HDMI in-ports vs HDMI out-ports (possibly related to damagedmonitor HDMI OUT to OUT)

Why does the Denon A/V Receiver 1909 have a difference in labelling at the back ?
At the back there are 4 HDMI ports, all of same connector type, all female or male... no difference. These all appear to be female.
3 ports are labelled as "in"... for example tv/dvd/hdp.
1 port is laballed as "out/monitor".
They're labeled that way because that's how the three-way monitor switch
is wired. It doesn't matter which one you connect first, but if you
connected connected, say, a TV set, a DVD player, and a monitor to the
three switches labeled "in", you wouldn't see anything on the monitor
because those sources get switched to the "out" port, where you have
nothing connected.
HDMI is designed for consumers who don't read instructions to use, so
it's OK to "hot plug" them.
