I'm happy that WinVNC includes extended-desktop support. But would it
be possible to specify in the server which monitor to serve, rather
than serving the entire extended desktop?
When I do presentations, I hook up my laptop to a projector. I then
extend the desktop across both monitors. The presentation software
puts slightly different things on each display.
* The primary (laptop) display shows not only the slide I'm
projecting, but also a "filmstrip" of the available slides and some
controls. This way I can jump around the presentation easily.
* The external display, however, just shows the current slide. There
are no window borders, scroll bars, or anything.
My idea is this: use VNC to mirror the external display on other
computers. This would allow me to run the presentation "untethered."
That is, I'd be free to roam around the room, using VNC over the wifi
connection to remotely display the presentation on another computer
which, in turn, would be connected to the projector.
I have a couple of ideas of how this could work on the server side.
In the VNC Server options, the user would be able to specify whether
they wanted to server the entire extended desktop (as is done in the
latest versions of the server), or pick which monitor to serve. Being
able to select only one monitor would cut down on the number of updates.
Perhaps the various options could be mapped to TCP ports. Say, 5900
for the whole extended desktop, 5901 for monitor 1, 5902 for monitor
2, etc.
Taking this idea a step further, it might be handy to be able to
serve an arbitrary portion of the overall desktop. Let's say I only
want clients to be able to see one particular part of my screen. The
VNC Server options could display a small representation of my desktop
and I'd drag a marquee to specify which portion to serve.
Is any of this feasible?
