Would explain why my C9 always looses the signal when i deactivate instant game mode.
Reason for disabeling it is you can't use the smooth gradation settings while instant game mode is on. Would like to test this settings for ghost recon breakpoint, because this game has again serious colorbanding issues like wildlands. And HDR makes it even worse.
As someone else already pointed out, IGR is required for VRR. I used to have smooth gradation enabled before, but G-Sync is such a game-changer that it's worth the trade-off.

My Sony 1070 receiver doesn’t support eARC.
My receiver also doesn't support eARC, and regular ARC had audio delay issues, so I just connected a digital optical audio cable directly from the Xbox to the AVR.
You don't get lossless HD audio that way, but most games don't support those (a handful support Atmos, but I'm not sure if it's really the lossless Atmos or the lossy one), so it's not a big deal, to me.

Yeah, it's a driver issue, as the author of that video confirmed. The only workaround is adjusting brightness levels, for now.

NVCP set to 422 / 10-Bit / Limited. Running everything at [email protected]
- 1440p is snappier but since I don't play competitively, I prefer the IQ at native resolution. Tried just leaving at RGB /8-Bit/Full but would get mismatched black levels in some games like AC:Odyssey.
TV Brightness at 47 and Nvidia color setting at 52 to mitigate raised black level. Next notch on slider is 55, but I prefer slight crushing of blacks as opposed to them being elevated.
Input set to Console/Game mode - this eliminates nearly all of the banding that is on PC Input mode.
GSync for window/full screen and Vsync on in control panel - off in all games. Use in game limiters at 57 where its an option like Borderlands 3 and COD:Modern Warfare. (55 for AC:Odyssey). For games with no frame limiters I use RTSS set at 57, not as good as in-game limiter but better than setting with Nvidia Inspector tool.
Dynamic Tone Mapping set to HGIG for future support - basically off for most games. I can see the appeal of having it on for a lot of games, but it makes night and indoor scenes way too bright for my liking. Since I am using Console input mode I can use Dynamic Contrast to make slight to modest lighting changes on games.
For SDR gaming I set to RGB/8-Bit/Full and just disable the HDR mode in display settings. I keep my black level settings the same as HDR.
The oval shape people report is a side effect of game mode as I see it on Xbox (Console Input) as well as PC (PC Input). I barely notice it if I have OLED light at 65 or higher on SDR. I never see it on HDR mode - might be because OLED light is at 100.
I use pretty much the same settings, except I don't bother changing color format/depth, anymore, and just leave it at YCbCr422/12bpc for both SDR and HDR content. Do you see any difference from RGB/8bpc/full? HDR needs at least 10-bit to be displayed correctly, so that's probably what you saw with AC in RGB/8bpc.
I'm also not a fan of Dynamic Contrast, and prefer DTM. Oh, and you can gain a few FPS in G-Sync if you add a custom resolution with a higher refresh rate, such as 66Hz, using CRU. I've posted the instructions a few pages back.
Lastly, I only noticed the oval shape bug when playing Xbox. Even PC with input set to "Game Console" and the same picture mode/settings doesn't have the same issue.

The only thing that fixes the black levels in HDR at tv brightness 50 in any driver after 436.51 for me is running at 2160p and setting the color settings to 4:2:0 12-bit. The problem with that is that I mainly game at [email protected]
after the Gsync update, and that res doesn't support 4:2:0.
That (ugly) video of mine actually makes the problem seem a bit worse than it actually is, but it's definitely a problem.
I'm going to try the suggested brightness at 47 and Nvidia color setting at 52. Thanks for the great suggested settings post you made earlier, @Mabelrode
YCbCr420 hasn't an option here since the G-Sync drivers, regardless of resolution, refresh rate, input and picture modes. Not sure why.

The issue occurs regardless of G-Sync. It's really related to the driver itself, and not just to some specific setting.

I mean if you turn on gsync and set the framerate limit in rivatuner to 57 globally, I'm positive its introduces stutter when watching movies in Potplayer.
The whole thing is a mess, can't wait till hdmi2.1 cards arrive.
You can exclude certain programs and applications through the Nvidia Control Panel. Go to "Manage 3D settings", click on the "Program Settings" tab, select the program from the list (or click on "Add" to find it), and set "Monitor Technology" to "Fixed Refresh".
It doesn't work for some programs, however, such as Firefox (in full screen mode, there's tearing at the top of the screen).
