What i mean is that only someone who has access to a user name on a pc can see the screen - others see a blue screen or nice country picture). This would solve many a domestic problem i'm sure (lol).
But is it possible, like sunglasses are polarised and only let light in a certain way, can someone come up wit a monitor that recognises the users and limits their field of view to what's on screen.
Devious i know but with family and children aout wouldn't that be utopia?
