Q: Macbook Pro crash when connecting a third LCD on Sierra

Greetings,

 

I have 3 LCD 27 inch connected on my MacbookPro for a while now and it work fine in previous OS release.

 

I have 1x LCD connected directly in HDMI, 1x using DVI adapter and 1x using HDMI adapter.

 

After I install Sierra, if I connect 2 LCD it work but as soon as I connect the third LCD it freeze the laptop.  I tried various combinaison of LCDs and the order its connected and it always free the MacBook. I need to then hardreboot the laptop.

 

I want to reeterate that it was working on el capitan and yosemite...

 

I have also tested the same setup on a similar spec'd macbook pro and it freeze also.

 

As anyone have the same issue and/or a solution?

 

My guess is the video card driver is buggy but who knows...

MacBook Pro, macOS Sierra (10.12), null
