D-Nice, is this comment specific to motion handling in general of the CX in comparison to the C9 and A9G or specifically with respect to using TruMotion?

jrref, are you seeing improvements in motion in all content? I don't game a lot and mostly watch movies by HD DVD through an Xbox or Apple TV or cable/xfinnity. I also watch a lot of Sports programming over cable. So is the motion improvement you are seeing mostly when watching movies shot in 24FPS or does it translate to general broadcast TV over cable (also is the upscaling on the CX improved over the CP for broadcast TV?) Thanks.

thanks jrref, not a gamer so there's that :-) Already got the bigger screen at 77 so I think I'll just enjoy my C9 and stay away from the CX Owners thread so I don't get tempted.

I did quite a bit of comparisons between the C9, CX and A9G via SDR, HDR and DV yesterday. If you already have a C9, I see no reason to pay extra money for the CX.

Yes, the additional BFI modes are cool. However, if you every get it calibrated, it must be done with the particular BFI mode engaged and if you switch to another BFI setting, or want to turn it off, you need a calibration for that. The motion difference between the CX and C9 are incremental.... incremental in the sense that you will be very hard pressed to see the difference when explicitly looking for differences instead of enjoying displayed content.

That post was specific to the TruMotion setting. In general, and comparing the CX to the C9, the motion delta is incremental.

I’m curious about motion handling for 24hz material with the cx. I had a 77” c9 returned last months since I couldnt accept how 24hz looked. (In all other aspects I thought the image was amazing)

How would you guys rate:

C9 vs AG9 vs CX (??)

...with motion handling for 24hz material. (Its a shame my 10 year old pioneer is far superior in this regard - Im aware of the sample and hold dilema)

Cinema Clear uses no BFI - it adaptively tries to adjust the de-judder/de-blur based on the content while trying to not introduce SOE.

The BFI setting is called "OLED Motion Pro" (it's under the User setting in TruMotion).

I think Cinema Clear works pretty good. Not perfect but I like it. It made the difference for me.

Got my 55 delivered today from Best Buy and its very apparent it handles motion better than my C8.

However, what settings are you guys using for Dolby Vision?

Cinema Home looks the best but not being able to turn off TruMotion is gonna drive me nuts.

Cinema seems like its extremely dim to the point I lose shadow detail....

How can I match the picture on Cinema with Cinema Home without TruMotion?

I can relate, it was only a year and a half ago that I bought the C8 on sale and did a CITI price rewind on it. I wanted a 77", but those were definitely out of budget for me at the time. Hopefully that wont be the case this fall, with its lesser MSRP already.


Get the bigger TV if its in your budget.

Hey AVS,

Preface: I have a C8 in the living room for TV and movies, but I am interested in getting a C9/CX for my PC. I have a 2080ti, but Ill probably end up having to get the 3080ti for HDMI 2.1

Now, my question is...I wanted to get the CX because it gives me the option to do 4k/120hz with chroma subsampling NOW and have full bandwidth 4k/120hz later. For those of you who've used this, how BAD does chroma subsampling 4k/120 look?


Thanks

You can not. Cinema is the most accurate mode on the CX. Cinema Home boosts the mode tones which means it does not follow the EOTF (PQ).

Disable AI stuff under General tab, after that you can turn off TruMotion.

Very different impressions from jrref and D-Nice about the CX so far. Only real agreement seems to be that brightness is heavily diminished the higher BFI setting you use, which is not good.

We're going to need to wait and see many different expert reviews and testings before knowing if the CX is worth the purchase.

And until Sony releases its new chip in the A9H, we won't know how much better motion and upscale processing will be in 2020.

For now, it's safe to say that only gamers might benefit a very negligible amount with the CX over the C9.

We can only give our opinions because the technology in these sets has pretty much reached a limit with the current panel. For me personally, this is the first LG that has motion to a point where i can watch it since I’m very sensitive to this. So it’s best to look at the set yourself to see if the upgrade is worth it to you.

Also if we see more sets as good as the ones D-nice and I have meaning virtually no banding and tinting, that alone is worth the upgrade because as everyone knows we saw an unusually higher number of sets last year with banding and severe tinting.

But I do agree, as I believe some said last year going from a C8 to a C9, if you have a C9, unless you are going to a larger screen size or you are really sensitive to motion, a gamer, or if the panels hold up and you want a cleaner panel, you probably won’t need to upgrade.

Definitely understood and your impressions are much appreciated as always. Agreed that until panel changes are made (if in fact they ever are), this is pretty much the peak of OLED since there's very little headroom left tech wise. Outside of LG Display trying to improve its efficiency and QC on panel manufacturing, it's pretty much just about their customers trying to perfect processing and gaming features at this point.

What are your thoughts so far on the "high" BFI setting? Does it appear to improve motion clarity beyond BFI on current OLEDs? Similar amount of flickering?

It looks fine, loosing HDR sucks though. Playing GTA4 right now [email protected], amazing stuff. Last time I touched this game was during xbox360 times.

Does anyone think it would be an appreciable difference between this and my A1E? Been very happy with it but you know how it goes. Would honestly probably wait to see what Sony announced to replace the A9G but the CX seems mighty attractive for the price.

I plan to upgrade mine for the gaming features. Sony has been strangely lacking when it comes to the gaming features of their tvs

How is dolby vision performance on this tv compared to C9, when using the more accurate Cinema preset? On another forum, I was reading DV in Cinema looks slightly less bright on the CX than the C9. Anyone care to confirm?

DV looks almost the same to me as far as brightness or maybe a tad brighter than the C9. I had the c9 for a while so I got a good feel for comparing the two. The one thing that lg still hasn't fixed is the elevated blacks on hdr and now on the CX wit DV. I noticed it instantly on the internal Netflix app that DV has bad elevated blacks and u have to turn brightness down to 49 on both hdr and dv. On the c9 I didnt have issues wit DV it was only HDR where I had to turn brightness down to 49 hopefully finally it will get addressed by LG because its ridiculous right now. Other than that the CX so far for me has been solid

If you drop the refresh rate to 100Hz but retain the 3840x2160 resolution, are you able to then increase the chroma resolution to 4:2:2, or more realistically increase the bitdepth to 10bit?

In particular, I'm wondering if it'd let you enable HDR10...


Also I don't suppose the TV is natively capable of inputs running at 3840x1600 and 2880x2160 without the use of GPU scaling as alternative "cheaty" ways to decrease bandwidth and therefore possibly allowing you to increase the chroma and/or bitdepth?

Do keep in mind that the XB1/PS4 have single-threaded CPU performance comparable to a 17 year old high-end CPU or 14 year-old mid-range CPU (~2GHz Athlon 64) and multi-threaded performance comparable to a 12-year old high-end CPU (~3GHz 4c/8t Nehalem).

The XBSX/PS5 by comparison have CPU that's almost identical to the Ryzen 3700X which is relatively high-end ~$300 CPU that launched only 9 months ago and easily has 4x the single-threaded performance before any manual optimization due to the combination of having 2x the clockrate and 2x the IPC, and multithreaded-wise these are 8core/16thread CPUs rather than the plain-old 8core/8thread CPUs in the XB1/PS4.

One key point to consider is IPC aka "performance per clock". At the time when the XB1/PS4 launched, the then-fastest CPU architecture (Haswell) had IPC that was around 1.75x faster than the CPU architecture found in the XB1/PS4 (Jaguar). But as of this moment, the CPU architecture found in both the Ryzen 3700X and the XBSX/PS5 (Zen2) has the greatest IPC of any desktop CPU to date (though by the time the consoles launch, Zen3 will likely be available on the PC which is going to farther improve IPC by some currently unknown amount, and that's without considering Intel's mobile-only Ice Lake CPUs).

The only CPUs on PC that are faster than the 3700X are because they either have higher clocks, more cores, or a combination of both - and neither are really options at the time for consoles since they'd eat too much into the power budget or would require having twice as many CPU cores which would blow up the die size and make things overly expensive (the Zen2 architecture requires that cores come in sets of 8, so if you wanted 12 cores you have to physically include 16 and then disable 4 of them).

They're both confirmed to support VRR up to 120Hz which is important as, the higher your maximum display refresh is, the better chance of support for LFC you have, and on AMD GPUs LFC is done on the GPU side rather than the display side - all you need is a refresh rate range where the maximum is greater than 2x that of the minimum (and since the minimum is typically somewhere between 30 and 48Hz, a 60Hz max simply doesn't cut it).

Also this means that a game is allowed to go over 60Hz without being capped to 60Hz - even if it means it only makes it to like 65Hz. And remember that the alternatives to VRR are tearing (ugly) or vsync (hurts input lag), so if your display can do VRR up to 120Hz then you might as well support it even if your game can only hit something like 65fps.

Alternatively the availability of LFC means that you're not forced to choose between capped solid 30fps and uncapped 60fps target for more demanding games - you can now run at something like 45fps without it being an absolute juddery mess even if the display's VVR minimum is 48Hz just as long as the VRR maximum is greater than 96Hz.

It may not be "good" but it's the laws of physics. The more black you insert, the less light comes out. I'm confused as to why you write "not good" as if this is coming as a surprise to you

We're going to need to wait and see many different expert reviews and testings before knowing if the CX is worth the purchase.
Yes, agreed. And everyone should definitely do this anyway. To rush out and make such a major purchase without carefully weight it up is reckless IMHO.

For now, it's safe to say that only gamers might benefit a very negligible amount with the CX over the C9.
Don't really agree with this part, but it's a matter of opinion both ways. On the calibration side of things, there are some very worthwhile improvements over the C9. There could be plenty of people other than gamers who would benefit. But - this is IMHO. As well as the build quality side of things

ps. There was an unexplained TLA in a post above which I found very frustrating. It might be common for gamers, but it's not common outside and really should be expanded at least once if it's used in a post please if you remember

Low Framerate Compensation (LFC)
LFC is an exciting new feature of Radeon Software that effectively extends the refresh rate range of many AMD FreeSync™ displays, enabling pristinely smooth gaming down to 30 FPS or less.
Nice picture on this page too:

So cinema is 100% like Filmmaker mode on CX? As that is touted to be the most accurate one with 100 nits and no truemotion.

Yes this is what I was hoping for! It’s a shame that all the local shops in Sweden keep insisting on displaying promotion videos, don’t want all the mess with transport back and forth with a screen that size again...

I keep hearing the A9G is supposed to be much better with 24hz, to be able to use the tv as center speaker would also be a plus for me.
