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 Blue
DPMS OFF :
The power LED is Amber
