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.

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.

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

Technology of touch sensetive screen e.g. dual-touch.

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.

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.

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

The device can be used with 3D technology.

The product includes AMD Freesync Technology for the dynamic synchronization of the graphic card and the monitor in order to avoid screen tearing.

The device contains speaker(s) to produce sound.

Microphone that is found inside the product.

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