EDID thread (RTD1619DR players)

Short answer, no you don't.

Custom EDIDs are used to enable features that your HDMI chain doesn't support or disable features that it does support.

For example, enabling Dolby Vision on non Dolby Vision displays, or restricting bandwidth if the physical HDMI chain doesn't match the capabilities of the display's EDID.

 

Damn, that was an fast answer.
Guess I wont be bothered then. Might upgrade to an Z9X 8K soon though, because im happy with stuff and it is a bit quicker.

Thank you for the quick answer,
have a great day

 

Just happened to open the site when your message rocked up

You too!

 

There seems to be this constant misconception that HDR and Dolby Vision are supposed to always look super bright and vibrant.. that is not always the case.. the dynamic range of black to white (as well as the colors) is expanded and as such, some titles may appear to be darker than what you are used to.. depending on how it was mastered. Plain and simple, if the darkness bothers you, then adjust your display to compensate.. many TVs have a special Dolby Vision/HDR Bright setting you can use as well.. If everything is working otherwise, you do not want to mess with custom EDIDs unless you have a very specific output/ or function you want to restrict or change and know exactly what you are doing.

 

hi all, i hope this is the appropriate spot for this question. does anybody know if the z9x can push out a 1080p / 29.97hz signal to an LG G3? i could swear i used to be able to watch things in the correct resolution and framerate without having to upscale to 2160p / 29.97hz? am i having a memory wobble or is my box / tv bugging out?

i've had a fiddle with a custom edid in the past due to a soundbar passthru issue (since resolved), so tried to see if i could have another fiddle around in that section to get both devices to handshake again and see if the option would appear, but i can't seem to get that to work. any ideas?

thank you in advance for any help with this

 

i'm wondering if it's something in one of the recent firmware/home theatre updates? i could swear 1080/29 played correctly and didn't used to force thru 1080/30 instead? is this something you may be able to understand @Markswift2003 ?

 

I don't think I have any 1080/29 content to try - it's an odd combination, mostly only applicable to US broadcast content.

I would expect that as long as the EDID supports the relevant VICs it should work. Bear in mind that if the content is interlaced, HDMI only supports 50Hz and above at 1920x1080 which would then (probably!) result in the next highest resolution to match the frame rate which is 3840x2160.

To be fair, something has to upscale so it might as well be the box as it's very good at it!

 

cheers for getting back – i've been letting the box upscale as a temp. stopgap. it's for broadcast content, as you mention, which is bizarrely still using 29.97? i'm not the most knowledgeable, but i'm surprised it would be remotely necessary anymore! it's understandable why the z9x might have some hiccups.

i spotted an earlier post from last year of somebody having a similar issue, so it looks like it may not have been fixed, missed or is simply not fixable? is there anything i could alter in the edid for the time being to get it it back to playing the accurate framerate?

thanks again for your help

Yes, it's a complete mystery to me too why we still use 23.97, 29.97 and 59.94 when the reasons we needed them have completely disappeared!

Can you confirm what the content is - 1080i29 or 1080p29 and what it outputs if you have Settings/Playback/Frame Rate Mode set to Match Frame Rate and Resolution.

 

Does anyone have an edit for a Sony XW5000ES

 

Do you have a Sony XW5000ES?

 

Yes i have now a Sony XW5000ES

 

In that case you already have an EDID for a Sony XW5000ES.

 

Is there EDID for JVC DLA-NX7 projector?
I have zidoo uhd5000

 

Same question as above - do you have a JVC DLA-NX7?

If so then you already have an EDID for one.

If not, why do you want one?

 

Hey Mark, I'm posting in this thread because my question is specific to custom EDIDs.

You've been so helpful in the past sharing your own personal experience with the interplay between the ZIDOO boxes and JVC projectors and wringing the most out of them.

I know that you employ a 1000 nit EDID for full LLDV output of all input types. Per your instructions, I've been trying out and testing multiple permutations and can see that there are tradeoffs.. I've settled on the 10000 nit as the best for me as one of my priorities is full and absolute fade to black and this seems to be the only way to achieve this...
If I'm understanding things correctly, with this EDID, I'm bypassing the ZIDOO tone mapping completely in favour of the JVC's excellent frame by frame solution... which begs the question am I better off forgoing DV altogether and simply playing the HDR10 layer of each title... I'm trying to let my eyes decide but it gets complicated with all of the changes that need to be made between A/B ing a certain scene not to mention the reality that each disc will have it's own idiosyncrasies between its HDR10 and DOLBY layers..
I guess what I'm asking is for a simplified explanation of what is going on with with a 10000 nit LLDV with DV titles versus HDR10 with the generic EDID..

 

Not sure why a 10,000nit EDID would behave differently with full fade to black compared to others, but I'll definitely test that later! I get FFTB with a 1000nit EDID but of course it depends on the content.

So yeah, a 10,000nit EDID is an interesting proposition and you're right, on first thought you might expect that to act pretty much the same in DV and HDR10 - However, although you're essentially telling the source that no tone mapping is required (which is the same as HDR10 with DTM engaged), trims are still active - so there is a benefit to Dolby Vision depending on creative decisions made during mastering.

