HDfury Vertex2 - Dynamic DV content from LLDV source on any HDR10 display

The whole point of this hack is to output all content using the VS10 engine in LLDV.

If you don't want to do that, just leave the Zidoo HDR mode in Auto full time and it will output all natively. Either way there's no reason to change the Vertex settings from EDID 10. If you leave the Zidoo in Auto all the Vertex is doing is allowing LLDV content to be output in LLDV on a non LLDV TV rather than converting all content to LLDV which is kind of the point!

 

That EDID is specific to that particular LLDV enabled TV, if you use it with any non-LLDV TV (Panasonic or otherwise) the primaries will be wrong.

The reason this hack works is that that custom EDID used has BT.2020 primaries specified in the Dolby Block and not the original IPT primaries so a non LLDV TV can use its standard HDR setting.

 

Yes, but the HZ1500 is a DV TV anyway - this thread is about enabling DV on an HDR10 TV.

That aside, does it work?

You'll have to be careful where you put the HDFury device in the chain because that EDID is LLDV only whereas your TV is Standard DV + LLDV - so you will lose Standard DV support for any devices in front of the HDFury.

Also, your TV has a max nits of 775 and the Pana 55 only has a max of 431 specified in the Dolby Block (that might not make a huge difference though)

 

Sorry - I said the nits might not make a huge difference - it is worth a try.

 

Appologies for resurrecting this old thread, but I don't want to pollute the forum.

I'm trying to connect the dots with my setup to get the "DV experience" with my setup, which looks as follows:

Zidoo Z9X -> Vertex4K60 -> Denon X4500H -> Epson TW9400 (UB6500)

Vertex is in the newest firmware version so is Zidoo player and the rest of the components.

I got the DV signal to the projector by using Profile 5 in the custom EDID field, but it was red tinted to a point where it was distracting. The picture overall popped and if not for the reddish tint it looked quite pleasing. I found Mark's EDID for the BT-2020 profile on hdfury's site that fixes the tint issue (thanks Mark for doing this fantastic work!) but after loading it the picture "returned" to what it looks like in HDR10 mode. I tested with a bunch of movies, dark scenes, bright scenes, scenes with high dynamic content, but other than LLDV image being a bit dimmer (maybe due to the 1000nit cap?) everything else looks the same.

Any ideas what I am doing wrong? I bought Zidoo specifically for this purpose

I'll post photos from my vertex config and the screen OSD info later today.

 

Is this a Vertex 1 or 2?

 

Can you post your Vertex config file?

 

It's Vertex 1 I believe. This one https://hdfury.com/product/vertex-4k60-444-600mhz/ specifically.

I does not have web if so I cannot login to it from where I sit. I'll capture GUI screenshots. Give me an hour or two ...

 

Ok - that's a Vertex 1 - easiest is to download the config text file and post here:

 

Here are the relevant SS. Ignore the source info on the top. This is my PC connected through vertex to the receiver. I have Zidoo on the top port

 

and here's the config ...

 

Ok - I think you've got your custom slots a bit mixed up.

The EDID you have loaded into EDID 10 is the Sony A1 EDID from EDID 5

EDID 8 seems to have one of my BT.2020 LLDV EDIDs loaded, but it's a 10/12-bit 444/422 EDID which you don't really need.

Try this one - load it into EDID 10 so it's easy to remember where it is! This is one of the big problems with the Vertex - the custom slots can't be renamed.

This is the same one I supplied to HDFury for the Vertex 2 and the one in the Zidoo.

Other than that, your settings look correct.

 

One thing you shouldn't forget is that when DV is displayed correctly it should look pretty much like HDR10 - Dolby Vision is based on PQ gamma (Perceptual Quantiser) the same as HDR10 and both use a wide colour gamut.

The difference with DV is that it uses dynamic tone mapping and is native 12-bits and even there the water is muddy as hell what with Minimal Enhancement Layers becoming more prevalent (so the DV signal is really 10-bit even though it spits out in 12-bit).

What converting to LLDV does do is to level the ground a bit - so all content is tone mapped to 1000nits* by VS10 and so it's easy for your projector to handle (even though in reality it will struggle to get to 100nits).

I'm not sure what it does qualitatively but there is a setting on the Epsons in the Dynamic Range menu to adjust how the PQ gamma curve is handled - maybe mess with that? (Page 75 of the manual).

* True DV content is dynamically mapped to a static 1000nit PQ curve by VS10

 

Your are the man! That was exactly it.

I tested a few movies last night and although in some of them, as you noted, the difference in IQ will be negligible - most had visible differences. The way I would describe them is like taking a picture, which looks good on its own and then running on them auto-tone and auto-contrast functions in photoshop. After you see the result you can't go back to the original picture

 

For projector owners I think it does more for SDR pictures than HDR, and obviously it allows us to view native Dolby Vision content with dynamic tone mapping. As you say, overall, a more pleasing picture.

 

Dear @Markswift2003

I'm hoping to get your input on my following issue with the current setup.

Zidoo NEO S -> Anthem AVM70 -> HDFury Vertex2 -> Sony XW7000

I'm using your custom BT2020NEW 1000nit LLDV EDID, uploaded into "10 - Custom #10". See screenshots below.

When i change the HDR/AVI settings of Primaries and Max Luminance [nits] to ITU-R BT 2020-2 and 1000 nits, and click Create IF and Send HDR - nothing happens. When i refresh the page the values reverts to DCI-P3 and 4000 nits.

My picture looks like it has too much contrast and the black are overly crushed.

What am i doing wrong?

Thank you in advance!

 

Hi! I've just receive today a HDFury Vertex 2. I've read some information, but I have no image in my JVC projector. Until now the Zidoo Z10 Pro has been connected to a Denon 6700, which is connected to a JVC N7.
Now the Zidoo is connected in HDMI0, the Denon in the HDMI TX0 (ARC/CEC/UP) and the JVC N/ stayed connected to the Receiver's HDMI out.
No image so far
I'm sure that I'm doing something wrong as it is the first time that I'm dealing with the HDFury. Eventually someone could help me in a step by step basis until I get there

 

I am currently using z2000 pro directly connected to sony xw7000, with a brightness of 3200 lumens. Is there a suitable EDID? Should I use LLDV or HDR10? Is it necessary to add HDfury? Thank you so much!

 

@Markswift2003 .. I have a similar question. I read a post in another thread where I believe you stated that LLDV output to your projector with custom gamma curve is the best it's ever looked. I'm a bit confused. I have an HDFury arcana and the various settings are throwing me off so far. My Epson 5050ub is able to change color space manually to bt2020. How do you have your LLDV setup? Do I require the HDFury device in the chain or can I simply select the LLDV EDID, LLDV for HDR settings and let the projector do it's thing without inclusion of the arcana. Last, every time I switch to LLDV setting on z9x. The menu and home theater are washed out. What am I not doing correctly? A bit perplexed by how to dial all this in so the menus, SDR and HDR all play with correct color. Thank you in advance as always for your help!

 

I also have Epson TW9400 Zidoo Z30Pro and I wanted to buy Vertex1 for Dolby Vision but I was advised against it because:

"The reason the Vertex is not suitable is that you must Enable the Use Custom HDR option when LLDV is sent from the player, and then must disable the option when SDR is sent from the player.
Other HDfury devices; Vertex2, Diva, Arcana, Arcana 2, and VRROOM. Those that do use the Vertex for Dolby Vision manually switch their projector into HDR picture mode, instead of manually enabling Custom HDR in the Vertex. But this requires that the projector has an option to allow forcing HDR picture mode."

Is this true? How do you deal with it?
Is there a lot of adjustment in Vertex to get DV?
