The type of display panel used in a visual device, such as LED‑backlit LCD, IPS, TN, VA, OLED, or AMOLED. It indicates the underlying technology that determines image quality, color accuracy, viewing angles, response time and power consumption.

The total amount of electrical energy a product consumes during 1,000 operating hours, expressed in kilowatt‑hours (kWh). This metric allows comparison of energy efficiency across devices regardless of their typical usage patterns.

The energy efficiency class indicates the relative performance of a product, expressed with letters ranging from A+++ (most efficient) to G (least efficient). It allows consumers to compare expected operating costs and environmental impact across similar items.

The energy efficiency scale indicates the relative performance of a product, expressed with letters ranging from A+++ (most efficient) to G (least efficient). It allows consumers to compare expected operating costs and environmental impact across similar items.

Indicates whether a product contains any heavy metals such as mercury (Hg), lead (Pb) or cadmium (Cd). The value is typically a comma‑separated list of the detected metal names, or the string "Yes" if none are present. This attribute helps consumers verify compliance with environmental and safety regulations.

The range of frequencies, expressed in kilohertz (kHz), over which a device can process or display horizontal signals or scan lines. It indicates the minimum and maximum operating frequencies for horizontal scanning operations.

A classification that indicates the target audience or use case for a product, such as Business, Gaming, Home & Office, Education, etc. It helps customers quickly identify which products are best suited to their needs.

The highest electrical power that a device can draw or consume during operation, expressed in watts (W). It represents the peak energy usage of the product and is useful for estimating maximum power requirements, comparing efficiency across similar devices, and ensuring compatibility with power supplies.

The proportion between the width and height of a screen or image, expressed as two numbers separated by a colon (e.g., 16:9). It indicates whether content is designed for widescreen, square, or other aspect ratios and helps users match devices to their media formats.

The percentage of the National Television System Committee (NTSC) color spectrum that a display or video device can reproduce, relative to the full NTSC standard. Values close to 100 % indicate that the product can render almost all colors defined by NTSC, providing accurate and vibrant visual output.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The pair of horizontal and vertical dimensions in millimetres that a product supports for VESA mounting (e.g., "100 × 100 mm"). This value indicates the exact hole spacing required by a mounting bracket to secure the device. It is used for monitors, TVs, projectors and other display equipment that can be wall‑mounted or attached to stands.

The specific technology used to construct the display panel, such as IPS, TN, VA, OLED, or LCD. It indicates how pixels are controlled and affects image quality, color accuracy, viewing angles, and power consumption.

The range of relative humidity (expressed as a percentage) within which the storage device is designed to operate reliably. Values are given as a minimum–maximum interval such as "10 - 90 %" and indicate the acceptable environmental moisture level for optimal performance.

The range of temperatures in which a device can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

The pixel dimensions that a device can output or support, expressed as width by height (e.g., 1920x1080). It indicates the maximum resolution available for display content on the product.

A list of environmental, safety or quality certifications that a product has obtained from recognized authorities. Typical entries include RoHS, ENERGY STAR, CE, WEEE, TCO Certified, FCC, and other industry‑specific standards.

The minimum and maximum angles, expressed in degrees, that a monitor can be tilted or adjusted vertically while maintaining acceptable performance or usability. It indicates the tilt limits for displays such as monitors, stands, or other adjustable equipment.

The range of vertical scan frequencies that a display device can support, expressed in hertz (Hz). It indicates the minimum and maximum refresh rates at which the screen updates vertically, affecting visual smoothness and stability.
