Hi Michael,

in order to work at boot time, you have to add your edid file to your initrd or
initramfs. Don't know, what distribution you are using, but if it uses dracut,
then you should create a file /etc/dracut.conf.d/99-edid.conf (the filename is
arbitrary, but it must have the suffix ".conf") with the following content:

install_items+=" /lib/firmware/edid/mizapfmon.bin "

and then run mkinitrd.

But as I've said, this didn't fix the issue for me.
