Vontar TX92 black flash

Hi

I have installed CoreElec on my Vontar TX92 (S912 3Gb) box

It seems to run fine but when playing video files it will randomly flash to black screen (audio drops as well)

Any ideas?

If you’re running at 4K/watching 4K video, then it’s likely that your HDMI cable isn’t good enough and causes signal drops.
You need a HDMI HighSpeed Premium certified cable for reliable 4K.

happens with pretty much most content - the resolution is set to 1920x1080i @ 50Hz

I have swapped the HDMI cable without changing anything else - I will report what happens

Swapped the HDMI and works without issue!
