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.
