The new Philips Brilliance LCD computer display has a sensor that can detect people in front. While TVs like the latest Sony Bravias can detect people too, this seems to be the first for a desktop monitor.
Their PowerSensor function works independently of the operating system, and basically allows you to save energy: Everytime you go away from your computer, the monitor will dim and reduce its power consumption by 50%. Hopefully, this simple but great technology will become a standard feature in every monitor in a not-so-distant future. [PocketLint]
