I believe every Nvidia user has already tried to enable VRR on their monitors and they know by now which monitors works and which don't.
This official list is just useful when buying a new monitor.

Nvidia is just trying to slow down the demise of G-sync. Free sync was always as functional as G-sync and free sync always could work with Nvidia cards with the same performance as G-sync.

Why do you keep giving them free publicity for trying to rebrand the free standard they tried to monetize?

Vrr screens would of been 2 years more advanced, and also cheaper, had they not dragged their heels....

No freesync over HDMI yet, guess it won't happen.

This is not true.

Xx Tek Tip xXNo freesync over HDMI yet, guess it won't happen.

I'm pretty sure this is because the HDMI standard doesn't support VRR until HDMI 2.1, which no AMD card has that I'm aware of. I also think G-Sync only works over DP on "compatible" monitors for the same reason.

That's funny, I've had it working over hdmi just fine in 2 monitors or do you mean gsync???

No "problems" with Freesync over HDMI it's just limited to 100Hz instead of 144Hz for me.

Read the thread title and work it out, my KG221Q doesn't do freesync over HDMI on my 1080ti so perhaps read someones system specs and the thread title before making silly assumptions?

newtekie1I also think G-Sync only works over DP on "compatible" monitors for the same reason.

It's because of they're supporting VESA's Adaptive Sync and not AMD's FreeSync apparently, if Nvidia actually implemented proper freesync support they could be able to support it over HDMI or is it a hardware limitation?

Perhaps specify a certain hardware config that doesn't support freesync over hdmi before making a blanket statement. :kookoo::nutkick:

Perhaps read the thread title of "G sync compatible" and use your brain to figure out people here clearly aren't going to comment about freesync on AMD hardware.

You made an incorrect statement, the thread title has nothing to do with your 1080ti and monitor not being able to do freesync

Fanboys don't work like that. They just rage on keywords :D

The confusion here is that while G-Sync will work on FreeSync capable monitors, Nvidia does not do FreeSync. FreeSync is something AMD has built on top of AdaptiveSync. FreeSync uses AdaptiveSync over DisplayPort and something else over HDMI. FreeSync is governed by AMD, AdaptiveSync is governed by VESA. It's pretty obvious why Nvidia doesn't go for a solution governed by their main competitor.

Ah now I understand a shame really since it would've been nice to try it out but it's only a secondary monitor anyways : )

It's still better over DP regardless. It gets limited because of bandwidth and it's all down to the monitor really, has nothing to do with GPU hardware limitations within HDMI 2.0s limitations of course.

INSTG8RIt's still better over DP regardless. It gets limited because of bandwidth and it's all down to the monitor really, has nothing to do with GPU hardware limitations within HDMI 2.0s limitations of course.

Of course it is better over displayport, but try plugging a displayport into a monitor with HDMI and VGA then? Anyways enough since the thread is just getting derailed at this point.

Wait a sec, the Acer KG271 Bbmiipx has only Hdmi and VGA port!, does that mean Adaptative sync over HDMI is coming for Nvidia card owners ?

What's the difference?

Afaik freesync was just amd branding the vesa standard for adaptive sync?

I just told you what the difference is, read my post more carefully.

bugI just told you what the difference is, read my post more carefully.

I must be blind as I can't see where you say anything about the differences.

From what I understand amd just branded adaptive sync as freesync and puts the same tech into their drivers so it works. The only thing different is the way they make it work over hdmi too.

NdMk2o1oThat's funny, I've had it working over hdmi just fine in 2 monitors or do you mean gsync???

It depends on the monitor. HDMI 2.0b doesn't officially support VRR. However, AMD apparently uses some kind of trickery to get it to work with HDMI on some monitors. But it is my understanding that the monitor has to support HDMI 2.1 for this to work, though I could be wrong. But I know it won't work with every HDMI monitor, even if the monitor supports Freesync, it only work with HDMI on certain model monitors.

With nVidia, the G-Sync module in the monitor would accept an HDMI signal with their own VRR signal imbedded and then convert it to DP so the panel would accept the VRR even if the monitor wasn't HDMI 2.1. Monitors without the G-Sync module are forced to use DP to work with G-Sync.

Xx Tek Tip xXIt's because of they're supporting VESA's Adaptive Sync and not AMD's FreeSync apparently, if Nvidia actually implemented proper freesync support they could be able to support it over HDMI or is it a hardware limitation?

It is a hardware limitation of HDMI 2.0b. Like I said, official support for VRR wasn't implemented until HDMI 2.1. AMD is using their own trickery to get their HDMI 2.0b cards to output a VRR signal that the monitors can accept, and I'm guessing nVidia can't, or isn't willing to, do that.

Xx Tek Tip xXOf course it is better over displayport, but try plugging a displayport into a monitor with HDMI and VGA then? Anyways enough since the thread is just getting derailed at this point.

There is a Freesync monitor without DP? I don't know any.
As for VGA... Let's not talk about analog dinosaurs now. Certainly VGA can't support any sync variation to this level.

newtekie1I'm pretty sure this is because the HDMI standard doesn't support VRR until HDMI 2.1, which no AMD card has that I'm aware of. I also think G-Sync only works over DP on "compatible" monitors for the same reason.

One shouldn't want to use HDMI but AMD/a lot of monitors do support FreeSync over HDMI: www.amd.com/en/products/freesync-monitors

No NVIDIA card supports VRR over HDMI because they don't have the infrastructure to send VRR data over their existing HDMI connectors. That is to say, GCN's HDMI connections are programable where NVIDIAs which are fixed function. NVIDIA won't get VRR over HDMI support until they launch cards with HDMI 2.1 connectors.

newtekie1It depends on the monitor. HDMI 2.0b doesn't officially support VRR. However, AMD apparently uses some kind of trickery to get it to work with HDMI on some monitors.

It does not. I believe the only difference is in the EDID handshake and how data is arranged once VRR is agreed to. Monitor gives EDID that says it can handle a FreeSync range. Non-GCN cards ignore it; GCN cards respond with sending data over HDMI via frames and the monitor paces itself to the framerate.


I believe all cards (NVIDIA and AMD) that have DisplayPort 1.2a or newer can do VRR. I believe all GCN cards with DisplayPort 1.2a or newer can also do it over HDMI so long as the bandwidth isn't overflowed.


Only panels that are sent to NVIDIA for certification will get G-Sync Compatible label. The same is true of AMD and FreeSync.

SoNic67There is a Freesync monitor without DP? I don't know any.

My monitor (KG221Q) - that's why I've literally asked if nvidia would ever support freesync over HDMI, Some TV's also have freesync apparently but only have HDMI as well.

You don`t need Sync for gaming, @marketing.

Fake news.

Nvidia desperately wants people to believe it, though.
