Electronic displays

A display/monitor is a commercially available product that has a display screen and associated electronics, often encased in a single housing. Its primary function is to display visual information from:

  1. a computer, workstation or server via one or more inputs;
  2. external storage (e.g., USB flash drive, memory card); or
  3. a network connection.

There are four main types of electronic displays eligible for ENERGY STAR® certification.

Monitors
A monitor displays a computer's user interface and open programs, allowing the user to interact with the computer, typically using a keyboard and mouse. Monitors typically have a diagonal screen size greater than 30.6 centimeters (12 inches) and a pixel density greater than 770.8 pixels per square centimeter (pixels/cm2) (5,000 pixels per square inch)

Enhanced-performance displays
These are computer monitors that have all of the following features and functionalities:

  • a contrast ratio of at least 60:1 measured at a horizontal viewing angle of at least 85 degrees, with or without a screen cover glass
  • a native resolution greater than or equal to 2.3 megapixels (MP)
  • a colour gamut of at least standard red, green, blue (RGB) as defined by IEC 61966 2-1 (technical standard for colour management)

Digital picture frames
These electronic devices are used to display digital images. Typically the diagonal screen size is no more than 30.6 centimeters (12 inches). Models may also feature a programmable timer, occupancy sensor, audio, video, or Bluetooth or wireless connectivity.

Signage display
This commercial signage is found most often in public areas, including retail or department stores, restaurants, museums, hotels, outdoor venues, airports, conference rooms or classrooms. These electronic devices typically have a diagonal screen size greater than 30.6 centimeters (12 inches) and a pixel density less than or equal to 770.8 pixels per square centimeter (pixels/cm2)(5,000 pixels per square inch).
