The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

The contrast ratio is the proportion between the brightest and darkest luminance a display can produce, expressed as a simple ratio such as 1000:1. It indicates how well a screen can differentiate light from dark areas, affecting image clarity and color depth.

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 horizontal synchronization frequency indicates the rate, expressed in kilohertz (kHz), at which a display or projector synchronizes its horizontal scan lines. It represents how many horizontal cycles occur per second and helps users understand the refresh behavior of the device.

The horizontal keystone correction angle specifies the range of degrees by which a projector or screen can adjust horizontally to correct image distortion without loss of clarity. It is expressed as a minimum‑maximum value, such as –30° to +30°, and applies to any device that supports keystone adjustment.

The classification or technology of a lamp, such as LED, halogen, incandescent, laser, or other variants. The value is a textual label that identifies the light source used by the product and does not include units or numeric quantities.

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

The highest horizontal synchronization frequency that a display or video device can support, expressed in kilohertz (kHz). It indicates the maximum rate at which horizontal scan lines can be refreshed, affecting video resolution and refresh performance.

The highest rate at which a display or projector updates its image vertically, expressed in hertz (Hz). It indicates the maximum vertical refresh frequency that the device can support, affecting image stability and motion clarity.

The lowest vertical synchronization frequency at which a display or projector can refresh its image, expressed in kilohertz (kHz). It indicates the minimum rate of line scanning per second and helps users assess compatibility with video sources and performance expectations.

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 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 it is in powersave mode, expressed in watts (W). It represents the minimal energy usage when the product is powered on but not actively performing tasks, and can be used to estimate idle consumption or compare efficiency across similar products.

The type of electrical supply that powers the device, such as mains electricity, batteries, USB power, or a combination of these options.

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 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 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.

The type(s) of USB connector(s) present on a device, such as Micro‑USB, USB Type‑C, USB Type‑A, or combinations thereof. This attribute indicates the physical ports that can be used for data transfer, charging, or peripheral connectivity.

The mass of the product expressed in a standard unit such as grams or kilograms. It represents how heavy the item is and can be used for shipping calculations, handling instructions, or consumer information.
