The illumination source used behind a display panel, such as LED, WLED, CCFL or LCD. It determines the brightness, energy efficiency and color accuracy of the screen.

The amount of light emitted by a display or projector, expressed in lumens (cd/m² for luminance). It indicates how bright the screen will appear under typical viewing conditions.

The colour or combination of colours that a product’s outer shell or enclosure 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 case for consumers.

A list of formal recognitions, compliance marks, or standards that a product meets. Each entry may be a single certification (e.g., "RoHS") or a group of related certifications separated by commas (e.g., "CE, FCC, RoHS"). The attribute captures all applicable regulatory, environmental, safety, and quality approvals for the item.

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.

The physical size or shape of a storage disk, indicating the dimensions and mounting format used in computers and other devices. Common values include standard sizes such as "3.5" in., "2.5" in., and form‑factor codes like "M.2 2280" or "mSATA". This attribute helps users identify which drives are compatible with a given enclosure, motherboard, or system.

The type of visual panel or display technology used in a product, such as LCD, LED, OLED, TFT, IPS, AMOLED, or analog. It indicates the underlying technology that determines image quality, color reproduction, power consumption and suitability for different use cases.

The total count of physical DisplayPort input connectors available on the product. This value indicates how many separate DisplayPort interfaces can receive video and audio signals, allowing multiple external displays or devices to be connected simultaneously.

The amount of electrical power that a device consumes during operation, expressed in watts (W). It represents the typical energy draw of the product while it is active and can be used to estimate operating costs or compare efficiency across similar devices.

The electrical power drawn by a device while it is in standby 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 energy rating indicates the relative efficiency of an appliance or electronic device, expressed with letters ranging from A+++ (most efficient) to G (least efficient). This classification allows consumers to compare expected operating costs and environmental impact across similar products.

Specifies the physical configuration or design of a product, such as ATX, Micro‑ATX, Mini‑ITX, tower, case with cover, etc. It describes how the device is built and what mounting or expansion options it supports.

Represents how many headphone or earphone connectors are physically present on the product. The value is a simple integer indicating the total count of headphone ports, regardless of type (e.g., 3.5 mm jack, USB‑C, Lightning) or whether they support audio output only or also input.

The horizontal scan frequency range specifies the minimum and maximum frequencies, in hertz (Hz), at which a display or signal processor can refresh or scan horizontally. It indicates how fast the device updates each horizontal line of the image, affecting overall screen responsiveness and compatibility with various video sources.

A list of natural languages that can be displayed on the screen‑on‑display (OSD) interface of a device, such as a monitor or TV. Each language represents an option available for menu navigation, subtitles, and other on‑screen text.

The type of display panel used in a visual device, such as IPS, TN, VA, OLED, or other technologies that define how pixels are produced and how the screen responds to light and touch. It indicates the underlying technology that affects contrast, color accuracy, viewing angles, response time, and power consumption.

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.

The classification of the power adaptor used with a device, indicating whether it is external or internal, its electrical interface (AC, DC, USB‑Charging, etc.), and any specific form such as integrated or travel adapters. This attribute helps buyers understand how the device receives power and what kind of connector or cable is required.

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

The number of times per second that a display updates its image, expressed in hertz (Hz). It indicates the smoothness and responsiveness of motion on the screen; higher rates generally provide a more fluid visual experience.

The pixel dimensions of a display or image, expressed as width by height (e.g., 1920x1080). It indicates how many pixels are used to render the visual content and is commonly applied to monitors, TVs, projectors, laptops, smartphones, and other devices that output video.

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.

The diagonal measurement of a display screen expressed in units such as inches or centimeters. It indicates the overall visual area available for content and is commonly used to compare monitors, televisions, laptops, tablets, and other electronic devices.

The display panel type used in a visual device, such as IPS, TN, VA, OLED, or other technologies that define how pixels are produced and how the screen responds to light and touch. It indicates the underlying technology that affects contrast, color accuracy, viewing angles, response time, and power consumption.
