I have a Asus UN42, the HDMI port seems is not working anymore, no signal is sent through this port, tried different cable. I now use the displayport. Is there any command to see what the problem is? Something to know the status of the HDMI port.
xandr produces this output:

Now I'm using a displayport to HDMI cable plugged in my displayport. The HDMI has always worked fine, I was using a HDMI to DVI cable to connect my PC to the display, until suddenly stopped working without a reason apparently..
