Power Management
2.7.4.1
Meet VESA DPMS proposal
The monitor must comply with the Microsoft On Now specification, with a minimum of three power
management states, as defined by the VESA DPMS document. The front panel of the monitor must
appropriately display the DPMS state, For example:
DPMS ON :
The power LED is Green
DPMS OFF :
The power LED is Amber
