Förinställda bildskärmslägen

Om signalen som överförs från datorn är densamma som följande förinställningar, kommer skärmen att anpassas automatiskt. Men om signalen är annorlunda, kan skärmen bli tom medan lysdioden som visar eltillförseln fortfarande lyser. Läs i handboken till videokortet och justera bildskärmen enligt följande:

Horisontalfrekvens

Den tid det tar att avläsa en linje som binder ihop högerkanten med vänsterkanten på bildskärmen vågrätt kallas horisontalcykel och horisontalcykelns omvända tal kallas horisontal frekvens. Måttenhet: kHz.

Vertikalfrekvens

I likhet med ett lysrör måste bildskärmen repetera samma bild många gånger i sekunden för att visa en bild för användaren. Frekvensen hos denna upprepning kallas vertikalfrekvens eller svepfrekvens (refresh rate). Måttenhet: Hz.
