Added a 3rd 1080 monitor, suddenly videos are stuttering, low GPU usage

[Shikibara]

So I just bought a 3rd monitor that is 1920x1080 using HDMI. I am also using a primary monitor that is 2560x1440 using DP, and a secondary monitor that is 1280x1024 using DVI to VGA. Driving this setup is a pair of 1070ti in SLI (one is FTW, other is something else, but both by EVGA. They are different because my 980ti SLI Setup died and they sent these instead.).

When I plugged the monitor in, I suddenly started experiencing video stutter on Netflix and Amazon Videos. I disabled SLI, swapped the port the HDMI was in, reset the computer, changed the monitor that the video was playing on, and reinstalled the drivers, all to no avail. Upon unplugging the monitor from the HDMI port the issue immediately resolves itself. I would imagine that a single 1070 ti at the very least would be able to support running these three monitors with no background programs running and just watching a simple video, but even at lower video quality, the stuttering persists.

I'm monitoring my GPU load using Open Hardware Monitor, and neither unit is seeing loads over 10%. I haven't tried gaming yet, but this is still concerning.

I don't think there is any other part of the computer that is creating a bottleneck, as these are my specs.

CPU: 5960x
RAM: 32GB
MoBo: Asus Rapage V Extreme
OS and primary programs are on an SSD
Gigabit internet plugged in directly

One thing I am noticing that I just checked while writing this, YouTube has no stuttering issues, even when the video is rendered at 4k, however when I watch the only paid for movie I have through Google on YouTube (Warcraft), that does stutter when all 3 monitors are plugged in.

So I'm currently at a loss. Basic YouTube content seems to run fine, but when I dare to run a video that is from Netflix, Amazon, Vudu, or a movie movie from YouTube, it stutters like a 3rd grader giving their first public speech. I'll ask around on other forums as well to see if anyone has a thought about what might be up, but hopefully I can get this resolved sooner than later

I wish I could help you, this is a weird issue.  Ok we know your hardware is ok.  So my suggestion is boot into safe mode and run DDU "Display Driver Uninstaller" then boot back up to normal mode and install the latest nvidia 417.xx drivers.  Then let us know what happens.  good luck

Tried it but no luck  still getting stuttering. I just wonder why normal YouTube videos are unaffected but paid for stuff on YouTube is. If it was all of YouTube being fine, I would be led to believe that it was something up with other sites, but the only connection I'm seeing is creator made content vs. major production studios. Maybe Hollywood has a thing against people who use 3 monitors? XD

Ya dude, Ive never heard of your situation before.  Honestly IMO, it is uncle billy's fault.  What OS and build are you using.  The 1809 messed things up for people like you with dual monitor or a monitor and a tv.  Ok try this.....  The monitor you just added and your main display and disconnect the 1280 resolution monitor and let me know what happens.

Tired that, and stuttering decreased some, but not completely. Side note, no games stutter at all. I've tried simple games and more taxing games and from what I can tell, there is no real dip in performance, let alone stutter.

Oh, this is interesting. I just remembered Netflix has a Win10 store app, so for the hell of it, I installed that on the computer and it works flawlessly. Stuttering persists on all browsers, which is just baffling.
