None. Club3D said on their Twitter that they got it working but then retracted their statement as it was apparently a false positive. But that tells they are at least trying to do it. Just nothing new on that front yet.

After months of reading and re-reading this thread I decided to take a shot. I'm a Sony guy, so pre-ordered their new 48" A9S OLED instead of the LG. No idea when it'll ship, but I'll definitely post pics/comments when it's delivered. I still think 48" is too big for desktop use. Maybe I'll be surprised. Sure as hell hope so.

I'm an AndroidTV guy myself, but the Sony not supporting VRR/FreeSync/G-Sync (any of it) was a clear dealbreaker for me. And since they use the same panel and you can't use any of the motion processing magic on a PC anyways the LG CX is basically a no-brainer if you can get it..After months of reading and re-reading this thread I decided to take a shot.

Regarding size:
I got slapped in my face when I went from triple 20" to single 43" for about 2 months on my desktop. (I did use triple 1080p 40" on my simrig and for productive work/coding in the past though, so the size wasn't completely new to me). But I got comfortable with my big screen after a while - so much that I wanted something a hair bigger for (relaxed) gaming.
Now, 1 year later I'm at 55" on the same desk (as I couldn't get my hands on a 48" for a reasonable price) - and it's doable. I think 40"-48" is the absolute best size for casual, relaxed, lean-back gaming, even on a desk (or especially on a desk). Don't get instantantly scared by the size, you WILL get used to it.
They still don't have HDMI 2.1 I. Their newest model ~.~? LG going to be the better gaming TV.After months of reading and re-reading this thread I decided to take a shot.

Dude 55 on a desk? Is the image even sharp at that distance? I always figured you'd need 8K resolution to make something like that work as intended.
Nah, I had to use font scaling of 125% on my 43" to be usable. With the 55" I can now use 100% and it's perfect.
PS: even gaming in 1440p is perfectly fine on a 55"..

Wow, serious oversights on my part!
Thanks for the heads up. Sony canceled. Looks like it's gonna be LG for me, too.SixFootDuo

Looks amazing ... then I saw ... HDMI 2.0b ..... honestly, you don't want that. You want HDMI 2.1 ...... I promise you, 4K@120hz OLED is .... AH-MAY-ZING .... amazing.After months of reading and re-reading this thread I decided to take a shot. I'm a Sony guy, so pre-ordered their new 48" A9S OLED instead of the LG.

I have a highend Sony 75" in my livingroom. The LG is just as good quality, same exact high-end fit and finish. You will not be disappointed at all.
LG and Sony are some 2 top brands. Samsung has tanked their quality and features over the last few years.
my 2 cents.
Regardless of what you do, stay safe and enjoy.

I have the CX48 with 3.11.26 and a RTX 3080. Running at 4k Full RGB 120hz with HDR. Stuttering is very visible in Pendulum test. No tearing for me tough.
There's enough reports of stuttering where it's likely an implementation issue with the beta firmware, which is probably why it got pulled. It sounds like the "major" problem of Gsync flat out not working is fixed, but there are some frame pacing issues left to resolve.
I do give LG/NVIDIA some leeway on this, since this is the first implementation trying to get all this working. Some issues are expected. I do hope they get resolved soon-ish though.
Still holding for a GPU before I commit to the TV. Honestly might just wait for next years model at this point...
At least LG is trying to fix it. Samsung and other would of just said tough shit. Buy next year's model and it might be fixed there.

I was hoping the smoke would clear and major issues would be resolved before potential november deals (even considering 55" C9, E9, and CX models).. between november and xmas / end of the year... but if not I'll probably be in the same boat. The later they resolve the issues the more imminent next years model will be after a point. There's no guarantee the next year's model will be free of issues though. The raised near-black levels in VRR have been since VRR was implemented on the C9 late 2019 for example, and is part of a near black flashing workaround "fix" history. I'm not sure how long the dolby vision raised black issue has been around. Anyway the point is that I think most of the big issues like stuttering G-sync/VRR exist on both the C9 and CX so there is no guarantee that the "C11" or whatever will be free of problems that wouldn't be fixed in firmware across all of the more recent models in time. That is, assuming the issues are not hardware limitations in the end.

There is a hdtv-test video where he shows that if you spam the green button you get a link/resolution/refresh/vrr status window.
Mine on .26 firmware always shows 5.5Hz as max, where with vrr on it can variably drop. 5.5Hz in 120Hz content.
His video however, seems to show the proper refreshrate fluctuating just under 60Hz. Would be funny if the issue is that the tv doesn't properly report the refreshrate to itself.

So i thought id try every combination with the above status window to see what it says, and with instant game respone+amd freesync turned on + gsync in nvcp, it actually seems to work? Didn't have much time to try so please reproduce. (still maxes out at 5.5Hz for me).
But it seemed to work in the 10 min i tried, vrr working, no black flashing, no tearing. Not 100% about stutter as i tried in wow with very even frame times, but i didn't see any.
(tried a bit more (witcher3, wow, wowbeta, destiny2) works fine up to roughly 107fps cap. over that stutter in some games, like destiny2 - but it works! so anyone else stuck on .26, just enable freesync and cap to 106)

Do the 48CX and the 55CX have the same mounting dimensions for the stand?
Still have to come up with a proper mounting solution on my desk. Wall mounts are too thick, stands to deep.
Looks like I'll have to design something 3D-printed that's low profile..
Does anybody have information about the screw hole depth of the foot and vesa mounts?
Ideally I have a bracket that screws into the foot mount and extends below the TV around the LED and housing so it doesn't rest on the panel (right now I have wood chips under the box) and some solution that goes into the vesa mount and the wall so it doesn't tilt forward (that thing is unexpectedly front heavy)

Is it possible that the issue is relative to the window 10 option ?
>> Game mode >> do you active it ?
>> Materiel acceleration >> do you active it ?
>> vrr in w10 option >> do you active it.
What do you do of these 3 option ?
I am very curious if a person can test on a linux hardware if the stutering are visible with gsync on ?

