Having a discussion about what you prefer is fine, but it is an endless discussion which I refuse to take part in. I have zero interest in what other people's personal viewing preferences are, or how they came to those preferences. They are personal to all of us.
True, no one else except a few visitors are coming into your house. Pick whats best for you and call it a day......

Yes. But this applies to the C9 and CX. Downside is that you see more banding as all extra processing is shut off.

There was no mention of 4:4:4 at the beginning.

Thanks for the reply and the link to the other post, but still not sure what he means. At around 9:50 he says PC mode doesn't have to be engaged to get full chroma. I've never heard anything other than 444 referred to as full chroma.

"alternative white point". This is a big topic. It's a way of calibrating such that the white looks more like the D65 white you'd get from another "reference" display like a CRT or a plasma. Because of the effect of Metamerism (google it) and the narrow bandwidth of R,G,B,W light coming off the subpixels of an OLED, it means that even if you had the most accurate calibration in the world, and the measurements proved it was a perfect D65, to your human eyes it would still "look" wrong. An Alternative White Point is a bit like an "offset", to bring the whole calibration back to looking like a perfect D65 on a Plasma would look.

Different display technologies both being perfectly calibrated, yet looking different to the eye when you put them next to each other, is a bit mind-boggling. It's down to the way the eyes is tricked into thinking that mixtures of RGB are colours, when they are not really. Your eyes only ever see 3 colours coming off the screen (4 if it's a WOLED).

Ha of course! My C9 using a AWP just didn't recognize the acronym. What do you think about using those settings on a C9?

Anyone knows if its intentional on the CX that sharpness has no effect for HDR and DV content but works fine with SDR content ?

Does anyone know how to display the current refresh rate? When I click on the display information (using the ellipses button), I only get current resolution and audio format. Sometimes it feels like the refresh rate switching isn't working properly on my Shield.

Vincent's measurements and verbal explanation about the differences between the C9 and CX are meaningful. I also realize that attempting to make generalizations and conclusions from the "visual" comparison between the to tvs, given they are going through youtube are meaningless.

Having said this, I wanted to share something I did notice after rewatching his video that was consistent with every side by side comparison.

The CX "appears" to be more DIMENSIONAL looking in every side by side image. For example, if you look at Matt Dameon on Mars in his space suit, there is an unmistakable 3D dimensionality to it. IF people are seeing this in front on their CX's, I would say that the look is very compelling.

I'm a severe film traditionalist, and yet, I acknowledge that film, it's look, and tv tech is evolving. Very few movies are even made with film anymore. But I confess that, while the CX images don't have as much of a flat film-look, they look really, really nice.

I also consistently noticed that, while the C9's images were brighter, the CX's images appeared a bit more balanced. The C9 looked ever so slightly washed out in comparison. (Again, I realize that youtube's processing and limitations are in complete control of what I'm observing.)

This for me is the big positive take away from the CX. The tv "appears" to have a look that draws or pulls me into what i'm viewing. Conversely, the brightness of my C9 projects in such a way that it too grabs my attention in a cinematic way.

I DO prefer the brightness and less aggressive ABL of the C9, but the CX is offering it's own set of "wonderment".

Of course, I'm not sure what the real-life "take-away" is here.
I don't know if you dual C9 / CX owners can confirm any of this, thus making it credible.

Curious.

I said a lot of this when i first got my CX when everyone was saying, no, it's just a C9 with BFI motion processing. I'm glad Vincent confirmed a lot of what we saw when we got these sets about a month ago.

I've seen your post in the other thread. My opinion is that you shouldn't. It's a different model. Copy the safe stuff (not the white balance) if you like.

Sadly, you can't display the current refresh rate on that option. Same problem on my 2018 C8. It saddens me that they won't improve this. Even my old crappy Samsung showed the refresh rate of the incoming signal, and whether it was interlaced or not.

Go to the 3rd menu channels and press 5 times 11111 which will give you the HDMI menu . Its explained in the first post here

You beat me to that before I could add that tip to my post. How I wish the C8 had that HDMI info page, but it doesn't .

Yes. But I don't recall him talking about either this dimensionality or the more balanced brightness that I noticed on the CX.

