    I have an Epson 3800 4K projector that is NOT DV capable. If I want to view DV content so which Zidoo product should I buy or do I need to get an HD Fury?

    All current Zidoo models (RTD 1619) will allow you to view Dolby Vision on your projector. They all have exactly the same video performance.

    The easiest way is to allow the Zidoo to just convert DV content to HDR10 for native display on your projector.

    I'm not sure whether Epson projectors can be manually switched into their HDR mode (I suspect not) but if they can, you can use a custom EDID (included) to fool the Zidoo into producing BT.2020 LLDV and view that natively as Dolby Vision by manually setting the projector into HDR10 mode.

    If you can't do that, an HDFury device is necessary to send a spoof HDR SEI message to the projector alongside the LLDV signal from the Zidoo so that the projector thinks it's an HDR10 signal and switches into its HDR mode. In this case you can either used the built in Custom EDID function in the Zidoo or load one into the HDFury.

    I would recommend using an HDFury Vertex2 since that allows for sending the SEI message if and only if an LLDV signal is received at the input.

    If you use something like an Integral2 or a Vertex1 then this will work, but the SEI message has to be permanent and not dependent on the input type which is much less flexible and a serious issue if SDR content is used.

    Good news, here is my reply from Epson:
    Auto is recommended and Yes, you can set it manually.
    Best Regards,

    Cool - that's great - so you can set the custom EDID in the Zidoo to BT.2020 LLDV, get the Zidoo to output LLDV, set HDR manually in the projector and boom - Dolby Vision.

    Yes, here are the instructions from Epson support:

    See page 88 on the online users manual. It is under Signal Menu >Dynamic Range.

    From the manual:
    Dynamic Range Dynamic Range Signal Status HDR10 Setting HLG Setting Dynamic Range: sets the range of dark and bright areas in images; choose from Auto (recommended), SDR, HDR10, or HLG Signal Status: displays the image signal HDR10 Setting: adjusts the PQ curve from 1 to 16

    and edid info:

    Advanced Video Range EDID Image Processing Video Range: sets the video range to match the setting of the device connected to the HDMI input port EDID: sets the EDID settings; select Normal for 3840 × 2160 30Hz signals; select Expanded for 3840 × 2160 60Hz signals

    So I select Expanded for 3840 x 2160 60 Hz signals right?

    Awesome - just had a look - so yes, you set the Colour Space to BT.2020 and the Dynamic Range to HDR10

    The EDID setting won't matter because you'll be using a Custom EDID in the Zidoo, but yes, I'd set for Expanded for other sources - not that you'll need 3840x2160 60Hz very often!

    I've moved the thread to the 1619 forum - this info may be useful for other users.
