Division 2 Tier 2
United Kingdom
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.

To qualify a computer monitor as Energy Star, it must be tested according to the protocol outlined in Section 4, Test methodology.
