The following script will check every ten seconds to see if the screensaver is enabled, and if it is, turn of the display using the command xset dpms force off.
It also checks to make sure it didn't already turn off the display, so you can unlock the screen without the monitor turning off while you are typing your password.
#!/bin/bash
ALREADY_SHUTOFF="yes"
while true; do
if (gnome-screensaver-command -q | grep "is active");
then
echo $ALREADY_SHUTOFF
if [ "$ALREADY_SHUTOFF" == "no" ];
then
# this command turns off the display
xset dpms force off
fi
ALREADY_SHUTOFF="yes"
else
ALREADY_SHUTOFF="no"
fi
sleep 10
done

For what it is worth:
Super+L (Super is the Windows key on PC, or the command key ⌘ on Macs) locks your screen.
I always have the screen blanker off, but it still activates as I press these keys.
System Settings > Brightness & Lock:
Turn screen off when inactive for: Never.
Lock: ON
Lock screen after: 30 seconds.
