Hi,

you can use arandr to make a shell script to switch the display to a
certain mode.  Plug in the monitor and use arandr to make a setup you
want, and save that.  Then open your config file for openbox and set
the keyboard shortcut for your display key (i.e. XF86Display)
to execute the
<command>
/bin/bash /path/to/scriptname.sh
</command>
while scriptname.sh is whatever you saved the setup as with the correct
path.

arandr is a front-end for xrandr.  So the script is actually using
xrandr to modify your display settings.

I hope this helps.
