[dba-Tech] Tight VNC Options

Stuart,

Thanks for that.  I went in to the shortcut and surprise, it already has the
compression stuff set to something, all I had to do was experiment for what
works for me. 

Thanks for pointing that out.

Try setting up shortcuts to it using using commandline options

"C:\Program Files\TightVNC\vncviewer.exe" -compresslevel 9 -quality 0

>From http://www.tightvnc.com/vncviewer.1.html:

-compresslevel level
    Use specified compression level (0..9) for "tight" and "zlib" encodings
(TightVNC-specific). Level 1 uses minimum of CPU time and achieves weak
compression ratios, while level 9 offers best compression but is 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 high- speed LANs.
It's not recommended to use compression level 0, reasonable choices start
from the level 1.

-quality level
    Use the specified JPEG quality level (0..9) for the "tight" encoding
(TightVNC-specific). Quality level 0 denotes bad image quality but very
impressive compression ratios, while level 9 offers very good image quality
at lower compression ratios. Note that the "tight" encoder uses JPEG to
encode only those screen areas that look suitable for lossy compression, so
quality level 0 does not always mean unacceptable image quality.
