Abstract

L'invention concerne un dispositif de commande d'affichage dans lequel l'unité de génération d'image (12) d'un moniteur (1) génère et affiche une image d'affichage dans laquelle les images d'entrée d'une pluralité de PC sont agencées de façon appropriée. Une unité de commande (11) commande la résolution des images qui sont générées par les PC en fournissant des données d'identification d'affichage étendues (EDID), comprenant des informations relatives à la résolution d'affichage d'image, à chacun des PC. Le moniteur (1) est capable de fournir des EDID, qui diffèrent par rapport à la résolution, à une pluralité de PC. Lorsqu'une unité de réception de paramètres (13) reçoit un changement de paramètre, l'unité de commande (11) fournit les EDID, qui correspondent au nouveau réglage, à chacun des PC et amènent chacun des PC à générer une image ayant une résolution qui correspond aux paramètres modifiés. Toutefois, l'unité de commande (11) ne fournit pas d'EDID à un PC qui ne requiert pas de changement de résolution avant ou après une modification de paramètres.
