P2715Q, 15 R2, which cable should I use?

Question

I have an Alienware 15 R2 with an nvidia GTX 970 M and I want to connect it to a Dell P2715Q.

In order to get 4K at 60 hz, which cable / output / input should I use?

I can output from HDMI port or Thunderbolt port. And the monitor has Displayport in, miniDP in and HDMI,

It seems like certain cables promise different bandwidth.

What would be the best option for me? Thunderbolt - Displayport? USB-C?

Any help would be greatly appreciated

The mDP to DP cable provided with the P2715Q might fit the TB3 port. So I would test the hardware setup like this =
15-R2 TB3 out --> P2715Q mDP to DP cable --> P2715Q DP in 3840x2160 30Hz/60Hz

If you have an HDMI to HDMI cable on hand to see if it works =
15-R2 HDMI out --> HDMI to HDMI cable --> P2715Q HDMI in 1920x1200 60Hz
