Purchased a LG OLED TV monitor with G-Sync and HDR technology. It occasionally starts flickering when running MSFS 2020. It gets so bad that the only solution is to turn off the monitor for several seconds. It solves the  problem but ultimately the flickering returns. I was reading that gaming on a Window PC with G-sync and HDR is usually an issue (flickering), especially with LG TVs.  Has anyone experienced this issue? Is there a known solution or should I get rid of this thing?

Have LG 55 inch OLeD , had no issues so far. Working fine, some screen tearing which I can not find the reason but overall I’m happy. G-Sync and HDR have no idea how and where to enable. Some help should be appreciated

On your computer, click on the windows icon and type Nvidia Control Panel.  Then click on 3D settings and select G-sync. You should have the option to enable G-sync. After you enable Gsync, hit apply to save the change. 
 

To enable HDR, simply click on the windows search bar and type HDR. A window will come up giving you the option to turn on HDR. Once  you have done this, the imagine on your monitor will dramatically improve, but you might get occasional flickering which is annoying. The flickering means G-sync is working. Not sure there is a known solution for this issue.

Enabling G-sync should fix the issue of tearing.

in MSFS 2020 or 2024, make sure you enable HDR in your settings.

I had this issue and I fixed it by selecting "enable for windowed and full screen mode". If you have a second screen make sure to uncheck "enable settings for the selected display model".

I have no problem with my LG 42" OLED. G-Sync off, HDR off, game optimization off.

Turn off Bloom in FS2020 and Lens Flare

No problem with my OLED LG TV Monitor, also limit your FPS below 40 on 120hzs monitor.

The flickering is caused because of G-Sync, and your lower FPS. Once you dip below 70-60-50hz (frames) then the flickering will start as your monitor tries to sync with the frames. Some displays will flicker when using VRR and FPS gets too low, or if there's a very wide FPS variation. Not much you can do about it. Long story short, the worse or more sporadic the frametime performance is in a game, the lower the FPS are, the worse the near-black OLED VRR flicker will be. 

Don't do as suggested and limit your frames to 40, because the G-Sync range of this monitor is only 44-120. Therefore you'll end up disabling G-Sync and getting a choppy image.

 

What you can do is use some type of frame generation (or if you have a 4X series card, use the built-in frame gen in MSFS), However, I recommend Lossless Scaling in conjunction with RTSS, and that will resolve your issues, and allow you to continue to use G-Sync. It will smooth your frame pacing out, whilst providing a higher frame rate, eliminating the OLED VRR flickering and allow G-Sync to continue working smoothing the image further.  See my guide or contact me if you need help.

 

PS it has nothing to do with Bloom or lens flare.

This is where high HZ TV/Monitors require high FPS. So for all of those asking, what's the point in higher than 30/40/50 FPS etc.... This is one of those scenarios where it is entirely useful to be producing 100FPS and a good case scenario for it. As more and more people purchase g-Sync TV/Monitors with higher HZ and with VRR of 44-120, then this use case will be needed more and more.

This makes sense. I read a similar post explaining this issue. I think my monitor refresh rate is 144.

I noticed that when my FPS increase beyond 45 or 50, the problem goes away. When my frames are low in a heavy and demanding scenery, the flickering fest begins.

I have a RTX 3080 so my card cannot take advantage of frame generation. I plan to upgrade to the 5090 or 5080 graphics card so hopefully more frames means no flickering.

In the mean time, too bad because the quality of the image with both G-sync and HDR enabled is absolutely stunning.

Yes it can, as I suggested use lossless scaling app. It will resolve your issue by using frame generation using your 3X series card. If you lock at 38 using RTSS, then use my guide to setup lossless scaling and set it to X3 frame gen, you’ll get 114 frames per second, meaning your monitor will run at 114hz  using g-sync, and eliminate the black OLED flickering. 
 

Or if your monitor is 144hz then lock your frames to 46, then use my lossless guide again, and you should get 138 frames per second and your monitor will sync to 138hz using G-sync.

@Ianrivaldosmith  Glad to see you back Ian.  You always have lots of solid advice on these matters.

Where can I get the lossless scale app.  Currently, I have the MSFS AutonFPS app. Can they run concurrently?

Yes, get RTSS too, you need to smooth your frame pacing.
 

 You can get lossless at steam for a few quid/bucks.

Where is your guide and can I use AutoFPS and Lossless scale concurrently? Can my monitor really sync to 138hz?

Yes you can use Lossless and autoFPS together. and if your range is 0-144HZ then yes you can.

You have G-Sync, it can sync the frame to any frame between 44-144. You need higher than 70-80 ish to avoid your screen flickering.

 

For you I would recommend first capping your frame rate to 38 frames per second, and then using lossless frame gen x3. That should give you a good even frame pace and 38X3 =114 frame per second. therefore running at 114HZ. If that works all ok, consider a higher frame cap.
