Il display esterno acquisisce in modo casuale e perde il segnale sotto Mavericks 10.9.4

Sto tentando di utilizzare uno schermo esterno Planar PXL2790MW con il mio iMac 11,3 (27,93 GHz 27 pollici) collegato tramite un cavo da Mini DisplayPort a DisplayPort.

Il display funziona a intermittenza: in momenti casuali, acquisisce il segnale dal computer e poi lo rilascia di nuovo dopo ovunque da dieci minuti a mezz'ora. Non segnalerà alcun segnale per diversi lassi di tempo prima di riattivarlo brevemente. Riavviare il computer e accendere e spegnere il monitor (in qualsiasi ordine) sembra non fare alcuna differenza se il segnale viene inviato o meno. Sembra abbastanza casuale.

La stessa cosa accade sia in BootCamp (Win7) che in OSX (10.9.4) Quando il display ha un segnale, funziona perfettamente. Durante uno degli intervalli in cui stava funzionando, ho provato a spostare il cavo energicamente, includendo anche le porte, per vedere se questo è il problema; non sembrava fare la differenza.

Ho provato a zappare la PRAM e resettare SMC, senza alcun effetto. Ho provato a rilevare il display in Windows quando si spegne, anche senza alcun effetto.

Modifica: accludo il log della console per uno di questi eventi (uno particolarmente breve, il monitor è solitamente lucido per molti minuti). Il display esterno, come possiamo vedere, è 0x3f003d. Si accende, quindi alla fine passa allo stato offline, senza alcun motivo che possa discernere.

Risoluzione dei problemi

  • Prova un altro cavo

  • Controlla il log della console per scoprire il motivo

  • Disattiva la commutazione della grafica

  • Apri l'utility ColorSync (nella cartella Utility) per vedere se lo schermo è lì e quale driver è selezionato.

UPDATE:

Dal registro della console 

Found 111 modes for display 0x003f003d [111, 0]

Il sistema ha problemi a selezionare la modalità da utilizzare.

Apri l'utility ColorSync e imposta il profilo corrente sullo stesso profilo di Factory.
