Vero 4K with Denon 2300

Hi All, this is my first post on here as I received my Vero 4K yesterday.

Just looking for a bit of advice as this is all new to me.

Is anyone else using there Vero 4K through a Denon 2300 avr?

I have mine through the Denon and connected to my LG Oled 55C6.
I am struggling to play 4K HDR clips as I get poor picture quality.
Vero switches resolution OK but the PQ has lots of flashing pixelated colours where they should’t be.

I have lots of the LG test clips on a usb drive and other clips on a Synology NAS.
It happens on any HDR clip regardless of source and 1080P plays fine.

I have connected the Vero straight to the LG TV and all clips play fine, so I’m sure the Vero is ok.

This would suggest to me that there is either a problem with the Denon or the HDMI cable between it and the TV.

I have tried a different input on the avr and tried a few settings. Video is set to bypass.
The HDMI cable is 5M long and of unknown quality. I have ordered a premium certified 5M cable which will be here in a couple of days.

Both Denon and Vero on latest firmware and I don’t have any other 4K HDR source to try.

Just wondered if anyone has this setup working ok.

Hi,

I don’t use Denon 2300 myself, but I can advise to the following:

  • Make sure the kodi gui resolultion is set to 1080p
  • Confirm that Adjust refresh rate is set to always or on start and stop.
  • If you are using passthrough for audio, make sure sync to display is disabled. (It may be worth trying to disable this either way.

Failing any of that, it probably the HDMI cable; Are you able to test with a shorter one?

Thanks Tom.

Thanks Tom.

Unfortunately I can’t try a shorter hdmi cable unless I drag the TV nearer the Denon.!!

All settings are set as you have suggested.
It’s only 4k hdr that is the problem.

I really hope it is the cable.

When you tried Vero directly with the TV (when 4k HDR was working) did you use the long cable?

When I connected the Vero direct to the tv I used the cable that came in the box.

When I get home I’ll try the long cable out of the Denon in the Vero.

Thanks fzinken for the thought, it should prove whether its the long cable or not.

Hello

Thanks for confirming that the issue doesn’t present itself when connected directly to the TV. If you are familiar with the command line, it would be good if you could post the output of:

cat /sys/class/amhdmitx/amhdmitx0/hdr_cap   
cat /sys/class/amhdmitx/amhdmitx0/edid
  • When connected to the TV (with the TV on and on the Vero 4K source).

  • When connected to the TV through the Denon (with the TV on and AVR on the Vero 4K source).

Is this the receiver that you have: https://www.denon.co.uk/uk/product/homecinema/avreceiver/avrx2300w

Hi Sam, thanks for your input.

Yes that is the avr I have.

Probably a dumb question but I guess the command line commands is via ssh?

Vaguely familiar with that so I’ll give it a go when I can.

Check out:

Normally My OSMC -> Logs would do this so no command line would be needed.
Unfortunately we haven’t added HDR info to the logger yet

Thanks for everyones help and suggestions.
Turns out it was the 5M hdmi cable between the Denon avr and the LG oled tv.
I connected the old cable directly to the Vero and still got the sparklies. I then tried the new cable direct and all is good. So now connected via the avr and all is still good.
Just goes to show what cheap cdmi cables can do!

Hi @donhay

I’m glad to hear it was something as simple as a cable.
