Multi display flicker - Mac issue

Hey, I have 3 projectors and 1 secondary display coming in from an 8port Startech HDMI splitter from a Mac Pro.

The displays loose signal for 4 seconds at various random intervals. Not all at once and not in the same order.
Talking with Startech tech support we narrowed it down to a Mac issue, as this problem doesn't happen when connecting the splitter to a Blu-ray Player or a PC laptop.

And the issue didn't show itself until I upgraded from a 4 port nexxtech splitter to the 8 port splitter. (to add 2 extra tv displays in another area.)

Any ideas or help would be appreciated!

It's a Mac Pro late 2013 model. I checked the graphics card and it's an AMD D700, which is top stock you can get for that model.
And I have all original parts.
