J'ai un Mac Mini de la fin 2012 qui exécute OS X Mavericks (10.9.5). Lorsque je branche deux écrans sur le Mini (un Thunderbolt, un HDMI), il se configure et fonctionne correctement pendant un certain temps.
Après 1 à 2 heures, ou si je fais quelque chose de graphiquement intensif (lancer un jeu), l'écran HDMI se coupe. Il devient vide et OS X ne reconnaît pas qu'un deuxième écran est connecté. Le redémarrage n'aide pas, mais si je laisse le système éteint pendant un certain temps, il revient parfois. Je n'ai jamais eu de problème avec l'écran connecté au port Thunderbolt.
Le système est dans l'état où il ignore le port HDMI, et j'ai fait le test suivant : en utilisant un câble HDMI Belkin sur un moniteur 1080p avec un port HDMI, je l'ai connecté au port HDMI de la Mini et rien. J'ai pris le même câble, je l'ai connecté à un adaptateur HDMI-Thunderbolt, je l'ai branché au port Thunderbolt et ça marche. Je ne pense pas avoir un problème de câble. Mon hypothèse la plus probable est la chaleur (si je laisse le boîtier éteint pendant un long moment, il recommence à fonctionner) mais tout ce que j'ai essayé pour contrôler la chaleur n'a pas fonctionné.
Je suppose qu'il y a un problème avec la puce graphique ou la logique de l'interface HDMI. Je me demande s'il existe des astuces pour résoudre ce problème, ou s'il existe un autre moyen de connecter un deuxième écran sans recourir à l'USB.
