4K Problems 8.95.6

Having Problems running 4K HEVC files on 8.95.6.
TV doesn’t switch to 4k resolution. Sound is working.

Rollback to 8.95.5 and everything is working fine again.


  • Minix U9H neo
  • Coreelec installed to internal

Works fine here on my U9-H, is your content 60fps?

60 fps and 24 fps / Whitelist activated

So if it is working fine on your Minix U9H, maybe I’ll try to update again and check again.

Reinstalled 8.95.6 and the same Problem. After deactivating 4096x2160p (24 and 23.98Hz)
on the whitelist everything is running fine again.

So it seems that the 8.95.6 is having some problems with recognizing and choosing the correct resolution. Under 8.95.5 with whole whitelist activated everything was working perfect.

Any idea?


You shouldn’t activate the whole whitelist anyway.
Just because your TV supports a lot of resolutions/refresh rates, it’s not a good idea to activate them all.

You should deactivate the following:

  • resolutions higher than 3840x2160
  • resolutions lower than 1280x720
  • 1920x1080/25Hz
  • 1920x1080/30Hz
  • 1280x720/25Hz
  • 1280x720/30Hz

I did that already and it’s working fine. But I’m wondering that there have been no problems with 8.95.5.


Maybe 4096x2160p not supported by your TV. 3860x2160p enough for 4K.

I had the same problem in earlier CoreELEC versions with playback of 3860x2160p HDR content when 4096x2160p resolution was whitelisted. I know that my TV supports it, yet disabling it fixed the problem. So there seems to be something that’s not working as it should regarding playback of 3860x2160p content when 4096x2160p is whitelisted… However, it doesn’t really matter as 3860x2160p is the mainstream resolution used for UHD content.

Kodi sometimes reads the wrong resolution for a video, don’t know if this is a kodi problem or a bad file problem. It’s off by a pixel or two for some videos. Overall the end result of kodi ending up trying to play UHD content at 4096x2160p and failing on some TV’s/AVR’s is not something I’m interested in trying to fix, I don’t have the hardware to test with and it is easy enough to work around it with the whitelist.

Why you want to play 3860x2160p content on 4096x2160p? Your TV resolution is 3860x2160p, my opinion is use that for 2160p, do not use higher resolution. Don’t select it in Whitelist.

@cdu13a, I highly agree with you that the devs should not use time to look into the issue! However, there might be people in the future who will complain about black screen or problems with regular UHD content when 4096x2160p is whitelisted as they don’t know that there is a problem regarding it. Most people think that they should activate all the options their TV support in the whitelist, and not just the resolutions they need and know they are going to use. This was the case for me as I selected all the options Samsung mentioned on their support site regarding the TV. So the whitelist issue is worth mentioning when people have issues in the future with playback of UHD content.

@Blakey, It’s not necessarily about 3860x2160p content. Let’s say that my TV supports 4096x2160p, I’ve content with that resolution and I want to play the content with the correct aspect ratio (1.9:1). That’s mostly not possible by now -I’ve not tried as I don’t have any 4096x2160p content. However, this is not the main concern. The problem is with people who whitelist that resolution since their TV supports it without knowing there are problems regarding it and playback of 3860x2160p content.

To my knowledge, there is no real content with that resolution, and I don’t know any TV model natively supporting it without interpolation.

This whitelist feature was just badly implemented by Team Kodi and should have been done better before it was rolled out breaking the setup of a few thousand users.
It’s not up to CoreELEC/LibreELEC/WhateverELEC to fix it, because it’s clearly a Kodi problem.

Generally, I like the idea of this whitelist function, because I can play e.g. 720p content in its original resolution and let my TV scale the image, which results in a better picture quality.
But the possibility of a wrong configuration is very high.

It’s supported by my TV. But not important. I’m fine with deactivating.

4K TVs have a native resolution of 3840x2160, there’s no point in using 4096x2160 for anything.

U R right. 4K TV have 3840x2160 native resolution. My TV also supports 4096 x 2160p (24, 50, 60 Hz)
