Abstract

L'invention concerne un procédé de commutation de version HDMI. Le procédé comprend les opérations suivantes : un dispositif d'affichage détecte, après réception d'un signal vidéo entré par un dispositif d'entrée externe au moyen d'une HDMI, si un paramètre de signal du signal vidéo correspond à celui qui se trouve dans des informations EDID d'une version HDMI configurée; si le paramètre de signal du signal vidéo ne correspond pas à celui qui se trouve dans les informations EDID de la version HDMI configurée, le dispositif d'affichage commute la version HDMI. L'invention concerne également un dispositif d'affichage. Ainsi, la détection d'une anomalie d'un signal vidéo et une commutation de version HDMI peuvent être réalisées par le dispositif d'affichage, et un utilisateur n'a pas besoin de commuter une version HDMI au moyen d'une opération manuelle après découverte d'un affichage d'image anormal, de telle sorte que l'expérience d'utilisateur peut être efficacement améliorée.
