Success! The DV v2 string used by the HD Fury devices is fully editable! Was able to confirm both maxPQ and color primaries can be changed. It’s probably easiest to just use automix and edit just the DV string, when editing the full EDID several blocks need to be correct for HDMI to sync successfully (mostly related to resolutions and timing). I’ll do a full write up tomorrow on how to calculate the values for the DV string. The only outstanding question in my mind is I f my formula for maxPQ is correct and if the player is actually using it.

I have attached the DV tab from a Vertex connected to my LG B7A. The B7A will accept LLDV output from my Oppo configured to output Player Led DV and it will report receiving Dolby Vision, but the Oppo will always default to TV led to my B7A.

The Vertex was configured to Automix mode.

Captured DV metadata block:
eb:01:46:d0:00:26:0a:09:75:80:5b:6c

Dolby Vision Version:1 DM Version:1
Capabilities: [2160p60]: YES
Capabilities: [YUV422 12bit]: NO
Capabilities: [Global Dimming]: NO
Target Max Luminance: 350 nits
Target Min Luminance: 0.063 nits

The NO to 422 12bit would seem to me to indicate that it does not report support for LLDV, even though will accept the LLDV 4K 4:2:2 12-bit signal and recognize it as DV.
Yeah, this is a DV v1 (really v1.5) string. It looks like LLDV bit is set, but yuv422 is not. It’s interesting that the TV is requesting 350nits, isn’t that a 500nit display?
Nalleh, vollans and ordivergens like this.

Thanks! That I think confirms the value and my calculation for max nits. That string would decode as 1000nits which makes sense for that display.

The v3 versions of Javs curves are quite good; both the jvc_gamma_1200nitv3 and jvc_gamma_4000nitv3 curves. They are definitely bright curves as I think he targeted 80 nits with them. Because we think the A1 LLDV tone mapping process is targeting 1000 nits, the 1200 v3 curve might be a good one to start with. Later on you can use the custom curve slot 3 to try one of Dominic's curves if you are not already using all three slots.

Also, in case you didn't notice, I updated my post to reflect that my LLDV custom user mode is just like my HDR10 user mode except that I replaced the BT2020 color profile with the LLDV_A1F profile from Dominic.
Ok Im up and running that was way easy i thought it was going to be like arves tools which was very nerve wrecking at first.. I do have one slot left for a curve but i don't know the process to upload it.. I'm also ready when you guys have time I want to have my rs640 switch modes when it detect's DV, Directv and 3D. Can someone post pics of their macro tabs always wanted to do this..

Thank you..

Do you have a DB9 RS232 cable and 3.5mm audio extension cable run from the HDfury device to the JVC RS-232 port? That is the first step.


DB9 serial to 3.5mm audio cable to connect to the JVC serial port:

https://www.amazon.com/SHARPALIN-Fem...1696766&sr=8-2


25 foot 3.5 mm Audio extension cable to connect from the above cable to the HDfury serial port:

https://www.amazon.com/KabelDirekt-3...1696885&sr=8-6

You can get a shorter one if 25 feet is not needed, or you can connect two extension cables together if the distance from your HDfury to the JVC is longer.


I have attached a screen shot of the Macros tab in my HDfury Diva.

SDR-BT709 (HDTV) for 60P
SDR-BT709 (Film) for 24P

- I have both of these set to DO NOTHING rather than have my JVC switch to my SDR-REC709 user mode. I do this so that the BT2020 filter does not click in and out each time playback of BT2020 material returns to an SDR menu. I watch so little SDR REC709 content that I manually select the user mode when I do.

SDR-BT2020 User 4

- User mode 4 is my SDR BT2020 picture mode. It is configured to use the BT2020 color filter and Gamma 2.4. Source is mainly MadVR playback of UHD discs.

3D
x.v.Color

- Both set to DO NOTHING as I don't watch 3D, and x.v.Color is for older JVC projectors.

HLG-BT709
HLG-BT2020

- Both are set to my User 6 custom user mode. I have a custom HLG curve loaded since my RS500 did not have HLG support like newer models do. I used to get HLG from Directv, but now limited to YouTube HLG videos.

HDR10 User 5

- If you have two custom curves, this is the user mode where you have your 4000 nit curve configured, otherwise set it to your single curve user mode.

HDR10-Opt User 2

- This is where you set the user mode where you have your 1000 nit or similar custom curve configured. Or to your user mode where you have your single custom curve loaded.

HDR10-Rec709 User 2

- This is where you would configure a user mode for HDR10 REC709. I have never seen such a signal and don't have a user mode configured for it. I just set it to the same user mode as for my 1000 nit custom curve. I could just as well set it to DO NOTHING.

LLDV User 3

- This is the new macro added to the latest generation of HDfury devices (Vertex2, Diva, and Maestro). This macro will send the RS-232 command to the JVC to switch to my custom user mode configured for LLDV.
- Note that if you have the original Vertex, it does not have this LLDV macro. When the Vertex sees LLDV it treats it as SDR BT2020 and will send the command to switch to your SDR BT 2020 configured user mode. If you don't have a SDR BT2020 user mode because you never have such content, you can enter your user mode for LLDV into the SDR BT2020 macro.

Each time the HDfury sees a content type change, it will execute the appropriate macro for the content type. The macro will send the proper RS-232 command to the JVC to select the configured custom user mode. If the macro is set to DO NOTHING, the macro will not send any command.

The CUSTOM HEX strings beside each macro allow the macros to control displays other than JVC. Leave them as they are for JVC, they are not used. If someone has a TV or projector that supports an RS-232 command interface they can determine and enter the Hex string to switch to a user mode or picture mode.


MACRO CONTROL:
X ENABLE
SEND ON EVERY SYNC

- The ENABLE checkbox enables or disables the Macros. I have found no reason to SEND ON EVERY SYNC.

HDR10 MODE:

- For now set it to Automatic. This setting will use the macros I described. Semi-Automatic and Custom make use of the additional CUSTOM HDR10 PROFILES macros. You could use these to select user modes based on HDR10 metadata values. I don't use them.

Damn i just left my house but i know my diva came with a bunch of extra cables which i will look for when i get home.. Small chance i might had thrown them away but i believe i didnt.. If by any chance I dont have them i will order the cables you told me to order.. Thank you.

I guess I have missed a lot here. I had to stop using the A1 EDID because it was preventing my Oppo from playing 3d blurays, so since I was going to change EDID and have to reset the ATV setting anyway, I went ahead and caught up on a few firmware releases at least. I forgot how to set automix so I simply clicked the LLDV option and then selected send HDR flags (ATV Only) for LLDV on the HDR tab, and everything seems to work, including for the Oppo. I left audio in the default setting, which was not "full" but the one after it, and I think I am still getting real Atmos and not up-mixing.


Dominic JUST convinced me to drop my Arves curves and use built in ST.2084 after 2 years... Am I to go back to a custom curve now, with custom gamut as well?

Whatever works well for you in HDR10 should work equally well in LLDV, although you may to bump up brightness (Picture Tone in this case) by a notch.

BTW, I did not say ST.2084 is better than custom curve (if properly customized), only that it’s much easier to use and customize.

Beast mode, thank you so much... I think I'm going to upload your HLG color profile when i get home and try it..
Also whats up with the st2084 it looked good as well after i clicked on it after installing your DV color profile.. Didnt have a chance to mess with it but it looked good as well.

As I am not currently forcing LLDV for all content, just stuff that is natively marked from Disc or ATV apps, would I leave my current HDR (BT.2020/ST.2084) alone and create a new user mode that is custom gamut and same ST.2084 settings?

I'm going to have to get on HDFury to work on Aspect Ratio calculations as this will make it harder for me to increase brightness when in Anamorphic mode.


Do I need to create a custom EDID that will follow the A1 settings but permit 3D? If so, how?

You can do that, or just switch the colour profile manually. One limitation of the JVC ST2084 gamma is that you cannot customize it differently for different picture modes.

So rather than type a long explanation of how to modify the DV string I just wrote a quick application to do it and created a spreadsheet version also. The attached zip file contains the compiled app, alternative spreadsheet, and full source code for the app.

Keep in mind that because of the way the data is packed into the string decimal values lose some precision. For the max nits field, the minimum value is 100, and values should be entered in increments of 50 (ex. 200, 250, 500, 550).

Change whatever values you want then click the "Copy" button to copy the string to the clipboard. If you're using the spreadsheet, just replace the last 5 byes of the string in the HD Fury with the values in the "Hex" column.

Use at your own risk

I love watching the updates from Bmandra and Dominic Chan but I want to suggest a tangent that I have been working on:

Dreamliner suggested that I try SDR BT2020 over the DV hack to see what I thought. I then reached out to HDFury in the Vertex 2 thread about getting streaming devices to stream SDR BT2020. EDID 50 seems to force my Apple TV to stream SDR BT2020. I use my DV hack user setting on my JVC RS500 with Gregg Loewen's Gamma setting, adjusted to 2.4 gamma. The color profile with Dominic Chan's LLDV A1 works the best. I have not done any research to explain why EDID 50 seems to have the same red push that I get with my DV LLDV. Sony product was basis for EDID 50? I use the Macro setting to automatically switch between Custom (EDID 50) for my Apple TV and Automix for LLDV for the Panasonic UB820. Both engage at startup using my Harmony hub/remote, switching between devices. Seamless. Shield TV was a no go. (Not sure about my Roku or Fire TV)

The picture is stunning and a lot brighter than my LLDV DV images. I assume I'm missing out on some specular highlights but my overall image is more satisfying. Thanks to Dreamliner for suggesting this direction! Thanks for Gregg Loewen for tips on setting up SDR BT2020.

I will continue to watch the thread for the amazing progress that is happening with decoding the EDID to ultimately brighten up DV images, but, for now, I'm watching SDR BT2020 on the Panasonic UB820 and the Apple TV 4k. Stunning, bright images on my 170" Carada from the RS500.

I am not quite following what you described.

What has been described so far is to use the Sony A1 EDID, to which the ATV4K responds by providing the Dolby Vision option that we can select. With EDID 50, which ATV4K option will you be selecting?

I'm currently using a Linker and EDID 50 is most likely different from what you're using.

HDfury recommended that I use EDID 50 because it forced a source to output to a display that can only do SDR2020. The Apple TV came up as 4K SDR. My settings for Dolby Vision seemed to work. Gamma for my hdr but switched to 2.4. Your, Dominic’s latest color profile. The HDfury Vertex 2 says it is Rec 709 but it is awesome and my Sdr profiles act like they do when I try them on known HDR streams.

Dreamliner suggested that I try SDR BT2020 over the DV hack to see what I thought. I then reached out to HDFury in the Vertex 2 thread about getting streaming devices to stream SDR BT2020. EDID 50 seems to force my Apple TV to stream SDR BT2020. I use my DV hack user setting on my JVC RS500 with Gregg Loewen's Gamma setting, adjusted to 2.4 gamma. The color profile with Dominic Chan's LLDV A1 works the best. I have not done any research to explain why EDID 50 seems to have the same red push that I get with my DV LLDV. Sony product was basis for EDID 50? I use the Macro setting to automatically switch between Custom (EDID 50) for my Apple TV and Automix for LLDV for the Panasonic UB820. Both engage at startup using my Harmony hub/remote, switching between devices. Seamless. Shield TV was a no go. (Not sure about my Roku or Fire TV)

The picture is stunning and a lot brighter than my LLDV DV images. I assume I'm missing out on some specular highlights but my overall image is more satisfying. Thanks to Dreamliner for suggesting this direction! Thanks for Gregg Loewen for tips on setting up SDR BT2020.

I will continue to watch the thread for the amazing progress that is happening with decoding the EDID to ultimately brighten up DV images, but, for now, I'm watching SDR BT2020 on the Panasonic UB820 and the Apple TV 4k. Stunning, bright images on my 170" Carada from the RS500.
I don't see how you can get SDR BT2020 from the ATV4K. It will either output LLDV BT2020, HDR BT2020, or SDR REC709. The only way I could imagine that you see your HDfury reporting BT2020 without reporting HDR is if you have the Disable HDR checkbox marked in the HDfury GUI. In that case it is still HDR, but metadata has been disabled.

Anyway this is off topic for this thread.

I saw your last post where you said it is BT709 and not BT2020. That makes more sense but is still restricting the color gamut to REC709 instead of the wide color gamut of BT2020 that we get with LLDV.

From that post....

HDfury recommended that I use EDID 50 because it forced a source to output to a display that can only do SDR2020.

He meant that this EDID tells the player the display can't do HDR but it can do BT2020. It does not tell the player that it can only do BT2020. All displays can do REC709 and that is allowed with this EDID. There are only a few players than will output SDR BT2020 based on the EDID. They include the Panasonic UB900 but not the ATV4K. The UB420, UB820, UB9000, and Oppo 203/205 have option settings to output SDR BT2020 and don't need an EDID to trigger it.

As to whether SDR BT2020 is better or worse than LLDV, it all depends on the metadata. If the HDR10 metadata is correct, the Panasonic HDR Optimizer can do an excellent job tone mapping to SDR BT2020. If not correct or missing it the results can be mixed. With LLDV, the tone mapping in the player is using Dolby Vision scene by scene metadata. If that metadata is correct, then I would expect the LLDV output to be similar to good SDR BT2020. If not correct, then it is a toss up as to which tone mapping works best with bad metadata. This is why I use MadVR for all my disc tone mapping as it doesn't look at metadata but analyzes each frame - Dynamic Tone Mapping.

With regard to the ATV4K where almost all content is Dolby Vision, I have it output LLDV. To me the Dolby Vision tone mapping to LLDV in the ATV4K is better than its Dolby Vision to HDR10 conversion.

Claw, I could not send you a message so I am hijacking this thread again. Sorry to all of you for that. I would love for anybody to try this with a JVC RS 500. I set my Vertex 2 for EDID 50. I put Apple TV in SDR 4k 24p. The image that I get responds very well to my HDR setting but with gamma 2.4. I get a red push that I used the LLDV A1 color profile from Dominic Chan. Dreamliner suggested some of these settings when I used Panasonic UB820 SDR 2020. Color temp 6500k. I was surprised by how amazing the image was from Apple TV. Try it and fiddle with it. You might find it outputs a very good image. I felt the Apple TV output with these settings was as good or better than my Panasonic UB 820 output with SDR BT 2020.

I agree with Claw that you’re just getting an SDR709 image, as the ATV4K cannot output SDR2020. It may look wide gamut with it if you use the A1 colour profile as all the colours will be “stretched“ to DCI-P3, so the saturated colours will look similar to proper HDR, but there no guarantee that you’re getting correct colour tracking (not likely at all).

And it is to be expected that SDR will look much brighter than HDR, if you use the same colour profile and same iris opening.

I tried sending 350 nit instead of the 900 A1 value, but couldn't see any difference. Repeated it multiple times. Unfortunately, I can't do an immediate compare since both the ATV4K and JVC do a resync after making the change and sending the DV string to my HDfury Diva.

I did a comparison yesterday and was able to see some difference:
https://www.avsforum.com/forum/465-h...l#post59236624

The brighter version used 60 for tMaxPQ which was thought to be 200 nits yesterday, but corresponds to 700 nits using today’s calculator.

I’ve done a fairly quick measurement on my screen and projector, and used the new calculation tool, so it won’t be perfect on all Sony 760/885s, but it does tame the red push significantly on mine.

Code:
eb:01:46:D0:00:45:03:90:92:3E:13:97
Red .6304, .3166
Green .2835, .6196
Blue .1670, .0901

Measurements done with Lightspace and an i1 OEM.

The MaxPQ string seems to wrap around past 1650; i.e., 1700 nits is represented by 00, same as 100 nits.

When you guys are putting in the newer strings, do you set the colour to dci3 or 2020 0n the vertex 2?

Hi Dominic, what DV string are you putting in to the vertex 2 to get the best picture with a JVC projector. I have the X7900 and have tried this string for the 500 nits and find it to be good

eb:01:460:00:45:03:40:86:60:76:8F

Would like to see if you have found a better one and what it is.

25 foot 3.5 mm Audio extension cable to connect from the above cable to the HDfury serial port:



https://www.amazon.com/KabelDirekt-3...1696885&sr=8-6



You can get a shorter one if 25 feet is not needed, or you can connect two extension cables together if the distance from your HDfury to the JVC is longer.





I have attached a screen shot of the Macros tab in my HDfury Diva.



SDR-BT709 (HDTV) for 60P

SDR-BT709 (Film) for 24P



- I have both of these set to DO NOTHING rather than have my JVC switch to my SDR-REC709 user mode. I do this so that the BT2020 filter does not click in and out each time playback of BT2020 material returns to an SDR menu. I watch so little SDR REC709 content that I manually select the user mode when I do.



SDR-BT2020 User 4



- User mode 4 is my SDR BT2020 picture mode. It is configured to use the BT2020 color filter and Gamma 2.4. Source is mainly MadVR playback of UHD discs.



3D

x.v.Color



- Both set to DO NOTHING as I don't watch 3D, and x.v.Color is for older JVC projectors.



HLG-BT709

HLG-BT2020



- Both are set to my User 6 custom user mode. I have a custom HLG curve loaded since my RS500 did not have HLG support like newer models do. I used to get HLG from Directv, but now limited to YouTube HLG videos.



HDR10 User 5



- If you have two custom curves, this is the user mode where you have your 4000 nit curve configured, otherwise set it to your single curve user mode.



HDR10-Opt User 2



- This is where you set the user mode where you have your 1000 nit or similar custom curve configured. Or to your user mode where you have your single custom curve loaded.



HDR10-Rec709 User 2



- This is where you would configure a user mode for HDR10 REC709. I have never seen such a signal and don't have a user mode configured for it. I just set it to the same user mode as for my 1000 nit custom curve. I could just as well set it to DO NOTHING.



LLDV User 3



- This is the new macro added to the latest generation of HDfury devices (Vertex2, Diva, and Maestro). This macro will send the RS-232 command to the JVC to switch to my custom user mode configured for LLDV.

- Note that if you have the original Vertex, it does not have this LLDV macro. When the Vertex sees LLDV it treats it as SDR BT2020 and will send the command to switch to your SDR BT 2020 configured user mode. If you don't have a SDR BT2020 user mode because you never have such content, you can enter your user mode for LLDV into the SDR BT2020 macro.



Each time the HDfury sees a content type change, it will execute the appropriate macro for the content type. The macro will send the proper RS-232 command to the JVC to select the configured custom user mode. If the macro is set to DO NOTHING, the macro will not send any command.



The CUSTOM HEX strings beside each macro allow the macros to control displays other than JVC. Leave them as they are for JVC, they are not used. If someone has a TV or projector that supports an RS-232 command interface they can determine and enter the Hex string to switch to a user mode or picture mode.





MACRO CONTROL:

X ENABLE

SEND ON EVERY SYNC



- The ENABLE checkbox enables or disables the Macros. I have found no reason to SEND ON EVERY SYNC.



HDR10 MODE:



- For now set it to Automatic. This setting will use the macros I described. Semi-Automatic and Custom make use of the additional CUSTOM HDR10 PROFILES macros. You could use these to select user modes based on HDR10 metadata values. I don't use them.
Hi claw.. what should I set my sync for. I see yours is at 18 seconds?

It depends on the actually luminance you’re getting and the gamma you’re using. I tried 60 (700 nits) and don’t think I’ll go lower than that.
