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.

The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.

The ability of a product to change its vertical dimension, typically measured in millimetres, centimetres or inches. It indicates whether the user can raise or lower the item and, if so, by how much. This attribute applies to monitors, desks, furniture, stands and other equipment that offer adjustable height.

The vertical dimension of a product measured from its lowest to highest point, excluding any attached stand or base. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.

The highest number of times per second that a display can update its image, expressed in hertz (Hz). It indicates the maximum refresh capability of the device and is useful for comparing visual performance across monitors, TVs, laptops, and other screen‑based products.

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 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 maximum angular range a product can rotate or tilt around its vertical axis, expressed in degrees. It indicates how far the device can pivot from its neutral position while maintaining functionality and usability.

The number of pixels per inch on a display, expressed as points‑per‑inch (ppi). This metric indicates how sharp and detailed the screen appears, allowing comparison across monitors, smartphones, tablets, and other pixelated devices.

Represents the physical dimensions of a single pixel on a display or imaging device, expressed as width and height in a length unit (e.g., millimeters). This attribute allows comparison of the physical resolution across screens, cameras, and other pixel‑based technologies.
