Předvolené režimy

Pokud je signál z počítače stejný jako jeden z níže uvedených předvolených režimů, nastavení monitoru proběhne automaticky. Pokud se však signál liší, obrazovka může zůstat prázdná, zatímco kontrolka napájení svítí. Nahlédněte do příručky ke grafickém adaptéru počítače a nastavte monitor podle níže uvedených pokynů.

Horizontální frekvence

Čas, který jeden řádek obrazu potřebuje k přeběhnutí mezi levým a pravým okrajem obrazovky, se nazývá horizontální cyklus a jeho převrácená hodnota je horizontální frekvence. Jednotka: kHz

Vertikální frekvence

Jako fluorescenční lampa, obrazovka potřebuje k dosažení stabilního obrazu překreslit obraz několikrát za sekundu. Frekvence tohoto opakování se nazývá vertikální, nebo také obnovovací frekvence. Jednotka: Hz
