DisplayPorts ceasing to function sequentially?

[LainVonDark]

Hi,

 

I am having a really strange issue whose cause I am absolutely clueless about. I currently have a Cintiq display connected over DisplayPort to my GTX1070. A couple of days ago, I randomly got a "No Signal" on it, and even after unplugging it and plugging it back in, it still wouldn't come back online. I swapped to the second DP port, and it turned back on again, but the port it was originally connected to still won't detect it.

 

Now, the second port is behaving the same way, and I am down to my last port, and neither of the other two show any sign of working. The tablet won't even get picked up on the nVidia control panel when plugged into one of the first two ports.

 

Thoughts?

 

Thanks

Where did you get the DisplayPort cable from? You may be having this issue: http://monitorinsider.com/displayport/dp_pin20_controversy.html

 

Also, what do you mean by this?:

I got the cable from a store deemed reputable here in Portugal, and I've had no issues with this cable until now, and I've been using it for almost a year. It is, however, a DP to miniDP cable, as mentioned on the topic you posted, which worries me somewhat.

 

Unfortunately, I have no other DP devices I can use to test if I fried something or not.

 

And what I meant was that the display won't show up on the nVidia control panel, unless it's plugged into this last, and currently, only working, DP.
