Ho uno schermo esterno al lavoro, che il mio MacBook riconosceva senza problemi. Quando sono arrivato oggi e l'ho collegato, non lo riconoscevo più. È collegato tramite un adattatore Displayport-DVI, a un display HP ZR2440w.
Ho seguito tutti i passaggi nel thread di supporto Apple standard su questo argomento, incluso il ripristino della PRAM usando Opzione + Comando + p + < kbd> r . Ho anche aggiornato da OS X 10.9 a 10.10 sperando che possa essere d'aiuto.
Ecco alcune specifiche:
- MacBook Pro (Retina, 15 pollici, fine 2013).
- Processore: Intel a 2,6 GHz Core i7
- Memoria: 16 GB 1600 MHz DDR3
- Grafica: Intel Iris Pro 1536 MB
Seguendo la risposta Fine del 2011 13 "MacBook Pro non rileva più il monitor esterno su Mavericks , ho anche dato un'occhiata a Color Sync , sotto Dispositivi, Display. C'è solo LCD a colori. stesso profilo sotto Profilo di fabbrica e profilo corrente.
Quando collego il cavo, fa risponde: smette di usare la grafica integrata e usa invece Nvidia. Ma questo è tutto ciò che posso rilevare.
Come posso procedere?
Aggiornamento: gfxCardStatus
Come per l'altra risposta, ho scaricato gfxCardStatus e l'ho impostato solo sulla grafica discreta. Quindi, ha funzionato per un giorno. Oggi, ancora non ha funzionato. Ecco alcune attività di registro per ieri, quando funzionava. Spero che sia sufficiente, non ne capisco abbastanza, ma c'è qualche azione di Thunderbolt in corso:

E qui c'è qualche registro da oggi, quando non funziona. Ho dormito nel Macbook, aperto il coperchio, inserito il cavo dentro e fuori da entrambi gli slot della porta del display.

Set di registri finali : la sera, dopo essersi svegliati, ha funzionato di nuovo per alcuni minuti, ma poi, ricollegandolo, ha smesso di funzionare. Ecco la sessione in cui prima ha funzionato, quindi si è interrotta:
