Grub menu on HDMI monitor

[Marcin Snieg]

Dear developers,

I would like a feature in Grub that instead of showing grub's menu only 
on laptop's monitor it would show grub's menu on HDMI monitor when 
laptop's lid is closed. I did not find a solution for my issue on the 
Internet. My configuration is dual boot, laptop's lid closed and 
external monitor attached through HDMI port. When I try to select which 
OS to boot I need to do it without any display.

Please consider my needs,

Best Regards,

Marcin Snieg
