BenQ XL2411P not outputting DisplayPort?

[bobjeffery911]

So I had a freind come over reacentley and he brought his Xbox One. We plugged it in to the monitor HDMI port it was fine until I wanted to play PC again and it wouldn’t read my DisplayPort. I tryed updating drivers and it didn’t work. For reference the monitor: Works fine with HDMI, my GPU is a GTX 1070 and when I tryed using a different monitor with the same display port on the card it worked. So any help would be appreciated. Many Thanks
