HDMI port not detected

[aussa]

Hi, I use Debian Wheezy in a ASUS N53JF with a nVidia GT 425m. In order to use the graphics acceleration I installed bumblebee (http://suwako.nomanga.net/). Even before installing bumblebee the HDMI port was not working. This is the xrandr output:

Code: Select all

Any help to make it work will be very appreciated. Thank you in advance.
