Mesure de la diagonale de l'écran du produit, généralement en pouces.

The technology used in the display e.g. plasma, LED.

Résolution de l'écran pour le système.

La luminosité est la qualité de la quantité de lumière rayonnante émise par l'écran. La luminosité est mesurée en candelas par mètre carré, communément appelés "nits".

Type de prise en charge Haute définition (ex : Full HD, 4k Ultra HD).

L'écran du téléphone ou de l'ordinateur, etc., qui réagit au toucher pour que vous controliez l'interface en utilisant vos doigts.

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.

The response time is the time difference between the moment that a source (for example a video card) sends a signal and that equipment (for example a monitor) receives or display the signal. (Used abbreviations: R/F = Rise and Fall.)

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

Maximum horizontal angle at which a display can be viewed with acceptable visual performance.

Maximum vertical angle at which a display can be viewed with acceptable visual performance.

This is the parameter of a picture tube, which specifies the shortest distance between two dots of the same colour. The principle is: the smaller the dot pitch, the better sharpness of image.

What the product is used for.

The computer allows multi-display, which is where multiple physical display devices, such as monitors, televisions, and projectors, are used in order to increase the area available for computer programs running on a single computer system.

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 IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".

Whether or not a processor is built into the device.

The speed that the microprocessor executes each instruction or each vibration of the clock. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The faster the clocks rate, the faster the CPU, or the faster it can execute instructions. Clock Speeds are usually determined in MHz, 1 MHz representing 1 million cycles per second, or in GHz, 1 GHz representing 1 thousand million cycles per second. The higher the CPU speed, the better a computer will perform.

The amount e.g of data which can be stored inside the device.

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.

Weight of the packaged product.

Component of an electronics device, most commonly a television set, DVD player and home theater systems originally used for operating the device wirelessly from a short line-of-sight distance.

The product can be mounted on (attached to ) a wall.