Rather than trying to see A-B comparisons, it might be useful to have a period of full LLDV so you get used to the image and then switch over to HDR10 and see if you see any subjective difference.

 

In the last year, I've made a number of significant changes to my setup. Prior to that, I had been using LLDV exclusively for everything with your custom gamma on a JVC x570r and loving it. As much as I have usually shut off all "proceesing" modes on my displays, I fell in love with the "mode 3" dynamic control (laser dimming) when I upgraded to the NZ7. My HT is a completely blacked out cave - walls and ceiling painted black, all lights in my equipment stack are either shut off in the setup or taped over where necessary. When a movie fade to black, you cannot see ANYTHING, not even your hand directly in front of your face.. no matter how long you sit there and allow your eyes to adjust..pure ocular sensory deprivation. In my experience, this effect worked better with HDR10 than LLDV and I have been suing that exclusively for some time and been happy.

When I recently upgraded from the Denon 6700 to the A1H in order to gain WIDE channels, I continued this practice... Until recently, when I was routing around the settings of the receiver and discovered the "8K ENHANCED" HDMI setting. I don't know if my 6700 had this or just the STANDARD and ENHANCED settings that I assumed all receivers had (including my A1H)....anyways...I don't know all the ins and outs...but setting the A1H to 8K ENHANCED greatly improved my fade to black with LLDV and I do notice a more 3D punchier look to material I am familiar with....but it's still slightly "elevated" from what I'm used to regarding black level...that is until I tried the 10,000 nit EDID....The black level thing is easy to see.. The opening voice over in the new movie WEAPONS, the "fade IN from black" at the opening of THE REVNANT and the whole opening scene of THE INVISIBLE MAN are completely different experiences...what I will be testing as I get the chance will be whether or not keeping LLDV on all the time with a 10,000 nit EDID is worth it over just going back to simply using the AUTO function in the ZIDOO's HDR settings. That is the harder thing to assess as I'm not well versed on what exactly is happening when the player is simply playing the HDR10 layer of a DV encoded file, or what benefit it is actually deriving from processing the DV layer in the ZIDOO when I'm employing an EDID that I think is essentially "throwing out"(?) that info...

This, I think, is the hardest thing to assess because I believe if I'm incorrect on that last point, then I am left to the creative decisions and perhaps mistakes being made in the mastering of various discs and I will have no choice then but to descend into madness...LOL..

 

Yes, the 6700 has the same "8K enhanced" setting - all this does is allow 4K 100/120Hz and 8K signals up to 60Hz through - basically allowing HDMI 2.1 signalling. In order for this to have any effect on content, you also need to set the enhanced output on the Zidoo (settings/Display/Color Settings/HDMI Signal Format > Enhanced Format).

Similarly, "Standard" restricts to a kind of hybrid HDMI 1.4 and "Enhanced" allows HDMI 2.0b signalling

So if the signal is, for example, 4K23~30 12-bit 4:2:2 LLDV, this can be passed using Standard mode as it's essentially an HDMI 1.4 level signal and it makes no difference to the signal whether "Standard", "Enhanced" or "8K Enhanced" is used.

4K50~60 12-bit 4:2:2 LLDV would need at least "Enhanced" because this needs HDMI 2.0.

But again, I can't see how that affects black level because, assuming the setting is such that it passes, the signal is the same in all cases.

I've just programmed some selection buttons onto my Crestron app to allow me to switch EDID on the fly from 100 up to 10,000nits - so I'm going to test that out to see how 10,000nits behaved. As I say, it shouldn't - but I know from experience that "shouldn't" and "doesn't" can be two entirely different things in this game with all the plates that are spinning!

I remember years ago, Dave Harper, who's as mad as a box of frogs, but a great guy, and the guy who first ame up with the LLDV hack all those years ago, extolling the virtues of using a 10,000nit EDID. But this was before DTM was as ubiquitous as it is now and we all thought he was nuts - but maybe he was onto something

 

Yeah..I'd like to consider myself as a man of science (even when I don't always understand the science- as is the case here). I kind of cringe when I hear HT enthusiasts say things like " I trust my eyes"...I generally believe in calibration and graphs LOL...

I can't explain what is going on as I don't fully understand what dark arts are behind the interplay of the competing HDR formats and the the tone mapping schemes of ZIDOO and JVC.

Whether or not I can trust them, I like what my eyes see with a FULL fade to black and I feel like colours are deeper(?) with LLDV. The FULL fade to black is achieved when I use LLDV with a 10,000 nit EDID and when I use no custom EDID and the ZIDOO set to AUTO. The FTB is at it's worst with LLDV and a 1000 nit EDID although it is (seemingly inexpicably)noticeably improved between my amp's ENHANCED and 8K ENHANCED settings for HDMI. I pretty much keep everything locked at 4K 23Hz...

To be clear, when I say FULL FADE TO BLACK, I mean so black that even after a few seconds of your eyes adjusting, you cannot see even the softest glow from your display. The best judge of this is the opening monologue of WEAPONS...Getting this right has major implication for this movie in and around the 26th minute and 36 minute mark....lengthy scenes that take place in near darkness but are essential to the plot that one knows what's going on.
