I've been trying to switch my HTPCs from Mediaportal to Kodi for a couple of days. I have problems with my newest Skylake based device.
A Celeron G3900 with Intel HD510-GPU is installed. When LibreELEC starts, the image is only displayed in the upper left corner (XGA resolution). It does not matter whether I connect a monitor via DVI or HDMI. Output device is set to "Default". If I change it to "eDP" all stays the same. If I change to HDMI, the screen gets black until the next reboot. After the reboot the image is displayed again in the upper left corner and the output device is again set to "Default". "Blank other Displays" is activated.
Here are some Log-Files:
