MacPro 6,1 and Displayport MST DaisyChaining? Any Successes?

has anyone had success using MST DisplayPort Daisy chaining.

I know that MST allows me to connect to a sharp PN-k321 in 60HZ. I have been successful with that.

But i want to utilize the DaisyChain feature of Displayport 1.2 MST.

This allows you to connect up to 4 1080p displays to either a hub or daisy chained through the Displayport out feature. If you enable MST on the displays the feature does not work.

I am using samsung LFD Displays.


-Thanks
