Does W10 support MST daisy chaining on a Mac?

    I would like try daisy chaining two Dell U2515H monitors (over DP1.2). I know this does not work in OSX but wondered if it did boot camped with Windows 10. I have a late 2012 MacMini and late 2013 13" rMBP. At the moment I am using two mDP cables on my rMBP in OSX. I was going to setup my MacMini as a home PC but as OSX does not support daisy chaining thought I would give W10 a go.

    Does anyone know? Thanks

    yes, this is a software level issue with Mac, windows supports MST.

    Not on the Mini, at least not without an eGPU. I own a 2012 Mini Server with 16GB of RAM (also increasing for the VRAM) - the Mini's built-in Intel HD Graphics 4000 supports DisplayPort v1.1, and the displays require DisplayPort v1.2 for MST. I also own a 15" late-2013 rMBP with dGPU - I can get MST "working" on this, but my success has been limited in part to the model of Dells that I'm using here (P2715Q) - mirroring only, and DP 1.1 on the second display (30Hz).

    Re the Mini -

    It's hardware limitations, not software limitations. Tested Win 8.1 Pro and Win 10 Pro, BootCamp and in VMs.
