Hostgroups are one way of doing this, and then using the "Hostgroup
Summary" (in the "classic CGIs") as your "dashboard". This will put
the status of the entire hostgroup on one line, but will display the
"worst-case" status of every host in the group. This is useful, but
does not reflect precisely what you may be looking for is you have
hosts that can "cover for one another".
Another alternative would be servicegroups and the use of the
"Servicegroup Summary" page, but that, too, suffers from displaying
the worst-case status in each group.
If showing the worst-case status is OK for you, then either of the
above will work; if not, then you may need to look at things like
check_multi or various types of "business objects" that can be told
to look at aggregate statuses on many hosts.
If you have a large display in a room where lots of folks will see
it, especially non-technical types, you may want to contemplate
something like "Nagvis" for the "Big Board".
Cheers!
