[x86] Videos playing in top left quadrant only

    Hey just set up an old Samsung galaxy book 2 as a libreelec machine. I'm also using a pulse eight adapter.

    I've just been trying to play a few 4k videos but they all play like the image I've added here in the top left corner only. It's odd. Any idea how to fix this ?


    Renaming my guisettings as to trigger a new one being generated on restart seemed to fix it. But... i'm wanting to keep my old settings without having to go through all the menus and recreate it ? Is there a way to do this? There must be something in the new GUI settings that has fixed it without taking all the other bits ?

    All help is appreciated,

    See if adding video=HDMI-A-1:1920x1080M@60D to kernel boot params (change HDMI-A-1 to match the DRM connector used) solves the problem? - this will force the intial DRM state to 1080@60. As a general rule it's best to leave the Kodi GUI at 1080p and only switch to 4K when needed for playback, see: https://wiki.libreelec.tv/configuration/4k-hdr. I'll guess Kodi currently has a limit on the GUI being 1080p max but the desktop resolution or underlying kernel DRM layer is trying to use a 4K mode.
