DisplayPort, sonst hast du kein G-Sync.

HDMI (up to 1.4) is not capable of transferring so much data, with HDMI a maximum of 60fps is possible at 1080p, for higher resolutions the frame rate is simply reduced (e.g. 25-30fps at 4K, depending on the device and compression).
HDMI 1.4 achieves 8.16Gbit/s, previous HDMI standards even less (1.2 -> 3.96Gbit/s), so it also depends on the cable, what your devices achieve.
For everything above 1080p or above 60Hz, a DVI-D DualLink (double DVI line in one cable, 16.32 Gbit/s) is strongly recommended, which allows 144Hz at 1080p OR up to 2560*1600 with 60Hz.
If this is still not enough (like with this monitor) there is only DisplayPort left, the current version (1.3) manages 25.92 GBit/s. More (or faster) is currently not available on the consumer market.
The new version of HDMI (2.0a, since April 2015) is not yet widespread on the consumer market, but this standard also lags behind DVI-D DualLink with "only" 14.4 Gbit/s.
I think that if you want to spend almost CHF 850 on a monitor, you won't want to settle for the few frames that are possible via HDMI, so I strongly advise you to use DisplayPort, or to invest your money better. The HDMI interface is only useful here to connect your console to this monitor, for example, because it can't generate and output that many frames, but if you're gaming with a console, you'll probably want to make yourself comfortable on your couch, and gamble on the TV.
Others who are toying with this monitor should first remember that your GPU must first calculate the 165 frames so that you can really enjoy your monitor. At this resolution, this is a mammoth task that not every graphics card can handle.
The 980Ti is certainly up to the task.
That's why I only have 1080p @144Hz, because I don't have my own AKW in the basement and my golden donkey is on holiday at the moment.

For information; display port to HDMI is the cheaper variant (cable from 20 CHF) The reverse conversion is more complex and requires a different cable. So you can't just take the cheaper one and connect it the other way round. HDMI to Display Poer requires e.g. Digitec Product Art-Nr 6082591

The statement is not true
A) DisplayPort (LVDS) and HDMI (TMDS) are not electrically compatible, but DisplayPort can emulate HDMI, vice versa probably not. (DVI and HDMI, on the other hand, are electrically compatible).
B) HDMI has the smaller bandwidth, here are the corresponding ASUS specifications
1) Refresh Rate
DisplayPort: 2560x1440(up to 165Hz)
HDMI: 2560x1440(60Hz)
2) Signal Frequency
DisplayPort 34~209KHz(H)/30~165Hz(V)
HDMI: 30~140KHz(H)/24~60Hz(V)

Displayport
Hello Dadasmemo
If you have the choice of Hdmi to Hdmi or Displayport to Displayport it doesn't matter which connector you use. It shouldn't even make a difference if you go from Displayport to Hdmi, because Displayport's strength is simply to work with other connectors. So there won't be any latency or picture errors anyway.
