How to blank the screen on the console

From NetBSD Wiki

To blank your screen on the console, the command screenblank(1) is what you need. It is part of the base system, so you don't need to install it.

# screenblank

This will activate blanking with a default of 600 Seconds (10 Minutes). If you wish to activate it in another time interval use the -d Option.

# screenblank -d 300
