Hextile is a good choice for fast networks, while Tight is better suited for low-bandwidth connections.

Use specified compression level for Tight and Zlib encodings. Level 1 uses minimum of CPU time on the server but achieves weak compression ratios. Level 9 offers best compression but might be slow in terms of CPU time consumption on the server side. Use high levels with very slow network connections, and low levels when working over higher-speed networks. The Default value means that the server's default compression level should be used.

Choose a value between 0-9, with 0 being the lowest quality value and 9 as the highest image quality value.

If set to JPEG off, then no JPEG format is used for images.

Cursor shape updates is a protocol extension used to handle remote cursor movements locally on the client side, saving bandwidth and eliminating delays in mouse pointer movement. Note that current implementation of cursor shape updates does not allow a client to track mouse cursor position at the server side. This means that clients would not see mouse cursor movements if the mouse was moved either locally on the server, or by another remote VNC client.

Set this parameter to Disable if you always want to see real cursor position on the remote side. Setting this option to Ignore is similar to Enable but the remote cursor is not visible at all. This can be a reasonable setting if you do not care about cursor shape and do not want to see two mouse cursors, one above another.

Select remote paste shortcut key combinations. Options include setting this option to Alt + V, Ctrl + V, and Meta + V.

CopyRect saves bandwidth and drawing time when parts of the remote screen are moving around. Most likely, you do not want to change this setting.

If set to No, then 24-bit color format is used to represent pixel data. If set to Yes, then only 8 bits are used to represent each pixel. 8-bit color format can save bandwidth, but colors might look very inaccurate.

If set to Yes, then all keyboard and mouse events in the desktop window is silently ignored and is not passed to the remote side.

If set to Yes, then the desktop can be shared between clients. If this option is set to No then an existing user session ends when a new user accesses the desktop.

If set to Yes, then the user can copy text between the VNC client and the server.
