Setting brightness to 49 gets rid of the flashing? I thought that was only for raised blacks? Im def not seeing raised blacks though
Yes 49 gets rid of the flickering as well in the letterboxes as well as raised blacks

For me I haven't any issue with the auto setting when gaming going directly to the tv itself. I cant speak on connected avr devices

But I hope you enjoyed the commentary and the surprise visit by D-Nice. I tried to touch on all the subjects that have been discussed on this thread and it was good to bring in D-Nice to talk about his experience and testing as well.
I don't know if anyone noticed this, (maybe not because I'm VERY sensitive to it), but I noticed that the Sony had considerably more of a 3d depth than the LG. My brain could actually calculate the distance of things in the background, whereas with the LG, I could not. (If this was brought up in the video and I missed it, please no worries).

It's sort of like the difference between closing one eye while viewing your tv or this youtube video and watching with both eyes open.

Having said this, I actually prefer this flatter look for film based material. I've noticed that when a tv exhibits this sort of depth, it will retain this characteristic no matter the viewing application. It's great for sports and real life viewing. But for me, it "competes" with the flatter look of film that I so desperately try to maintain.

As the tech keeps changing, I often feel that it is a "losing" battle.
When confronted with the choice between two tvs, and one looks more "impressive", I have to stop and really weigh the pros and cons.

Again, I'm VERY sensitive to depth. As I have said before, I have noticed changes in my tvs depth when activating a setting that has nothing to do with it. Most people on these thread do not notice this. From personal experience, when I show such things to friends I have over, most will see NO change while a few will find it quite OBVIOUS. Because of this, I have "learned" to "forgo" talking about such things most of the time on here because those who can't perceive depth in this way actually find it all quite ABSURD. But I have concluded that depth perception for humans runs along a continuum between those who have this sensitivity and those who do not.

Anyway, that was the main difference that jumped out to me regarding these two tvs while watching this video. It was interesting how, even with it all being processed and going through youtube, it was still quite obvious - to me.

That 3d depth look is exactly the best way I can describe the picture on the cx when I compared it to the c9s I've had. I just couldn't figure out the word for it lol

ABSOLUTELY!

I don't own the CX, but that was the FIRST thing I also noticed between these two sets as well.
Very life-like and breathtaking.

Over the years I've noticed tv tech going in this direction. The latest offerings by Sony and LG really demonstrate this.

So we are really going to make comparisons and pass judgement off a video via you-tube downloading to a PC or some other device with God only knows has what settings and/or other processing. Judge for yourself, people still have trouble admitting the Lucky Goldstar makes videophile displays. You know things are crazy when the Vizo fanboys start venturing into the OLED threads

The Xbox is connected directly to HDMI 3 on the CX so that VRR and all other video enhancements can be enabled, and the Vertex2 is connected to HDMI 2.

The Vertex2 isn't cheap ($400), but it will do what you want, and it effectively gives any HDMI-compatible receiver eARC functionality. The firmware is updated regularly and the developers are very responsive. I imagine they'll be releasing an HDMI 2.1 version at some point in the future.

As others have also testified, it is possible to send audio to your receiver from your PC via either your graphics card (using a DisplayPort to HDMI adapter if necessary) or from your CPU's integrated graphics HDMI port. That way you'll get G-Sync on the CX and optimal sound from your receiver (up to and including Atmos).
Do you know if there's a cheaper solution for just passing through HD audio and MC-LPCM to a non-eARC AVR? I don't need the video scaling that this device does, and wasn't clear their other products fit my needs.

So other than using your TV as a computer monitor, for computer games, and console gaming - what advantages does HDMI 2.1 have for the non-computer user/gamer...

Shopping List:
TV: LG CX/GX; Samsung Q90T/Q800T...?
Blu-ray: Panasonic UB820
AVR/Pre-pro: Marantz 8805/7705 or 8012, or Yamaha 5200 or 3080
Speakers: GE Triton One.R, or ML ElectroMotion ESL X

Is this raised black problem some users mention on these sets only limited to dolby vision, or does it also affect hdr10? Most of my hdr viewing is hdr10, does hdr10 look right with brightness set to 50?

