Dp is pixel density equal to the resolution in pixels divided by viewable screen area in inches squared
d is diagonal screen size in inches
r is resolution is screen resolution in megapixels
A is viewable screen area in inches squared
Enhanced-Performance Display: A Computer Monitor that has all of the following features and functionalities: (a) A contrast ratio of at least 60:1 measured at a horizontal viewing angle of at least 85o, with or without a screen cover glass; (b) A native resolution greater than or equal to 2.3 megapixels (MP); and, (c) A color gamut size of at least sRGB as defined by IEC 61966 2-1. Shifts in colorspace are allowable as long as 99% or more of defined sRGB colors are supported.
For models meeting the definition of Enhanced-Performance Display, the following On Mode power allowance is added to the Maximum On Mode Power:
Diagonal screen size <27 inches: 0.30×PON_MAX
Diagonal screen size ≥27 inches: 0.75×PON_MAX
Automatic Brightness Control (ABC): The self-acting mechanism that controls the brightness of a display as a function of ambient light. Displays with ABC enabled by default are tested with ambient light at a level of 10 lux and 300 lux. If the On Mode power at 10 lux is at least 20% less than On Mode power at 300 lux, then the following On Mode power allowance is added to the Maximum On Mode Power: 0.10× PON_MAX.
Displays must meet the following Sleep Mode power requirements that take into account networking, bridging, and additional capabilities. Measured Sleep Mode power must be less than or equal to the following calculation.
Maximum Sleep Mode Power = 0.5 watts + PDN + PADD,
PDN is the sum of applicable Networking and Bridging Power Allowances in watts, as described in the table below, and
PADD is the sum of applicable Additional Capability Power Allowances in watts, as described in the table below.
|Included Types||Power (watts)|
|USB 3.x, DisplayPort (non-video connection), Thunderbolt||0.7|
|Additional Capabilities (PADD)|
|Memory: Flash memory-card/smart-card readers, camera interfaces, PictBridge||0.2|
Displays need not have an Off Mode for certification. For Displays that do offer an Off Mode, measured Off Mode power shall be less than or equal to 0.5 watts.
