This is my gpu http://xfxforce.com/en-gb/products/amd-radeon-r9-200-series/amd-radeon-r9-280x-black-double-dissipation-edition-r9-280x-tdbd

This is the new monitor im getting http://www.ebuyer.com/720853-acer-xf270hu-27-wqhd-ips-monitor-with-freesync-um-hx0ee-001?mkwid=s_dc&pcrid=51482416139&pkw=&pmt=&gclid=Cj0KEQiAguXBBRCE_pbQ5reuq8MBEiQANji2Lf9P7M7jGRpTpokO8XRj4HbFCGfhhPlbJqtJDjUBAOQaAt9l8P8HAQ

Im no wizard when it comes to hardware so Im wondering if I can just use hdmi to get 144hz at 1440p or if I will have to use display port.

Also if the gpu even has display ports as it only looks like dvi and hdmi to me...

The two ports above the HDMI are mini-displayport connectors. They are displayport 1.2 standard -- they are supposed to support 144 at 1440p. -- https://en.wikipedia.org/wiki/DisplayPort#Resolution_and_refresh_frequency_support_for_DisplayPort

so are you saying I should buy the correct cable for them? Or will HDMI support 1440p at 144hz?

I would buy the correct displayport cable. Even if you have an HDMI cable, do you know which standard it supports? The card supports 1.4a version, which I can't tell for sure supports 144hz 1440p ...

Just checked, everything should work at the desired settings with a displayport cable. Thanks for your help
