I have a monitor, Acer GN246HL, which can reach 144hz according to the eBay listing. However, the HDMI port won't allow for 144hz so I will have to use a DVI cable instead but my PC only has a DVI in port, not a DVI out port. I don't really know what I'm supposed to do, I'm not particularly literate when it comes to more than basic tech and I've been told by one of my friends that a Displayport to DVI cable won't give me 144hz.
