Aug 12, 2014 7:21 AM in response to 13kotby Grant Bennet-Alder,The new late 2013 Mac Pro supports up to six screens directly.
¿Why are you bothering with Tripe-head to go?

Aug 12, 2014 11:03 AM in response to Grant Bennet-Alderby 13kot,Because direct connection significantly reduces performance.
It can be seen that the card can not cope with 6 video streams.
And I wanted to experiment with reliable video cards.
Mac Pro does not support 2 TripleHead?
And Black screen and system hang occurred when I connected to my MBP Retina 2 triple head card.
Maybe there are some restrictions on the system Mac os X?

Aug 13, 2014 8:24 AM in response to 13kotby Grant Bennet-Alder,I disagree that your problem has anything to do with the built-in graphics cards falling short. In my opinion, you are trying to move more data to the six screens than can be transferred from the number of sources you have, in the time you want.
Try this experiment:
Set each of the displays to mirrored (the same data on each screen). Now play ONE movie onto all six screens. If you get drop-outs, the display card is defective (or, as you assert, inadequate.)
I believe your other experiment (with six different data streams to six different displays) is I/O bound. If you get drop-outs you need more drives in more different enclosures to provide enough concurrent data for the displays.
Another experiment to try is to run two displays. Then try three. Then four, and so on. If you study where it fails and analyze how much data is needed to support each stream, I believe you will find that the amount of data required is more than can be produced by one or two ordinary drive or SSDs.
A single ordinary rotating drive can produce a single burst at about 125 MBytes/sec, not sustainable. To supply moving pictures to six displays takes far more data than that.
A third experiment is to reduce the resolution on each display to the lowest it can achieve, and play those smaller windows. Perhaps it can play six half-sized movies.

Jan 18, 2015 10:38 AM in response to 13kotby cowboya,I´ve had two Tripplehead2gos running on two generations of Macpros pushing 6 x vga screens or 2 x 3072x 768.
You need to set them up singularly, then only keep one usb plugged when booting with two, the other drawing external power.

Feb 9, 2015 12:04 PM in response to 13kotby domedavid,13kot, did you ever resolve this? i'm guessing the issue is needing to use active tunderbolt to DVI/DP adapters. see here: Mac Pro (Late 2013): Using multiple displays - Apple Support
i'm asking because i want to do the same thing. i have one th2go (DP version) running but want to add another. Matrox says they don't support two boxes on a Mac but like @cowboya i've been running two Digital Editions to push six VGA (xga res).
feedback appreciated!
thanks.

Oct 19, 2015 12:09 PM in response to domedavidby clixfrommunich,Just saw this thread :-D bit late..but: Yes, It is possible! We made a proof of functionality with four (4) Matrox Trippleheads2Go and 12 (twelve) projektors running at 768x1024 resolution with MacPro 2013 and D700 included. We figured that out for 3d-Videomapping-Purposes and solved the problem. There is a tricky part while connecting the TH2GO`s AND YOU HAVE TO UNINSTALL Powerdesk ;-) thats the same trickey part as if you`re on Windows-Machines. Wish you a nice testing, it takes us a complete Night to figure that out but it works at last with no dropouts, i think it is possible to connect one TH2GO per MDP (Thunderbolt-Port)...that makes a summary of 18 Projectors, but you`ll lose a Control (Main-) Monitor, but we`ve never tested that situation. A workaround could be to use VNC or something similar ;-) Happy testing! XD
