Re: Random screen flashing gsync compatibility LG C9

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.

Re: is the lack of variable overdrive of G-Sync compatible monitor noticeable? (LG 27gl850)

Oled is even faster than tn, so I would think the lack of overdrive isn't a big deal on the lg oleds that are gsync compatible.

Re: Random screen flashing gsync compatibility LG C9

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. https://www.youtube.com/watch?v=013Mtsn6iZ...

Re: Random screen flashing gsync compatibility LG C9

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

Re: Random screen flashing gsync compatibility LG C9

Your guess is as good as mine :-/ I could have a tcon board failure... Check out this video from linus. The relevant info starts at 2:20, but the entire thing is worth a watch. LG is sending out a tech tomorrow that i've already briefed on the situation. https://www.youtube.com/watch?v=Um0PFoB-Ls4&...

Re: Random screen flashing gsync compatibility LG C9

So i'm not the only person with this issue. Now, im not sure how widespread this is. Other people with c9's say they don't have an issue. Could it possibly be an issue with the panel itself? The uniformity on my panel is very good and i'm afraid of exchanging this for another c9, not fixing the fla...

Re: Random screen flashing gsync compatibility LG C9

If it corresponds with a stutter, that could mean the driver is not disengaging VRR mode when the frame time gets too high, and as a result the pixels undergo a "whiteout" due to not getting refreshed in time. So it could be a driver issue. Yeah, I’m not sure if I t does or not. I’m not feeling a s...

Re: Random screen flashing gsync compatibility LG C9

Okay, so I unplugged the hdmi cable going to my receiver and I’m now just using earc and the Dolby atmos app for the surround audio. It seems to have helped, but now I just get it much less frequently. I believe it’s corresponding with a stutter. I’m not the only person with this yo yo experience th...

Re: Random screen flashing gsync compatibility LG C9

Hmmm. Troubleshooting Have you upgraded to the latest LG c9 firmware and latest NVIDIA drivers? Or it only started to happen with the latest drivers? Technical Explanation For background knowledge; I've seen VRR flashing happen with driver bugs or display bugs which causes: (1) Refresh rate range t...
