The aspect ratio is the ratio of the width of an image to its height. The supported aspect ratios are the aspect ratios that can be shown by the device.

The different screen sizes which the device can work with.

The maximum length at which an image can be projected.

La différence d'intensité lumineuse entre le blanc le plus clair et le noir le plus foncé.

Le rapport d'aspect est le rapport entre la largeur d'une image et sa hauteur. Le rapport d'aspect natif est celui pour lequel le projecteur/écran est particulièrement conçu. Les images affichées dans leur format d'origine utiliseront toute la résolution de l'écran et atteindront une luminosité maximale. Les images affichées dans un format autre que le format d'origine auront toujours une résolution et une luminosité moindres que les images affichées dans le format d'origine.

Defines in percentage the harmonious spread of the projection

The supported protocols for exchanging analog signals.

Full High Definition (HD) means that a display supports a resolution of 1920 x 1080 pixel, and has a digital TV connection.

The device can be used with 3D technology.

The number of sockets (ports) for HDMI connections. HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed video data and compressed/uncompressed digital audio data from a HDMI-compliant device ("the source device") to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for existing analog video standards.

Digital Visual Interface (DVI) is a video display interface to connect a video source to a display device, such as a computer monitor.

The socket/plug where the DC electricity supply connects to the device.

Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.

A card reader is a device that enables reading and, in some cases, writing data to and from a memory card.

High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection to prevent copying of digital audio and video content as it travels across connections.

The amplitude level of the undesired background noise, usually measured in decibels (db).

Indicates whether this product supports is "plug and play". Plug and play is hardware or software that, after being installed ("plugged in"), can immediately be used ("played with"), as opposed to hardware or software which requires configuration.

AirPlay (previously called AirTunes when it was for audio only) is a proprietary protocol stack/suite developed by Apple Inc. that allows wireless streaming of audio, video, and photos, together with related metadata between devices. Originally only implemented in Apple's software and devices, Apple has licensed the AirPlay protocol stack as a third-party software component technology to manufacturer partners for them to use in their products in order to be compatible with Apple's iDevices.

Type of operating system on a device e.g. IOS on Apple devices, Android for mobile devices.

The version of the operating system used e.g. 4.1, 4.2 for Android.

The device contains speaker(s) to produce sound.

RMS (Root mean square) is a measure of the continuous power required by a device, in particular audio amplifiers and loudspeakers.

Device or software capable of decoding a digital stream of audio e.g. internet radio.
