QM2128001

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 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.

The device can be used with 3D technology.

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

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

The colour of the feet, which are the projecting part on which a device/piece of furniture, or each of its legs, stands.

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

Number of VGA (D-Sub) ports (connecting interfaces) in the device. The VGA (D-Sub) connector is a 15 pin connector between a computer and a monitor. It was first introduced in 1987 by IBM.

The product can be used wih VESA mounting interfaces.

Holes on the edge of devices through which a cable lock can be passed, so the device can be locked to a desk etc.

The part of the device that can be adjusted to change the height.

The tilt, which means the angle at which the device is pointing (up or down), can be changed.

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

Instructions, either online, as a computer program or in paper form, to allow you to set up and start using the product quickly.

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.

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