So I got a bright shiny new MSI GTX 1080 gaming X. But when I hook it up to my Acer XB280HK thru Display port, it reports no signal. I have an older monitor which I hooked up using DVD. The card works just fine. Searching around I found other people have had issues with display port on the 1000 cards. Seems to be something about DP 1.4 vs 1.2. Nothing has worked. Any thoughts?
