Backlighting is the illumination of a screen e.g. LCD (liquid crystal display). There are several types of backlighting with LEDs, e.g. full array, edge lit.

Size of the display for this product, measured diagonally, usually in inches.

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

Resolution of the display for the system

Brightness is quality of the amount of radiating light emitted from the screen. The brightness rating is measured in candelas per square meter, commonly known as 'nits'.

Type of supported High Definition (e.g. Full HD, 4K Ultra HD).

A screen of a laptop, smartphone, etc., that responds to touch so you can control the interface using your fingers.

The aspect ratio is the ratio of the width of an image to its height. The native aspect ratio is the one which the projector/display is particularly designed for. Images shown in native aspect ratio will utilize the entire resolution of the display and achieve maximum brightness. Images shown in other than native aspect ratio will always have less resolution and less brightness than images shown in native aspect ratio.

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.)

The difference in light intensity between the brightest white and the darkest black.

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.

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.

This is the amount of DVI-I interfaces. Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source to a display device, such as a computer monitor. DVI-D means DVI digital, which means it can only support digital, but not analog.

The device features a socket into which a USB cable can be plugged.

Universal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the interface used for connection, communication and power supply between computers and electronic devices. Every new version - for example 1.1, 2.0, 3.0 - is much faster than the previous one.

An Ethernet LAN (Local Area Network) interface is present, for a wired conection via a cable.

Popular technology that allows an electronic device to exchange data or connect to the internet wirelessly using radio waves.

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.

The creation of a plan or convention for the construction of an object or a system.

Where the product can be placed e.g. indoor/outdoor, horizontal/vertical.

The colour e.g. red, blue, green, black, white.

The product can be used wih VESA mounting interfaces.

Type of mounting e.g. wall mounting.

What the product is used for.

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.

Amount of power used by this model; expressed in watts

The amount of electricity that is consumed when the product is on standby.

Whether or not a processor is built into the device.

A family of processors is a group of processors produced by one company over a short period of time e.g. Intel Pentium processors.

The model number for the processor in a computer.

The clock rate is the fundamental rate in cycles per second (measured in hertz) at which a computer performs its most basic operations such as adding two numbers. There are more factors, like internal memory size, that influence a computer's actual response time.

The number of central processing units ('cores') in a processor. Some processors have 1 core, others have 2 (e.g. Intel Core Duo) or more (e.g. the Intel Xeon E7-2850 has 10 cores).

The amount of memory, usually measured in bytes (e.g. MB, GB), which is installed in the system's hardware.

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 type of video formats that can be used by this device.

The audio formats which this device or software can read/use e.g. MP3, MP4.

The type of image files that the device can use/display e.g. gif, JPEG (jpg).

The measurement or extent of something from side to side.

The distance from the front to the back of something.

The distance from one side of the packaging to the other.

The distance from the front to the back of the packaging.

The distance from the top to the bottom of the packaging.

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 minimum and maximum temperatures at which the product can be safely operated.
