@ -869,6 +869,18 @@ The 'output' is the name of the RandR output you attach your screen to. On a
laptop, you might have VGA1 and LVDS1 as output names. You can see the
available outputs by running +xrandr --current+.
If your X server supports RandR 1.5 or newer, i3 will use RandR monitor objects
instead of output objects. Run +xrandr --listmonitors+ to see a list. Usually,
a monitor object contains exactly one output, and has the same name as the
output; but should that not be the case, you may specify the name of either the
monitor or the output in i3's configuration. For example, the Dell UP2414Q uses
two scalers internally, so its output names might be “DP1” and “DP2”, but the
monitor name is “Dell UP2414Q”.
(Note that even if you specify the name of an output which doesn't span the
entire monitor, i3 will still use the entire area of the containing monitor
rather than that of just the output's.)
If you use named workspaces, they must be quoted:
