Recommended Settings and other useful stuff for RTD 1619DR Players (HT PDF Updated July 2026)

Hi,
thanks for your reply.
One thing bothers me, now that I've seen it. In "CONSTRUCT CUSTOM DOLBY VISION DATA BLOCK (for advanced users only):" there is a description saying: "Generates a 12-byte DV Version 2 Data Block. Select AUTOMIX with CUSTOM STRING -flag to activate." If I understand this correctly, if I set up Custom EDID (I loaded your provided file at slot 1), then it doesn't matter what I set on DV page. Right?
So I only have HDR/AVI page which might be relevant.
Here I do have to check "Use custom HDR for TX0 and TX1 when input is LLDV", otherwise I get no HDR output, if I remember correctly.
I asked about the settings in "HDR METADATA GENERATOR:" on Discord, they told me the same thing: written to memory and forgotten on browser refresh and/or reboot.

So in sum:
I set Custom EDID and load your file in first slot.
HDR/AVI as posted above.
DV might as well leave it be or ignore?
In Zidoo:
HDR -> Auto (or LLDV?)
Resolution -> 4k/23Hz
HDMI Range 16-235

On by beamer I will also set 16-235 fixed. Rest is auto and frame adapt HDR (dynamic tone mapping).

One thing I find is that a picture is pretty dark. As I said, never had much to do with HDR, so not sure if that's normal, but is that something Vrroom might be causing due to wrong settings on the HDR/AVI page?

 

Exactly - as long as you have "Custom" selected and not "Automix" on the EDID page.

Yes - the beamer doesn't know what LLDV is, but it's the same signal as HDR10 when you set the primaries to BT.2020 which is why we fool the beamer into going into its HDR mode.

If you set HDR to Auto, everything will be native, including Dolby Vision and the PJ will sort it out

If you set HDR to LLDV, the Zidoo converts SDR and HDR to LLDV as well as outputting Dolby Vision natively as above.

Again the beamer sorts LLDV out because the Vrroom tells it that it's an HDR signal coming in..

No, the image shouldn't be dark, it should be bright and vibrant. Can't see anything in the Vrroom setup that would do that - you're using 1000nit LLDV EDID and the HDR message is set to 1000nit so they match...

 

I can confirm that your speculation is correct from experience with my HDFury. For at least the HDR and DV settings they're write only. Their display resets to the default when your refresh the browser window. I never figured out why those are that way while most other settings are live values. Probably either lazy or an issue with reverse engineering the string that's being sent.

I would also use this EDID - it's more accurate and has HDR10+:

Hello Mark
is the one you put in the above link better or the same to the "BT2020NEW 1000nit LLDV" ?

Thank you

 

It's the same, with the addition of HDR10+.

 

In 'LLDV' the addition of HDR10+ is what ??

 

The EDID also supports HDR10+

 

Ok thank you, but then on the zidoo we adjust how:
-Auto
-everything VS10
-or lldv 12 bits ......?

 

Not sure what you mean.

 

So, with this Edid we adjust the zidoo?

 

Depends how you want to view SDR, HDR10, HDR10+ and Dolby Vision and what display you have.

This EDID just adds HDR10+ support so it's possibly useful for people who want to use the LLDV trick who have displays that support HDR10+ (and obviously not DV - eg. Samsung TVs and later JVC projectors).

It will have no effect on displays that don't support HDR10+.

 

Ok I understood so for me I keep my usual LLDV with your New Edid!
Have a good day

 

Hi Mark,
Some help needed.

My setup: Z1000Pro/Chromecast w GoogleTV -> DenonX3500 -> SamsungQN90B

I used your HDR10+ only (no LLDV) EDID and im getting HDR, HDR10+ and VS10 DV logos displayed from Zidoo based on my source. But my TV still shows only HDR (notHDR10+). This is because of my receiver not supporting HDR10+ right?

Another issue is with this EDID on Zidoo (HDMI1), now my Chromecast streamer (HDMI2) does not send HDR signal to the TV when I play Nflx 4K HDR content. Any way to fix the chromecast no HDR signal issue?

Thx in advance for your inputs.

 

Yes, exactly - The 3500 doesn't support HDR10+. I have an X7200 connected to a Samsung display and have the same problem.

The EDID in the Zidoo can only affect the Zidoo - it can't affect sources connected to a different HDMI port on the Denon. The only way that could happen is if you have an HDFury device connected downstream of the Denon - ie on the Denon HDMI out.

 

Does anyone know what the High performance mode in developer settings actually does? Is it clocking higher or for longer, or just speeding up animation time?

 

Hi Mark, the Denon HDMI out is directly to the TV. Somehow the 4k60hz Chromecast color format was downgraded to 420:8 hence no HDR. Based on your inputs, i focused troubleshooting just on the Chromecast and found out that the Denon HDMI is set on 'standard' instead of 'enhanced'. Setting back to enhanced solves the issue! Thx for pointing out the EDID has no impact on other HDMI ports!
Also, I guess no HDR10+ until the next Denon upgrade haha. Thx again for your help!

 

Hi again, Mark, some new questions on HDR modes on the Zidoo. I watch most content on native SDR/HDR10 now.

As for my DV content, what is the difference between VS10 only and DV LLDV? Is LLDV for a SDR only TV? I want to make sure im using the optimal mode for DV on non-DV TV.
Im currently using VS10 (DV content only). Is VS10 for HDR10 better then native?

Thx!

 

Is it just me and my Z9X with FW v6.4.42, or are online TRAILERS in PosterWall (Home Theater 4) are also very low resolution for you as well?
When viewing in the small viewport in the movie info page, it is already quite pixelated, and has compression atrifacts, but when I'd try to watch fullscreen it looks awful...

Would it help, if I'd install a google-enabled "_G" FW and install Youtube app as well from Google Play (as far as I've understood the native YT app works up to 4K)?

 

If your TV support HDR10+ but your Denon does not support HDR10+, you still can get HDR10+ from Zidoo if you are using a HDMI splitter to split the display (via HDMI out 1 to TV) and sound (via HDMI out 2 to Denon).

 

Heya guys,

I need your help.Just got the Z10 Pro to replace the Nvidia Shield and Plex for local streaming of 4k MKV rips from NAS.

I have used the recommended settings from page 1 and can’t seem to be getting Dolby Vision on my Sony AG9.

Same MKV has no problem being displayed in Dolby Vision through the Nvidia Shield.

I am using the HDMI cable that came with the Z10.

Any help is greatly appreciated.

Thanks
