This works on the Raspbian OS but for OSMC the overscan is corrected for the OSMC spash screen but thereafter, all screens revert to full size resulting in the edges being cut off.
There is no facility on the TV to correct for overscan so I am dependent on the software for corrections.
I have already stated that there is no facility to correct overscan on the TV and no ‘1:1’ settings, only 16:9/4:3/PC/Auto. 16:9 and Auto result in overscan, 4:3 and PC result in broad white vertical bands either side of the picture and still overscan top and bottom.
I have been through all the menus in Kodi and the picture sizing/overscan correct options which were present on an earlier version of XBMC are no longer there.
