OK lets admit you connect a display to a computer that runs linux.
The display will show a login screen asking for user and password.
I am logged in via SSH on pts/0
I can now run a program on TTY1 like this
some-program > /dev/tty1 2>&1
But what I am looking for is a possibility to just show my console to tty1 without the user to be able to interfere. I tried:
screen > /dev/tty1 2>&1
but it opened the screen on pts/1 instead ot tty1. I tried
top > /dev/tty1 2>&1
result was a dark screen any hint?
