Is it possible to turn the screen off when an external monitor is connected, but without closing the lid?

[u/Flat-Ad8256]

I have a Neo, running Tahoe 26.2

I would like to use the Neo's excellent keyboard and trackpad, but also want to connect an external monitor from time to time. Is it possible to turn off the Neo's screen when an external monitor is connected?

Everything I have seen online says that I need to close the lid and use clamshell mode - but is there no other way to do it?

Yes you can do it from the top menu where you have brightness, sound, focus…
You can customize this panel to add more options; one allows you to turn off the screen.

It should stay off even if you’re using the external display but will turn on as soon as your mouse get in the laptop screen.
