EDID thread (RTD1619DR players)

My setup is topping out at 30fps for HDR/VS10. It will do 60fps for SDR including the main menus. Panasonic HZ1000 via NAD T758 AVR. Apple TV works HDR/DV @ 60fps through same path. Used same cables as ATV and same issue.
Do I need custom EDID?

 

Hey Mark, thanks again for taking the time to have a look at it. I've been trying the different EDID's you sent and uploaded recently. I think I've come to the conclusion that the LLDV is not the problem. Recently I've been trying the BT.2020 HDR10 edid, and to my eye has a fuller picture than the other options, although it's struggling with shadow detail and a bit crushing. I'm thinking that the VS10 is only processing the HDR10 profile embedded in the file. Is that correctly understood? Is there a way for the Zidoo to process the DV layer in the File and output it in, say, BT.2020 HDR 200nit? Without me having to manually select the HDR on the projector (cuz mine cannot)?

Would there be any benefits for me to purchase an HDFury product? I've heard a lot about these as a way to solve all these sorts of problems.

 

This mega link is dead for me fyi

 

All fixed - I'd moved some of the EDIDs around on Mega - just checked them all and all links are working now...

 

Hello,

Can someone get the following EDIDs?
- LLDV BT2020 200Nits and HDR10+ passthru
- LLDV BT2020 400Nits and HDR10+ passthru
- LLDV BT2020 600Nits and HDR10+ passthru
- LLDV BT2020 800Nits and HDR10+ passthru

Thanks for your help

 

What do you mean by "passthru"?

 

When a video file contains and HDR10+ layer able to let it go out from the Zidoo even if it also contains a DV layer.

 

I thought that's what you meant - unfortunately you can't do that with EDID, or at least you can't do that if the EDID supports DV and HDR10+.

All the EDID does is tell the source what is supported, it can't prioritise. The only way to do what you want through EDID is to use one that supports HDR10+ but not DV.

If you want to be able to play DV/HDR10 in DV and DV/HDR10+ in HDR10+ the only way to do it without fiddling with settings or EDID is to strip the DV layer from DV/HDR10+ content.

On the odd occasion I do this I use Quietvoid's DoviTool.

 

So I will test this one you have added in the first page:

By Request:
BT.2020 400nit LLDV HDR10+

Thanks

 

Can you explain what modification has you included in this EDID for T1?

 

I think I just reduced TMinPQ in the the Dolby Block from 0.057 to 0.001 nits

 

Funny thing, when I powered on my Z9x last night, VS10 was outputting everything in HDR again.. not sure why it switched... but, I was still using my old Denon non-HDR capable EDID. Now I loaded your new SDR Rec709 300Mhz EDID and will see if it holds.

 

Can you post that Denon EDID - there's just no way the Zidoo can output HDR if the EDID doesn't allow so I'm curious...

 

I think I had sent it to you via AVSForum private message a while back along with the EDID for directly to my Epson?... if you still have those messages... otherwise I can send it to you later today...

 

If you can send it later that'd be great - my inboxes get rather congested here and on AVS

 

This should be my original EDID going through my old Denon 5200 which was not HDR compatible, and this is actually preferred now as I only want to use VS10 for everything converted to SDR. But, twice now, Zidoo has started displaying VS10 in HDR mode.

 

So firstly, yeah, no way the Zidoo can push out HDR if it's actually using that EDID, so if it was pushing out HDR, it couldn't have been using that EDID at that point.

Let me get this right:

1. Your current setup is HDR compatible?

2. You have your Denon SDR EDID loaded in Custom EDID, selected, and Custom EDID is switched on?

3. You have HDR set to Dolby Vision VS10 Engine (for all content)?

4. Was this a cold restart (power off at back), warm restart (power off on remote) or standby restart (standby from remote)?

5. When it booted into HDR, it stayed in HDR?

6. When it booted into HDR were there HDR options in HDR settings (eg Mapping HDR10)?

6. What told you it was in HDR - the TV reported it, the Zidoo reported it, or both?

 

I had a similar problem last night. I have the custom Rec709 EDID as suggested by @Markswift , with VS10 set for all content. All good for a few weeks until I powered it on last night, everything, including menus looked washed out. I played a few videos, and they were being output as Rec 2020, with my PJ now defaulting to HDR mode. This I think explains why everything was washed out. I reset the PJ to standard Rec 709, went into the Zidoo settings and checked that the custom EDID for Rec 709 was selected, which it was. I turned off the custom EDID, waited for the resync, and then turned it back on again for the Rec 709 EDID. The image quality was restored, and everything was output as Rec 709. Watched a few videos, and the quality was excellent. BTW I Have Z9x - Yamaha 3070 receiver - JVC X5500

This has happened twice now in the past month or so, and it's obvious when it happens due to the washed-out images. It appears that the custom EDID is not always sticking but is pretty easy to fix.

Cheers

 

1. Yes.. I swapped out the 5200 Denon for a newer 6200 which is HDMI 2.0 HDR/Dolby Vision capable...

2. YES, loaded, selected and Custom EDID switched on.

3. Yes

4. Not a cold restart, I always use Warm restart... Power OFF option selected.. not Standby.

5. Yes

6a. When I checked the Zidoo Display menu settings, I believe the normal HDR options were all there.. but can't be quite certain.

6b. What first clued me in , was that my opening Zidoo Menu screen maybe looked just slightly different?... When I hit the INFO button on my Epson, it showed it was receiving a constant BT2020 signal (instead of the normal BT709, YUV 422 SDR signal) and thus it had switched into HDR mode. Pretty sure when I checked with INFO button of the Zidoo, it confirmed the HDR output as well.

Next time, I will definitely document with photos. This has happened a couple of times now using my Old Denon Custom EDID feature... i just figured that somehow the Zidoo was detecting that my system actually is HDR capable and confused it somehow.

 

I've tried everything to replicate this and just can't and it's not something you can debug because it happens on boot - the only way I can think to debug would be through UBoot and that's, er, problematic

But yes, if it happens again, some screenshots would be useful - really can't think what would cause this and I can't help thinking a factory reset would fix it. But think carefully what you need to backup and what settings need to be changed back if you do that...
