# Commission Decision of 22 December 2004 determining the Community position for a decision of the Management entities under the Agreement between the Government of the United States of America and the European Community on the coordination of energy-efficient labelling programmes for office equipment on the revision of Annex C, part II, defining monitor specifications (2005/42/EC), Division 2: Tier 2

Extent: E+W+S+N.I.

To qualify as Energy Star, computer monitor models must not exceed the following maximum active power consumption equation: If X < 1 megapixel, then Y = 23; if X ≥ 1 megapixel, then Y = 28X. Y is expressed in watts and rounded up to the nearest whole number and X is the number of megapixels in decimal form (e.g. 1 920 000 pixels = 1,92 megapixels). For example, the maximum power consumption for a computer monitor with 1 024 × 768 resolution (or ,78 megapixels) would be Y = 23 watts and for a computer monitor with 1 600 × 1 200 resolution would be 28(1,92) = 53,76 or 54 watts when rounded up.
