Recommended Settings and other useful stuff for RTD1619 Players

A lot of people ask about these, so I thought I'd post here so I can point to this in future.

Might not be suitable for everyone, but these are the settings I recommend from 2K & 4K viewing on the new Zidoo models:

MAIN SETTINGS

Playback/Automatic frame rate/Frame rate mode: Switch frame rate and resolution

Display/HDR: Auto *
Display/Color Settings/4K 50~60Hz: Priority YUV420 10BIT
Display/Color Settings/4K 23~30Hz: Priority YUV444 10BIT
Display/Color Settings/Non-4K: Priority YUV444 8BIT
Display/Color Settings/HDMI Range: 16-235 **
Display/HDMI Mode: 3840x2160p 23Hz ***

Audio/HDMI Audio: RAW
Audio/Downmix HD Audio output: OFF


*  Can be set discretely - available options are EDID dependent see below.
**   This sets 64 - 940 for 10-bit content. Can be set for Auto but I prefer to set discretely
*** This is personal preference and assuming auto framerate/resolution is on, it is only the gui setting.
   (Set this last since changing HDR mode resets HDMI Mode)

OTHER SETTINGS

Display/MaxCLL and MaxFALL: ON ****
Display/Colour Settings/Deep Colour Compatibility Mode: OFF *****


****   Some systems use MaxFALL/CCL, some don't. Generally leaving ON is fine because even if the system ignores it, there's no issue with the SEI message containing it. Can be useful to turn off for outboard gamma processing.

*****  Enables forcing of 4K50/60 4:2:0 10/12-bit even if EDID does not allow.
(Some TVs can accept this signal even though EDID says it can't)
If your EDID does specify 4K50/60 4:2:0 10/12-bit this setting will have no effect.
If your EDID does not specify 4K50/60 4:2:0 10/12-bit and does not allow it, setting ON will cause picture loss.


HDR SETTINGS FROM v6.0.50

Available settings will depend on EDID

​

DOLBY VISION COMPATIBILITY MODE (v6.0.90 onwards)

Display/Dolby vision compatible mode/<on><off>

This allows displays that can process both Standard DV and LLDV to prioritise which mode is used with DV output.

<ON> - Standard DV is prioritised
<OFF> - LLDV is prioritised


DOLBY VISION MKV COMPATIBILITY

The table below shows the expected outputs for different Dolby Vision Profiles of the VS10 engine.
Output of DV or LLDV is EDID dependent and all tests were made with Level 6 files (4K23)




LEGAL HDMI MODES

For information, below is a table detailing legal HDMI modes at 4K for both HDMI 1.4 and 2.*
The numbers show the bitrate, ie. bandwidth required, for each mode. Where it shows "--", it is not legal mode and therefore not supported by HDMI.




HDFURY VERTEX SETTINGS FOR LLDV

For those with a Vertex or similar and an HDR TV who wish to try the LLDV trick, Attached is a quick and dirty PDF to show how to set this up.

This fools the Zidoo into thinking it's connected to a TV capable of LLDV but remaps the colour primaries into BT.2020 allowing it to be viewed correctly with standard HDR settings.

​

 

Why not 12-bit?

 

You really want HDR10 to output in 10 bit as that is native, if the box then needs 12 bit for DV it should still switch to 12bit.

 

Hi Mark, any chance you can expand this and explain correct settings / when you should use Max / Fall CLL and Deep Colour compatibility mode?

 

Will do

 

Hi Mark, sorry to mother but can you confirm something?

I play a Dolby Vision MKV created from a MEL title.

If my Z9X is set to Auto in the HDR settings this file triggers DV and plays at YUV 12bit 4:2:2 Dolby Vision - is the player doing the Dolby Vision Decoding and sending to the TV?

If my Z9X is set to VS10, this file triggers DV on my TV but the output shows as 8bit RGB HDR - is the player tunnelling the Dolby Vision to the TV so the TV can do the processing?

If so is this correct behaviour, it seems back to front in my mind?

Thank you.

 

No probs!

Your TV (C9 I think?) plays standard DV and LLDV so what's happening is in "Auto" it's playing in 12-bit 422 LLDV by preference and in VS10 it's playing in 8-bit RGB tunnelled DV ( in VS10, it also forces that mode on all content and the gui).

