G'day Jonathan

I have the exact same problem with the same laptop; HP15 with HDMI only external monitor port (no VGA). I have successfully installed Linux Mint 18.1 to dual boot with Win 8.1, and would really like to be able to see the early boot screens for OS selection and trouble shooting.

On mine, the switching between video options in either OS appears to be just F4, without using the Fn key. However, this does not give me anything on the external monitor before the OS has booted; neither Win nor LM18.1.

I wonder if it is in fact possible to get anything out of a HDMI port at the early stages of BIOS booting, and would love to hear from anyone who has achieved this, or knows for sure that the hardware should be capable of it (as opposed to such success with a VGA external monitor port).

When you went in to disconnect the internal screen, did you see anything that suggests there may be a VGA port on the board that may be accessible?

Cheers
