But getting the right setup done for the cables is very important in order to make sure this works properly.

HDMI is a great way to transfer your display from a computer to a second monitor or TV and from consoles to your TV and more.

Changing Display Settings to Required Settings.

What is HDMI and choosing the right cable?.

This has been my recent experience with external displays on the MacPro (late 2013 trashcan). 2 x Tripple Head 2Go + 2 x VGA adaptors + 1 x DVI connector + 1 x HDMI as part of beta testing new software. I am currently testing a set up with a MacPro that has ten displays connected. I can also continue to add displays using the remaining 4 thunderbolt ports - except for the limitation issue with passive digital adaptors - which is a pain.

I can use them both simultaneously through two Thunderbolt ports. I do not have any active miniDP or Thunderbolt adaptors except for 2 x Matrox Tripple Head 2Go DP edition and these work well once the resolutions have been set-up for them. I have tried what appears to be a dual link active HDMI connector (one that has a USB as well as HDMI) to run an external monitor and this cable works, however it still does not allow me to add two more passive DVI adaptors, I can still only get two of the three displays working with it. The Apple Mac Pro external display specification suggests it is only possible to use 1 x passive digital adaptor when using the HDMI connection or 2 x passive digital adaptors through the thunderbolt 2 ports. Using active dual link digital connectors.Īs soon as I try to use 2 x passive digital display adaptors (minDP to DVI) from the Thunderbolt ports I can only get 1 + the HDMI output operating at the same time. There are a number of work arounds and these include using a Matrox Tripple Head 2Go. And only 1 x in conjunction with the HDMI port because the HDMI port shares a bus with the two bottom thunderbolt ports on the machine. However, the specification suggests up to six active adaptors can be used simultaneously. It indicates that only two passive (single link) digital display adaptors can be used at one time. If you look at the Mac Pro (2013) external display specification from Apple. The problem is likely a Mac Pro external display limitation.
