I have a media box HK1 RBox X4 with S905X4 chip running the latest CE-NO nightly. Sometimes I want to be able to keep the media box on while turning the TV on and off. If I turn the TV (model Hisense 55Q8) on first before turning the media box on, everything works perfectly (display resolution and CEC). However if I turn the TV on with the media box turned on, CEC does not work properly and also just very occasionally the TV display remains black. I have turned on the “use dump EDID” setting on coreelec, as a step to maybe overcome the problem. But I am struggling to find any instructions on how to actually dump the EDID and where to place the dumped EDID. I have looked at the libreelec wiki for EDID, but the instructions there are for Intel/AMD or nvidia GPU. Can someone point me to a set of instructions to dump the EDID of my set-up, where to place the dumped EDID and how to load the dumped EDID. Or am I barking up the wrong tree to try solve my CEC question
loss of CEC = loss of active route, not going to be solved by EDID
i overcome the CEC issue by starting / stopping Kodi on hdmi active state
try when TV off:
ssh → “systemctl stop kodi”
try when TV back on:
ssh → “systemctl start kodi”
loss of resolution is a renegotiation problem where CE (probably Kodi itself) rechecks HDMI when it’s unplugged, very likely going to resolve with the above
