How to configure the default settings of non-stop screen and non automatic screen lock？？

I tried to execute:

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target 

it can only solve the problem of not entering sleep mode！！！
But the screen will still go black,
So how to set the default black screen never???

In Gnome settings-> power there should be a "Automatic Screen Blank" toggle which you can switch to disabled. I checked this in a quite new Gnome version (48), not sure what version you have.
