Hi, LG49NANO866 Games may flicker when G-sync is enabled. Is there any way to reduce or remove Flickering with G-sync enabled? If so, how can I do it exactly?
I’m using my 49Nana866 tv 4k 120hz 4.2.0 8 bit.
I noticed that 4K and 1440p doing flickering at 120hz. But when I get 4k 60hz, the flickering doesn’t happen when g-sync is active. Frankly, I don’t know what to do. MY LG Firmware version 3.10.11

Re: G-sync Flicker Problem !
Are you talking about minor flicker (like 1% brightness changes) or major blackout flicker (going black for a moment)?pilgrimage wrote: ↑07 Oct 2020, 07:43Hi, LG49NANO866 Games may flicker when G-sync is enabled.

Major Flicker
Usually caused by firmware bugs or driver bugs. Try lower framerate caps such as a 99fps cap (there's a firmware bug on one LG model at the moment)
Faint / Minor Flicker
For minor flicker, flicker is caused by sudden framerate changes. Different framerates have different refresh rates which /occasionally/ has slightly different colors (for various reasons, such as GtGtime:refreshtime (frametime) ratios, as well as LCD pixel decay, etc). Usually like about 1% brightness difference. Which causes the visible flicker when framerates /suddenly/ change.
To minimize this, you want to adjust to minimum framerate gyrations:
- Game settings (less stuttery settisngs)
- Game on SSD (less diskload stutter)
- GPU upgrade (keep GPU fast)
- Framerate cap (cap at something like 117fps below 120Hz)
- Keep framerates well inside LFC range or well above LFC range. You don't want framerates wildly gyrating into and out of LFC range, since the transition-into-LFC and transition-out-of-LFC can be a cause of flicker.
Also, your display is FreeSync (aka G-SYNC Compatible), which can sometimes have more flicker than G-SYNC Premium since NVIDIA's G-SYNC tuning for flicker-related matters, can on average be better.
The VRR universe is full of subtle behaviors that needs to be improved by the multiple manufacturers;

Re: G-sync Flicker Problem !
What is the LFC? How can I set the LFC interval?
If the G-sync range you are saying is LG49nano866 40-120hz VRR range.
Thankyou for support.

Re: G-sync Flicker Problem !
In this case it means make sure you don't go near 40FPS. LFC will make the monitor jump from 40Hz to 80Hz. This can cause flicker with some monitors.pilgrimage wrote: ↑08 Oct 2020, 04:09What is the LFC? How can I set the LFC interval?
