Boot Qubes on second screen

Hey qubes users,
can you please help me to get Qubes to boot?

My Notebook screen probably is black and won’t work anymore.
I can still boot windows on the monitor connected to HDMI. I need to turn on and then connect HDMI
otherwise it get stuck in UEFI and shows only Acer on the monitor.
When I try to boot qubes I can’t see the bootloader neither see I the login screen after some minutes.
Before the screen broke I could boot Qubes without any problem.

Any ideas how I can fix the issue and boot Qubes?

Have version 4.1
