Ho un Mac Mini di fine 2012 con OS X Mavericks (10.9.5). Quando collego due display al Mini (un Thunderbolt, un HDMI) configurerà e funzionerà correttamente per un po 'di tempo.
Dopo 1-2 ore, o se faccio qualcosa di intensivo dal punto di vista grafico (avvio di un gioco), il display HDMI si spegnerà. Diventa vuoto e OS X non riconosce che è collegato un secondo display. Il riavvio non aiuta, anche se lascio il sistema per un po ', a volte tornerà. Non ho mai avuto problemi con lo schermo collegato alla porta Thunderbolt.
Il sistema si trova nello stato in cui ignora la porta HDMI e ho eseguito il seguente test: utilizzando un cavo HDMI Belkin su un monitor 1080p con una porta HDMI, l'ho collegato alla porta HDMI della Mini e nulla. Ho preso lo stesso cavo, l'ho collegato a un adattatore HDMI-Thunderbolt, l'ho collegato alla porta Thunderbolt e arriva subito. Non penso di avere problemi con il cavo. La mia ipotesi migliore è il calore (se lascio la scatola per un po 'di tempo riprende a funzionare) ma tutto ciò che ho provato a controllare il calore non ha funzionato.
Suppongo che ci sia qualcosa che non va nel chip grafico o nella logica dell'interfaccia HDMI. Mi chiedo se ci sono trucchi per risolvere questo problema, o se c'è un altro modo per collegare un secondo display senza ricorrere a USB.
