Réponses Acer

Pourquoi le message "No Signal" est-il affiché à l'écran?

Un message «Pas de signal» indique que votre moniteur ne reçoit pas de signal vidéo valide. Cela peut se produire pour plusieurs raisons. Pour vous aider à résoudre le problème, procédez comme suit:

Assurez-vous que le bon type de câble vidéo est correctement connecté à la bonne source vidéo.
Vérifiez que votre source vidéo est allumée et fonctionne correctement.
Essayez un autre câble vidéo si vous en avez un.
Connectez le moniteur à une autre sortie vidéo de l'ordinateur, le cas échéant.
Réinitialisez les paramètres par défaut de votre BIOS.
Testez le moniteur en le connectant à un autre ordinateur.

Si le moniteur affiche toujours un message Pas de signal, veuillez contacter l'assistance Acer.
