Asus Monitor stays in standby after interaction

[NiwaStanley]

I'm trying to narrow down a problem I've been having with my monitors. I have a MSI 980 Ti Lightning graphics card and three Asus VG248QE monitors connected using the display ports. Whenever my computer turns off the monitors to save power, sometimes one, two, or all the monitors don't come back on when I touch my mouse. The power lights on the monitors that won't turn on are orange, and none of the buttons including the power button respond. To fix the problem, I have to unplug the Displayport AND the power cable from the affected monitors until it's off and plugging them back in resolves the issue, but of course it'll occur again if the power management turns them off. Any suggestions would be greatly appreciated. 

Theories:

#1
I was reading about Displayports not being certified and there's a pin 20 that provides power back and forth and I'm not sure if mine isn't certified so that might cause the problem.
The cables I got: https://www.amazon.com/UGREEN-DisplayPort-Plated-Version-Resolution/dp/B00B2HOVK0

tl;dr My graphics card is the problem.

If you have some HDMI cables lying around try those. If those don't work, I really don't know the issue. The only fix I could think of is to go into the Display settings and fiddle around with that.

HDMI doesn't cause any of those problems.