Well the premise is that an HDMI 2.1 TV can pass lossless bitstream audio or 7.1 PCM out over eARC presuming you want to use your TV as a media center instead of an AVR/Prepro (my choice) or perhaps a soundbar.

Maybe someday, TV internal apps will be able to stream lossless bitstream audio or 7.1 PCM as well but that's dependent on internet bandwidth, streaming server capabilities, and data caps.

However, if DTS isn't supported by the big TV manufacturers, then HDMI 2.1 becomes more limited as a media center.

For me not being a gamer, HDMI 2.1 is a future checkbox should it eventually evolve into something that I need.

But you dont need a hdmi 2.1 tv for eARC specifically, eARC is not a very high bandwidth feature (~36.8 mbps), so it is able to be implemented on tv's with a hdmi 2.0 18gbps chipset.

AIUI, eARC functionality is only available with HDMI 2.1. Never claimed you needed 48Gbps or even 40Gbps (e.g. LG) to support lossless MCH audio.

EDIT: If an 18Gbps HDMI 2.0 chipset can support eARC, then based on how HDMI.org allows for their loosie-goosie marketing, then I suppose it could be marketed as offering HDMI 2.1 features (i,e, eARC).

In speaking with LG today the 2020 LG OLEDs do not have the raised black HDR issue related to replacing the 1DLUT like the 2019 sets. If you are seeing it then check the calibration.

eARC is a part of the hdmi 2.1 specification, but due to its relatively low bandwidth, it can be implemented on hdmi 2.0 tv's with 18gbps chipsets, that was the point. several tv's have eARC, my sony a9g has it. im not getting into the marketing aspect of how they 'could' label those tv's.

I've read elsewhere on these forums that the shArc from thenaudio works well:

https://thenaudio.com

mitchmalibu posted about it first in the 2019 LG gaming thread (https://www.avsforum.com/forum/40-ol...l#post59623834) and there are some follow-up posts confirming that it does the job. $149 on amazon. Not cheap, but less than half the price of the Vertex2.

Is this good or bad news for owners of 2019 LG OLEDs? Does this mean that LG at least knows what the underlying problem is?

I did not pay additional warranty when I got the C9 (I just paid for the TV, no extra plans or anything). I don't know under what they were handling it; I just called and told them I was getting a high pitch noise coming from the back of the TV, and they offered a replacement right away. This is ONE store, though. Probably non-representative of Best Buy as a whole, but hopefully.

Thanks. My experience with my local BB/Magnolia has always been positive.

I've read elsewhere on these forums that the shArc from thenaudio works well:

https://thenaudio.com

mitchmalibu posted about it first in the 2019 LG gaming thread (https://www.avsforum.com/forum/40-ol...l#post59623834) and there are some follow-up posts confirming that it does the job. $149 on amazon. Not cheap, but less than half the price of the Vertex2.
This is amazing. Thanks I'll check it out!

Enabling Dynamic Tone Mapping will help to brighten dark scenes as well.
Don't forget to turn off Peak Brightness in the settings if you are watching SDR.
Also, you can try increasing OLED Light to increase the bright scene brightness.
Disable Dynamic Contrast too.
How do you enable dynamic tone mapping on the CX?

But Vizio is supposed to have their own OLED model soon.

Yes, eARC is a HDMI 2.1 feature but does not require an HDMI 2.1 FRL port, 48Gbps or otherwise, to operate. It uses another set of wires in the HDMI cable. Because of this it does not take up any of the bandwidth used by the HDMI video signal.

But I hope you enjoyed the commentary and the surprise visit by D-Nice. I tried to touch on all the subjects that have been discussed on this thread and it was good to bring in D-Nice to talk about his experience and testing as well.
Just looked to me like classic tinting that often plagues many of these OLED panels to some degree or another, regardless of branding/implementation. no...?

I actually prefer using my fire tv cube gen 2, because the apps have less color banding and it seems to give slightly better performance than the on board apps.
