Hi Nicholas, Please submit support requests or trial feedback via http://www.realvnc.com/support.html to ensure a timely response.
This sounds like a recently-discovered issue with the GUI toolkit used by x0vncserver, vncconfig & vncviewer in VNC Enterprise Edition E4.3.x releases. The toolkit in question is optimised for TrueColor displays, and deals with PseudoColor ones by allocating a TrueColor-like palette. Depending upon your requirements, you may prefer to: 1. Run your applications using vncserver/Xvnc, in a virtual X server. This will allow you to use more colours than your server computer's console X server can support. VNC will downgrade the colour level automatically if you need to display the server's contents on the limited display hardware. 2. Wait for the next VNC Enterprise Edition release, which will provide an -owncmap option, allowing x0vncserver to be run with its GUI's palette allocated independently of the default one. It may also be possible, depending upon your graphics hardware, to configure the HP-UX system's console to use TrueColor by default. HP-UX PA-RISC systems usually have a bi-modal framebuffer, capable of both 32-bit TrueColor and 8-bit PseudoColor simultaneously. Since x0vncserver always deals with the default visual, setting the default to the 32-bit format will improve its behaviour.
