Screen size (inches)

Die Grösse eines Displays wird typischerweise mit der Distanz (in Zoll) zwischen zwei gegenüberliegenden Ecken angegeben. Ein Problem dieser Methode ist, dass zwischen Seitenlängenverhältnissen nicht unterschieden wird obwohl die Fläche bei gleichbleibender Diagonale abnimmt, je weniger quadratisch das Display ist. Beispielsweise hat ein 21'' Bildschirm mit Seitenverhältnis von 4:3 eine Fläche von ca. 211 Quadratzoll, wobei ein 16:9 21'' Monitor eine Fläche von nur ca. 188 Quadratzoll aufweist.

Image resolution

Die Bildauflösung ist ein umgangssprachliches Maß für die Bildgröße einer Rastergrafik. Sie wird durch die Gesamtzahl der Bildpunkte oder durch die Anzahl der Spalten (Breite) und Zeilen (Höhe) einer Rastergrafik angegeben.

Aspect ratio

The aspect ratio of an image is the ratio of the width of the image to its height, expressed as two numbers separated by a colon. That is, for an x:y aspect ratio, no matter how big or small the image is, if the width is divided into x units of equal length and the height is measured using this same length unit, the height will be measured to be y units. Aspect ratios are mathematically expressed as x:y.

Contrast ratio

The ratio of the intensity of the brightest bright to the darkest dark.

Dynamic contrast ratio

The ratio of the luminosity of the brightest and the darkest color the system is capable of producing over time.

Response time (grey-to-grey)

Response time is the time a system or functional unit takes to react to a given input.

Refresh rate

The refresh rate (most commonly the "vertical refresh rate", "vertical scan rate" for CRTs) is the number of times in a second that a display hardware draws the data. This is distinct from the measure of frame rate in that the refresh rate includes the repeated drawing of identical frames, while frame rate measures how often a video source can feed an entire frame of new data to a display.

For example, most movie projectors advance from one frame to the next one 24 times each second. But each frame is illuminated two or three times before the next frame is projected using a shutter in front of its lamp. As a result, the movie projector runs at 24 frames per second, but has a 48 or 72 Hz refresh rate.

Brightness

Brightness is an attribute of visual perception in which a source appears to emit a given amount of light. In other words, brightness is the perception elicited by the luminance of a visual target. This is a subjective attribute/property of an object being observed.

Colour depth

Die Farbtiefe bestimmt eine wesentliche Eigenschaft von Raster- und Vektorgrafiken: die Differenzierung aller Helligkeits- und Farbwerte.
Die maximal mögliche Menge an (Farb-)Abstufungen wird in bit angegeben und benennt damit die Farbtiefe eines Bildes. Diese Abstufungen stellen eine Skala dar, auf der die eigentliche Farbinformation gespeichert wird. Die Farbtiefe ist also die mathematische Basis der tatsächlichen Farbinformation. In der Praxis besitzt ein Bild niemals die Menge an Farben, die der Umfang dieser Skala (Farbtiefe) zur Verfügung stellt.

Eine Farbtiefe von 1 bit würde bedeuten, dass in jeweils einem Farbkanal (am Computer-Bildschirm meist rot, grün und blau) genau zwei Zustände möglich wären. Als Beispiel wären das für den Farbkanal rot dann schwarz und rot. Bei einer Farbtiefe von 2 Bit wären 4 Zustände möglich, also beispielsweise schwarz, dunkelrot, mittleres Rot und hellrot. Bei der gebräuchlichen Farbtiefe von 8 Bit sind 28 = 256 Zustände und damit ebenso viele einzelne Rot-Töne möglich.

Viewing angle (H)

In display technology parlance, viewing angle is the maximum angle at which a display can be viewed with acceptable visual performance. In a technical context, this angular range is called viewing cone defined by a multitude of viewing directions.

Viewing angle (V)

In display technology parlance, viewing angle is the maximum angle at which a display can be viewed with acceptable visual performance. In a technical context, this angular range is called viewing cone defined by a multitude of viewing directions.

Pixel pitch

Pixel pitch is a specification for a computer display or other pixel-based device that describes the distance, for example, between dots (sub-pixels) of the same color on the inside of a display screen. In the case of a color display dot pitch is a measure of the size of a triad plus the distance between the triads.

Integrated speakers

A loudspeaker, speaker, or speaker system is an electroacoustical transducer that converts an electrical signal to sound. The term loudspeaker can refer to individual transducers (known as drivers), or to complete systems consisting of a enclosure incorporating one or more drivers and electrical filter components. Loudspeakers (and other electroacoustic transducers) are the most variable elements in a modern audio system and are usually responsible for most audible differences when comparing systems.

Tiltable

Capable of being inclined.

Pivot function

The display can be rotated for 90°. This may be useful if you work with documents as the format is then near to the document format.

VESA Flat Display Mounting Interface

Das VESA Flat Display Mounting Interface (FDMI) ist ein Standard für Befestigungen von Flachbildschirmen an Wänden, Decken, Tischen oder Fahrzeugen, der je nach Abmessung und Gewicht des Bildschirms mindestens 4 Gewinde für Schrauben vorsieht: Bis Oktober 2002 wurde diese Standardisierung unter der Bezeichnung Flat Panel Monitor Physical Mounting Interface (FPMPMI) geführt.

HDMI type A receptacle

The High-Definition Multimedia Interface (HDMI) is a compact audio/video connector interface for transmitting uncompressed digital streams. It represents a digital alternative to consumer analog standards such as Radio Frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, and VGA.

DisplayPort

DisplayPort is a digital display interface standard (approved May 2006, current version 1.1a approved on January 11, 2008) put forth by the Video Electronics Standards Association (VESA). It defines a new license-free, royalty-free, digital audio/video interconnect, intended to be used primarily between a computer and its display monitor, or a computer and a home-theater system.

Power consumption (standby)

In electrical engineering, power consumption refers to the electrical energy over time that must be supplied to an electrical appliance to maintain its operation. The power consumption is usually a result of power used to perform the intended function of the device plus additional "wasted" power that is dissipated as heat, vibration and/or electromagnetic waves.

Input voltage

Voltage (sometimes also called electric or electrical tension) is the difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts.

Energy efficiency class

According to several different EU Directives (92/75/CEE, 94/2/CE, 95/12/CE, 96/89/CE, 2003/66/CE, et alia) most white goods, light bulb packaging and cars must have an EU Energy Label clearly displayed when offered for sale or rent. The energy efficiency of the appliance is rated in terms of a set of energy efficiency classes from A to G on the label, A being the most energy efficient, G the least efficient. The labels also give other useful information to the customer as they choose between various models. The information should also be given in catalogues and included by internet retailers on their websites.
