EDID thread (RTD1619DR players)

Sorry - I missed that you were using SDR in BT.2020.

Yes of course, you can use "Highest SDR Rec.2020" and an EDID is not required in that case. That uses the Realtek engine to tone map and doesn't touch the colour space. I agree, it would be better than HDR on that PJ.

Can you explain the problem a little more clearly - changing receiver shouldn't change anything (assuming it's an upgrade!).

It's also worth trying the EDID and VS10 SDR though - this has much better tone mapping than the Realtek engine.

 

Hello Mark, yes the receiver is an upgrade with 2.1 features. Clearly I don't need 2.1 so I only used enhanced mode for 4k HDR and not the upgraded 8k mode on all of the sources. I have an Apple 4k that is set to 4k SDR that plays flawlessly in that mode. With the Zidoo I always set it up to match frame rate and HDR - SDR and SDR BT2020 for all content. The first few times I did that I had no issues playing back content. I now see that every time I power on the device the settings are changed and when I go to change the HDR - SDR the screen turns rainbow colors and glitches out. I have to then change from auto resolution to 1080p on the next start up and that allows me to tick the HDR-SDR and then switch back to 4k resolution to get it to work. That workaround seemed to be effective but now it's a tossup if it works and as you know I'm not going to try multiple times with a projector. I had heard that putting in an EDID effectively saves the settings? I was thinking that I could somehow put in the settings I mentioned and then hopefully not have to worry about the projector glitching out

 

I'm not sure what you mean by "I always set it up to match frame rate and HDR - SDR and SDR BT2020 for all content"

And "that allows me to tick the HDR-SDR"

It's the HDR-SDR bit that's confusing me. There's no such option to select or "tick".

 

If you go into the settings on HDR there is section in which you can change it to HDR - SDR rec 2020 limited also a tab in the picture as you can see for HDR - SDR looks like I can't upload pics but it's there if you go into the settings

 

The only similar option is "HDR to SDR" which only allows you to change picture parameters like Brightness & Contrast (which you shouldn't!).

I'm still unclear what's actually happening.

 

I uploaded the edid you recommended. The PQ looks great and I think I figured out the issue. The problem is the receiver and some sort of handshake issue. The glitch happened again after viewing a movie and returning to the main screen. I hit the resolution button on the remote and voila the picture came back.

 

Wasn't an ISO or BDMV was it?

You have to be careful with the resolution button because it cycles, so the resolution/framerate it lands on depends on where it started.

 

That is good information to know. Hitting the resolution is the only thing that gets it to go back to the main menu otherwise it's a purple haze mess. I generally will hit the info button as a movie is starting to make sure it's in the right framerate. The movie I watched last night was not a ISO or BDMV it was an remux mkv. Thanks for all of the help and input

 

I’m using the HDFury Vertex 2 with the Zidoo Z10 Pro with the EDID available in the settings connected to a JVC projector.

If I use BT2020NEW 1000nit LLDV, available to download in the fisrt post of this discussion, what will be the main differences in terms of image quality?

 

If you mean compared to the Zidoo built in EDID then the BT.2020 colour primaries are slightly more accurate but because of the number of bits allocated to their definition in the Dolby Block, I doubt you'd see any huge difference. Maybe on a test pattern. Side by side.

 

I'll test it tonight
And what about the EDID "Full + BT2020NEW 1000nit LLDV +HDR10+"?

 

That's exactly the same but with the addition of HDR10+ support.

(HDR10+ is just a switch - on or off)

 

For a Sony 695es what would be a good EDID? The 400 nit LLDV or 10,000 LLDV not sure what difference could be. I would assume the 400 nit would be better but maybe it's not?

 

As a rule of thumb the 1000nit is generally better because that's the nit level most content is mastered to (well, it's not really, it's complicated, but it's kind of the standard!).

When you set the Dolby Block to 1000nit, the Dolby decoder tone maps to 1000nits (if required - depends on content) and that's kind of the standard for LLDV. Then when the projector gets hold of it and is told the signal is 1000nit HDR10, the projector then maps the rest of the way to its native output (probably around 100nits).

The key is to match the Dolby nits value to the HDR10 nits value so it depends how that last bit is done - with an HDFury you specify the nits value in the HDR message but if you're just using a manual "HDR mode" in the projector, it depends how that processes the signal - probably at 1000nits as that is a logical assumed value.

 

Great thank you Mark you knowledge is invaluable

 

Hi

Could somebody gives me a link to a working EDID file for the Epson 5040ub (or TW9300).
The link posted in this thread is broken.
I would like to use the LLDV with my projector.
Thank you !

 

Wait for @Markswift2003 reply. He'll will guide you in details!!

 

First page of the thread.

Actually just checked and the 5040 is only HDMI 1.4 with a hack to add HDR metadata.

@Maxlam , can you post your EDID and I'll add LLDV.

 

Hi Mark

Thanks.
Well, currently I am not using any specific EDID. I just would like to get one working, taking the bandwidth limitation of the 5040ub into account.
I've seen you helped some users with posting files on MegaUpload

 

No problem - post your EDID with the Zidoo connected as you normally use it and I can add LLDV.
