Not sure if this was mentioned, or exactly where to post this, but I just saw mention of it

LG G-Sync Compatible 2019 OLED TVs

  • 65-, 55-inch E9
  • 77-, 65-, 55-inch C9
Other features in its 2019 lineup that make the TVs appealing for gaming include HDMI 2.1 features like variable refresh rate (VRR) and Auto Low Latency Mode (ALLM)
 
That's nice. But G-Sync compatible is not the same thing as a hardware G-Sync module.
 
Wait what? Gsync through HDMI? I'm confused.

That's what it says. This was always going to happen eventually. Good news... if only they'd actually put HDMI 2.1 on the RTX cards you'd be able get more than 60Hz!!

This doesn't work on the C8 then? Wonder if it will, just not 'officially'. Do they get same firmware updates?

2018 models didn't support VRR or HDMI 2.1 iirc - those were almost the only changes made in the 2019 model
 
Can a display simultaneously support VRR and Gsync? I wonder if they will support VRR with next gen Xbox and PS5.
 
Thank you for posting this! This just sealed the deal for me taking the plunge on a 55” C9 OLED! Couch PC gaming setup here I come!
 
This removes what little reason I had to look for a new gaming monitor. I look forward to playing Cyberpunk 2077 on a 65" G-sync OLED. :)

I was hoping for a desktop OLED, but yeah, after hearing this, my next PC may go in the living room.

Also I have a 55" C7 that looks perfectly fine, but a 65" sure would look better on the wall there (and I could move the 55" to my bedroom)....
 
Sorry but slightly off topic

Does anyone know how VRR would work through a receiver? There doesn’t appear to be any 2019 receivers with natural HDMI 2.1. Only ones that had HDMI 2.1 features added on such a eARC. I’d like to get a nice 7.1 system going through a receiver but I don’t think Gsyc would work going from GPU->Receiver->LG OLED? Should I just try to find a receiver that has those 2.1 features added into it or do I just need to do audio through traditional analog ways and skip HDMI audio for now? Any advice would be appreciated. I would rather take advantage of the Gsync (thinking of running 1440p @ 120hz until the new HDMI 2.1 GPUs come out which now looks more promising from Nvidia. Thx!

I think LG will be releasing 48" OLEDs next year, but that's probably still too big for most people's desktop.
 
YESSSSSSSSSSSSS.

I wonder if HDMI gsync will only work on RTX and 16 series cards or if that's all it will be official on. I want to wait to get an HDMI 2.1 card, but I don't want to wait to use OLED VRR.
 
It is indeed HDMI gsync. :)

Aka VRR an open standard which some Nvidia people were shitting on until the last year or so because that's the way AMD went from the beginning (no G$ink modules). Now it's great because it's 'G-Sync via HDMI' lol. Damn marketing suckers.

The current models already support VRR which is freesync compatible, which Nvidia finally allowed its users to do after it being around for years(outside of laptops), so you can already do this.. but it's not HDMI 2.1, which is the difference here for 2019.

Anyway this is great news. The beginning of the end of the shitty, permanently hobbled PC monitor niche market and I welcome our superior TV overlords, as long as they offer them in a range of sizes and keep the input lag down, with the refresh rates, colour gamuts and contrasts high..
Really, one screen design (and size range) should be able to do all for most users..

Ok HDMI VRR whatever but I mean the hate was slightly understandable at first because that open standard implementation caused display makers to have piss poor VRR range with no LFC and no variable overdrive as well. Had display makers put in extra time to have proper LFC and variable overdrive like Nixieus i think the opinion would've been different.

It is not very likely that the average LCD TV will ever qualify for G-Sync Compatible. Most of them don't have the pixel response time, especially without variable overdrive. As others mentioned, HDMI VRR is perfect for OLED since it has much faster pixel response times than any LCD.
 
Keep in mind that the panel lottery is still a thing even in this new Golden Age of OLED, lads. If your panel can display this in fullscreen with no issues you're golden:

Otherwise see if it will do a compensation cycle when you turn it off. If it doesn't get better getting a replacement from a retailer is still easier than an RMA through LG so make sure everything checks out within the first 30 days, 2 weeks, or whatever you get in your jurisdiction. Good luck!

Yeah you could see manufacturers offering freesync panels with gimped ranges and then consumers unlocking these ranges. Was it them or nvidia? Either way I agree it was a shitty look for freesync. The panel testing for approval should have been more stringent like gsync more often was, hopefully those days are a thing of the past soon.

VRR over HDMI has always been proprietary implementation afaik. Having it also on Nvidia cards is great news though because it makes them ready for next year's TVs as well as existing TVs with Freesync support. G-Sync modules are still the overall best implementation of VRR but having other options that work on Nvidia is very very welcome.

Now if we could only get top tier TVs that are not 48" and up so they could be used on a desktop without having the deepest table you can find.

So basically, these are high-quality Freesync screens?

No, the LG C9/E9 series supports HDMI Forum VRR, which was added as part of the HDMI 2.1 specification. Based on everything that I've read, HDMI Forum VRR operates similar in concept to NVIDIA Gsync, so I'm not terribly shocked the panels have received a firmware update to support Gsync after the fact.

What's still not known is what VRR range the panels operate in, as there currently aren't any HDMI 2.1 sources to test against. For comparison, Samsungs panels (which utilize Freesync over HDMI) have a very narrow 48-60Hz range when in 4k, and I know *several* people on these forums and elsewhere which are holding off a purchase until the range of operation is known. If the range is wide enough, I would certainly upgrade my B6 for one of these guys.

You will have to use eArc from the TV to the receiver to get 7.1 it Atmos to get VRR and 7.1.
 
This is amazing news!! I have been using my LG C9 at 1440p at 120hz and the motion clarity is incredible and almost crt like.

Will this work with a 1080ti or do I have to get a RTX card?

How do you I use gsync? Do I turn off vsync? Is there any settings other then turning gsync on?
 
Since OLED pixels speed are so fast that there is no such thing as "overdrive", you don't need the benefits of variable pixel overdrive. Hence why "regular" VRR will be just as good as G-Sync chip VRR on an OLED display.
I didn't know that. Well, if OLED VRR equals to hardware gsync module in performance, then this is really great news for those who feel comfortable with 55" display.

You gonna need rtx 20 series or gtx 16 seres.

Ah ok, looks like I will need to grab one to enjoy gsync on the C9. I imagine they are not able to offer 4k 120 from the RTX hdmi as it does not have the bandwidth? Looks like their hdmi on the rtx has some hdmi 2.1 features like vrr that can be enabled.

A feature can be added after the fact later, more bandwidth usually can't.

LG says the VRR range is 40-120 Hz, but since we don't have any video cards with HDMI 2.1 yet it will be limited to 40-60 Hz.
 
All LG needs to do is come out with a 32-43" OLED and they'll conquer the entire PC gaming monitor market.

Meanwhile, at Dell HQ: "Guys, do you think we misfired with our 55" $4,000 non-HDR non-HDMI 2.1 OLED?"

Not that it wasn't a near impossible sell already, but that Dell OLED is literally DOA now at the price they announced... paying more than twice for DP 1.4 connectivity, and no HDR, when you now get same VRR functionality (with HDR) over HDMI on LG TV's... HA!! But you do get RGB on the rear at least. :D
