Bonjour,
J'ai récemment installé Ubuntu 20.04 LTS pour le travail, j'ai un écran Asus Asus rog xg32vqr et une carte graphique GTX970.J'utilise l'écran en display port sur Windows sans problème, mais pour Linux impossible il n'envoie pas d'affichage sur l'écran. Je dis bien n'envoie pas et non ne détecte pas car en faisant un xrandr avec le display port (je prépare la commande avec l'écran branché en HDMI et je lance après avoir raccordé) il me met une détection voir ci-dessous :

Je ne suis pas habitué à Linux la solution est peut-être toute simple mais j'ai consulté les sujets sur le forum en général ce sont des problèmes du double affichage ou de passage dvi-displayport etc. donc assez différent en soi.
Merci d'avance pour votre aide 🙂
