Billedet på en skærm er sammensat af røde, grønne og blå prikker. Jo tættere prikkerne er, jo højere opløsning. Afstan- den mellem to prikker i samme farve kaldes for 'Dot Pitch'. Enhed: mm

Skærmen skal gentegnes adskillige gange pr. sekund for at skabe og præsentere et billede for brugeren. Frekvensen for disse gentagelser pr. sekund kaldes for den vertikal frekvens eller opdateringshastighed. Enhed: Hz

Eksempel: Hvis det samme lys gentages 60 gange pr. se- kund, betragtes det som 60 Hz.

Tiden for scanning af én linje, der forbinder den højre kant med den venstre kant af skærmen (vandret) kaldes for den horisontale cyklus, Den inverse værdi af den horisontale cyklus kaldes for den horisontale frekvens. Enhed: kHz

Visning af de horisontale linjer på skærmen fra øverst til ne- derst i rækkefølge kaldes for non-interlace-metoden, mens visning af de ulige linjer og derefter de line linjer i rækkefølge kaldes for interlace-metoden. Non-interlace-metoden an- vendes på størstedelen af skærmene for at sikre et klart billede. Interlace-metoden er den samme, som der an- vendes i tv-apparater.

Dette er en funktion, der giver det bedste kvalitetsskærm- billede for brugeren ved at gøre det muligt, at computeren og skærmen automatisk udveksler informationer. Denne skærm overholder den internationale VESA DDC-standard for Plug & Play-funktionen.

Antallet af vandrette og lodrette prikker der anvendes til at sammensætte skærmbilledet kaldes for 'opløsningen'. Dette tal viser skærmens nøjagtighed. En høj opløsning er velegnet til udførelse af flere opgaver, da der kan vises flere billedinformationer på skærmen.

Eksempel: Hvis opløsningen er 1920 x 1080, betyder dette, at skærmen består af 1920 horisontale prikker (horisontal opløsning) og 1080 vertikale linjer (vertikal opløsning).

Denne funktion udsender klangfuld og levende 3D-lyd som ved 5.1 kanals højttalere, men bruger kun 2 højttalere. Det har en god virkning, når der udsendes stereosignaler.
