Nick Couchman commented on GUACAMOLE-288:
-----------------------------------------
[~kano90]: No, no news - the JIRA issues will get updated if and when people
have time to work on them.
And, yes, it is a little more complicated with a web browser to implement
multi-monitor support, even if the underlying RDP library supports it.
Currently Guacamole uses the available browser window space as the dimensions
for the available screen area that it uses to display the remote connection.
Implementing multi-monitor support in Guacamole would, first, require the
ability to detect whether or not the client has multiple monitors attached.
This isn't quite as straight-forward as it sounds - there's no easy/built-in
way in JavaScript to just query the number of monitors attached. Chrome 66
introduced the Presentation API, which _might_ be able to help with this;
however, that doesn't map 1-to-1 in terms of enabling multi-monitor display -
in fact, using the presentation API would likely just mean "sending" the
Guacamole display over to a different screen, and not spanning across multiple
monitors.
You could have the user configure/specify multiple monitors, but this would
likely end up a very clunky/manual process that would require the user to do
things like specify the location and dimension(s) of the monitors. Hardly the
"seamless" experience we're going for.
So, in the meantime, you have a couple of options:
* Stretch the browser window across multiple monitors, so that Guacamole sees
the dimensions of the total of both (all) monitors. Yes, this is clunky.
* Open multiple windows on multiple monitors and make separate connections.
Obviously this isn't the same as having true multiple monitors.

> Hello,
> I'm wondering if multi monitor support for RDP (and maybe even VNC?) is on
> Guacamole's roadmap? Currently, when we RDP to a workstation with multiple
> displays, we only see the primary display. Can't find any options in the
> connection settings to configure multiple monitors.
> I've found a ticket on the old Jira where a developer suggested it may be a
> trivial fix that involves adding a few flags and then the ticket went quite
> in 2015...so just wondering if this feature is in fact being added and if
> there is any ETA for it?
> Thank you
