IT infrastructure provider Fujitsu Siemens Computers has launched what it claims to be the world's first zero watt monitor. This new technology could save firms around £6 per monitor per year, according to estimates.

The technology works by triggering the power supply to disconnect from the mains when the monitor powers down, said the firm. Power is restored to the display by a small electrical pulse when the PC next sends output to the monitor.

The new monitor could save UK firms approximately £6 per monitor per year, based on typical daily usage of eight hours and 16 hours standby throughout a year, said Fujitsu Siemens. Regular monitors continue to draw power of between one and six watts, even in standby mode, the firm said.

The new power-saving technology will be incorporated initially into the IT vendor's Scenicview Premium Line ECO range in the 20-inch P20W-5 ECO and the 22-inch P22W-5 ECO.
