VNC SC Commands

Posted on 10.03.201303.03.2019 by Milan

Is there a way to set the default Connection Options, specifically, setting the number of colors to 64 so that whenever a client connects, I don’t have to manually change the color number every time?


Start… Run… cmd
start vncviewer /noauto /64colors /listen 5500

Start… Run…
d:\uvnc\vncviewer.exe /noauto /64colors /listen 5500

Start… Run…
“%programfiles%\UltraVNC\vncviewer.exe” /noauto /64colors /listen 5500

open notepad and copy one line of above and save as … vncviewer.bat


Found some of the parameters that can be passed to the server side of SC.

Code:

-service -servicehelper -run -install -sinstall -remove -reinstall -settings -defaultsettings -about -kill -connect -multi -fus -autoreconnect -id -plugin -password -noregistry -notrayicon -readonly -username

Some of them are pretty self explanatory, but others aren’t. I’ll see if I can dig a list of what/how we can use them (for example, the “-settings” one)


applicable only for 32 bit display adapter
Set your Control panel… display … tab Settings… Color quality
select highest (32bit) (nor 24 bits)

then your vncviewer convert to 8 bits colors and you can see the new 64 colors.

known limitation:
if your card support only 24 bit colors, like Intel Graphic 865 chipset onboard., you have no luck.
