LE 8.95.002 is installed on a Wetek Play box. I intend to use this device in headless mode (no monitor attached) and access the GUI by AML-VNC. It worked fine until LE8. However it is not working in LE9 beta. I got black screen via VNC connection.
Finally I performed a hard reset and found that the screen is black if the HDMI is not connected at boot but connected a bit later. The system is up and running, I can even hear the Kodi GUI clicks if I use the remote but the screen is black on the connected monitor. I can reproduce this issue with default configuration of LE, no add-on installed, nothing configured.
If the HDMI is already connected when the device boots then everything is fine. If it is not connected before boot then I cannot get picture later.
Update: Tested again with LE 8.2.5. It works fine. It is a degradation in in LE 8.95.002
