So it seems that in fixing the previous black screen problem we have introduced a new black screen problem for users with 4k TVs.
Like the blackscreen issue on 8.95.4 this is an issue with the information provided by the TV to your device, and how CE uses that information. So when CE receives incorrect information about your TVs capabilities, it gets confused and thinks the display mode requested by kodi is not possible, even when it is. Resulting in a black screen/no signal.
As stated before the shear number of different models of TVs, combined with the number of different AVR that could be used with them makes this impossible to test on every possible combination before release.
If users affected by this can post the make and model of TV, and if the TV has HDR support, and state if you have an avr between your device and the TV
also the contents of
would be helpful.
also if you using an AVR or other device between your device and the TV, try directly connecting your device to the tv, and providing the out put of the previously mentioned file while directly connected to the TV.
edit: and if you haven’t already posted one a kodi log, and the output of dmesg might be helpful as well. (though remember to use pastebin or similar method for the log file and dmesg output since they can be pretty big and make the thread hard to follow when pasted directly into a message. )
