Vertikal frekvens

Et enkelt billede består af mange vandrette linjer. Den lodrette frekvens måles i Hz og angiver, hvordan mange billeder der kan vises i sekundet af disse vandrette linjer. En lodret frekvens på 60 betyder, at et billede transmitteres 60 gange i sekundet. Den lodrette frekvens kaldes også "opdateringshastigheden", og den påvirker, om skærmen flimrer.

Opløsning

Opløsningen er antallet af vandrette pixels og lodrette pixels, som udgør en skærm. Den repræsenterer visningens detaljeringsgrad.

Med en højere opløsning vises en større mængde oplysninger på skærmen, og den er velegnet til at udføre flere opgaver ad gangen.

En opløsning på 1920x1080 består f.eks. af 1920 vandrette pixels (vandret opløsning) og 1080 lodrette linjer (lodret opløsning).

En opløsning på 1920x1200 består f.eks. af 1920 vandrette pixels (vandret opløsning) og 1.200 lodrette linjer (lodret opløsning).

Plug & Play

Med Plug & Play-funktionen kan der udveksles oplysninger automatisk mellem en skærm og en computer for at opnå et optimalt visningsmiljø.

Skærmen anvender VESA DDC (international standard) til udførelse af Plug & Play.
