nvidia freesync over hdmi

henson0115 · 10 Sep 2020 at 17:33

does anyone know if nvidia support freeesync over hdmi yet without/prior to hdmi 2.1 (i/e 1.4)? i presume not but the monitor im curious about is an LG 29WK500

If you mean G-sync compatible, yep. At least some cards do - RTX 20 series cards can do it on LG TVs which have HDMI only. Not sure about other cards and it probably starts with HDMI 2.0 not 1.4

Interesting. Currently im using a Samsung Q70R 55" tv it is 120hz and has Freesync. So I'm guessing it'll work ok with a 3080 via HDMI.

I have a QLED TV too and freesync over HDMI will not work on the current (RTX2000) nvidia cards. I had to buy an AMD 5700XT to do 120hz freesync.

I have a ru8000 Samsung and from what I could find it seems the freesync on Samsung TVs is AMD only unfortunately.
It is 1440/120 which I have been using with freesync, I guess I will just use it at 4k/60 with vsync with the upcoming cards. Luckily the input lag from vsync isn't as noticeable with a controller.

That suck.

Was thinking about may be getting the 3080, but I am not upgrading my 75" Samsung NU8000 anytime soon. Looks like have to pray that AMD can bring out something competitive...

I don't understand the logic of this discussion

The 20 series don't support it according to rob77, but it does look likely 30 series will. So it's worth waiting a few weeks to find out before buying.

2000 series does have vrr over HDMI, it's just Samsung TVs only support AMD freesync, not vrr.

henson0115 · 11 Sep 2020 at 17:15

its the version of hdmi that dictates as far as im aware, AMD uses a custom vrr implementation/none spec hdmi adaptation of Vrr.
Hdmi 1.4 and 2.0 doesn't have an official vrr built into the spec, but on 2.1 it is as far as im aware. im curious if i buy a 3000 card if freeysnc with work with my hdmi only freesync monitor (1.4).
I guess im curious if nvidia will add in support for older displays on the newer cards. i doubt it will happen, but most people thought NVIDIA wouldn't adopt amds version vrr over dp in the first place so yea there is that..
if not then i guess il have to wait for a bit longer to see whats what.

~~You can make Freesync TV's(NOT HDMI VRR) work on nvidia 2000 series using CRU.. There's a vid on youtube explaining how, its rather simple and easy.~~

Brain fart... It was how to make VRR TVs(LG C9, B6 etc) work on AMD.. my bad... disregard.

Jimbo · 11 Sep 2020 at 21:50

Well this sucks for me. I was buying a 3080 to replace my Red Devil 5700XT, and expected it to work on my Samsung Q70R TV with freesync via HDMI. As i just cant go back to monitor gaming now. Things are so much better looking and play so smoothly on the tv. I have a LG 34inch 144hz monitor too, i prefer the TV. So shall i wait for AMDs card or just use the 3080 and game on the TV in 4K 60fps. Will it be a bad experience without freesync? Fml.

LuckyBenski · 11 Sep 2020 at 21:53

I'm STILL confused. Where on this thread is the currently unreleased/untested 3080 confirmed to not work with VRR TVs?

Jimbo · 11 Sep 2020 at 21:57

Hope your right mate.

LuckyBenski · 11 Sep 2020 at 22:01

Me too, I'm still team green for now. I think they would be foolish not to include support, seeing as this seems to be the way high end TVs are going.

HDMI VRR is different than Freesync over HDMI. Some TVs support HDMI VRR others Freesync over HDMI and some both. Nvidia should without a doubt support HDMI VRR on TVs with support for it, while it's uncertain if they will also support Freesync over HDMI on TVs with support for it.

nvidia will use the hdmi vrr spec which only exists as off hdmi 2.1, anything prior to 2.1 is none spec, hence likely wont be supported/only work on amd cards, nvidia only supports vrr/freesync on dp atm. so whilst it remains to be seen either way, its likely that older freesync/vrr tvs wont be supported on nvidia cards.

so you are saying nvidia will support a spec that doesn't exsist prior to hdmi 2.1? do you have any evidence of nvidia taking up support of vrr in the old hdmi standards? this will be a good outcome if the case.

Nvidia is already supporting VRR with Turing on a 2.1 enabled TV with support for it. While you won't get the 48Gbit bandwidth you will get the VRR support as long as your drivers are up to date. It works with TVs like LG C9, E9, B6, and CX. Plenty of videos around showcasing VRR in action on LG's OLEDs with Turing.

im not talking about hdmi 2.1, im asking about 2.0 and 1.4 and if they will implement the non spoec vrr associated with these two versions, i already know about the hdmi 2.1 and vrr becoming apart of the actual spec, you seem to have missed the point.

I'll be going back to AMD if freesync isn't supported on my Samsung Q70R tv then. I'm not holding out much hope now though. It's a real shame if so as I was all set on Nvidia 3080 I haven't owned an Nvidia card for a long time. Well I hope big Navi is going to be competitive.
