Ja signƗls, kurš tiek saƼemts no datora, ir tƗds pats kƗ sekojošie Iepriekš iestatƯtie laika režƯmi, ekrƗns tiks piemƝrots automƗtiski. Taþu, ja signƗls atšƷiras, ekrƗns var kƺnjt tukšs, kaut arƯ enerƧijas indikatora lampiƼa ir iedegta. Vadieties pƝc videokartes rokasgrƗmatas, lai noregulƝtu ekrƗnu sekojoši.

HorizontƗlƗ frekvence
Laiks, kas nepieciešams, lai noskenƝtu vienu lƯniju no labƗs malas
lƯdz kreisajai malai pa horizontƗli, tiek saukts par 'HorizontƗlo ciklu', un horizontƗlajam ciklam pretƝjs skaitlis tiek saukts par 'HorizontƗlo frekvenci'. MƝrvienƯba: kHz
VertikƗlƗ frekvence
LƯdzƯgi fluorescƝjošajai lampai, lai lietotƗjam parƗdƯtu attƝlu, ekrƗnam šis attƝls ir jƗatkƗrto daudzas reizes sekundƝ. ŠƯs atkƗrtošanas biežumu sekundƝ sauc par 'VertikƗlo frekvenci' jeb 'Atsvaidzes intensitƗti'. MƝrvienƯba: Hz
