Epson ET-5800 - How to have the display turned off, until I push the power button

[epwul70]

My 1st message here...
Epson ET-5800 - USB - Windows 10 x64 (still)

Default behavior is that the display uselessly turns on at every scan or print.
I may set it to be turned on for -say- 1 minute, but I have not found a way to have the display turned always off.
So, as said, printing, scanning, it is uselessly turning On-Off, On-Off, On-Off...

What I did so far:
1. Display > Settings > General Settings > Basic Settings > Week from Sleep > Wake with LCD Touch > OFF
2. Display > Settings > General Settings > Basic Settings > Power Off settings :
Power off if Inactive: OFF
Power Off if Disconnected: ON
3. Display > Settings > General Settings > Basic Settings > Sleep timer set to 1 minute

My guess is that it is impossible to have display Off by default (ignoring printing / scanning), maybe I overlooking something?

Thanks!
