The visual appearance or texture of a product’s display surface, such as matte, glossy, or satin. It indicates how light reflects off the screen and can affect glare, visibility, and aesthetic preference for users.

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 or virtual display output connections available on a device, such as HDMI, DisplayPort, DVI, VGA, or USB‑C ports that support video output.

Indicates how many DVI connectors are present on the product. The value is a simple integer representing the total count of DVI ports, regardless of type or version.

The dynamic contrast ratio is the proportion between the maximum and minimum luminance a display can produce while operating under normal conditions, expressed as a simple fraction such as 1200:1. It reflects how well a screen can differentiate light from dark areas during typical use, influencing perceived image quality.

The energy efficiency class indicates the relative energy performance of a product, expressed with letters ranging from A+++ (most efficient) to G (least efficient). It allows consumers to compare expected operating costs and environmental impact across similar items.

Indicates whether the product includes an Ethernet LAN interface for wired network connectivity, allowing data transmission over RJ‑45 or compatible cables.

The pixel dimensions of a screen’s display expressed as width by height (e.g., 1920×1080). It indicates the number of pixels that can be shown on the monitor or device, affecting image sharpness and clarity.

The ability of a product to change its vertical dimension, typically measured in millimetres, centimetres or inches. It indicates whether the user can raise or lower the item and, if so, by how much. This attribute applies to monitors, desks, furniture, stands and other equipment that offer adjustable height.

The intensity of light emitted per unit area from a display surface, measured in candela per square meter (cd/m²). It indicates how bright the screen will appear under typical viewing conditions.

The type of illumination source used behind an LCD panel, such as LED, WLED, or edge‑lit configurations. This attribute indicates how the display is backlit and helps users compare brightness, energy efficiency, and visual quality across products.

A list of the functions or statuses that an LED indicator on a device can display, such as power status, activity, link, and other operational signals.

The highest number of times per second that a display can update its image, expressed in hertz (Hz). It indicates the maximum refresh capability of the device and is useful for comparing visual performance across monitors, TVs, laptops, and other screen‑based products.

Indicates whether the product includes an on/off switch that allows the user to power it on or off manually.

The underlying display panel technology used in a visual device, such as IPS, TN, VA, OLED, AMOLED, or other variants. It indicates the type of liquid crystal arrangement or organic light‑emitting structure that determines image quality, color accuracy, viewing angles and power consumption.

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.

Indicates whether the product can be used immediately after installation without requiring additional configuration or drivers.

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 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.

Indicates whether a product, such as a monitor or other device, can rotate around its vertical axis to adjust viewing angle. A value of "Yes" means the item supports swiveling; "No" means it does not.

Indicates whether a device is configured as a thin client, meaning it relies on a remote server for processing while using only a local display interface. A value of "Yes" means the thin‑client setup is ready for use; "No" indicates that the configuration has not been applied or is not present.

Indicates whether a product can be tilted or adjusted vertically, allowing the user to change its viewing angle. A value of "Yes" means the device supports tilt; "No" means it does not.
