My laptop has an integrated graphics (HD4000) and a nvidia GPU (GT650M). It
also has optimus.
 It has a VGA output, a HDMI output, and the internal LCD.

Using the intel driver, I can use the internal LCD and VGA. Using the
nvidia driver, I can use the HDMI.
To use the nvidia driver, I have to use acpi_call to turn on or initialize
the nvidia card first.

My guess is that my HDMI port is conencted to the nvidia card, and maybe
all the ports on your system are connected to the intel card. It's also
possible that your nvidia card also need some acpi function calls to start.

You may try some linux distro which has the driver for your intel graphics
and check Xorg's log.
