How to setup hdr content in vero4k

Since some time ago I started getting hdr content, but my TV (Sony 4k x900) doesn’t switch to hdr content, and actually if I enable it myself it s too shinny. Is there any manual or how to for dummies that helps to enable hdr content in your TV from vero4k


On the supplied remote control, press the HOME button.
Select Settings.
Under the TV category, select External Inputs.
Select HDMI signal format.
Select the appropriate HDMI input.
Select Enhanced format.

Make sure on Vero you have

  • Resolution set to 1080p
  • Adjust Refresh Rate set to Always

I did both and still doesn’t work and my TV is hdr set to auto

Please post a log so we can see if your TV is advertising HDR support.

So what is the solution?

We need more than just the kodi log. Please see:

Actually vero4k is connected to a home cinema maybe its the reason TV doesn’t detect hdr content?

The logs should tell us.

What other logs do you need?

Just upload all logs and send us the URL.

All logs? Which ones ?

@grahamh already provided you link to instructions:

Logs under “Providing diagnostic logs”?

I hope I did it ok

Your TV may do HDR but your AVR does not. Check by plugging vero direct into the TV instead of through the Onkyo.

There is a way round this but it needs some work with the commandline as it’s experimental. Let us know if you are up for that and we can post instructions.

You mean using putty and all that?

I could give it a try

You need to update to ‘staging’. To test this update:

  1. Login via the command line
  2. Edit the file /etc/apt/sources.list
  3. Add the following line: deb stretch-devel main
  4. Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot
  5. Your system should have have received the update.

Login again and type echo 1 | sudo tee /sys/class/amhdmitx/amhdmitx0/force_hdr

Play some HDR material and see if your TV reports that it’s receiving HDR (it should say HDR or PQ).

I also recommend you edit /etc/apt/sources.list again and remove the line that you added after updating. This will return you to the normal update channel.

Just one question:

after adding this line

  1. Add the following line: deb stretch-devel main

How do I save it and jump to run the next command?
