55 IN C9 OLED VRR ISSUES

Ffink20001_

So I just got my c9 oled on Wensday, amazing TV. However having vrr and low latency mode issues with xbox one X. Plugged Xbox one x directly into TV and when loading a game that supports it like fallout 76 or Gow 4 the frame rate and image goes all haywire, even menu options of the guide.. However games that dont support it don't have the issues. Disabling both modes fixes the issue but what's the point of buying a TV for those modes if they don't work?
Do when disabling them when playing gears 4 and or Fallout 76 setting Hdr mode to game mode does the same thing. Is this an lg issue, or xbox one x issue?

New firmware is available. Patch notes are mostly about Alexa and minor bug fixes. Doesn’t mention Xbox specifically but let me know if it fixes anything. I don’t have time to install it right now.

Dampap, mbuck45, you definitely should connect directly to the TV HDMI.

mbuck45

Dampap, have you found an answer for this?

Running firmware version 03.60.19 on my LG C9 panel and X1X is up to date.  I have the X1X plugged into the SL10YG soundbar as this is the only way to prevent any voice lag while using ATMOS sound.  The only problem is that when I enable VRR/ALLM/HDR, I get a blank screen when starting up a game.  I can only choose VRR/ALLM or HDR but not all at the same time.  I can enable VRR/ALLM/HDR when the X1X is plugged directly into the TV but there is still some screen tearing and stutter in game, including the voice lag with ATMOS.  This is when playing Shadow of Tomb Raider.  I have the same problems with Division 2 with X1X connected to soundbar but haven't tested when X1X is plugged directly into TV.  I currently have the X1X plugged into the soundar with VRR/ALLM enabled and HDR disabled.  Using HDR Effect picture mode as an alternative and it does look nice with the added color vibrancy.  So far, it doesnt seem like there is much of a discernible difference between HDR Effect mode and HDR10 but it's possible that I haven't played enough to take notice.   Is anyone experiencing the same kinds of problems when plugging the X1X to the LG SL10YG soundbar and from that to the TV via HDMI ARC?

Planning to buy the C9 soon...   Happy to see issue resolved with the firmware update.  One question:  I have all my sources going into my AV Receiver (Marantz SR7012) - will VRR pass through the receiver, or is it better to connect directly to the C9 from the Xbox One X?

I‘m hoping the firmware update was for the e9 too, because i‘m still having the same problem with the hdr with my xbox one x. Hope it’s getting fixed soon by lg or microsoft.

RobPT45, thanks for the information.

Hi all!  The screen-tearing was fixed with the firmware update, but there are still problems with the X1X passing VRR and ALLM to the C9  I *think* the issue is on the Microsoft side, but here's my full analysis if you're interested:

Why have some of the posts disappeared from this discussion? I was looking for @SlimNebuloid
link to the firmware page and it seems to have disappeared, and some of the posts that were in direct response to it no longer make sense.

Incidentally, a new firmware was released 6/12 that isn't showing up in the TV's auto update. Anyone know where I can find release notes on it?

JamalofLG

raynmain, you can check for the update in the Settings on the TV (Settings > All Settings > General > About this TV > Check for Update). If it states "No Update Available", it will need to be downloaded from LG.com and installed on a USB.

If need be, the update and the instructions can be downloaded from here: https://www.lg.com/us/support-product/lg-OLED55C9PUA#manuals

@Ffink20001_ where can I download the update? Is it available on the tv or do I have to do a usb install?

Ffink20001_

Good news, I am glad I went back and happened to check this as I gave up on it being fixed, but downloaded the newest update, VRR now works properly. Everything I got the TV for works perfectly now. Thank you guys! And thank you LG for a great Television!!

dbjordan

I'm happy so far! Any else still seeing problems? Or is it time to close the thread?

JamalofLG

Great! Glad to here it was resolved. If there are any other problems let me know.

SlimNebuloid

I downloaded the update. It appears that they haven’t added the Alexa app to the content store yet for the new firmware. If anyone sees it up, please post. 

