    Thanks Mark I appreciate you taking the time to test my EDID.

    Ah right - Auto is generally the right choice for most situations but options available will vary from display to display depending what the EDID says.

    Auto will always chose the "correct" mode to match the content but then it is up to the user to decide if they want to force other modes. There's no real way to generalise this choice as it depends on EDID and the user's setup.

    Thanks Mark,

    For a lamda user who is not interested in what an EDID is for and everything else...then the best choice will be the AUTO mode.

    I ask this because a lot of buyers like it when it's simple and they don't have to spend an hour in the settings to see if the color is slightly different.

    Of course there are also those who like to have as many options as possible to get the best possible image :)

    Yes, absolutely - and that's why I put Auto in the first post.

    It's only rabid test freaks like me (and a few others!) who like to push as hard as we can to see what we can break ;)

    Yes, of course, it was just to confirm in person :)

    Right here's what I figured out.

    Your TV supports 4K60 at 600MHz in SDR and HDR absolutely fine (EDID report attached) but there are restrictions in the Dolby Block.

    It is Standard DV only and does not support 4K60 in DV - the Dolby Block decodes as below:

    DV Version: 1, [long 15-byte version]
    DV DM Version: v3.x
    DV Interface: standard DV only

    2160p60: not supported
    YUV422 12bit: not supported
    Global Dimming: not supported
    Backlight Control: not supported
    RED Primary: 0.676, 0.320
    GREEN Primary: 0.266, 0.660
    BLUE Primary: 0.137, 0.047
    MAX/MIN Luminance: 700 / 0.001 nits


    This explains why 4K60 isn't supported.

    But to get everything working properly, you need to go to Settings/Display/Dolby Vision Compatible Mode and set it to "Priority Standard DV"

    Once you've done that DV content should play correctly and you can change resolution and frame rate whether you're in HDR Auto or Dolby Vision VS10 Engine.

    Thanks for the report Mark,

    I know 4k 60 Dolby Vision and LLDV is not supported on the 2016 series. This is why I was asking for proper Dolby Vision Standard to be added to the Z9x since launch, only 1080p 60 DV standard would work up until firmware 0.90 anything above 1080p 60 was LLDV. The Z9X didnt support other standard modes.
    I have been using Priority standard since it was introduced in 0.90 which finally allowed 4k 30 DV for the GUI and when watching movies it would output 4k 24p DV just fine on my TV. I was watching many films and shows without issue.

    The problem now is since 0.97 4k30 DV standard and 4k 24p is broken on the LG C6 and gives a black screen with the proper settings. ie-Settings/Display/Dolby Vision Compatible Mode and set it to "Priority Standard DV"

    There's something odd going on here...

    So you say you can't change resolution to 4K23, 4K24 or 4K30 - now that's something I saw too earlier using your EDID. Also you say you 4K24 content plays at 60Hz. Again, that's something I saw earlier too.

    Now those two symptoms are indicative of the box throwing a wobbly which is something I see a lot because I muck around with settings I probably shouldn't do - changing stuff on the fly that shouldn't be changed on the fly etc.

    Thing is I can't duplicate that now without changing Compatibility Mode to LLDV.

    If I do that then all sorts of freaky things happen:

    The GUI is at 4K30 and can't be changed

    4K24 DV plays at 1080p60

    4K23 DV plays at 1080p23

    4K23 HDR plays at 1080p23

    If I then change compatibility mode back to Standard DV:

    The Gui defaults to 4K30 but I can change to 4K23/24/25/30.

    4K24 and 4K24 movies play at the correct resolution and frame rate while 4K60 plays at 1080P60 (frame rate is preserved over resolution).


    One thing I did do was to set HDR to Auto in between changing compatibility mode so the Realtek engine is used and this presumably resets the VS10 engine.

    I think this might be a case of the SOC getting it's knickers in a twist.

    So try this:

    1. Set HDR to Auto
    2. Set Compatibility Mode to LLDV
    3. Set HDR to VS10
    4. Set HDR to Auto
    5. Set Compatibility Mode to Standard DV
    6. Set HDR to VS10

    You should then have the gui in 4K30 and be able to play 4K23/24/25/30 correctly and 4K50/60 will output as 2K50/60.

    You should also be able to set the gui resolution up to and including 4K30.

    The big clue is the fact that resolution doesn't change which indicates something in the box locking up rather than an issue with the TV.

    On new firmware for the first 19 or so tries of a DV file the DV logo on TV shows but it's black screen. When the stars align on the 20th or so try the video plays back in 24p DV and continues with no issue till the end. Issue then repeats on next file. During those tries it will sometimes output as SDR also when it fails to even start DV but at least I can see that :).

    Haha - had some more thoughts above!

    Yes firstly I need to clarify I have no issues with HDR, SDR 4K 24p switching VS10 HDR to DV conversion at 24p all of that works normally.

    The issue is exclusive to Dolby Vision content and Dolby Vision standard mode which includes VS10 on GUI. I can't tell if my DV content is trying to play at 4K60 because the black screen doesn't allow overlay and TV won't show refresh. I do know that if I set Priorty LLDV it performs the same buggy way as Standard priotity so yes I would say it's ignoring standard toggle and trying to output LLDV.

    I will try your approach I am also noticing so much weirdness with settings like for example. I am in Auto mode so it should just switch to DV or HDR SDR as needed but

    Colour Settings 4k 23-30Hz
    If I set certain modes like YUV444 8BIT it will try to output DV but I get black screen.
    If I change it to RGB444 8BIT it will output as SDR.
    This behavour is consistent some of the 10 bit and 12 bit modes try to output DV others go to SDR.


    1. Set HDR to Auto
    2. Set Compatibility Mode to LLDV
    3. Set HDR to VS10

    Black Screens Here. Should go to 1080p 60. (TV Shows it is 1080p DV)

    4. Set HDR to Auto
    5. Set Compatibility Mode to Standard DV
    6. Set HDR to VS10

    So even if it black screens at that point, just click <down> 3 times then <enter> and that should get you to Auto.

    Managed to get through the procedure even with black screen on step 3 but the GUI is still buggy with black screens like in my video. Info button says it's 2160p30 RGB 8bits and TV says 2160p DV which is correct.

    Thanks for your suggestions I will try playing with settings again in different orders over the next few days. I fear it can only be fixed with firmware though and the developers can't seem to reproduce the problem so it might be specific to 2016 Dolby Vision TV's.

    Hello again!
    have a question: if i stay 1)vs10 for hdr (hdr setup) and standard dv(compatible on) or 2)lldv for all (hdr setup) and standard dv(compatible on)is it correct ? or i must stay lldv(compatible off).
    is it correct to have lldv from vs10 and then use standard mode, but not lldv? is there any difference? have no questions for native dv content(use standard),only for hdr to dv
    Thanks

    If you set LLDV for all then the compatibility Mode has no affect so it doesn't matter which you set.

    For other HDR modes, when you output Dolby Vision, you can choose whichever Compatibility Mode you prefer.

    So if you set Compatibility Mode to Standard, you will get standard DV from "Dolby Vision VS10 Engine" and "Dolby Vision VS10 Engine for HDR" and LLDV for "Dolby Vision Low Latency (LLDV....)" assuming your TV supports Standard DV and LLDV

    If your TV is LLDV only (Sony) then set Compatibility Mode to LLDV.

    Thank you for your help and support!;)
    As i understood, black levels will be ok in Dolby Vision VS10 Engine for HDR and Dolby Vision Low Latency (LLDV....) too (if we have dv display),yes?

    Why don't you add a new chapter for "Optimized Audio output" using an AMP or Sound-bar.
