EDID thread (AML S928X players)

Ok - not see that - testing.

@rockmeloman , is that what you saw?

 

No, in my case it wasn't the poster in HT that was blinking, but the entire screen when switching between folders in the media center. I launch movies not in HT, but in the media center (file manager). This happened once and never happened again. I can't reproduce it. If it happens again, I'll record a video

 

Ok, I can replicate this, but it's not cut and dried.

I created a file called "Biography - Dalai Lama - The Soul of Tibet 480p XviD MP3 2.0.mkv" to replicate yours.

I scanned it in and it was identified incorrectly as a 2023 doco called "Biography" directed by Brighton Grace - so we have a director, and there's a photo associated with him also.

On my usual "posterwall" view, this did not flash, however on list and coverflow I got the flashing. So it only manifests on List and Coverflow views.

I then "rematched" in the UI and used the suggestion of "the soul of tibet" and the correct film was identified and I applied it.

So now I have the film shown as per your video file with the same coverart etc, except that now there is no flashing in any of the poster views...

I then added Big Buck Bunny, and this was identified first time and this one flashes on List and Coverflow too.

So I suspect that if The Soul of Tibet had been identified first time it too would have flashed. This is borne out by entering the web UI, selecting "Modify Data" for Big Buck Bunny but just hitting <save> without modifying anything - this stopped the flashing. So it seems if the data is resaved, the loop is broken.

Upshot is I don't know yet what causes this, but I can send a file to the devs to replicate.

Workaround in the meantime is to select the file in the Poster view of the web UI, select Modify Data and just hit Save.

Rematching to the same film in the HT UI may also do the same, but I didn't test that.

If you have any more thoughts, they'd be extremely welcome before I approach the devs about it.

 

Thanks for the workarounds. I'll try them tonight or tomorrow night after work.

I don't have much more to add, except that at one stage there seemed to be a short TMDB outage and I ended up in a situation where I had titles with all directors/cast only having placeholder icons. That caused a similar problem. I don't have a convenient way to reproduce that scenario.

 

Cool! I think that's important - that makes more sense - placeholders, or more correctly lack of online image, triggering a fetch loop. Almost explains why it happens with no cast or crew too.

 

I tried that with 1 Giant Leap: What About Me? A manual rematch from the HT UI did not stop the flashing. Neither did a rematch from the web UI.

Same result with Big Buck Bunny.

I tried that with 1 Giant Leap: What About Me? This failed with "Operation Fail" message. Maybe the web UI does not like the question mark. (Perhaps it needs escaping?)

With Big Buck Bunny, the save from web UI worked and once I did that, the flashing stopped.
For The Dalai Lama movie, save without changes from the web UI also worked and stopped the flashing.

All of these files were listed under Movies.

I have found two TV shows named Cultureshock and Stephen Hawking and the Theory of Everything Season 1 that have no cast and no director. Neither of them flash. I suppose there are some differences between the code that displays movies vs TV shows.

 

Funky!!

I'll be sending files and description to the devs - at least this is easy to replicate

 

Hi,Mark. I am setting up my new home theatre with zidoo 8K connected to an onkyo avr and a jvc projector. Could you please help check my edid and add a dv block to it with max nits of 1000nits and 4000nits. Thank you.

 

Remind me next week when I’m back from holiday.

 

Hi, new member from Curaçao. First off all, it’s refreshing to see such a helpful community, especially considering how complicated these setups can get.

I’m new to setting up a home theater, especially in trying to optimize the video/audio performance of the equipment. I have all my media on a Synology NAS (MKV rips of blurays and tv shows). The content I have is SDR, HDR10, HDR10+ and Dolby Vision.

I have recently purchased an Epson QB1000 projector (supports HDR10, HDR10+, HLG), but I’m still using my Sonos system for sound (not ready to choose AVR/speakers yet). As a result i also bought the Ezcoo switch/audio extractor to have video go to the Epson and Audio into the Arc soundbar. Considering the apple tv4k does not pass through lossless Atmos (I was using Infuse) i have purchased the Z9X 8K to handle all playback. The Zidoo is on the way and I’m looking into setup options.

As should be expected I have gone down the optimization rabbit hole as soon as i started visiting the forum when looking for settings etc. There are so many options, but LLDV peaked my interest when looking into the EDID topic. So now I have some questions I’m unsure of.

1. As the projector supports SDR, HDR, HDR10+ but no DV and has DTM (not as good as the JVC but functional), should I aim to send all video as LLDV or keep all as they are and only convert DV to LLDV? Is there any benefit to send all as LLDV (picture quality, shadow detail, handshake issues etc)?

2. I’m assuming an HDFury is not necessary as the projector HDR setting can be set manually; however, if i set this to HDR instead of Auto, will this cause any issues for other devices like game consoles or when playing SDR content (if not changing to LLDV, i don’t know what the advise is based on point 1)

I hope you can help me better understand what the optimal approach would be for setting up this equipment or at least lead me in the right direction.

