    I primarily use my Zidoo for 3D, so I never had issues with framerate, but lately I have been also using for other videos, both 23.976p and 24p, and I am continually having the player output in the wrong framerate, 60p.

    I have it set to auto regards EID and resolution, and setting to match framerate etc.

    I don't know what is going on but I just want it to output everything direct.

    I'm at the stage I'm looking at buying something else as this is giving me too many problems now.

    Can you provide a MediaInfo report for one of the files affected?

    It's a long time since I used a Z9S but I never had any framerate issues in the years I used it - in fact it was the first Realtek SOC that came with perfect framerate out of the box.

    BTW, I take it in the menu, 2160p 23 means 23.976? If manually trying to force it?

    Nothing unusual in that file and yes, 23 means 23.976.

    If you want to PM me a link to one of these files (maybe upload to Mega.nz) and I'll fire a up a Z9S here and see what happens...

    OK thanks. So 23 is 23.976. I might try to find a smaller one I have to link.

    I notice on a Z1000 pro with similar issue you posted about an edid issue. The title was "1080p challenge whit Zidoo Z1000 Pro and JVC". I tried posting a link but I got blocked.

    Are you able to elaborate on what the issue is or was? I'm on a Sony 4k Projector, thru an Anthem 1140, and I have zero framerate or resolution issues with all my other sources, disc players, Apple TV etc, just the zidoo, so I can't see any evidence of an edid problem on my side - but possibly an EDID interpretation problem on the zidoo side.

    I was actually looking at upgrading to a Z10 pro or z1000 pro (something I can put a HDD in), but if they can have the same issues, I'm at a loss. I guess I can just go back to what I previously did - just using it for 3D remuxes.

    Yeah - that was something odd with a JVC EDID, but not really the same problem you have.

    If it is an EDID problem you can't change that on the Z9S (without something line an HDFury device). If you get one of the later models with the Realtek 1619 if there are EDID issues they can be fixed with a custom EDID.

    When you have an amp connected, the amp has to automatically adjust the display EDID to add the amp's audio formats.

    99% of the time this works perfectly, but occasionally, because the EDID can only be 256 bytes, there is too much information and some of it gets truncated. Because it's an automated process and there's no intelligence involved, it can simply omit important information.

    I've seen Anthems do strange things to EDIDs in the past - not saying that's definitely the problem, but it's a possibility.

    Hmm, thanks, interesting. So what is the strategy then if it is the anthem? Just power cycle it to force handshaking again? To be honest, I loathe 60Hz material, and if I didn't have to deal with both 24p and 23.976, I'd just set the Zidoo to 23.976 and leave it at that. Too many European Blu-Rays are 24 plus a lot of streamed content.

    If I got a Z10 Pro, the newer chipset, would I have better results? Eg could tweak an EDID somehow as you indicate above?

    So if it was an EDID issue, then yes the new boxes can fix it because you can first of all query the existing EDID to see if it's problematic and secondly, you can fix any issues and load a custom EDID.

    So if you set the Zidoo to 23Hz and "Switch Frame Rate and Resolution" what happens to 24Hz material?

    Out of curiosity, I fired up a Z9S and tried to replicate this.

    It's on fw version v2.3.88 and I added two sources to HT, one with 2K content and one with 4K content in a variety of framerates 23/24/25Hz.

    I left Frame Rate Mode on "Switch Frame Rate and Resolution" and Resolution on Auto (3840x2160p60).

    I tested the following:

    2K23, 2K24, 2K25, 4K23 and 4K24 and all changed resolution and framerate correctly.

    So as a test, try connecting the Zidoo direct to the display and see what happens..

    I'll have to check that. What should happen? If it is 24, should the output on the info page show 24 rather than 23? I can't really tell on my AVR as it will show 24 as it rounds both up...
     
  12. Markswift2003

    Markswift2003 Well-Known Member SUPER Administrator Beta test group Contributor

    My projector does the same - shows 24 for 23.976 and 24, so yes, you need to look at the Zidoo info page which will show you the source file framerate and the output framerate:

    Thanks. If that works then I'll just leave at 23. I don't have any 60hz content, so not an issue. The only two discs with it I'm aware of have 3D that I prefer, so I'd never watch the 4k version again!

    BTW, I got a Z10 Pro now, and am still getting the issues on auto, so I'm wondering what I can do with a custom EDID? I did set it to 23 and that is OK with 23.976 and 24, but I realize I have a few 25p or 50i ones (and on the weekend I actually watched that new Netflix French movie release, AKA, and that one is 25p)

    Ok, so now you have a 1619 model you can access the EDID.

    Can you post it here:

    To Download EDID
    ================

    Settings/Display/Custom EDID/Save EDID

    Save to a USB stick or network location.

    Change the file extension from .bin to .txt to upload to the forum

    (The forum won't accept .bin files)

    OK got it. it seemed to save two though?

    Ok - nothing wrong with the EDID (both files are the same).

    Just to be sure, I loaded that EDID into my HDFury Vertex 2 and that makes my Zidoo behave exactly the same as yours. I could have just loaded into the Zidoo, but loading it into the Vertex means that my Zidoo is not doing anything at all differently to yours.

    As expected, no problem with 23/24/25/29/30/50/59/60Hz content.

    There's no way that the the same symptoms can be carried over from a 1296 box to a 1619 box - they're completely different beasts - so the problem lies elsewhere.

    But, as I say, if I fool my Zidoo into thinking it's in your setup, it behaves itself, so I've no idea what's going on.

    This is bizarre then. If you are saying elsewhere, where else is there?
     
  19. Markswift2003

    Markswift2003 Well-Known Member SUPER Administrator Beta test group Contributor

    Just checking - you have got auto framerate on haven't you?

    Settings/Playback/Auto frame rate/Frame rate mode

    I'm not familiar with that one. I just see this one like in the manual: Settings/Playback/Frame Rate Switch/Frame Rate Mode, and I have that set to "Frame Rate and Resolution"
    https://docs.google.com/document/d/1lfn0L-Hg_7BaDC3vXHvMVN_VCTI4Tj1Y/edit

    I have the frame rate pause set to 3 sec - but oddly when it switches it never seems to pause playback 3 seconds. It was the same on my z9s too - it never paused. I'd have expect that if I started a 3D movie, as soon as it started outputting a 3D signal, it would pause playback waiting for handshaking. It NEVER has.
