Z9X can't see HDMI 4K setting (update b6.3.0)

I've worked around and can't find 4K display setting. Using HDMI 4K cable connected to HMDI-Arc of Denon AVR-2113 and to a Benq W5700 projector.
Any help or solution?

 

The cable is the answer - two variants - bad contact or cable. Sometimes I have the same problem - I eject the cable, link it again & it's OK - 4K again!

 

Actually I'm using the original HDMI 4K cable included with the Zidoo package. Anyway I'll try to use different one but can't see any setting for 4K in HDMI range/mode to show such option.
Device team:
Zidoo Z9X (firmware b6.3.0)
Denon AVR-2113
Benq W5700 projector
Cables: All 4K, theoretically indicated by the supplier
File: various MKV 4K that I can see in my Samsung 4K

Any other suggestion or checking instruction?

 

You can't see 4K in settings because of edid table - when you disable it you'll see all the settings. Anyway - try another cable, yours may be defective!

 

EDID setting as disable and no 4K options are shown. Cable is 4K certified.

 

See attached details for 10m cable

 

Aren’t 4K60p transmission over passive hdmi cables limited to approx. 3m?

10m is a bit too long for passive hdmi cables to carry signals reliably.

 

I've got a 15M (50ft) contract HDMI cable that we used to import from China by the pallet load that I installed in 2005 when I built the cinema. This was well before even HD was mainstream never mind UHD and that passes 4K60 fine.

Must admit these days they seem to make HDMI cables out of cheese.

Even if the cable struggled with the signal, that wouldn't stop the Zidoo showing them as available.

@Visconti12 - can you go to EDID settings and hit "Save EDID" and post the file here - you'll need to change the extension from .bin to .txt so you can upload on the forum.

I know both your projector and amp support 4K but there must be something strange in the EDID for the Zidoo not to provide 4K settings.

 

Got edid file with no data, just zero. Anyway find it here.

 

Are you sure it will work with active-optical HDMI 8K cable? Any experience in such field?

 

If you go on the HDfury forum, you could be forgiven to think these high bandwidth cables should be 3m, never mind "limited to approx 3m". Mine are 1m - size isn't everything

 

Ok, so if that file is what "Save EDID" produces that, there's something very wrong in the chain. Maybe try connect direct to the projector and see if that works as a test.

Didn't notice earlier, but there's a bit of a clue in the image you sent earlier where it says: "HDR: Not support"

If you connect direct to the projector, you should be able to download the BenQ EDID and use that as a custom EDID if needs be.

It's also possible that the chain is fine and something has gone really funky in the Zidoo, in which case a factory reset would hopefully sort it - either way it looks like the Zidoo can't read the amp's EDID.

 

settings - Display - HDMI mode - Ignore EDID
That's the way to se all options incl. 4K !

 

Thanks to all for your great help!!
Finally I've solved the issue: the bloody pasive HDMI 2.0 from Amazon doesn't work, maybe for 10m length. I've connected the Z9X direct to the Benq projector and it works flawlessly. And tried it in another scenary such as Samsung FrameTV with fine result.
Key: Z9X is quite demanding quality cables for long distance, this case is 10m.
Try: To buy an active optical HDMI Cable UHD - 8K, expensive but most probably worthy value.

 

The really odd thing is the empty EDID - a dodgy cable can't cause that - it can stop certain bandwidths from passing down the cable, but it can't zero an EDID so there's something else at play here too.

Try using the old cable, use Custom EDID and load this EDID.

This one is 400MHz which your cable should easily pass - this will allow 4K60 4:2:0 (but not 4K60 444, 422 or RGB):

(Just updated the EDID thread with this one as it might be useful to others)

 

Sorry but it's too complicate to do it once again. The cable is insert the ceiling of the basement room. At any case, the outcome is the same, through Denon AVR-2113 (HDMI-Arc) or directly. Receives 1080p only. I've no other option to try with a reliable long cable. Once installed, I'll post the outcome!!

 

OK, but I think you'll be needlessly spending money.

 

Thanks Markswift for your great assistance. I've no doubt but thinking that Z9X is really demanding for such issue. Worked around but no solution.
IMO this is an advice for the developers to solve in next firmware versions!!

 

Finally I've changed the cable to HDMI optical fibre 8K and the result is the following scenario:
1) Direct connection from Z9X to Benq W5700: Correct and getting 4K 2160p as photos.
2) Via Denon AVR-2113 to Benq: It starts giving the image for 2-3" then dissapear. Benq try to search video for while with no success, then black screen.
3) Via Denon AVR-2113 to Benq+Sharp Aquos-3D with video splitter: It gives 1080p as photos.
Obviously I need the AVR sound.

EDIDs files also added here.

Any suggestion or shall I wait for future releases to solve such issue?

 

As I said before, the problem is not the Zidoo, it's the EDID and in particular the Denon EDID.

Can you grab the EDID of the Zidoo connected to the Denon connected to the BenQ WITHOUT the Aquos and splitter.
