3-2 Tableau des modes de signal standard

Le moniteur LCD possède une résolution optimale, garante de la meilleure qualité visuelle en fonction de la taille de l'écran, et ce en raison des caractéristiques de l'écran, au contraire d'un moniteur à tube cathodique.

La qualité visuelle sera dès lors dégradée si la résolution choisie n'est pas optimale pour la taille de l'écran. Il est recommandé de régler la résolution sur une valeur optimale pour l'appareil.

Si le signal provenant du PC équivaut à l'un des modes de signal standard suivants, l'écran se règle automatiquement. Toutefois, si le signal n'est pas l'un des modes suivants, il se peut que l'écran soit vierge ou que seule la LED de mise sous tension soit allumée. Configurez donc les réglages comme suit, en vous reportant à la documentation de la carte graphique.

Fréquence horizontale

Le temps requis pour balayer une ligne de l'extrême gauche de l'écran jusqu'à l'extrême droite est baptisé « cycle horizontal ». La réciproque du cycle horizontal est la fréquence horizontale. La fréquence horizontale s'exprime en kHz.

Fréquence verticale

Pour que l'œil humain puisse percevoir une image, l'écran doit afficher la même image des dizaines de fois par seconde. C'est ce qu'on appelle la fréquence verticale. La fréquence verticale s'exprime en Hz.