Where do you enable any of those 3 options in Win10?
Game mode >>> parameter >>> game >>> game mode
Materiel acceleration >>>>parameter >>> system>>> display >>> parametre advances graphic
Vrr >>> same like materiel acceleration.
I am french so i am not sure what is the name of your menu.
I am very interesting to see what theses option do on your system, and what do you think ?
Is is possible that the bug is a nvidia driver issue ???
Is nvidia aware of this issue ?
Have you try previous driver ?

I need some help with 4k / 120hz/ gsync WITH HDR on a LG CX using a RTX 3090. I can't get windows to turn on HDR. The switch is effectively disabled. Is there a setting on the LG that I need to enable/disable to get it to work? HDR works fine if the TV is at 4k / 60hz/ gsync. Actually, it comes on automatically when I switch from 120hz to 60hz. Considering the RTX 3090 is supposed to have HDMI 2.1, wouldn't this allow HDR with 4k/ 120hz? I am using a 48gps HDMI optical cable and my LG is on 3.11.10 (this is as far as my TV will allow as of today). Does a manual upgrade to 3.11.25 fix this?
What settings are you using within the NVIDIA control panel? Make sure to use at least 10-bit output. Aside from that, you need to enable "HDMI Deep Color" for the HDMI input you are using, since that effectively controls whether HDR can be supported.

Just dropping a quick note that today I "upgraded" to the LG 48CX from a 55" LG C9.. Prior to the C9 I was using an LG C6 (55" Curved) OLED and as I suspected while I was fine with the 55" as a Desktop Monitor the smaller size of the 48" is much much nicer. I would even say having used the Dell 43" 4K LCD's at work for some years that even if LG made a 43" OLED I would stick with the 48" size... its pretty much a perfect size for gaming and desktop/office work. Very Happy.

Make sure the hdmi input icon on the cc is set to PC. That will allow pc resolutions. In nvcp resolutions scroll down and select 4k. You can now set it to 120hz and enable hdr.

I’ve done my first round of gaming and have some findings on gsync.
pendulum shows stuttering. But in game Hell Let Loose no stuttering whatsoever and no tearing. Everything at epic - framed between 50-100.
Horizon Zero Dawn: no stutter. Frames around 60-80 all max. HDR is amazing. But tearing with Gsync... don’t know why. Also played with BFI. Not sure i actually see the difference.
Borderlands 3. Great HDR. 70-90 fps. No tearing or stuttering.

and if you enable amd freesync?
I was a nay-sayer about 48" and went with it anyway. But damnit, 48" is growing on me bigtime.

Its on on the tv.
What card are you using? I've got a rtx 3090 and an i9-9900k OC and I'm getting 45 -50 fps on horizon zero dawn with ultra settings. Are you in 4k?
It's been this way. I can get 4k 120hz easy. But never hdr.
The only setting that even allowed any 4k options is 8 bit ybbr4220. If I select any other option, it defaults to a very awefull resolution, and I must step up to 1080p first then fix the color options, then back to 4k.
I can simply select 10bit rgb with no issue with 4k 120Hz on my 3080, and hdr works. maybe properly clean driver reinstall, if you haven't?
Tried clean driver install too.
Perhaps it's the hdmi cable? I know those have been an issue. I ordered another 48gps hdmi, I'll be able to test it on Sunday.
This is a totally out there question.... But I bought the rtx 3090 from someone, "new", BUT, is it possible that he could have hacked the bios and gave me a "trojan horse".
That is a whole lot of effort to just hack you, a random person to sell to.
Not a hack.. just a classic scam lol.
PS: it took me 2 freakin days to realize that there is a glossy pull-off wrap covering the whole panel.. Wanted to pull off the sticker in the corner and off came 55" worth of plastic wrap
I knew it didn't look that glossy in the store..

Wouldn't be that hard to check; just check the length of the card. And this is done a LOT when there's a supply issue with cards; it happened a ton when bitcoin mining on GPUs was still a thing.
I've got a suspicion HDMI 2.0 is being used. You can get 4k120 using 420, and 4k60 10-bit HDR at 422 using HDMI 2.0.
At this point, given you apparently got the card from a re-seller, I'd verify what you actually have before doing anything else. I'd check the length of the GPU, since no other GPU is as long as the 3090 is. If it comes up short, then you've been screwed by you buyer. If the card is genuine, then you'd need to verify the cable somehow, since you shouldn't be having these issues. It's also possible the TV isn't being detected right; I had issues with my B6 initially so it might be worth checking with the GPU thinks the display is.

I have a new issue with G-SYNC in Dota 2. I use an in-game fps limit of 118 with Vsync enabled. The game runs smoothly for around 10 minutes before the fps suddenly drops to 60 and stays there. If I disable Vsync, it goes back up to 118, but it stutters terribly. Only restarting the game fixes it.
It's been months since I used a hardware G-SYNC monitor so I don't know if the issue is with the 3090 / CX, or with the game / drivers.
