Been waiting for this. Digital Foundry just published their initial impressions of Nvidia's new drivers which now support freesync monitors.

Digital Foundry tests Nvidia's FreeSync/Adaptive Sync - "It's a game-changer"
- Thread starter Wintermute
- Start date
This is great news and with VRR being pushed into the TV segment it just might mean it will be adopted industry wide.
Hopefully by 2021 we can start calling this a mainstream feature especially with the new consoles that will help out pushing this.
Nvidia didn't implement this for HDMI. It's DisplayPort only :/
The big issue right now is that Gsync still isn't supported over HDMI. Not sure what's holding Nvidia up on that front.
the offscreen capture is really well done.
(i do wonder though what that unknown usb device in the device manager was)

That's odd, I thought I had a 120hz 1080p HDMI connection from my pc to my tv but I guess windows is lying to me
The problem lies with more than higher hz. 120 hz is fine. 144hz at 4k or 240 hz will be problematic via HDMI 2.0.
I'm very impressed with it. Tried it last night on my Freesync monitor and the results were very impressive.
I'm happy with Nvidia for this and I hope they move forward with more pro-consumer features like this.

HDMI 2.1 alleviates this. Yet, there's still nothing announced. Maybe they're waiting on the launch of their 7nm cards that have HDMI 2.1 in order to talk about it?
With HDMI 2.1 it should be easily possible. The bandwith was only in regard of 2.0.
Nvidia maybe waiting for Computex.
According to Reddit, you don't turn on Freesync on that monitor. it's just enabled by default:
https://www.reddit.com/r/Monitors/comments/84y1x5/how_do_i_turn_on_freesync_on_acer_kg240/
But then how do I turn on Gsync? There's no option in the Nvidia Control Panel.
Do you have the latest driver? You don't see the options that are in this tutorial? What card do you have?

That's correct, the "Set Up Gsync" option is completely missing from the menu. I have a GTX 970 and the latest drivers.
Here's the issue: that Reddit thread (which I've seen previously) says Freesync on the KG240A only works over HDMI, but I have it connected via DisplayPort. But Gsync only works over DisplayPort. Is this the problem? That Freesync isn't active, therefore the Gsync option won't appear?
Ah, you probably need the HDMI connection to make it work. Do you have an HDMI cable around you can try?
EDIT: Wait, I completely missed that you have a 970. You need a 10 series GPU
I hope they test a better Freesync monitor in the future. One with a proper high refresh rate range and support for LFC.
Hardware Unboxed tested a wider range of Freesync displays with some outstanding results more appealing to high refresh rate PC gamers. Even showed off VRR with HDR.

Overall take away it works as well as Freesync on an AMD GPU.

I'll try it when I get home, but I'm also about to build a new PC anyway with a Gsync monitor so this exercise is merely an experiment to see if it works on this particular monitor.
Does not work on your series of GPU. VRR only supported from 10 series and up.
As far as I heard, you straight-up cannot use Freesync on an nVidia card via HDMI. I'd love to be wrong though.
They did say to our editor at CES 2019 they might explore it in the future. I guess the best way in the meantime would be just to get the upcoming Alienware OLED which comes with a DisplayPort and should definitely work.
Yeah, I was just making a shot in the dark. I missed the part where he said he has a 970. That's his issue.
The GPU's can support VRR over HDMI 2.0 like AMD do. Nvidia just has not enabled it yet. They might in the future.
What does a theoretical 240hz 4k tv have to do with nvidia not supporting 1080p 120hz vrr via HDMI on 2019 televisions?
Current TVs, like last year's samsung QLEDs have AMD Freesync over HDMI 2.0b.
FreeSync over HDMI has nothing to do with this feature. That is a proprietary AMD extension to HDMI that's supported on particular displays and AMD GPUs.
Nvidia have added support for VESA DisplayPort Adaptive-Sync. This is a DisplayPort feature. It's only supported on GTX 10xx and RTX 20xx GPUs because it requires DisplayPort 1.2a which was not available on earlier GPUs.

It depends a lot by monitor, AFAIK. That's why Nvidia is doing the whole "Gsync compatible" branding thing. Even if much cheaper monitors can support and do support Freesync, you have to do your research, and you get what you pay.
I have a question about this. If all Nvidia did was support the basic VESA standard then how is it their driver seems to work great with AMD's Low Frame-Rate Compensation which is specific to Freesync (iirc)? It doesn't seem to me (no an expert by any means) that this isn't just a simple implementation of Adaptive-Sync.
Because TVs do not have native Gsync support.
VRR is a HDMI 2.1 standard. It can updated through firmware update if Nvidia should do so.
The new LG OLEDs which come out this year should have higher resolutions. But maybe only 120hz still because of the panel.

Venders can offer HDMI 2.1 VRR spec in HDMI 2.0b devices some TV's in 2019 will support VRR as outlined in HDMI 2.1 spec in their HDMI 2.0b only implementation.
HDMI Licensing Administrator talked about it with HDTVTest during their interview.

I'm sure Nvidia will support VRR over HDMI 2.0b, but it's understandable they don't support it out of the gate they might be waiting on HDMI Licensing and certification to be completed.
Just out of curiosity, is your panel one of the 12 they stated passed their testing?
I'm afraid you are completely wrong. This has nothing to do with bandwidth. There are FreeSync capable TVs available since last year and Xbox One also supports FreeSync. AMD GPUs support FreeSync over HDMI for at least 3 years.
FreeSync over HDMI requires HDMI version 1.2 and up.
Seconded. I had the same issue with Digital Foundry's Xbox One VRR video. They need to purchase 1-2 higher-range FreeSync2 monitors to test with.
Otherwise good job. And that takeway, I'll take one step further- moving forward there's no reason to pay the $150-400+ GSYNC tax if you are willing to do research into which FS displays work well.
Won't work with 980 Ti you'll need to buy a GSYNC display. VRR support for Freesync displays is from 10 series and up.
Yup, their testing was terrible because they went with such a limited range display and pointed out all the issues of MS's implementation however if they had a Monitor or TV that actually supported large VRR like the Samsung TV's at 1440p @ 120Hz or countless Freesync monitors that support a large VRR they would have seen it works great together.
This freesync stuff only works with 10/20-series cards, so you'd still need a g-sync branded panel
I agree with you, but the Samsung TVs don't have Displayport so they wouldn't work.
