NUC7CJYH - 1080p@23.98Hz not possible

DerSchnelle · January 26, 2019 at 3:58 PM

Hello guys,

I'm having problems with my NUC7CJYH. I just can't get it to set the resolution to 1080p@23.98Hz in libreelec.

Here are the facts I have now:

- 1080p@23.98Hz no signal with LibreELEC (milhousebuild 0125) (debug log: http://ix.io/1z8i)

- I think the problem starts at: 19:17:59.629 T:140112050014336 DEBUG: RecreateWindow - current output: HDMI1, mode: 0x18c, refresh: 23.976

19:17:59.629 T:140112050014336 DEBUG: OnLostDevice - notify display change event

- all other 1080p refreshrates work with LibreELEC

- 1080p@23.98Hz works with Win10 Kodi

- 2160p@23.98Hz works with LibreELEC (milhousebuild 0125)

- xrandr pastebin: http://ix.io/1ysb

I just don't know what I can check or change anymore, hopefully somebody can give me hint.

I also posted this in LibreELEC Testbuilds for x86_64 (Kodi 18.0), but till now nobody answered me.

It should be possible. Have you applied all necessary resolutions/fps combo's in the Whitelist option?

Yep, I have selected all resolutions and framerates in the whitelist including 1080p@23.98.

The strange thing is that all other refresh rates and resolutions work just fine.

Try kernel 5.0-rc3 build

Try kernel 5.0-rc3 build

Because kernel 5.0-rc3 is the newest one?

Sorry... I think some thick soup suddenly got in my eyes.

Sadly no luck with the new kernel.

Here is the debug log: http://ix.io/1zis

I tried with the other HDMI-output and with the new 0126-build, but still no luck.

Hey guys, it's me again.

I just updated to 0128 without any improvements, but I also checked the other refresh rates on 1080p and noticed, that only 1080p@60hz, @59,94Hz and @59Hz work, the other refresh rates don't work either.

Does this help in any way?

Found a similar issue with Gemini Lake here.

So I understand the problem could be kernel related? Shouldn't the fix merged be in the newest kernels?
