XPS15 9550 - NVidia G-Sync on External G-Sync Monitor

[BerlinGuy]

Hi all, 

can anyone tell me or point me to a source that will give me clarity on the question if the GTX960M in the XPS15 9550 does support NVidia G-Sync via the USB-C/TB3 Port? Of course I would need an adaptor from USB-C to DP if the Screen only supports DP as Input but the question here is about the G-Sync capability of the XPS15/the GTX960M. 

Thanks in adance

According to nVidia, the minimum GPU for G-sync is the GTX965m.

The notebook mainboard must also support G-sync  -- something I suspect the 9550 does not.
