Gtx 970 displayport

Hi everyone. Does anyone know if the asus strix gtx 970 has a 1.3 displayport and is it better than an hdmi?

Nope, it's 1.2 only. But that's enough for up to 60hz @ 4K, which is equivalent to even HDMI 2.0 (the top HDMI spec at present).

Both are lossless digital connections, so as long as HDMI supports the resolution and refresh rate of your monitor it will provide the identical picture. It's just that DP supports a wider range of resolutions, refresh rates and features.

Asus aren't that specific but Nvidia are. These are standard connections on your card: Dual Link DVI-I, HDMI 2.0, 3x DisplayPort 1.2

Yes, DP 1.3 is better than HDMI 2 but that doesn't help you if card doesn't support it: http://www.planar.com/blog/2014/12/15/displayport-13-vs-hdmi-20/

Displayport 1.2 is capped at 60Hz 2160p and DP 1.3 goes to 120Hz 2160p. But nothing is DisplayPort 1.3 yet, it just got finalized I believe. HDMI 1.4 is capped at 30Hz 2160p and 2.0 ups it to 60Hz 2160p. The 970/980s have DisplayPort 1.2 and HDMI 2.0 (http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-970/specifications), so the max you can do is 60Hz at 2160p.

GTX 970 released before DP 1.3 was finalised so its only got 1.2

Ok. Thanks for all the info people. So would I need to get a high speed hdmi cable then?

all hdmi cables are the same, its a digital connection, i don't think it can go any faster.
