Hi, my display port isn't working with my Acer Predator Z35. I have used it before for a long time but just today it stopped working but my monitor works with HDMI. The HDMI however doesn't handle 160hz and so I need the display port. When I go to my monitor controls if I switch it to DP from HDMI then it just stops working. I have tried turning everything off. Unplugging everything and making sure that it's plugged back in tight and none of it works. I would really appreciate it if someone could give me a fix to this which doesn't include anything too technical because I'm not a PC pro and I don't understand many terms.
