Issue with Google Chrome and my Acer Z35P began just after "managed by your"

[Andrew379]

I have an Acer Predator Z35P monitor with Gsync and 2 GTX1070 founders in SLI. A weird and very annoying issue has just began happening since Avast started controlling Chrome with "managed by your organization". When I open any video in full screen mode in Chrome my monitor turns to static and retracts to the top of the screen, audio still plays and my second monitor still works fine. I have to unplug the monitor and plug it back in to get the screen to come back on. This issue does not happen in FireFox or in Internet Explorer it only happens in Chrome. FYI I have restored my chrome and removed all addons except Avast and the issue is still present, I have tried turning Gsync off, I have tried setting the monitor to other refresh rates.

UPDATE PROBLEM SOLVED AND EXPLAINED BELOW
The problem was due to Chrome using my hardware to accelerate features such as video. I am not sure why this has suddenly become a problem but if anyone else is experiencing this the fix is very simple.
1) Open settings in Chrome (the three dots in the upper right hand corner).
2) Open advanced
3) Open system
4) Turn off hardware acceleration and shut Chrome down completely and restart it

NOTE: if this does not solve the problem you may need to restart your computer to make the changes take effect.

Regarding Avast & Malwarebytes, see: https://forums.malwarebytes.com/topic/200324-exclusions-for-avast-users/

[Andrew379]

I completely uninstalled Malwarebytes, shut the computer down and then rebooted. When I open Google Chrome and try to go to full screen the problem still exists, the screen turns to static and it squeezes itself into into the top of the screen.

[Asyn]

So, does it work if you disable Avast..?

[Andrew379]

I did not know there was a way to disable Avast without uninstalling it which I guess I could do but all of my passwords are saved through Avast and I would not want to lose them also I would have to open Chrome without any virus protection.

[Asyn]

Well, it would be good to know if your issue is indeed related to Avast (and if so, we can dig deeper).

[Andrew379]

I seem to have fixed my issue which was video card related and I will post how I fixed it in the OP in case anyone else has a similar issue.

Thanks for the feedback.
