            Bug ID: 288373
           Summary: Can't adjust resolution in vt for single monitor in
                    multi monitor use
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: ports-bugs@FreeBSD.org
          Reporter: pyrus@bsdmail.com

This is when using multiple monitors and using vt in BIOS setting rather than
with UEFI. I attempted to change the resolution of one monitor rather than
both, and this didn't work.

/boot/loader.conf for example
kern.vt.fb.modes.HDMI-1="1280x720"

Another related issue is that, the connector name doesn't show when typing
dmesg with assistance from the grep command. Looking into /var/log/Xorg.0.log
shows HDMI-1. However, this setting isn't working. This may possibly only have
to do with using vt on a BIOS setting.
