Hi guys ![smile :)](https://forum.libreelec.tv/core/images/smilies/emojione/263a.png)
I don't know why and can't really explain how, but after 3-4 Days without any issue and some hours of playback without issues i think i can safely say, that the issue is resolved, at least for me.
Luckily recently i bought a new TV-Rack. Therefore all the cable connections had to be freshly connected.
After that after a while i realized that the flickering didn't appear any more. I wanted to know why.
As i had the issue before on every single Build from 8.01c - 8.01k, the only thing which made sense, was some Cable connection, probably HDMI.
I was pretty sure, i already had tested different cables and Ports long ago and couldn't resolve the problem this way ...
but probably this was a wrong conclusion?
So i tested all the HDMI ports with 2 different cables, once again, with following result:
HDMI 1,2,4 are working fine so far. ONLY HDMI 3 is producing the issue.
It also doesn't matter, if i activate or deactivate automatic display refresh rate adjustment. Everything is fine on HDMi 1,2,4.
I'm especially saying that, because deactivating refresh rate adjustment resolves the issue also on HDMI3
I don't have a clue why ...
It also doesn't matter if RGB or YUV Output --> all fine
HDMI Port 3 is also set up with identical picture and audio settings, as e.g. HDMI 2. Therefore i think i can eliminate potentially wrong TV-Settings.
Another interesting fact is that HDMI 3 only produces the issue in combination with Mini M8S II and Libreelec (or Android, doesn't matter)
My Raspberry Pi 2 with Libreelec (which meanwhile is connected to HDMI3) is running absolutely fine, as ever.
That's weird, isn't it? Does anybody have any thoughts about this ( at least to me ) very strange behavior?
Probably someone else will also able to resolve the issue like that. I hope so ...
