Linux Ubuntu Server switch off screen for power savings

I am just doing my first steps with HAS so please be gentle.
I have installes HAS on docker on ubuntu server.
The black screen has the backlight turned all the way to the maximum it seems and I can see in the top left corner bright letters indicating:
Ubuntu 24.04.2 LTS server tty1
server login:

I want this to turn completely dark for power saving purpouses.
can you please guide me in the right direction?

This might work:

Why not turn off screen and use ssh?
I only use monitor for catastrophic failure of network or new server setup

Difficult on a laptop

this did indeed work, thank you.
I thought I didn’t like it because the screen doesn’t come on on any input but for what would I need that?
When I update things (apt-get update …) then the screen comes on sometimes and goes dark again after the timer has expired.

is there a command to switch on the screen in case that I want to input something directly on the server?
