When I lock screen, the display does turn black but the display isn't completely off. There is some light coming out of the display in screen lock mode but it get turned off when inactive for 10 minutes as configured from Brightness and Lock setting.

I tried xset dpms force off which completely turn off the display.

Is there any way that when I press Ctrl + Alt + L to lock screen, the screen get locked and the display is completely turned off saving some power.

Go to System Settings --> Keyboard --> Shortcuts,

Create a new Custom Shortcut.

Reassign Ctrl + Alt + L to the following command.

bash -c "xset dpms force off; gnome-screensaver-command -l"
