Terminologi

Dot Pitch

Produktet består af røde, grønne og blå prikker. En mindre afstand mellem prikkerne medfører en højere opløsning. Dot pitch henviser til den korteste afstand mellem prikker med samme farve. Dot pitch måles i millimeter.

Vertikal frekvens

Produktet viser et enkelt billede mange gange pr. sekund (som et lysstofrør, der flimrer) for at gengive et billede, som brugeren kan se. Den hastighed, hvormed et enkelt billede gentages pr. sekund, kaldes for den vertikale frekvens eller opdateringshastigheden. Vertikal frekvens måles i Hz.

F.eks. henviser 60 til et enkelt billede, der vises 60 gange på ét sekund.

Horisontal frekvens

Den tid, det tager at scanne en enkelt linje fra venstre til højre side af skærmen, kaldes en horisontal cyklus. Den inverse værdi af den horisontale cyklus kaldes for den horisontale frekvens. Horisontal frekvens måles i kHz.

Non-interlace tilstand og interlace tilstand

Non-interlace tilstand (progressiv scanning) viser progressivt en horisontal linje fra top til bund på skærmen. Interlace tilstand viser først de ulige linjenumre og derefter de lige numre. Non-interlace tilstand anvendes hovedsageligt i pc-skærme, da den medfører en tydelig skærm, og interlace tilstand anvendes mest i tv.

Plug & Play

Plug & Play er en funktion, der muliggør automatisk udveksling af informationer mellem en skærm og en pc, for at opnå det optimale visningsmiljø. Produktet anvender VESA DDC (international standard) til udførelse af Plug & Play.

Opløsning

Opløsning er antallet af de horisontale prikker (pixels) og de vertikale prikker (pixels), der udgør en skærm. Den repræsenterer visningens detaljeringsgrad. En højere opløsning gør det muligt at vise flere data på skærmen og er praktisk ved samtidig udførelse af flere opgaver.

Eksempel: En opløsning på 1920 X 1080 består af 1.920 horisontale pixels (horisontal opløsning) og 1.080 vertikale pixels (vertikal opløsning).
