Estoy tratando de usar un Plano de PXL2790MW pantalla externa con mi iMac 11,3 (2.93 GHz 27 pulgadas) conectados por una Mini DisplayPort a DisplayPort cable.
La pantalla funciona de forma intermitente: a veces al azar, va a adquirir la señal desde el ordenador y, a continuación, colóquelo de nuevo después de que en cualquier lugar de diez minutos a media hora. Se reporta ninguna señal durante diversos períodos de tiempo brevemente antes de volver a encenderlo. Reiniciar el equipo y girar el monitor encendido y apagado (en cualquier orden) parece hacer ninguna diferencia si o no, la señal que se envía. Parece bastante aleatorio.
La misma cosa sucede tanto en BootCamp (Win7) y OSX (10.9.4) Cuando la pantalla no tiene señal, funciona perfectamente. Durante uno de los intervalos en los que estaba trabajando, yo traté de mover el cable vigorosamente sobre incluidas en los puertos, a ver si ese es el problema; que no parece hacer una diferencia.
He intentado restablecer el COCHECITO y la de restablecer el SMC, a ningún efecto. He tratado de detección de la pantalla en Windows cuando se apaga, también a ningún efecto.
Edit: añado el registro de la Consola para uno de estos eventos (particularmente breve, el monitor es generalmente lúcido durante muchos minutos). La pantalla externa, como podemos ver, es 0x3f003d. Se trata, entonces, finalmente, el estado de cambios en offline, sin razón que puedo discernir.
