EDIT: (for MacOS) theres Luna or BetterDisplay, they can basically do what I was asking about (making displays and external displays as dark/black as digitally possible. Lots of other cool features but that much i know
Not sure if its a neurodivergent thing but I often want to “turn off” or completely darken the monitor without actually pulling the power.
catch { dont want to just do sound and the tv is left to its boilerplate/ad-dled idle nonsense }
I like how on certain devices if you have low power mode on and you AirPlay, it goes completely dark after a moment, I’d like to something like that but for computer. Sort of like a non-screensaver screensaver that doest lock or anything but lets me recreate when TVs used to let you turn of the display
Not sure if I understand you, but most modern OSes switch off the monitor after a few minutes of idling.
Do you mean “picture mute” like some TV’s used to have where the audio kept playing? Definitely a feature I miss for winding down at night. End up turning down all the video settings to nil for 90% of the effect.
On my laptop I have the power button set to turn off the monitor. I use it to listen to stuff to fall asleep to.
I, too would like to know how to do this. I’m running Linux mint on an old Dell latitude laptop
If you’re on linux with X11, you can run
xset dpms force offto turn the monitor off. Either call manually in a terminal or add to scripts where needed. (I assume wayland probably has something similar too, but I don’t know what it is specifically.)Most desktop environments already have a GUI-based way of setting an idle time-out if that’s what you’re looking for; this is a way to call it immediately.
Wayland has similar via busctl . I will have to lookup what my KDE connect commands are
That’s a feature on LG oled TVs.
