would also like to mention that the latest LibreElec 11.0.6 would no longer boot or show output on our older TV (nearing 20 years of age) with direct HDMI connection.
The older images 19.5 and 18.9 function just fine on the same TV (especially 18.9 is fluid) , however the newest just wont output any video. It seems the same Rock64 image function however just fine with LibreElec 11.0.6 on a newer Computermonitor.
