This list helps users identify which external sources can be connected to the product.

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.

Indicates whether the product is capable of using Miracast, a wireless display standard that allows mirroring or streaming video and audio from a compatible device to the product without cables.

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 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.

A list of the positions or mounting options where a product can be installed, such as indoor, outdoor, wall, desk, floor, ceiling, or universal. Each value represents a distinct placement scenario that the device supports.

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 projection ratio is the proportion between the width of the projected image and the distance from the projector to the screen, expressed as a simple fraction such as 0.28:1 or 1.5:1. It indicates how far the projector must be placed to achieve a desired screen size and helps users plan installation space.

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 when operating in its low‑power or energy‑saving mode, expressed in lumens (cd/m² for luminance). This value indicates how bright the screen will appear under typical viewing conditions while conserving energy.

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 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.
