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

Power saving states are measured with speakers attached but not worked.
The recovery time from off mode to on mode is 3 seconds maximun.
2.7.6
Power Connector
All units shall have an IEC/CEE-22 type male power receptacle.
2.8
Plug & Play(EDID)
The monitor will be capable of sending a VESA standardized EDID file through the DDC (pins 12,
15 of the VGA connector).
