Specifies the focusing behavior of a camera or imaging device, indicating whether it uses automatic focus, manual focus, or a combination such as auto‑manual. The value is expressed as a free‑text string that describes the mode in use.

The specific version of the HDMI standard that a product supports, such as "2.0", "2.1" or "1.4b". This value indicates the capabilities and compatibility of the HDMI interfaces on the device.

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 technology used to generate the image in a projector, such as DMD (Digital Micromirror Device), MLA (Microlens Array) or LCD panels. It indicates how light is modulated and reflected to produce the displayed picture.

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 sound intensity produced by a product while operating in its economic or low‑power mode, expressed in decibels (dB). This value indicates how quiet the device is during energy‑saving operation and helps users assess suitability for quiet environments.

The total count of distinct colours that a display can render, typically expressed in millions or billions. This figure reflects the colour depth and determines how smoothly gradients and subtle hues are reproduced on the screen.

The percentage by which a measurable attribute—such as brightness, contrast, or other performance metrics—deviates from its standard or reference value. It indicates how much the actual measurement is increased or decreased relative to the expected norm.

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 range of temperatures in which a product 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 electrical power drawn by a device while operating in its economy or energy‑saving mode, expressed in watts (W). This value indicates the typical energy usage when the product is set to reduce consumption during normal operation.

The minimum and maximum distances, expressed in metres, at which a projector can display an image on a screen while maintaining acceptable sharpness and brightness. The value is represented as a range (e.g., "1.2 - 10 m"). This attribute helps users determine whether the projector will fit their room size.

The optical method used by a projector to create an image, such as DLP, LCD, LED or 3LCD. It indicates the underlying light‑processing system that determines brightness, color accuracy and overall visual performance.

The amount of light emitted by a projector, expressed in ANSI lumens. It indicates how bright the projected image will appear under typical viewing conditions and allows users to compare brightness levels across different projectors.

The pixel dimensions that a projector can output, expressed as width by height (e.g., 1920x1080). It indicates the native resolution of the projected image and is used to determine compatibility with source content and display quality.

The root‑mean‑square (RMS) power rating of a device, expressed in watts (W). It represents the average electrical power that the product can deliver or consume under normal operating conditions.

The diagonal measurement ranges of screens that the product can project or display, expressed in millimeters and/or inches. It indicates the minimum and maximum screen sizes that the device is designed to handle.

The total operating hours a lamp can provide before it needs replacement, expressed in units of time such as hours or days.

The total operating hours a lamp can provide before it needs replacement when operated in an energy‑saving or low‑power mode, expressed in units of time such as hours.

The proportion between the width and height of a product’s display or image, expressed as two numbers separated by a colon (e.g., 16:9). It indicates whether the content is designed for widescreen, square, or other aspect ratios.

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.

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.

The proportion between the distance from a projector to its screen and the width of the projected image, expressed as a simple ratio such as 2:1 or 1.5:1. It indicates how far the projector must be placed to achieve a desired screen size and is useful for planning installation space.