Thank you for any help!

 

1. You'll have to decide for yourself whether you prefer to use LLDV and if so, whether to use it full time or not - depends how the projector handles it. Personally, on my PJ, I use LLDV for all content. There is a benefit of reducing resyncs because the HDR mode doesn't change which can be further capitalised upon by setting "Auto Frame Rate" to "Match Frame Rate Only" so resolution stays at 4K.

2. As long as you can set the PJ manually to its HDR mode, then no, an HDFury device is not needed but of course this will cause issue for devices sending an SDR signal - you'll have to switch mode back to SDR or Auto on the PJ otherwise SDR will be treated as HDR (not pleasant!). An HDFury can automate this by sending a dummy HDR message allowing you to use Auto in the PJ and this is also advantageous because the HDR message can match values in the Dolby Block.

 

Noted, thank you for the detailed explanation. Some great benefits that are worth exploring for sure. I’d mostly be using Ps5x XBSX, NS2 and appleTv. I believe those can be set to output HDR as well or have you experienced varying outputs from those devices that could cause an issue if the PJ is set to HDR?

I will start out with the recommended settings you shared in another thread and play around with it. I hope you can help clarify some uncertainties in that case.

1. I’d like to start off by sending all signals as they are, and only convert DV content as the PJ does not support that. If using the recommended settings, will that be the case on the Zidoo, or will I have to add anything to handle DV content?

2. Are there any instructions available on how to setup LLDV for each HDR type on a case by case basis to compare how the PJ handles the material?

3. I also read about customizing EDID for specific cases to match nit output? Is that something that might apply in this case or would the existing EDID presets work ok?

thanks again @Markswift2003

 

1. That's the right way to approach it - just set HDR to Auto to begin with then everything is output natively with the exception of DV where for Profile 7 the HDR10(+) base layer will be output natively and for Profile 5 it will be converted to HDR10 using VS10.

2. It'll become apparent when you start to play with Advanced HDR settings and have an LLDV EDID loaded - you can choose to output each format and either SDR, HDR or DV and choose whether VS10 is used or not. But bear in mind that for DV processing, VS10 has to be used as it's the DV handler so in some cases the VS10 setting doesn't matter. Again, it'll make sense when you delve in there.

3. That's only really applicable if using an HDFury because in that case, for example, you can specify 400nits in the Dolby Block and match with 400nits in the HDR message from the HDFury. Theory is that VS10 will tone map after 400nits and the PJ up to 400, although real life isn't that cut and dried. But with DTM that becomes less important because the DTM determines what needs to be done after VS10 has messed with it.

My recommendation is to start with a 1000nit Dolby Block, get a base line and then experiment if you feel the need. The built in 1000nit EDID will suffice perfectly for that.

Eventually when you're happy with the picture and settled on an EDID it's a good idea to customise you own EDID with a Dolby Block because, particularly with projectors, there can be a latency value incorporated in your own EDID that won't be in others that can lead to lipsync error if you don't use your EDID - but I can do that when the time comes if needs be.

 

Thank you! Will start out as suggested. So just following the recommended settings with HDR set to auto will automatically output DV as HDR10 without any additional settings changes if I understand correctly?

looking forward to trying out LLDV, just reading about it is kind of confusing though, like you said it’ll likely make more sense with the device in hand.

Thanks again.

 

Yes, exactly right.

 

Hi Mark, I'm new to Zidoo, but I own a Dune that's a few years old.
I'd appreciate your help or clarification on a custom EDID setting.
My equipment setup:
Panasonic TX 55LZ1000E TV, compatible with Dolby Vision and HDR10+
Pioneer LX901 AVR (2017 model), compatible only with Dolby Vision and HDR10 (not HDR10+).
I'll be receiving a Zidoo Z30 Pro soon, and my plan is to use HDMI from the Zidoo to the AVR and then from the AVR to the TV, so I can keep all the HD audio.
The problem is that I'll lose HDR10+. My question is, can I use custom EDID to trick the AVR into displaying HDR10+ on the TV?
Thanks in advance for everything.

 

Unfortunately, while it's easy to fool the Zidoo into spitting out HDR10+ with a custom EDID, because the AVR doesn't support it, it will not pass the HDR10+ metadata so you still end up with HDR10 on the output of the AVR.

 

Thanks Mark, I was expecting that. I Will watch my movies with standard HDR or DV
Thanks again

 

Hi @Markswift2003 ! Finally went down the EDID rabbit hole and DV in my QB1000 never looked so good! I found that the sweet spot lies between 3000/4000nits as well.

The only thing I’m missing on the EDIDs I found you posted, is an EDID 4000nit LLDV which also allows HDR10+ that my projector is capable and whenever I turn on the EDID it just sends as HDR.

Would you have an EDID like that?

Thank you!

 

No problem - file attached.
