I decided I wanted to get double monitors so I had extra screen space to things while streaming, gaming etc. I'm using a GTX 1080 and it only has 1 HDMI port so that's plugged into my main monitor. I purchased this display port > HDMI lead for my second monitor https://www.amazon.co.uk/gp/product/B017Q8ZX1O/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 and I can't get my PC to detect the second monitor. Any help would be great, thanks.
