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.

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.

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.
