Hi,
I just upgraded from Libreelec 8.2.5 to 9.0.0 and right after the second reboot my tv just gave the message "unsupported video format" and was blank.
My libreelec box is connected via HDMI to an av receiver which is connected to my tv.
Have there been any changes in LE 9.0.0 regarding the video resolution or anything like that?
