4096 x 2160p 50/60hz

[kodify]

Hi guys. I have a Vero 4k + running osmc kodi. My whitelist doesn’t show any more than 23.98hz and 24hz for 4096 x 2160. Is it a kodi limitation or is it my hdmi cable?
My sony bravia supports 50/60hz at this resolution

To get a better understanding of the problem you are experiencing we need more information from you. The best way to get this information is for you to upload logs that demonstrate your problem. You can learn more about how to submit a useful support request here.

Depending on the used skin you have to set the settings-level to standard or higher, in summary:

• enable debug logging at settings->system->logging

• reboot the OSMC device twice(!)

• reproduce the issue

• upload the log set (all configs and logs!) either using the Log Uploader method within the My OSMC menu in the GUI or the ssh method invoking command grab-logs -A

• publish the provided URL from the log set upload, here

Thanks for your understanding. We hope that we can help you get up and running again shortly.

To upload a log seems very complicated to me and I don’t have an internet connection anyhow.

I would just like to know is if these resolutions are supported by the latest kodi version.
I know that there are only a few for 720p

[grahamh]

My guess is you need to enable the higher mode on your TV, and/or use a HDMI input on the TV that supports higher modes (4k50/60)

[Smurphy]

How do I enable that on my screen?
I have no TV, I have a screen → 436M6VBPAB
It is supposed to make 3840 x 2160 @ 604 Hz? I thought it detected it automatically?

[grahamh]

That depends on the maximum pixel rate (TMDS clock). You won’t see 3840x2160@50/60Hz if your screen can only do that with 8-bit, 4:2:0 output. What does cat /sys/class/amhdmitx/amhdmitx0/edid say?

[kodify]

Thanx for the suggestion grahamh
I have it on the right hdmi
I’m beginning to think kodi doesn’t do higher than 24p for 4096
I checked with the vero lead and an 8k 60 48mbps lead

In this thread from mid 2018 someone had the same problem

Video always output at 24Hz when screen set to 4K

I have set screen resolution to xn OSMC and my Marantz NR1607 is showing the input to be 4k:24Hz which is great for 24p material. However when I play files that are 25 fps I see motion stutters, and the AVR input still says 4k:24Hz. Adjust refresh rate is set to start/stop, sync playback is not enabled. When I set the OSMC screen resolution to 1920x1080p the AVR indicates 1080p:50Hz input when playing 25 fps material. When I enable 4K upscaling in the AVR the output is indicated as 4K:25Hz. Is…

“When I set OSMC UI to 4096x2160p, why does it only offer 24hz and 23.98hz and not all the refresh rates reported by disp_cap? i.e. 2160p25hz, 2160p30hz and 2160p50hz”

Hmm. Which value you need?

So it is the AVR it is showing there.
The screen can definitely do more. The AVR should also not prevent something faster than the 30Hz

I used my roomates wi-fi and followed your instructions
Here are my logs

Edit: log taken off because it has ip address, for privacy

@Smurphy

Which value you need?

That’s all good. Those modes in the 90s are 4k and your TMDS clock goes up to 600MHz. Normally, if the higher HDMI modes are switchable on the display the EDID changes accordingly, but it’s still possible something needs setting on the display. Could you upload full debug logs, please?

[kodify]

Please look at my logs also grahamh

@kodify

I’m beginning to think kodi doesn’t do higher than 24p for 4096

Last time I looked I was getting both 3840 and 4096x2160 at 50 and 60Hz. That log shows you should get 4096x2160 (‘smpte’) at 24, 50 and 60Hz but you are right - Kodi isn’t recognizing them.

We’ll look into it. But you won’t find much content with that resolution and refresh rate.

[kodify]

Please look into it. Thank you

[grahamh]

I just checked, and I can’t get 4096x2160 at 50/60Hz either. Can’t get 25 or 30Hz either (which my TV supports). That must be new. Maybe Kodi devs decided no-one should be using that mode.

Is it important for you?

[kodify]

Hi, thank you for checking. It’s not important if it’s not supported in kodi. As you said its not very popular for content

[sam_nazarko]

These are SMPTE modes and they shouldn’t be used for playback.
I thought they capped out at lower refresh rates anyway.

You shouldn’t use these modes for the UI or for playback.

I actually don’t need it. Just wondered and wanted to participate in the thread, as I was also “impacted” technically speaking.

If you guys want to troubleshoot it, let me know. I am yet to find a movie using a higher framerate to see if it makes a difference though, and for creating the logs.
