Prolite X4868 Motion Sensing Monitor

This 19-inch monitor features an integrated motion sensor that will detect when a person sits in front of the monitor and power it on. I always thought having the monitor in standby mode was sufficient. Any electrical warriors out there know if having the monitor off completely rather than standby mode makes a significant difference? This U.K. monitor will retail for around $300 and confuses us.
