RE: Inspiron 15 Gaming 7567 HDMI Specs/Does HDMI out support full bandwidth for G-SYNC Dell Gaming Monitor – S2417DG
Well I just got off the line with NVIDIA support and they pretty much said what you said. There is no way HDMI will support passing the full video capabilities that the GTX 1050T i graphics card supports/puts out. It requires a DisplayPort output, and again like you mentioned, it requires it be directly connected to the graphics card. So bottom line, I paid for a graphics card that I cannot fully use. To make things worse within a short time they reconfigured the Inspiron 15 Gaming Laptop to 7677 and it does include a 1 x Thunderbolt™ 3 Port (USB 3.1 Gen 2 Type-C™ with support for 40 Gbps Thunderbolt and DisplayPort). So I now have a $1300 non-gaming laptop. Time to talk with customer support and see if anything can be done.
