Ok, well the confusion I had was from watching the videos on the G750 and hearing them talk about the port as being both Mini HDMI and Thunderbolt. So I thought that this was a new design that I had missed. Thanks for clearing that up!
I'm looking into my buddy using a Thunderbolt cable to a Sonnet Echo Express and then using a ViDock 4++ plugged into that with a EVGA GTX 770 Super clocked installed into that so he can run 3 large monitors on his desk and use his G750 without trying to run 3 large monitors from the GTX860m. All in all it's as much as building a good gamin desktop rig, but he can't break from having a laptop.
