EDID thread (RTD1619DR players)

Got it - makes complete sense. Thanks for clarifing....and yeah, gota love Dolby Vision

 

OK... I've setup and calibrated my new JVC NZ7.... I thought I downloaded the 1000 nit LLDV and set it as my custom EDID in the ZIDOO, but my son pointed out that there was an extra 0 in the filename while I was tooling around in settings.

So I'm using the ZIDOO as I always have with my previous JVC with a 10000 nit LLDV EDID and the projector permaset to HDR.

The results are JAWDROPPING no matter what I play - I've tried files listed as HDR, HDR10, HDR10+ and Dolby Vision...

@Mark, can you try one last time to explain to this simpleton what is happening in each instance re: tone mapping? I've got everything set to VS10 in the ZIDOO and HDR Dynamic Tone mapping FRAME BY FRAME on the JVC. I'm very happy with the results...I just want to know why...LOL

 

Me too on my NZ7 I am at 10,000 nits in manual mapping on HDR PQ with adjustments accordingly..............and the image is top notch!!!!!

 

I realized after the fact that I meant to make my last post in the settings thread where I was having a back and forth about this with Mark, who was patiently trying to help me understand this.

What I think I understand so far is that when you set an EDID with "x"NITS as a limit, LLDV passes the signal below "x" through to our projector unfettered and JVC's frame by frame dynamic tone mapping does it's thing. What I'm not understanding is what happens to the metadata encoded in HDR10+ and DV titles. As I understand it, this contains non static, frame by frame info of how each frame should look as decided upon by the person mastering the disc.

Our projector has an HDR10+ setting. I'm wondering what is happening when a ZIDOO with a 10,000nit EDID passes an HDR10+ video through to a JVC NZ7 that receives it in vanilla HDR mode. I'm assuming that, in this instance, the ZIDOO is throwing away the dynamic metadata (artists intent?) and the JVC is applying it's algorithm to interpret how each frame should look ( albeit with amazing results).

 

YES at 10,000 nits it's a bit the metadata of the file read by zidoo and mainly the DTM (auto or manual) of the JVC!
Personally I tested everything from 100 to 10,000 nits and it was 10,000 nits that I retained, because the JVC does an excellent job!!!
After all, all tastes are in nature.........

 

If that's the case, what's the difference between the 10,000 nits and Full custom edid's? @Markswift2003 - can you clarify Mark?

I assume one is mapped to 10,000 nits (so the display thinks the content is mastered at 10k nits), and the other is passthrough as is, but would be good to clarify.

 

Great news that you're pleased with the new PJ - DTM makes a massive difference to the old static gammas.

So yeah, I think you both figured out what's happening - with a 10,000nit LLDV EDID, the box assumes that the display is able to process the image without tone mapping, so the full ST.2084 curve is used without any compression (tone mapping) at the top.

Theoretically, for it to work properly you need to use an HDFury device to tell the PJ that the box is spitting out content with MaxCLL at 10,000 nits too so it has a baseline for tone mapping, but with DTM that actually shouldn't matter as each frame is analysed for content, including its luminance levels.

I believe the JVCs do prefer to know the MaxCLL/FALL/MDL values but I couldn't tell you exactly what they do with them - To be honest I don't think anyone can JVC tend to be very enigmatic when it comes to what goes on in their PJs' innards.

Ask them what the difference between Frame Adapt 1 and Frame Adapt 2 is for example and they'll probably say one has a 1 and the other has a 2. Even the venerable experts on AVS will try to blag it and fluff over the answers in a lot of cases.

Sorry - that's probably me being enigmatic - The "FULL" refers to the rest of the EDID - full audio and full 600MHz video - nothing to do with the Dolby Block or tone mapping.

 

Understood.

 

@Markswift2003 Hi Mark,

Might sound like an odd request, but if I say pretty please, any chance you could just add all sound formats known to man, without making any changes to the dolby block/any display info in the attached edid?

I tried this edid (the one captured with the zidoo connected directly to the display) and LLDV is brighter (lowlights and highlist are better) and much richer.

I can only think of two possibiities for the reason why: a) there is something odd in the onkyo block, or b) the sony engineers already factored in the display primaries when displaying a bt2020 signal in LLDV mode, or, mixture of both lol.

Hope the above makes sense.

 

Just to check before I do that - what EDID are you using at the moment because the Onkyo can't make any difference to the Dolby Block and the Dolby Block has to reflect the primaries that the display supports.

That Sony EDID has primaries very close to DCI-P3, not BT.2020.

 

Hi Mark,

I'm using the one I attached above, so direct from the Sony panel.

 

Sorry - I meant previously - you said this one improved colours in LLDV, so the one without improved colours - if possible, can you attach that too.

 

Understood - attached.

 

Ok - very odd - there's nothing in there that would affect picture, especially not to do with Dolby..

So I took the audio settings from the Onkyo EDID and put them in the Sony EDID (and changed nothing else) but I can't see how that would be any different to the Onkyo EDID...

 

When i uploaded the Onkyo edid, there was no info about the Sony display in that edid if you recall.

And thanks again Mark!

 

Yes, I think the original Onkyo EDID you posted removed the Dolby Block and restricted to HDMI 1.4 (or something like that) which is symptomatic off turning what manufacturers sometimes unhelpfully call an "enhanced" mode or similar.

But that Onkyo EDID you just posted didn't do that - it's HDMI 2 and has the Dolby Block - essentially it's the same EDID as the TV but with more audio modes added which is what should happen. So something changed in the setup between the original one and this one.

So both that EDID and the one I just posted should do exactly the same job.

 

Lol. I can see where the confusion is coming from - the 1st edid above today was from the Sony connected directly to the Zidoo, the 2nd edid I posted today was one where you merged all the info from the 1st edid into the Onkyo edid, and make a few tweaks to the colour primaries I seem to remember.

Anyways, all done now, and thanks again as always.

 

Ah ok - I assumed it was a grab from the box.

But no, the primaries of both of EDIDs you posted today are exactly the same - I wouldn't have changed the primaries because they're defined by the display, so if you change them then you do end up shifting colours...

 

Yeah, understood.

 

Thank god I found this thread hopefully it can fix my issue. I just purchased and installed my first JVC Projector, the NP5, I have been an Epson guy for the last 20-ish years spanning 7 projectors. Any who, I'm quite impressed with the JVC but ran into what I guess is an EDID issue with my Zidoo Z9X. Playing my 4k HDR 10 rips back on my Hisense 100" U88N and all is good as it detects the HDR and the Zidoo shows BT2020 but playing them on my JVC with the JVC set to auto it stays in SDR and hitting the select button to see the Zidoo info, it shows rec709 too. I have both the Hisense and the JVC connected to my Anthem AVM 70 8k with the TV out of output 1 and the projector out of output 2. I wonder if having both connected to the Anthem is causing the issue....and I haven't tried the projector by itself yet out of the Anthem. Would really like to experience my movies on the JVC in glorious HDR 10 but with the warnings about trying a custom edid and me not being experienced with edids I'm afraid to dive in by myself. So any thoughts on my issue, is there another Media player that just works or might this be an easy fix with a custom edid? Thanks