If you choose "LLDV" in HDR settings, that will do the same as "Auto" for DV content but also forces LLDV for all other content and the gui too.

If I load the C9 EDID and play a dvhe.07.06 BL+MEL+RPU file, this is what I get too:

HDR "Auto" - 12-bit 422 LLDV
HDR "VS10" - 8-bit RGB DV

The info screen on the Zidoo is very limited and should generally be ignored - as I've said a million times (no exageration!) this is where an HDFury device is invaluable so you can see exactly what's going on.

Where your TV says it's outputting 12-bit 422 DV, it's LLDV, it's just the TV doesn't tell you that.

Also, the C9 Dolby Block tells us that 12-bit 422 is not supported (for standard DV)

LG C9
EB:01:46: D0:00:2A:18:03:51:59:99:AA
DV Version: 1 [short 12-byte version]
DV DM Version: reserved
DV Interface: standard and low latency 422 12bit
2160p60: supported
YUV422 12bit: not supported
Global Dimming: not supported
Backlight Control: not supported
RED Primary: 0.707, 0.293
GREEN Primary: 0.172, 0.797
BLUE Primary: 0.133, 0.047
MAX/MIN Luminance: 700 / 0.000 nits

 

I figured that in auto it was outputting LLDV, how do I switch it to tunnelling, is the only way to choose VS10?

 

Yes, unless you get an HDFury device which will allow you to send a Standard DV only EDID.

Your best bet is to leave on Auto (assuming your TV syncs quickly enough) and let it play out in LLDV as there won't be any difference - best case scenario is HDR10 base layer with a Dolby RPU and both modes do that.

I think that since the Sony debacle that caused all this, Dolby are now moving more towards LLDV as a universal solution.

 

Mmm not sure about that Mark, on the Oppo I definitely prefer TV led processing to Player led processing (LLDV)

 

The Oppo is a completely different beast - in Player Led, it can decode both HEVC layers and process BL+EL+RPU - the Zidoo can't do that and obviously TV led is how it should be done - both video streams hit the TV and it does the full 12-bit Dolby magic!

 

The most interesting development at the moment is converting Profile 7 BL+EL+RPU to Profile 8 BL+RPU - not really sure how the enhanced layer gets incorporated in the Profile 8 base layer to maintain the integrity, but it's hellishly interesting!

 

Hi Mark, I have been creating these profile 8.1 files with Yusepes Gamma 004 tools they don’t trigger DV on the Z9X, on the shield with latest Plex they play fine (apart from the well documented colour space problems). If Zidoo could recognise the parched Data in these files we might be onto a winner.

 

Ok - that's odd. Must admit I haven't tried that yet but I've tried a couple of Dolby produced Profile 8 streams and they spit out in DV.

There are two flavours of Profile 8 (ignoring the various Levels), one with an SDR compatible Base Layer and one with an HDR10 compatible Base Layer - the streams I've tested have a Cross Compatibility ID of 1 which is HDR10 and of course since yours originate from Profile 7, they will be the same.

If you want to snip out a 2 minute sample using MKVToolnix and PM me I'd be interested to take a look..

 

Posting now, check PM in a bout 10 mins.

 

say, with the new firmware, would the dv for hdr be the preferred setting if the set supports dolby vision ??
is the results the same as lldv for hdr content ??
not sure if any other video setting changes from the latest firmware.

 

It's purely personal preference - if you have a DV display and want SDR passed through but HDR processed as DV, then yes, select VS10 for HDR, and VS10 will convert HDR to DV along with native DV (supported formats) passing through as DV.

 

Clarification question: I’ve SDR Plasma TV, so if i choose DV10 engine, everything will br processed by DV10 engine, remapped to SDR BT709, and it will spit out SDR BT709 to the TV. Is my understanding correct?

 

Yes, that's correct but unfortunately VS10 SDR currently has a very washed out look - although black and white clip are correct, the luminance of the whole image is raised so it looks lifeless.

You may be better off using "SDR.Rec.709 Limited" or even "Dolby Vision VS10 Engine for HDR".

 

i found if you check the mkv after gamma and it shows as mel 8.06 ,but Zidoos playing it in hdr...............run the mkv thru Makemkv.53 and itll start working showing dolby vision correctly.....thou with the normal stutter audio lags after 3-5 mins as we checked on justice league on the other thread
