Black screen when libreelec starts before tv is on

    Sorry for hijacking this thread but i think my question fits in well here...

    I have a Intel NUC7I3BNK and want to use a custom EDID and followed the instructions from here HOWTO

    to get a /flash/edid.cpio file, but i do not have /flash/syslinux.cfg file

    LibreELEC:/flash # ls

    KERNEL SYSTEM edid.cpio lost+found

    because i am using a multi boot setup (Win10, Ubuntu, LibreELEC) via Grub (legacy BIOS mode) which is configured like this:

    Code
    menuentry "LibreELEC" {
    savedefault
    set root=(hd0,6)
    linux /KERNEL boot=/dev/nvme0n1p6 disk=/dev/nvme0n1p7 quiet
}

    In my understanding i have to configure Grub to start the kernel with the custom EDID.

    So i would adapt my grub config to something like this:

    Code
    menuentry "LibreELEC" {
    savedefault
    set root=(hd0,6)
    linux /KERNEL boot=/dev/nvme0n1p6 disk=/dev/nvme0n1p7 quiet initrd=/edid.cpio drm_kms_helper.edid_firmware=DP-1:edid/edid.bin video=DP-1:D
}

    Is that the right approach for my special system setup?
