Making adjustments in the GUI is hard when only the top third is visible...
Edited /storage/.kodi/userdata/guisettings.xml
<resolution>26</resolution><screenmode>00192001080024.00000pstd</screenmode>Now the GUI displays correctly in HD.
UHD video is displayed correctly (full screen)
On my LG Oled TV 55B6V (4K), Kodi is at the bottom third of the screen.
It is attached to an A95x (S905x)
I previously ran 7.0-devel-20161006124814-r23325-g3be647e which had the problem of displaying the video in the top left quadrant. I adjusted the resolution to 1920x1080 to work around that.
