The altitude interval (in meters) at which a product or component ceases to function correctly due to environmental factors such as reduced atmospheric pressure, temperature changes, or other elevation‑related effects. The value is expressed as a minimum–maximum range and applies to any device that has documented limits for operation above or below certain heights.

The total count of integrated speaker units present in the product. This value indicates how many separate speaker elements are built into the device, helping users compare audio capabilities across models.

The range of altitudes (in meters) at which a product or component can operate reliably without performance degradation due to changes in atmospheric pressure, temperature, or other altitude‑related effects.

Indicates the preferred or supported orientation of a product, such as landscape, portrait, horizontal/vertical, or other directional settings. This attribute helps users understand how the device can be positioned for optimal use.

The linear measurement from front to back or top to bottom of a product’s packaging, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the packaged item is and can be used for fitting, compatibility, or spatial planning.

The vertical dimension of a product’s packaging measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and helps customers assess how tall the package will be when stored or shipped.

The horizontal measurement of a product’s packaging, expressed in a linear unit such as millimetres or inches. It indicates how wide the package is from one side to the other and helps customers assess fit for storage, shipping, or display.

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.

Represents the physical size of a single pixel on a display, expressed as width and height in a length unit (e.g., millimeters). This attribute allows comparison of the physical resolution of screens or imaging devices that use metric units to describe the smallest visible point.

The purpose indicates the primary function or intended use of a product, such as "Notebook", "Gaming", or "Server". It helps customers quickly identify whether the item matches their needs and can be used for filtering or categorization across different product categories.

The time interval between a stimulus and the corresponding response of a device or system, expressed in units such as milliseconds (ms). It indicates how quickly the product reacts to input or processes data, which is critical for performance-sensitive applications like displays, gaming monitors, and interactive devices.
