# Council Decision of 13 November 2012 on the signing and conclusion of the Agreement between the Government of the United States of America and the European Union on the coordination of energy-efficiency labelling programmes for office equipment (Text with EEA relevance) (2013/107/EU), Division 1: Tier 1


To qualify as ENERGY STAR, the display must not exceed the maximum On Mode power consumption (PO or PO1) as calculated from the equations below. The maximum On Mode power consumption is expressed in watts and rounded to the nearest tenth of a watt.
Table 1:
Tier 1 On Mode Power Consumption Requirements
Display Category
Maximum On Mode Power Consumption(W)
Diagonal Screen Size < 30 inches
Screen Resolution ≤ 1.1 MP
PO = 6* MP + 0.05* A + 3
Diagonal Screen Size < 30 inches
Screen Resolution > 1.1 MP
PO = 9* MP + 0.05* A + 3
Diagonal Screen Size 30 - 60 inches
All Screen Resolutions
PO = 0.27* A + 8
Where:
MP Display Resolution (megapixels)
A Viewable Screen Area (square inches)
EXAMPLE: The maximum On Mode power consumption for a display with 1 440 × 900 resolution, or 1 296 000 pixels, a 19 inch viewable diagonal screen size and a viewable screen area of 162 square inches, would be: 9 × 1.296 + 0.05 × 162 + 3 = 22.8 watts when rounded to the nearest tenth of a watt.
Table 2:
Sample Tier 1 On Mode Maximum Power Consumption Requirements
For displays between 30 and 60 inches, resolution must be reported when submitting a product for qualification; however, resolution is not considered when calculating the On Mode power consumption of these displays.
