alters this behavior by
specifying the encoding method to be used before any of the others are tried.
• Allow CopyRect encoding - When selected, VNC Viewer informs the VNC Server
it can cope with CopyRect encoding.
• Request shared session - When you make a connection to a VNC Server, all
other existing connections are normally closed. This option requests that they be
left open, allowing you to share the desktop with someone already using it.
• Deiconify on Bell - Often a beep will sound because you are being notified of
something such as e-mail arriving or a compilation finishing. This selection causes
a minimized VNC Viewer to be restored when the bell character (escape sequence)
is received.
• Disable clipboard transfer - Clipboard changes caused by cutting or copying at
either the VNC Viewer or the VNC Server are normally transferred to the other end.
This option disables clipboard transfers.
• Emulate 3 Buttons (with 2-button click) - When selected, users with a two-button
mouse can emulate a middle button by clicking both buttons at once.
• Swap mouse buttons 2 and 3 - Generally selected by left-handed persons.
• Restrict pixels to 8-bit (for slow networks) - When selected, reduces color depth
for better transmission speed.
• View only (inputs ignored) - Select this option if you only want to monitor the
desktop of the remote thin client but do not want to operate it using the keyboard
and mouse.
• Full-screen mode - Causes the connection to start in full-screen mode.
