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.

Indicates whether the product has a coating that blocks ultraviolet (UV) rays at 100 % intensity, protecting skin and eyes from harmful exposure.

The main illumination source used by the product, such as LED, laser, CCFL, or other light-emitting technologies. It indicates whether the device uses a single light source or multiple sources and helps users understand the lighting characteristics of the item.

The amount of light emitted by a source, measured in lumens (lm). It indicates the brightness level that can be perceived by the human eye and is commonly used for lamps, bulbs, projectors, and other lighting devices.

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 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 number of distinct languages that can be displayed on the screen‑on‑display (OSD) interface of a device, such as a monitor or TV. It indicates how many language options are available for menu navigation, subtitles, and other on‑screen text, allowing users to choose their preferred language when interacting with the product.

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

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 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.

Indicates whether a remote control is supplied with the product. A value of "Yes" means a remote is included, while "No" indicates that no remote control is provided and the user must obtain one separately.

The method or mechanism used to operate a device remotely, such as infrared (IR), Bluetooth, Wi‑Fi, radio frequency, or wired connections. It indicates how the user can send commands to the product from a distance.

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 projector lamp can provide before it needs replacement, expressed in units of time such as hours or days.

A list of the three‑dimensional video formats that a projector or display device can decode and present to the user. Each value represents a distinct 3D mode such as "Side by side", "Top and bottom", "Frame packing" or "Frame sequential". The attribute helps consumers determine whether their content will be displayed correctly on the product.

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.
