Those are messages the screen is putting up. Not the computer...

To my knowledge many monitors have some variation on that. My old one had a little thing pop up that moved around the screen for a minute or 2 before it actually suspended itself. Would do the same on power on if it didn't have an active input or connection.

Yeah, that's just the screen. By that point the computer has already shut down, and the screen is telling you that it is not detecting any signal.

Thank you both my friends!

Was waiting for those messages to finish off.
But now, i can "just it down" quicker.
