Horisontal frekvens
Tiden for scanning af én linje, der forbinder den højre kant med den venstre kant af skærmen (vandret) kaldes for den horisontale cyklus, og den inverse værdi af den horisontale cyklus kaldes for den hori- sontale frekvens. Enhed: kHz
Vertikal frekvens
Som en fluorescerende lampe skal skærmen gent- age det samme billede mange gange i sekundet for at præsentere et billede for brugeren. Denne genta- gelsesfrekvens kaldes for den vertikale frekvens eller opdateringshastighed. Enhed: Hz
