i have a acer predator moniter with 144 Hz, i was using a dvi d cable and that worked fine for about 2 months. but now when i plug it in that socket where i use to plug it in i get no signal, my pc cant use dvi d for some reason when i put in there it gives me no signal, im thinking about buying a displayport cable but i dont know if i can run it, there is no place on the back where it says ''displayport'' so i dont know if i can run it should i get displayport to dvi d?, and i when i used my dvi d cable i plugged it in the dvi i socket, cause my dvi d socket dosent give me any signal. i can post a picture of the bag of computer if needed
