Q: Unable to daisy-chain two MST monitors

Dear Apple Support,

 

I have a Retina Macbook Pro (2015 with ForceTouch) and despite supporting MST (as stated here) I am unable to daisy chain two modern Dell monitors. It just mirrors the screen to the daisy-chained monitor.

 

How can this be fixed?

Thank you in advance for your support.

 

Frédéric

MacBook Pro with Retina display, OS X Yosemite (10.10.5)

    Unfortunately this doesn't seem to be fixable, yet. You could run windows using bootcamp, then it will work. Indeed even though OS X supports MST, it doesn't support daisy chaining. It only supports daisy chaining when you connect a thunderbolt display (everybody would cry: evil, if Microsoft did something like this).

     

    I've created a post where I keep track of all topics I could find about this issue here:

     

    MST Support but no support for daisy chaining?
