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 | |
| Diagonal Screen Size < 30 inches Screen Resolution > 1.1 MP | |
| Diagonal Screen Size 30 - 60 inches All Screen Resolutions |
Where:
Display Resolution (megapixels)
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: watts when rounded to the nearest tenth of a watt.
