    Although this is essentially a copy of the first post in the EDID thread in the 1619DR forum, there are some fundamental ways in which the use of EDIDs can vary in the 1619BPD players, so I thought it was a good idea to start an EDID thread here too.

    RTD1619 Zidoo players allow EDIDs to be uploaded to override the EDID presented by the display, amp or soundbar.

    Amongst other things this allows the Zidoos to present an LLDV output with colour primaries that a non-LLDV display will understand.

    Effectively this allows true Player Led Dolby Vision to be viewed on a non Dolby Vision display since Player Led processing allows the dynamic tone mapping to happen in the player and the display receives a static gamma according to the St.2084 standard - essentially an HDR10 signal that has had dynamic tone mapping pre-applied to the video signal.

    You can even tailor this tone mapping to the display brightness by adjusting the max nits level in the Dolby block in the EDID.

    In order to use the LLDV hack you must be able to manually select HDR in the display (this is quite common for projectors but not with TVs) or use an HDFury device to spoof the HDR message.

    Here are a few EDIDs for the experimentalists!

    BT.2020 400nit LLDV


    BT.2020 1,000nit LLDV and HDR10+


    HDR10+ (no LLDV)


    BT.2020 4,000nit LLDV


    BT.2020 10,000nit LLDV


    BT.2020 400nit LLDV (10-bit 444/RGB, 12-bit 444/RGB, 12-bit 422) and HDR10+


    BT.2020 1,000nit LLDV (10-bit 444/RGB, 12-bit 444/RGB, 12-bit 422) and HDR10+


    BT.2020 HDR10


    Useful if you have a DV display but want to restrict the Zidoo to HDR10.

    BT.2020 HDR10+


    (this is really just for curiosity - however it's useful if you have a DV file with HDR10+ base layer and want to watch in HDR10+ rather than DV)

    400MHz BT.2020 HDR10


    (this one is useful if you have a long cable that won't support a full 600MHz/18GBps signal)

    400MHz BT.2020 HDR10+


    400MHz BT.2020 1000nit LLDV


    SDR Rec.709


    300MHz SDR Rec.709 (HDMI 1.4)


    BT.2020 400nit LLDV HDR10+


    And a slightly tweaked version of the one included in the Zidoo. This has the colour primaries slightly tweaked nearer BT.2020 (because of the byte allocation in the Dolby Block this can never be 100% accurate nor does it need to be):

    BT2020NEW 1000nit LLDV


    BT.2020 LLDV 100nit - 10,000nit EDID Collection

    Not sure to post in the good topic. If not let me know i will create a new one.
    My Setup: zidoo Z9Xpro connected to Marantz Cinema60 te marantz hdmi output is connected to a panasonic oled LZ15OO
    I have a question about dolby vision files:
    - i t seems the panasonic LZ1500 is limited to 10bits, but my marantz receiver accepts 12 bis signals...

    When I play a HDR10 or HDR10+ the signal transmited by he Zidoo is 10 bits and my TV shows a 10 bits signal input
    But when I play a dolby Vision file, the signal transmited by he Zidoo is 12 bit and my TV converts it to 8 Bits!

    I doesn't seem to affect the quality but it bothers me...

    I am a new user of Zidoo ( former HTPC user). If I understood everything I have read, it should be possible to make a custom EDID to limit the signal transmited by my Zidoo to 10 Bit.

    Am I right or should search another way to transmit dolby vision signals in 10 bits insead of 12?

    thank you fo your help

    What is your setting for Settings/Display/Dolby Vision Compatible Mode?

    Priority LLDV (Player Led), I tried both settings for the same result

    Ok, that's odd.

    TV Led is sent in an 8-bit RGB wrapper and unwrapped to 12-bits in the TV but Player Led is 12-bit throughout. I'm pretty sure the Panasonic supports Player Led and TV Led.

    When you say "my TV converts it to 8 Bits" what makes you think that? There is no such thing as 8-bit LLDV so the TV can't report that (at least not correctly!).

    Can you send me your EDID:

    To Download EDID

    Settings/Display/Custom EDID/Save EDID

    Save to a USB stick or network location.

    Change the file extension from .bin to .txt to upload to the forum

    (The forum won't accept .bin files)

    Yes that's odd, maybe it's just a bug from the panasonic that doesn't display the right informations...

    I performed a few more tests and here are the results:
    Zidoo=> Marantz Cinema 60 => Panasonic TV
    - Tv Led mode: signal info displayed from the Marantz : RGB /Bt2020 8bits |info diplayed from the Panasonic TV : YcbCr4:2:2 / 8bit / total
    - Player Led mode: signal info displayed from the Marantz : YCbCr 4:2:2 / Bt2020 12 bits | info diplayed from the Panasonic TV : YcbCr422 / 8bit / normal

    And las but not least, i tried:
    Zidoo => Panasonic TV

    -TV Led Mode : RGB/-/Total
    -Player Led Mode: YCbCr4:2:2 / - / Normal

    No info for Color depth are displayed o_O
    here are 2 backups of my EDID : the one when the zidoo is pluged to the marantz and one when directly pluged to the Panasonic TV

    Yes, I think you're absolutely right - I think the Panasonic is just reporting incorrectly.

    For TV Led, the signal is transported in 8-bit RGB but converted to 12-bit 4:2:2 at the display. There is no Dolby Vision mode at 8-bit 4:2:2 as reported by the Panasonic and indeed no HDMI mode either!

    Old displays used to have a problem deciding whether a signal was 8-bit 4:2:2 or 12-bit 4:2:2 because the bandwidth is exactly the same for both. What manufacturers didn't seem to understand is that 8-bit 4:2:2 does not exist in the HDMI spec, so if a signal is 4:2:2, it has to be 12-bit.

    So I think this a combination of the TV getting confused and the amp making it more complicated. Whatever they report, the signal will always end up as 12-bit 4:2:2 for Dolby Vision.

    I'll check the EDIDs later and let you know if there's anything odd, but I don't think so.

    Ok, thanks a lot for the explanations !
    I indeed found it weird to see this 8bit information so I wanted to understand what was wrong.
    Nothing wrong here, but my TV that tells me bullshit about what it is displaying :D

    I use a similar configuration (with a different receiver) and made a quick test with the blu-ray player with same result: RGB/8 bit/Full for a DV disk
    most of the TV settings are default and got the same on DV Dark and DV IQ

    Thanks for this, just beed some help.
    I have a BenQ HT4550i with a Z9x Pro connected via the Vertex 2 outputting to a Denon X4700H
    The PJ has HDR10+ capabilities but no option to force HDR and the vertex2 does its job and upon checking the DV status is says: Active

    I managed to play around with the Vertex2's default Custom EDID10 profiles to activate LLDV and so far it worked.

    Q: Do I need to download and load BT.2020 1,000nit LLDV and HDR10+ in the Vertex 2's UPLOAD EDID TABLES:
    upload it via Z9X Pro> Quick Settings/Display/Custom EDID/Upload EDID

    Personally I always load into the Vertex as a belt and braces approach to making sure the EDID is always present and it's also available to other devices if you want to use it that way (remember when you load a custom EDID into the Vertex, the name doesn't change from the default one so you have to remember where you load it).

    But it will work either way - if you load it into the Zidoo that will override any EDIDs you have set in the Vertex in the same way it would override your display's EDID if you didn't have the Vertex.

    I have same setup almost ie z9x Pro Pana LZ1500 with Denon 3800 in between

    I just did a quick check thru with my gear using a DV file

    Think the issue is in Display / HDR / whether you use Auto or (for me) VS10 DV all the time

    Im seeing with VS10 DV on i get same results in info for Player amp and tv ie 8 bit DV (TV-LED)

    If i change / HDR to Auto i get same 8 bit DV (TV-LED) in TV LED mode

    But in Player LED mode i see different info

    YUV422 12 bit BT2020 DV on Z9X Pro
    YCbCr422 12bit BT2020 DV on Denon 3800
    YCbCr422 8 bit normal BT 2020 DV on Pana l1500

    Me i prefer just leaving it on VS10 DV for all

    If you have to ask the question then no, probably not.

    I just started really digging into this custom EDID / LLDV stuff. I have a basic question. I run an Epson LS12000 projector and have been running Zidoo in vs10 (hdr output) mode.

    Does it matter then if I configure custom EDID to support the player doing LLDV, or is vs10 already kind of doing LLDV in software. I’m a bit confused on this point. Basically, what would I gain if anything using something like the BT.2020 LLDV custom EDID?

    That's a very good question - I don't think anyone's asked that before!

    The answer is yes, kind of, for both questions.

    If you use VS10 on a non-Dolby Vision display with Dolby Vision content, the Dolby RPU is used to tone map the output to whatever the display can handle, be it SDR or HDR10.

    So if the display is HDR10, the RPU is used to tone map to a static gamma.

    In the case of Profile 7 (& 8), the values for MaxCLL/FALL inherent in the HDR10 base layer are used - in other words it modulates the video output dependent on the RPU based on the HDR10 parameters of the base layer - and this is kind of what LLDV does.

    In the case of Profile 5 (and Profile 7 without these values in the base layer) MaxCLL/FALL are set to zero and the display will use its default gamma.

    But you also have to bear in mind that the way displays handle HDR10 are different - some correctly use MaxCLL/FALL and some don't. It's a bit of a mine field.

    What you can do with LLDV is to chose the point at which the tone mapping in the box (from the RPU) is handed off to the display by adjusting max nits in the Dolby Block and match that to the gamma curve in the display if you know what you're doing. It's kind of complicated and really needs an HDFury device to do properly.

    Bottom line is suck it and see - it will also depend on how your display handles HDR10 and you need the ability to switch the display either manually into its HDR10 mode or use an HDFury (Vertex2 or above recommended) to do it.
