I have hp monitor which recently changed the way I have to shut down and start up. To start up I need to press the menu button and then it starts, to turn off it varies with sleep message and then it turns off, then without doing nothing the osd lockout message happens and then I push the menu button for 30 secs and then it turns off. When i press the power button it does nothing and when i push the menu button it locks out.
