I’m doing a fresh windows install since my current one is quite old. I’ll report back if this fixes it.

Newest drivers and the new firmware didn't resolve this issue. Here is a new video I shot at 60 fps to get as much data as possible. the TV appears to go black from bottom to top and then recovers. In real time it happens so fast that it looks like a flash.

In case anybody was wondering.. I fixed this issue by disabling internet to my tv... So no wifi connection or wired connection (which is what I was using)... It's a very strange bug, and I reported it to lg.

I had to register here just to let other know that this actually worked for me. Not sure how/why the internet connection could be causing this kind of problem, but it seems to have fixed it for me, at least for now. I tested it for about 1.5hrs and didn't experience any of the black frames. Previously I would receive at least 1 black frame at least every 30mins or so. For the record, I was using a wired connection.

Hi guys,

I know this was a few months ago but just wanted to check up on this. For those who disconnected their C9 from the internet to resolve their Gsync black flicker issue, now that its a few months later has that still resolved the issue or has it come back since? I'm currently testing a C9 using this resolution myself with positive results but I have been given some other possible fixes including disabling the advertising cookies and disabling the Auto Power Sync option in hdmi settings. apparently people are reporting you can keep the TV connected to the internet with these options disabled but further testing is required.

Thank you for any help you can provide
Cheers
