How is HDMI connected in Inspiron 15 7000 Gaming/065C71

I would like to know what graphics card is being used for HDMI port. I own an older XPS 15 laptop that used nvidia card for HDMI and integrated intel one for Display Port. That was nice as I didn't need to have a working nouveau setup to connect my laptop to a external screen. But this Inspiron model looks to not have any displayport connection and only looks to have a HDMI one. Hence, I would like to know how is it connected to try to know how to use it.

Thanks a lot!
