Graphical error when booting from USB flash install

Hello, I am attempting to install freebsd 11.2 on a lenovo laptop. When booting the initial screen render fine, but after selecting boot multi user this happens.

the installer starts but can't be read.
 
When the Beastie boot menu comes up go to loader.
Try to run sc(4) instead of the normal vt(4). Some boards need it.

#3] Escape to loader prompt
OK
set kern.vty=sc
boot
Then hit enter key.

If that works you can make it stick with this command after installation:
echo kern.vty=sc >> /boot/loader.conf
 
I have seen that on one laptop as well. If I remember correctly the resolution is not found out correctly. You can use a workaround and query modes in the loader(8) prompt by gop list. In my case I used the most likely parameter by gop set 8. That should end up with a proper resolution. boot starts the boot process. To make it permanent after installation add the line to /boot/loader.rc.local or create the file if it does not exist.
