G-sync compatible or w/e. It's not like it has modules in it, theoretically nothing should be stopping AMD from supporting the exact same protocols via their software also.
The eARC on 2019 LG oled has trouble passing through Mutil channel pcm at the moment, only stereo PCM and bitstream works at the moment, not sure if future firmware will fix this.
With AVR, one solution is to output the audio via your motherboard HDMI/optical, then display only from your Nvidia directly to your TV.
I thought about that idea as well.
I think it is better for lower latency as well, when you go directly from your graphics card to the HDMI port of the TV.
I only have a 2.1 setup. And Mainboard optical on board. I will consider this, when the update has been launched.
We don't know if Pascal cards are capable hardware wise. There is more in GPUs than just the core.
yeah but not on Pro :'D
Other then that, from what I've saw in an old DF video it doesn't work at his best, so I hope developers will take that in mind that when they will make future games for the next gen
It won't get you Atmos if your TV doesn't support it which is my issue.
"G-Sync Compatible" not G-Sync.
The TVs already supported HDMI-VRR, all this means is that they have now been certified by NVIDIA.
The real news here is not anything on the TV side, but that NVIDIA are adding HDMI-VRR support to their Turing GPUs.
My understanding is that AMD currently supports FreeSync-over-HDMI, but not HDMI-VRR. So they work with Samsung TVs which support both, but not these OLEDs.
If the display supports 48–120 Hz, that is a wide enough range for Low Frame-rate Compensation.
NVIDIA do not specify, but AMD require a maximum refresh rate ≥2.5x the minimum to support LFC.
LFC means that VRR will be active across the entire range in 120 Hz mode, as anything below 48 FPS can be multiplied and still supported by the display; e.g. 47 FPS at 94 Hz, 23 FPS at 92 Hz etc.
The issue will be 4K60 VRR. If the range is still 48–60 Hz, VRR will disengage below 48 FPS. I'm not sure how NVIDIA handles that - I would have thought it'd fail the "G-Sync compatible" certification if that were the case.
There are ways you could make it work though, since it's a 120Hz panel; e.g. have the TV report a 24–60 Hz range even if the panel can't refresh below 48Hz, and have the TV scaler handle the doubling.
I could be wrong, but I thought it was limited to 60Hz and did not support LFC on Xbox? That would severely limit its effectiveness.
Very low (~6ms at 120Hz, ~13ms at 60Hz) and total game latency is reduced further by using VRR in place of V-Sync.
I see this a lot, and I don't really agree.
While VRR is unquestionably better for variable frame rates, it is far more noticeable above 60 FPS than below it, in my opinion.
VRR doesn't "fix" low frame rates, it just makes them… less bad. Even if 45 FPS no longer stutters on a VRR display compared to a 60Hz display, it's still only 45 FPS.
Without VRR, you would have to target 120 FPS on a 120Hz display, which is very difficult to achieve consistently in most games.
With VRR, you can target an average frame rate of say 90 FPS and fluctuations above or below that are rarely noticed.
VRR is best for pushing above 60 FPS, not making <60 FPS more acceptable.
eARC is the future. eARC is a full-bandwidth audio return channel, rather than being severely limited like ARC - which was effectively an S/PDIF connection.
You will connect source devices directly to the display, or via switchers, and the display will pass through the audio to your AVR.
Now you no longer have to worry about your AVR blocking or interfering with features like 3D, HDR, VRR etc. All it does is process audio - as it should.
I just hope that eARC adapters will be available inexpensively for older audio devices that do not support it natively. Requiring eARC on both ends of the connection is the one main flaw with the standard.
You should not be using S/PDIF for anything other than stereo audio now. It doesn't support any of the modern multichannel audio formats; only heavily compressed formats.
That's not necessarily true. VRR is an optional part of the HDMI (2.1) spec so there may be hardware changes beyond a standard "HDMI 2.0b" port which AMD have incorporated but NVIDIA have not.
I don't recall the specifics, but AMD have always built more "robust" video outputs into their GPU designs, which are more flexible; e.g. NVIDIA being limited to 3 displays per GPU.
NVIDIA have generally been good about supporting their older GPUs where possible, and not locking out features via software; e.g. DX12 support on Fermi, which was crazy.
It's just that their hardware implementations tend to be built for "now" rather than being more robust and future-thinking like AMD.
It's limited to 60hz at 4K due to the actual bandwidth, however, I think can work up to 120hz at 1440p.
The bigger issue here s that next to no games have both v-ysnc enabled (a prerequisite for VRR to function on Xbox) AND have no framerate cap, so you can rarely go above 60fps even in 120hz mode.
The Xbox does have an LFC like system, so you get a benefit even in 30fps capped titles.
Hopefully they will be able to improve that with a system update. The 1903 update to Windows 10 added an option to force VRR support in UWP games released prior to its inclusion (though I still don't see that option with an NVIDIA GPU).
It's good that there is LFC support if the display is capable of it; I didn't think that was supported at all.
Playing Gears 5 on my X and C9 is and incredibly smooth experience eith VRR. I don't think I've played a game with a smoother frame rate. It almost feels like the soap opera effect. Oh the HDR is on another level. Highly, highly recommend the C9 for gaming.
99.9999% chance that Pascal is capable. This mostly comes down to HDMI spec and both 10 and 20 series have the same HDMI 2.0b. Nvidia can't hide behind their usual Tensor cores excuse for this one.
Of course, but that might not be an option for the person I quoted which is why I suggested either HDMI or optical, with the former obviously being the preferred option if available.
To be fair this news isn't related to HDMI 2.1 bur rather if TV has VRR support on HDMI 2.0b.
VRR isn't part of HDMi2.0b spec. Moreover, having support for the same version of HDMI doesn't mean that the display controller in both architectures is the same.
VRR has been supported on select HDMI 2.0 TVs since 2018 and computer monitors even before that. Implementation discussed in this topic is relying on HDMi2.0b signal, not HDMI 2.1.
nVidia released a new Game Ready Driver, 436.30:
Seems they already added support, only LG has to roll out the update for the E9 and C9.

