(a) The following definitions refer to computer monitors:

1. (1) Computer monitor means an analog or digital device of diagonal screen size greater than or equal to 17 inches and less than or equal to 61 inches, that has a pixel density of greater than 5,000 pixels per square inch, and that is designed primarily for the display of computer-generated signals for viewing by one person in a desk-based environment. A computer monitor is composed of a display screen and associated electronics. A computer monitor does not include:

   1. (i) displays with integrated or replaceable batteries designed to support primary operation without AC mains or external DC power (e.g., electronic readers, mobile phones, portable tablets, battery-powered digital picture frames); or
   2. (ii) a television or signage display.
2. (2) Computer monitor off mode means the computer monitor is connected to a power source, produces no visual information, and cannot be switched into any other mode with a remote control unit, an internal signal, or an external signal.
3. (3) Screen size means the diagonal length from one corner to the corner furthest away of the viewable screen area of a television, measured in inches.
4. (4) On mode means the product is connected to a power source and produces sound and a picture. The power requirement in this mode is typically greater than the power requirement in standby?passive and download acquisition modes.
5. (5) Computer monitor sleep mode means a low-power mode in which the computer monitor provides one or more non-primary protective functions or continuous functions.

6. (6) Enhanced-performance display (EPD) means a computer monitor that has all of the following features and functionalities:

   1. (i) a contrast ratio of at least 60:1 measured at a horizontal viewing angle of at least 85°, with or without a screen cover glass;
   2. (ii) a native resolution equal to or greater than 2.3 megapixels (MP); and

   3. (iii) a color gamut size of at least sRGB as defined by IEC 61966-2 - 1:1999, as incorporated by reference in section 509.61 of this Part. Shifts in color space are allowable as long as 99 percent or more of defined sRGB colors are supported.

7. (10) Gaming monitor means a computer monitor that is capable of adjusting the monitor refresh rate with the frame rate of the video content, and supports a continuously variable refresh rate ranging across a factor of at least 1.75 times the minimum supported (for example, a variable refresh rate of at least 40Hz to 70Hz if the minimum supported refresh rate is 40Hz). The monitor may include incremental hardware-based assistance.
