(Solved) Planet Earth II 4k

That means, same cables, same AVR, same TV, but with N2 2160po@50Hz does not work,
with Minix-U9 it works?

@adamg, @TheCoolest or other CES-supporter: what does this mean?

Let me check again for sure and report back.

From the dispinfo output, it seems that the HDMI input is not detected as HDMI 2.0 capable. 24P movies will switch into 24Hz mode, which is supported by the HDMI 1.4 spec. 25FPS content will make Kodi switch into 50FPS, which isn’t. I’d suggest looking in the AVR and/or TV manual, because some hardware requires HDMI 2.0 to be enabled manually on an HDMI input, be it an AVR or TV.

But why is there a difference if N2 or Minux-U9 is connected to the AVR?
That seems to me that the N2 handles a 2160p@50Hz in another (worse) way than a Minix-U9…

I don’t know why they behave differently, but they use two different kernel versions, and there are differences in the HDMI and other drivers.

So what solved the problem?

If you whitelist all resolutions on N2, is Planet Earth II then displayed in 2160p@50Hz
on your TV or is it scaled down to 1080p?

So I just check the Minix on a new install of stable 9.2 and it worked without adding anything to the white list. On the N2 I had to add all my resolutions to the white list for it to play. The N2 is running nightly’s if that is any help.

On the N2:
Do you say, the white list is empty by default and you add resolutions? Which one?
And after filling the white list the 2160p@50Hz movie is displayed on your TV as 2160p@50Hz?

White list is empty by default. Need to highlight the resolution and hit ok. This then fills the white list box.

This is going to my projector with a fiber HDMI cable and yes adding the 2160@50Hz will indeed display after adding to white list

My chain is N2 (fiber HDMI) to AVR (fiber HDMI) to projector.

here is the display info from Minix playing that same show.

It plays back at 8-bit 4:2:0 instead of 10-bit 4:2:0.
In OP, it also seems that you have force 4:2:2 enabled on the N2.

it may do that on the Minix but on the N2 it will not display at all without setting the white list. On the N2 I also have the force to 8 bit and HDR-SDR (auto) SDR-HDR (off)

Let me load the N2 back up and try it again on default settings.

It could be something that @cdu13a should take a look at.

To me it seems that you’re trying to force feed equipment with HDMI 1.4, that doesn’t support HDR, a HDMI 2.0 signal. The fact it works at all is surprising. I guess that some HDMI 1.4 displays are capable of 4K@50/60 with 4:2:0 chroma.

I reset all back to default and Planet Earth plays.

I go to a 4k movie and no display only sound.
These is with the white list cleared out and all flags for 4k set as default. HDR-SDR 4.2.2 etc…

I rebooted after each setting.

Added all resolutions to whitelist and neither 4k movie or tv show displays only sound.

I don’t think I have anything more to add to what I’ve said in the post above.
You should probably enable force 8-bit, because your equipment can’t handle the bandwidth requirements of HDR and 10-bit at 4K.

The only item that would not support 10-bit 4 k would if anything be a bad hdmi cable from N2 to avr. The rest is 4k certified,.



Only item questionable would be this

So I will replace that cable and see if it will help.

Not all HDMI ports are created equally. Some HDMI ports on a HDMI 2.0 device maybe 1.4 only.
Check your manual. Also check your settings since some devices will configure an HDMI 2.0 port as 1.4 by default for compatibility with older devices, and this needs to be changed in settings. Unfortunately each manufacture calls the settings something different. :frowning:

Which input is the N2 on and which output is your display attached to on your AVR?

Is your display HDMI 1.4 or 2.0? Same goes for its HDMI ports as with the AVR.
Which input is the AVR plugged into on the Display and is that input properly configured?

As long as the HDMI sink is HDMI 1.4 or configured that way, or any device between initial signal source and display you won’t be able to display a 4k 10bit signal.

Projector (from manual)
Terminal Inputs:

  • HDMI® x 1 (HDCP 2.2) <------------fiber hdmi in here
  • HDMI x 1 (HDCP 1.4)
    AVR (From Manual)
    Connect HDMI 1-2 OUT to HDTVs or projectors with HDMI input.
    HDMI 1 OUT supports 4K@60 4:4:4 and HDCP 2.2 compliant <-------Fiber HDMI out here.
    Both HDMI output ports display simultaneously the same audio/video

So I guess I will limit the output in the N2 to 8bit and 4.2.2 inorder to get the 4k to work and turn tone mapping off.
And here I have the Minix once again and it is playing 10-bit
