This is the only time when Thunderbolt is a real problem. Last but not least, the Target Display mode. The LED Cinema Display 24-inch screen works on all Macs on Mini DisplayPort or Thunderbolt.
The only thing to know is that the sound will come on USB on older models, which is not a problem.
The LED Cinema Display 27 inch screen works on all Macs on Mini DisplayPort or Thunderbolt. The 27-inch Thunderbolt screen only works on a Thunderbolt Mac. Of course, all Thunderbolt machines carry the sound on Mini DisplayPort. It works with all the 2011 or 2012 models.
#WHAT IS THE MAC MINI VIDEO PORT PRO#
The Mini DisplayPort HDMI adapters and the 27 inches Apple Cinema Display screen can not receive sound on this type of machine.įor the sound, you need a MacBook Mid 2010 (GeForce 320M), a MacBook Air 2010 11-inch or 13-inch (Core 2 Duo), a MacBook Pro 2010 13-inch (GeForce 320M), a MacBook Pro 2010 15-inch or 17-inch (GeForce 330M), a Mac mini 2010 (Core 2 Duo), an iMac 2009/2010 21-inch, an iMac 2009/2010 27-inch, or a Mac Pro 2010 (please note that changing the graphic card does not bring the sound). This is a limitation due to the motherboard. On the first generations of Mac equiped with Mini DisplayPort (MacBook Pro 2008/2009, etc), the sound is not transmitted on Mini DisplayPort. Specifically, a Mini DisplayPort adapter runs on a Thunderbolt plug. Technically, the plug is the same and the only difference is that the Thunderbolt connector can carry – in addition to the classic Mini DisplayPort – a Thunderbolt signal, which is a signal PCI-Express (4 lines). Thunderbolt is fully compatible with Mini DisplayPort peripherals. When waking from sleep video is displayed via the Display-Port after about 10 seconds.As this issue os often misunderstood, I will expose the difference ( and also similarities ) between Thunderbolt and Mini DisplayPort.
The problem is not apparent when putting the Mac Mini to sleep, only cold-boot. Once I have output via HDMI and am logged in I am then able to switch to the Display Port input on the monitor and run with display port output. It then boot's to the black screen with Apple logo and takes slightly longer to boot (presumably checking the file system), but there is video. The only option is to press the power button on the Mac Mini for 5 seconds to shut it down. I know there should be output because the LED on the Mac Mini is lit solid at this point. If I cold boot using HDMI, most of the time I get video output, occasionally there is none. Display-Port v1.2 is enabled on the monitor (it makes no difference if it's enabled or disabled). Im using a Dell provided display-port to display-port lead with no adapters, one end is plugged in to the Thunderbolt/Display-Port on the Mac Mini and the other is in the Display-Port on the monitor. Problem = On a cold boot I get no video output via the Display Port.
#WHAT IS THE MAC MINI VIDEO PORT SOFTWARE#
OS = Yosemite 10.10.1 all fully up to date with no software updates available. Computer = Late 2014 Mac Mini 2.8GHz Core i5 with Intel Iris 1536 MB Graphics.
