Tengo una pantalla externa en el trabajo, que mi MacBook solía reconocer sin problemas. Cuando vine hoy y lo conecté, ya no lo reconocía. Se conecta mediante un adaptador Displayport a DVI a una pantalla HP ZR2440w.
Seguí todos los pasos en el hilo estándar de soporte de Apple sobre este tema, incluido el restablecimiento de PRAM utilizando la Opción + Comando + p + < kbd> r . También actualicé de OS X 10.9 a 10.10 con la esperanza de que pueda ayudar.
Aquí hay algunas especificaciones:
- MacBook Pro (Retina, 15 pulgadas, finales de 2013).
- Procesador: 2.6 GHz Intel Core i7
- Memoria: 16 GB 1600 MHz DDR3
- Gráficos: Intel Iris Pro 1536 MB
Siguiendo la respuesta A finales de 2011 13 "MacBook Pro ya no detecta el monitor externo en Mavericks , también eché un vistazo a Color Sync , bajo Dispositivos, Pantallas. Sólo hay LCD a color. Enumera los mismo perfil en Perfil de fábrica y perfil actual.
Cuando enchufo el cable, sí responde: deja de usar los gráficos integrados y usa el Nvidia en su lugar. Pero eso es todo lo que puedo detectar.
¿Cómo puedo proceder?
Actualización: gfxCardStatus
Según la otra respuesta, descargué gfxCardStatus y lo configuré solo para gráficos discretos. Entonces, estuvo trabajando por un día. Hoy, de nuevo no funcionó. Aquí hay alguna actividad de registro para ayer, cuando estaba funcionando. Espero que sea suficiente, no entiendo lo suficiente, pero hay algo de acción de Thunderbolt en marcha:

Conjunto final de registros : En la noche, después de despertarse, funcionó nuevamente durante unos minutos, pero luego, lo enchufé y entré, y dejó de funcionar. Aquí está la sesión donde primero funcionó y luego se detuvo:
