Dvi-d cable not working but hdmi functioning

[Huakka]

So I recently just bought a new monitor for my pc since my old one was kinda trash, and it works like a charm, with HDMI that is. The monitor itself is supposed to be 144hz but i cant do that with an hdmi and my GPU doesnt have a displayport thing so i thought "Hey! I'll just buy myself a dvi-d cable, work just fine!" but.... When I plugged the the dvi-d cable into my gpu and my monitor it was like a mini war had just started and random colors started flashing my background was jittering and getting distored and junk, it was spooky. Then i plugged in my hdmi cable and it was as if nothing even happened.

I have an amd hd 7870 and my monitor is this http://www.newegg.com/Product/Product.aspx?Item=9SIA0ZW50M9169&ignorebbr=1&nm_mc=KNC-GoogleMKP-PC&cm_mmc=KNC-GoogleMKP-PC-_-pla-_-Monitors+-+LCD+Flat+Panel-_-9SIA0ZW50M9169&gclid=Cj0KEQiAy53DBRCo4en29Zvcla0BEiQAVIDcc9MM1bRYQj4hedJqaG3h5iREv4bcoExB1mGPVjgn8FkaAocd8P8HAQ&gclsrc=aw.ds

Double check if the dvi cable you have is single link or dual link.
