Maybe. I picked tightvnc when RealVnc was the standard in Fedora.
VncReflector works best with Tightvnc and the BGR233 8-bit format.

"VNC Reflector is a specialized VNC server which acts as a proxy
sitting between real VNC server (host) and a number of VNC clients. It
was designed to work efficiently with large number of clients, but
current version is optimized to work primarily with clients that
request 8-bit color format known as BGR233. Other color formats are
supported too but performance may be worse if there are many such
clients."

What's the difference between tightvnc, realvnc and tigervnc? I
thought tigervnc was like realvnc.The command line args are different
for tight and real. I noticed tiger command line args are like
realvnc.


fl-tt uses tiger for monitor/control and tight for broadcasting (using
vncreflector) as the proxy.
