stuttering Screen Stuttering in Dual Display Setup

[John Liu]

Here's my rig:

EVGA GTX 1070 SC

Core i7 6700 water cooled

16 GB DDR4 RAM

EVO 850 250G SSD

2 HDDs

Cooler Master v650 gold Power Supply

Display 1: 3440x1440 Ultrawide @ 60Hz via Display Port

Display 2: 2560x1440 @ 60Hz via HDMI

Windows 10

 

And here's my problem:

I been using this rig for gaming for 2 year and never had problems like this, and recently when I was playing game, it just suddenly started to stutter exactly every second, like clockwork, I ran some tests and found out it only happens when I stream video online on either display, with Netflix being the most problematic, and youtube being barely noticeable. Does it have anything to do with the HDCP compatibility? Now I ruled out some of the possibilities: checked the heat, replaced thermal paste, dusted the rig, swapped cables and ports on all the ends, updated windows and Nvidia driver. I think this particular case is not a hardware problem, and I really want to avoid reinstall windows or go back to windows 7 or 8, what else do I have?

Try rolling back to an older driver, and checking to make sure that your display cables are good.

I had the same issue, and when I disabled freesync on my monitor it was fine.

P.s.: i have amd gpu, not nvidia like you
