It’s an adapter 😉
Depends on the source, What GPU will you use.
But in general, HDR is supported Gsync is not.
Remember to use a certified HDMI cable with the adapter like the CAC-1372

1080 Ti is Pascal generation. It doesn’t support DSC so you’ll be limited to DisplayPort 1.4 non-DSC modes (4:4:4 or chroma sub sampling modes 4:2:2 or 4:2:0).
Without DSC, 4K120 is not possible with DisplayPort 1.4 unless you reduce the pixel clock from HDMI’s 1188MHz down to under 1080MHz for 4:4:4 8bpc (such as CVT-RB2’s 1076 MHz) or you use 4:2:2 10bpc (which may be necessary if HDR requires 10bpc).
4K120 4:2:0 8bpc can work with HDMI 2.0 signalling.
I think the TV has a method to show the input signal type.

TM = TMDS = HDMI 2.0
4L10 = 4 lanes of 10Gbps each = HDMI 2.1 (but not the highest speed 4L12)
