I'Be posted this on macrumors. But thought I would share.
Its working!!!! I'm excited. Just what I was looking for.


And a mono price mini display port female coupler.
I'm super happy.
TO review,
I have the Google usb-c to Display port, hooked to a Mini displayport to Displayport Female adapter, to a mono price female coupler. I close the lid and use insomnia X. Works perfectly.
