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

The number of distinct pixels in each dimension that can be displayed. It is usually quoted as width × height, with the units in pixels: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. The higher the number of pixels, the sharper the image.

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

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

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

Display brightness, measured by its Luminance, presented as a figure in candela per square meter (cd/m2). Typical brightness ratings for monitors range from 250 to 350 cd/m2 with a target value of between 80 to 120 cd/m2 being suitable for most displays in a normal viewing environment.

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 graphic resolutions that can be displayed by the device. The graphic resolution describes the width and height dimensions of a display, such as a computer monitor, measured in pixels.

The aspect ratio is the ratio of the width of a shape to its height. For example, 4:3 is common for standard displays and 16:9 is the ratio for Widescreen TV.

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 device can be used with 3D technology.

The device contains speaker(s) to produce sound.

Under which category can the device be positioned in the market, e.g. camera phone.

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

Whether or not the device features a USB hub to connect more than one other device via USB.

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

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.

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.

The type of audio input that the device requires, and the connection needed.

The product can be used wih VESA mounting interfaces.

Amount of power consumed by this model, often expressed in watts (W). Typical values that manufacturers give are power consumption when off, standby/suspended mode, typical use, maximum usage.

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

The voltage of the AC electricity that is inputted into the product.

The button which is pressed to switch the device on or off.
