Exposing Tile Properties for MST 4K monitors running dp 1.2

Dear Nvidia,

I installed fedora 23 which sports Xorg 1.18 and randr 1.5. According to the gnome desktop mailing list, the MST tiling issue I have on my 4K monitor should be delt with, but after e-mailing them the output of xrandr --prop, they tell me the Nvidia x server is not “exposing tile properties”. Thus the question is… is nvidia planning on exposing those tile properties? I hope this is on the road map.

Thanks. Steve.