SlimNebuloid

Haha thanks. I’ve been checking frequently

I've had LG TVs for years now, and I can concur this is pretty standard. Most of my TVs eventually got the auto update if I ignored them, but the USB-only version was available sometimes weeks beforehand and it seems like some of them never made the cut to auto-update the TV.

I'm not sure if LG treats the updates as in some sort of incubation period available in USB only for a bit before they put them on their servers for everyone to get, or if there's a bit of review or server update time to position them to deploy that way, or if there are certain updates that aren't deemed significant enough to roll out using the TV's auto-update, or what. I've just noticed that it's pretty often that USB is available first and TV internet update comes later, if at all.

I tagged SlimNebuloid's post as Helpful, because I think this is actually the first time I've ever known to update my TV on day 1!

By the way, has anyone been successful in updating the firmware within the tv webos? Every time the "check for update" button on the tv information results in "no updates" message being displayed. I had to use the USB drive.

SlimNebuloid

Awesome! I’m excited to try it out.

pelleran

Forgot to thank SlimNebuloid for mentioning the firmware update!!!!

pelleran

I installed and checked. The stuttering is also solved. Can now play with the 422 option off and all is good! Thank you LG. 

dbjordan

I’m no longer seeing any tearing in VRR mode with this update installed!

Guys I think you are fundamentally misunderstanding what allow 4:2:2 does.
The Xbox One X supports the HDR10 standard at 4k 10bit 4:2:0 60hz.    It does not support 4:4:4 in 4K HDR.   Selecting ycc 4:2:2 does not allow compression below 4:4:4, rather it let's it use MORE than 4:2:0.    This is a chroma upscale, not true 4:2:2, and is for compatibility reasons only, as the native HDR10 format is 4:2:0.

I don't think rtings have much leverage with LG, they buy TV's personally to test then resell later, not sure if LG sends review samples to them.

The Forbes guy on the other hand has always been able to speak to high ups in LG and whenever he highlights a problem LG respond so he has connections there.

No Freesync support on the C9 is quite disappointing, that should be an option for PC users and if the device had been run through AMD's Freesync certification the HDMI VRR issues would have been caught before release to market.

This is what I was afraid of with HDMI group adopting adaptive sync tech like VRR, no testing of any kind  to catch problems (Samsung does run it's displays through AMD Freesync certification).

Come on LG for such premium high end TV's you gotta do more testing in this area.

(There's also the lack of any PCM 7.1 support over eARC, another oversight it can be made to work by hacking HDMI audioID & Xbox/Playstation both use PCM 7.1 for best audio quality and lowest latency)

SlimNebuloid

Update: they have responded in the discussion. They apologized for only testing the Xbox in SDR mode but they did include a link to the recent Forbes review that blew the story open publicly. The Forbes reviewer states that LG has informed him that they are aware and working on a fix. That’s good news at least. Let’s hope it comes sooner than later. Link here, link to Forbes review is contained within.

Btw, the discussion at rtings is gaining steam. Please continue to upvote it until they can’t ignore us anymore.

I’m certainly hoping for an update enabling backward compatibility otherwise there was no point in upgrading from the C8 so soon. Although I suppose the next TV I get in 3-4 years may be 8K depending on what the next gen systems support and how fast they can get the cost down. LG does have a history of fixing complaints but it might not be for a few months. It took them until December last year to fix the HDR scene transition delay bug didn’t it? 

divashenko

I still have another 8-10 days to return the TV. I'm hoping that there will be a solution or at least a message coming from LG in the next days but maybe I shouldn't hold my breath. Has anyone heard any feedback from their service request/concerns to customer service? 

As far as I understand, even in terms of connecting your PC, not even the 2080TI has HDMI 2.1, so will the C9/E9 be unable to use VRR/HDR until 

A) Firmware update if possible with current Xbox models
Next generation of gaming systems that have HDMI 2.1 
C) Next generation of graphics cards that have HDMI 2.1

? 

SlimNebuloid

That’s extremely shady. I guess it’s up to LG to make good on this now. Let’s see what happens I suppose.
