Can anyone take a look at the configuration and settings of my HTPC based on the Asrock J5040 motherboard.
Despite the numerous settings according to howto: https://wiki.libreelec.tv/configuration/edid#custom-edid
after switching to another hdmi / TV port and returning to hdmi: HTPC / LibreElec, I only get a black screen?
and also after turning on HTPC without TV turned on ...

I had nvidia mobo and it worked perfect ... now intel is black magic 
Ps. Unfortunately, I gave up on LE and installed the fork version - AlexElec 19.1-Matrix .... everything works from the proverbial shot 
regards!
