-- Frequenza orizzontale

Il tempo impiegato per eseguire la scansione di una singola riga da sinistra a destra dello schermo è denominato ciclo orizzontale. Al contrario, il numero reciproco di un ciclo orizzontale è denominato frequenza orizzontale. La frequenza orizzontale è misurata in kHz.

-- Frequenza verticale

Le immagini visibili sullo schermo sono generate mediante la ripetizione della stessa immagine decine di volte al secondo. La frequenza della ripetizione si definisce "frequenza verticale" o "frequenza di aggiornamento" ed è espressa in Hz.
