Since libreelec my setup is affected by black screen issue on start/stop of a movie with adjust to refresh rate on

it's a well known problem with denon avr + intel box

A solution that works for 90% is to set gui at 30hz

some example of other users affected by this problem

I have a Denon X2000, could someone confirm with a more recent denon avr problem is solved ?

I had the issue with a Denon AVR-E400, but it's been working fine with a Denon AVR-X4400H.

My workaround on Intel with the Denon AVR-E400 was to edit the EDID to remove the 10-bit and 12-bit color modes, and force the custom EDID by a kernel parameter. The Intel driver negotiates the higher 12-bit color mode even though the source information in X11 is only 8-bit. I noticed the problem only when changing refresh rates with the higher bit rate required for the 12-bit color modes, or for 4K@30 Hz. Keeping it 1080p at 8-bit color or below, and I didn't have the problem.

I didn't have the problem with an integrated Nvidia GT520 GPU on an old Intel Atom Machine. That GPU only negotiated 8-bit color, and wouldn't do 4K which is probably why.

With the Denon AVR-X4400H, I haven't had to edit the EDID. It works fine with the newer Intel GPU.  

Do you rembember which program you used to edit edid table ? 

last time i used getedid command instead of old guide >https://wiki.libreelec.tv/custom_edid#tab__intel But i can't find anymore the firmware folder in libreelec where edid is stored 

thank you for your suggestion 

I read the standard and used a hex editor (xxd). See 331638.