I'm personally sitting at 6 feet from my 55 C8 and I'm ok, I wouldn't go any closer though.
Neither is freesync..
There is plenty of space in the HDMI spec to allow for manufacturer specific data to be sent - this is part of the spec.
The standardisation of this data is what actually gets specced in with revisions alongside other hardware and signalling changes.
As has been mentioned before HDMI 2.1 does not guarantee any specific features or hardware, it just means that the devices can understand each other even if one of the devices doesn't have the capability, it can understand it doesn't have the capability as can the other device.
Same. The 'problem' is I have a 65" so I would want to go bigger and the 77" is still quite pricey. Then again if the C9 is quite a huge step over the B6 then I could always just get another 65".
Or buy one now and use it with the consoles that do support it already
That's what you're doing, not me lol, this is huge for pc gamers that have the PC connected to the TV, like myself.
Meh, as a recent (as in, one week lol) owner of a C8 because the C9 was just too expensive for me, I'm not too bothered. I don't game on PC and I doubt the landscape of console gaming is gonna change with this.
Of course if you're buying a new TV next year the C9 will be a no brainer because it will be more affordable like the C8 is now.

Interesting. If true, people with Samsung VRR capable TVs and RTX 20 / GTX 16 series GPUs should try it out because Nvidia said you'll be able to force Gsync on any HDMI VRR TV. I have Samsung TV but not RTX 20 :(
Although I suppose Samsung TVs, just like LG TVs, might need firmware update as well to support Nvidia's implementation.

Unfortunately I do not have an QLED, if I had I would try it. I hope there will be more reports though.
Right I had assumed no FPGA module. Just wierd that it isn't being listed as having both VRR technologies through the HDMI scaler.
There are FOUR h/w options for adaptive sync support currently:
1. VESA Adaptive Sync (DisplayPort 1.4a+)
2. HDMI VRR (allowed to be implemented on HDMI 2.0+ ports currently I believe)
3. AMD's Freesync-over-HDMI (which is most likely AMD's own implementation of VESA Adaptive Sync on HDMI connections)
4. Gsync h/w obviously which works with DisplayPort only right now
There are TWO s/w stacks for handling such support over these FOUR available h/w options (maybe three - I'm not really up to date on Intel's shenanigans here):
1. AMD's FreeSync - currently works with any DisplayPort connection supporting VESA Adaptive Sync and with HDMI connections which have AMD's Freesync-over-HDMI implemented in them.
2. NV's Gsync - currently works with Gsync h/w over DisplayPort, with any DisplayPort with VESA Adaptive Sync support and now, starting with this driver - with HDMI VRR via HDMI 2.0+ connections.
That last option of HDMI VRR is open for AMD to implement into their Freesync s/w stack too and I'm sure that they will - question is if they'll be able to do it on their current HDMI 2.0 GPUs like NV did on Turing or they'll have to add HDMI 2.1 ports first.

They are allowing HDMI 2.1 VRR to work on Turing HDMI outputs - presumably with any display which has support for HDMI 2.1 VRR - and are certifying LG's 9 series TVs as "Gsync Compatible".
I hope to get time to test with this driver tonight as I have a 2018 Samsung with VRR.
Based on the current compatibility list, there are some monitors that show as 'Gsync compatible' that still show HDR support.

thats crazy awesome, I love my 2017 B7 LG OLED but would definitely see next year as a great time to upgrade. Playing Cyberpunk 2077 off a PC with RTX on a 65" OLED screen with VRR or gSync... omg
I agree about waiting for more info, but this list at least seems to indicate that it should work.
https://www.nvidia.com/en-us/geforce/products/g-sync-monitors/specs/
But I won't believe it has simultaneous HDR and VRR until someone explicitly says so, or I see it for myself.
EDIT: Oh, it looks like I unintentionally plagiarized plagiarize
