Second Monitor won't display

[BLITZKREIG99]

So i noticed that my second tv that i'm using as a monitor wont properly display anything. when i leave it go the screen will go black and then occasionally show my picture but it will show all blurry. I'm using a hdmi to displayport adapter on my GTX 1080. Any help would be greatly appreciated.
The system
Nvidia gtx 1080
amd fx 8320
Sabretooth 990 fx

Why are you using a DisplayPort adapter?

i only have one hdmi port which is on the main tv. the other three are displayport.
