--- Comment #1 from Marcel Moolenaar <marcel@FreeBSD.org> ---
If I can read the screen correctly, it looks like the resolution is 1366x768,
with a stride of 1366 and a color depth of 32 bits per pixel (or 4 bytes per
pixel).
The console output seems to be using a stride that's just wrong. Since the
stride is coming from UEFI, it's hard to think of a reason why the kernel would
do this.
Have you tried updating the firmware?
--- Comment #2 from Oliver Pinter <op@freebsd.org> ---
Yes, today I updated to latest bios from HP, but the issue still exists.
How could I extract these information without serial port or change the
settings in loader or kernel?

loader with 'gop' command
--- Comment #4 from Marcel Moolenaar <marcel@FreeBSD.org> ---
(In reply to Oliver Pinter from comment #2)
I committed revision 287299 (-current), that adds a 'gop' command to the
loader. I attached a pre-compiled EFI loader with this command to this PR.
Can you run 'gop get' and 'gop list' and add the output to this PR?
Also: can you try different modes (if possible) and see if that makes a
difference?
