    Thanks @Markswift2003 I'll have a delve once the new firmware has been released as am quite busy at the moment :)

    I must thank you again for your help, without which I might have returned the product.
    I had trusted the default settings, thinking that they were the optimal settings for a standard setting, which should work without having problems.
    I did not think that a more specific setting was needed to avoid the problem I had described, it would be desirable for Zidoo to default to the setting you recommended.
    I tried last night and this morning both HDR and Dolby Vision files, they go into play after about 4-5 seconds, counting after the player circle.

    I would like to take the opportunity to ask 3 questions if possible, apologizing for some inaccuracies.

    1- Maybe I am not familiar with the topic why set the HDMI interval to 16-235 instead of 0-255 because it is not allowed by the HDMI standard?

    2- Is it possible to expand the internal memory (16GB) via USB ?, this would be useful to me for increasing the size of the Kodi database (ZDMC).

    3- Some UHD movies have both HDR10 and Dolby Vision encoding, is it possible to set preference only for HDR 10 ?

    Thanks for the answers

    1 - Video is encoded at 16-235 (or 64-940 for 10-bit) so I think it's best to chose the value discretely rather than let Auto decide.

    2 - Simple answer. No.

    3 - If you have a Dolby Vision display, the Dolby Vision layer will always take precedence, but you can set the EDID for HDR10 only to stop this (#3 would do it, or you can send me your EDID and I can remove the Dolby Vision bit).

    I thank you, everything is explained now.
    I'm just recontracting a little problem, with ZDMC 19.4 I can't play any file it returns me the message "Unable to play video", yesterday it was working.
    I uninstalled and reinstalled the app I restarted the box , but I can't play any file, do I need to do any special setting?

    Thank you

    No idea - ZDMC was deprecated years ago when it was replaced by HT. It's sort of a pet project with the devs although not officially supported but it seems to have become more popular recently for some reason, but I don't even have it installed.

    I think there was some issue with it recently, don't know if that's related to your problem, but try the latest firmware.

    Also, there's a new one on the way soon... (firmware, not ZDMC!)

    Since the problem is with the firmware I have posted in the specific thread.
    I apologize for this issue which does not pertain to this section.

    Good morning.
    Maybe I have the wrong setting for my display (LG 65B6V).
    I left the selection "LLDV Priority (LED TV)" by default.
    and when I play a 4K Doby Vision file, I get 1080p resolution on the output.

    I had to set the compatible mode to "Priority Standard Mode (LED TV)" to get the correct resolution on the display.

    First thing to note there is that the Italian translation is incorrect - LLDV is Player Led, not TV Led - so that's a mistake by Zidoo.

    The next thing is that the LG B6 is TV Led only so the correct setting would be Standard DV (TV Led) not LLDV.

    (To be honest it shouldn't actually matter - if the TV is either TV Led or Player Led but not both, the priority setting should not make a difference so I'm not sure why it comes out as 1080p)

    In any case, as I say, the correct setting for your TV would be Standard DV (TV Led) so set it to that.

    Thanks for the confirmation, some default settings are misleading.

    Default settings aren't really misleading - for example they suit to majority of users who don't want to mess with settings.

    Most DV TVs these days are both TV Led & Player Led DV compatible so the default is usually ok.

    However I think there is a fault with that setting with a TV Led only TV because as I say, it shouldn't output 1080p like that, but at least there is an easy fix.

    Good evening.
    Today I played a Dolby Vision demo file, with the current settings, I get @1080P output and this time, unlike other case that happened to me, it does not depend on LLDV priority (LED TV).

    [​IMG]

    I was only able to get the @2160p output by turning off the auto frame rate.
    I cannot understand this behavior, maybe it depends on the particular file?
    Thanks for the advice

    It's because your TV does not support 4K50, 4K59 or 4K60 in Dolby Vision.

    This is a translation of the B6 Dolby Block:

    LG B6
    EE:01:46: D0:00:24:18:09:00:AD:52:44:A9:23:0C

    DV Version: 1, [long 15-byte version]
    DV DM Version: v3.x
    DV Interface: standard DV only

    2160p60: not supported
    YUV422 12bit: not supported
    Global Dimming: not supported
    Backlight Control: not supported
    RED Primary: 0.676, 0.320
    GREEN Primary: 0.266, 0.660
    BLUE Primary: 0.137, 0.047
    MAX/MIN Luminance: 700 / 0.001 nits

    That file is 4K59, so because it cannot play at 4K59 and 59.940Hz (the frame rate) is not an integer, it can only play at 2K59.

    You'll find that if you play a 4K60 file, because 60Hz is an integer, it will play at 4K30 instead of 4K60

    Thank you very much for the very comprehensive explanation, actually it is a 2016 display a bit outdated, maybe next year I will upgrade with the new series.

    You should try all those resolutions and refresh rates from Zidoo quick setup. You may find that some sets work just fine but are excluded in EDID .

    Do you mean to change the frequencies in the resolution section?
    I currently have the resolution locked (3840x2160P 60Hz)
    Thank you

    Yes, unlock it and change it right there. Choose different resolutions and refresh rates. Zidoo will change output of this Quick Settings screen on demand ignoring EDID. If the screen goes black, no go for this pair. Just use back button. If you disable option of "Switch resolution and refresh rate" it will maintain your selection into the movie let's say 4K at 59fps.

    Won't work - This isn't an issue with the EDID as such - the B6 EDID has an HDMI 2 block and allows the full 600MHz TMDS character rate. This is a restriction in the Dolby VSDB.

    So turning off Auto Framerate and Resolution will just result in the Dolby VSDB forcing the box to revert to 4K30 for 4K59 DV content, using the nearest, but logically incorrect, frame rate supported in order to maintain 4K resolution.

    This will of course also happen if you set "Ignore EDID" in Developer Settings and try to force 4K59. The Dolby VSDB overrides it.

    Leaving Auto Framerate and Resolution on allows the box to use the correct logic and select 2K59.

    Yes you are correct Mark. I just tested it on my LG OLED E6 very similar to LG B6 both from 2016. I have Gemini Man UHD DV @ 59.94 fps.
    Just like you said. All auto turns it into 1080 DV at 59.94 fps. Locking resolution to 4K and 60 fps runs the movie in 4K at 30fps.
    Movie looks good both ways but I'll go for 2K DV at 60 fps.
