I'm afraid the only reliable technique I've found is to logout and login
again. Neither xrandr --output --auto nor arandr reliably do the right
thing for me, though they often do with some fiddling.
This is usually viewed as a "not i3" issue, which, while technically
correct, of course doesn't address the point you make that coming from
many other environments this is automatic and so we don't see it.

Hi all,--
thank you all for the replies. I often connect my laptop to monitors
or beamers I haven't connected before. Using the methods suggested
below, I would need to use xrandr to identify the monitor name and
resolution and then issue the right command to mirror. This is a bit
of an overkill. I am coming from Unity, and in that DE all of that is
done automatically by the Settings application. Isn't there some
similar application for i3?
Thank you.

May I suggest using arandr in a first step. This gives a good GUI to
understand what theses xrandr commands do.
You will see that to mirror displays you need to overlap them in
arandr, and set them to the same resolution.
Afterwards, you can write tailored xrandr bindings for your preffered
setups.

I typically use xrandr to switch configurations, and then bind each
configuration to a shortcut. Examples:
# Turn on just one screen:
bindsym $mod+comma exec "xrandr --output eDP1 --off --output DP1 --auto"
bindsym $mod+Control+comma exec "xrandr --output eDP1 --auto
--output DP1 --mode 1920x1080"
# Select a particular resolution
bindsym $mod+period exec "xrandr --fb 1920x1080 --output eDP1 --mode
1920x1080"
# This will automatically activate all monitors
bindsym $mod+slash exec "xrandr --auto"
Make sure to replace eDP1, DP1, or HDMI3 with the actual monitor
names returned by xrandr.
One issue I run into is that if I have my laptop docked with a main
monitor on and the laptop monitor off, if the laptop is locked and I
undock it, the screensaver doesn't turn the laptop monitor on, so I
have to unlock it with no visual feedback.

Hi all,
I would like to mirror the screen of a laptop with an external
monitor, for instance to have a presentation. In other DEs this
is usually provided by an Fn key combination, but i3 ignores
such signals. And is it possible to complete switch off one of
the monitors?
Thank you.
