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. > Thanks in advance, > O.
