Je viens d'acheter un téléviseur/moniteur et lorsqu'il est connecté à mon ordinateur portable par la sortie DP, rien ne se passe. Il affiche seulement un journal disant "Il n'y a pas de signal provenant de votre ordinateur". Il en va de même pour la sortie HDMI.
Maybe it is a problem with drivers. I do not know. I wish somebody could help. Thanks.
I attach the following logs:
