Pls Help Test Z9X with Oppo 203

Thanks. When I bought z9x pro I was kind of hoping that it would be THE player I need and no more ripping or demuxing or muxing any more. I still hope that you can cross test among your three devices sometime and let me know what you get out of it.

 

How do you have content library connected to media players? If a NAS or SMB you can use PLEX app on C9 itself to deliver content to it.
No perfect player out yet but wondering why the latest devices like the Pro wouldn't utilize the CMv4.0 delivery method and stick to 2.9?

 

I'm not sure what you mean in the long term. I was hoping to connect my HDDs to Zidoo and using it as a smb server and dlna server. But the new z9x pro has a samba bug right now and I need to wait for their new firmware to fix it.

 

Gotcha, I was just saying if you use a nas, you can share data onto the LG without having to plug in the drive to the tv every time over PLEX.

And yes, I am planning to get a working copy of No Time To Die as well and get it working with C9 and see what I find. Will keep you posted.

In the meantime, it is my plan to use Oppo for discs, Z9X for TV shows and streaming content with TrueHD audio and some foreign content with must have subs and C9 for everything else converted in a TS container. I have everything connected over PC's SMB so it makes it convenient to deliver data to all 3 machines simultaneously.

 

What is the issue with samba on the pro?

 

I could be wrong but doesn't cinema home have innacurate eotf tracking? Pretty sure that dolby vision game optimizer is universally sh** on by reviewers for being awful (it's very close to cinema home eotf). You have to basically calibrate dolby vision with hardware if you want an accurate DV gaming mode. If anything I said is wrong please let me know!

"Cinema is accurate , how DV is supposed to be.

Cinema Home is LG solution to boost the middle and low Gamma to give the Impression of more nits."

 

Works for me.

 

Moot point. We are not testing picture modes here, rather diff. devices using same picture modes on both.

From same thread you linked:
Cinema is slightly darker and meant for a blacked out room.
Cinema home is a fairly accurate preset but brighter in picture for a room with more ambient light.

 

Yes, moot point since we compared the same picture mode. More just my own curiosity. And I believe the comment I linked is the correct explanation. The comment you quoted is probably quoting LG's BS descriptions.

This thread explains that cinema home is inaccurate. Just for your awareness ha. Now back to the issue at hand!

 

I'd be very suspicious of any "mode" that wasn't either called "Standard" or implied standard settings unless I could control the colour profile, gamma and white point myself. I'd certainly steer clear of something called "Cinema" as that almost certainly will have been messed about with.

 

Classy Tech Calibrations has talked EXTENSIVELY about cinema home mode on LG OLEDs. They are completely innacurate. I suggest you watch the below video when he explains it in much greater detail than in the vidro you linked. I have no idea who made the video you linked and it is talking about an ancient OLED model. Cinema home is the same as "dynamic tone mapping" on HDR10.




@Markswift2003 i want to make sure I'm using the correct terms here. If cinema home is messing with gamma and brightness, would that be different "eotf" tracking?

Also there is no filmmaker DV mode on LG OLEDs. That's why cinema mode is considered the closest out of the box you'll get to accurate without calibration. There is also a standard mode so perhaps that is fine too. I'm not really sure. I usually go off this:l. It's mostly just a compilation of recommended settings (short of calibration) from hdtvtest/classy tech/avsforums, etc.

Its Darko who has been doing tv calibration since I can remember. And I posted this vid of the ancient OLED model because that is the model I have! Maybe the new TVs aren't accurate.

I dont know who this classy tech person is... but I watch the vid now.

 

Yea i mean at the end of the day there's definitely gonna be differences between reviewers and models, etc. And also who cares? You should use whatever you like better. I don't mean to impose my opinion on you. I apologize. But everything I've seen (at least on CX onward) shows cinema home mode essentially being dynamic toneapping forced on.

That classy tech guy knows his stuff, believe me.

 

All good, I know Cinema is the most accurate setting but the word inaccurate for Cinema Home is not what I'd use. It is simply adjusted for a bright room environment is all, sorta like Expert Room Bright and Expert Room Dark. It is tone mapping but with accuracy unlike HDR10 and selecting Dynamic Tone Mapping on top, that has horrible results. But yea this is a personal preference and slightly off topic but still good to discuss.

 

Yea. Perhaps we should make like an LG OLED thread here, since I'm sure A LOT of us own these OLED TVs. I'd love to chat more with you about LG OLEDs in the appropriate thread!

My original idea about how this relates to the Oppo issue is that perhaps the "dynamic tone mapping" in cinema home is reacting differently to external vs. internal players? I have no clue WHY that would be. But that is why I suggested repeating your tests with normal Cinema mode...just to rule out that weird circumstance. You never know when something wacky like that is responsible for PQ differences, ya know?

 

EOTF is Electro Optical Transfer Function - essentially it refers to in camera gamma where the optical luminance input of a camera sensor is converted to an electrical signal using a transfer function (graph) - for all intents and purposes, it's gamma, which is the luminance relationship between and input and an output signal split into its RGB components.

For simplicity the RGB components are often considered together so gamma can be considered as one transform rather than three.

For SDR we have traditional power gamma (2.2. 2.4 etc) but for HDR we use PQ gamma - Perceptual Quantiser - which allows for tone mapping - I'll try not to bore you with too many details - I could rattle on about this stuff for hours, but again, worth reading up on.

 

I have 1 question that I have not ever been able to figure out:

In the below example of a monitor review:



at the 17:50 mark, you see the two graphs? One is labeled EOTF and one says Luminance. What tone curve is the graph on the right using?

My confusion is that if you watch the below HDTVTest video:



On the same monitor, at 8:38, the 1000 nits graph looks identical to the right graph in the first video i posted above from monitors unboxed.

So when reviewers show luminance EOTF tracking, do they normally use a 1000 nit tone curve to demonstrate this?

@B0RN i made a thread for people to chat about LG OLEDs. Feel free to continue our convo there .
