Tier 1 Maximum Allowable Power Consumption: Effective January 1, 2005 |
Y = 38X + 30. Y is expressed in watts and rounded up to the nearest whole number and X is the number of megapixels in decimal form |
<= 4 watts | <= 2 watts |
Tier 2 Maximum Allowable Power Consumption: Effective January 1, 2006 |
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 |
<= 2 watts | <= 1 watt |
Monitor: A commercially-available, electronic product with a display screen and its associated electronics encased in a single housing that is capable of displaying output information from a computer via one or more inputs, such as VGA, DVI, and/or IEEE 1394. The monitor usually relies upon a cathode-ray tube (CRT), liquid crystal display (LCD), or other display device.
Monitor’s On Mode: The product is connected to a power source and produces an image. The power requirement in this mode is typically greater than the power requirement in Sleep and Off Modes.
Monitor’s Sleep Mode: The reduced power state that the computer monitor enters after receiving instructions from a computer or via other functions. A blank screen and reduction in power consumption characterize this mode. The computer monitor returns to On Mode with full operational capability upon sensing a request from a user/computer (e.g., user moves the mouse or presses a key on the keyboard).
Monitor’s Off Mode: The lowest power consumption mode which cannot be switched off (influenced) by the user and that may persist for an indefinite time when a computer monitor is connected to the main electricity supply and used in accordance with the manufacturer’s instructions. For purposes of this specification, Off Mode is defined as the power state when the product is connected to a power source, produces no images, and is waiting to be switched to On Mode by a direct signal from a user/computer (e.g., user pushes power switch).