Matt Dameon in his space suit on Mars that I was mentioning - Vincent put this up for the sole purpose to show the difference in smooth gradiation between the sets. But as I was watching this, the dimensionality (whether real or youtube distorted), was screaming at me. Also, the luminosity of every CX slide "appeared" more balanced, providing a richer, more focused look.

IF I'm correct, there are more advancements on these sets than is even being discussed by some reviewers or being acknowledged beyond the con/pro - 48/40, BFI, 120, motion improvements, pixel variation, ABL, brightness, upscaling, etc.
(I probably simply missed some posts that have already independently discussed what I have noticed with an actual accurate frame of reference. Based on your response to my post, it is clear that I need to go back and re-read your earlier posts about this jrref. I look forward to it).

Without Vincent speaking to this and without me having an actual CX in front of me, my youtube observations are quite meaningless. But the consistency of what I was observing did compel me to point this out and inquire about it.

Can you confirm/refute adjust the two things I am seeing on this mirage called youtube? Very curious. (Thanks in advance).

Jjrref any new updates or opinions on the beta firmware. Still on the c9 vs cx debate, im a gamer and it sounds like the c9 is the safer purchase. But a visible difference in pq might sway people in my same boat. I also hope the hdr brightness in the cx being lower is moreso because of panel differences. But its surprising that both HDTV and rtings reported the same findings.

I hear there’s going to be an update for the Cx/GX in June that improves HDR. Does anyone know anything about this? I’m new to all this - where would I go to keep abreast of firmware updates and what they do? I understand it’s a bit of a minefield as occasionally firmware is released that can downgrade the image of a TV..

My 4-year old C6 can still beat any new model in "3D dimensionality". I just need to put on my 3D glasses.

Thanks, a bit weird that it's hidden so deeply, especially for a TV touted for film enthusiasts. I'm also used to my previous Samsung making this info available in the normal input information screen (just press OK).

Was really looking forward to using the 48” model as a computer monitor but not being able to select 12 bit @4K 120Hz is disappointing for us PC gamers.

Perhaps next year we’ll see an actual improvement to the C9 model.

What is correct aspect ratio and just scan setting? I can’t find or tell the difference between 16x9 or original. 16x9 was default. And just scan I’ve always left on for all my TVs no matter the manufacturer term to turn overscan off but somewhere I read mentioned it’s recommended to turn just scan off. That zooms in and enables overscan though and I always was under the impression that’s bad. I’ve never seen noise on the edges and I like to see the whole picture and not zoomed in.

Original or 16:9 with just scan on.

I prefer to use original as then you get the correct aspect ratio for older TV shows in 4:3.

The 3D LG OLED is something I regret missing.
I own many 3D movies. Most are only available in Europe now and are region free. So I buy imports.

I have Panasonic plasma tvs that are great with motion and the 3D looks great, but the brightness of the OLED with 3D must be really nice. Samsung 3D hurt my eyes and movie theatre 3D was too blurry. No comparison to how it looks on my plasma.

Are they all curved? How many years were they made? Active or passive 3D? 4K tvs?

When Sony came out with their first 4k tv, it was 3D. 4k was supposed to transform 3D by providing full 1080 resolution without the need for lower res interlaced video with passive glasses or darker active glasses.
But (sigh), we know how that all turned out . . .

I understand it’s a bit of a minefield as occasionally firmware is released that can downgrade the image of a TV..
You can 'enable' test\beta Firmware through Service Menu but I strongly advice against it! You can no longer roll back to previous firmware. You can get stuck on a beta firmware which has higher version number than public firmware (you can install a firmware with higher version number only) .Even if the beta is older it might have a higher number version and you will not be able to install new public firmware with lower version number until LG releases a public FW with higher number.

There are no change logs for Beta Firmware so you can't know what is changed but you can read reports from those who installed them (although I saw someone managed to extract Change log from C9 beta firmware, I wonder how?)


I am stuck on my previous 65C8 with a Beta firmware and already missed 2 public firmware updates which are newer with important fixes .

So better stay away from test firmware

I hope people heed your advice. I fear that they won't. If they don't, they are stupid.

I bet some newbie with only a few posts will come along, and wrongly tell people the Pure app lets you downgrade. That hasn't worked for a year.
