I have a Lenovo X1 with a DisplayPort and HDMI ports and it only shows one controller when I type 'lshw -c video' even when I have an external display plugged into the HDMI port. In the display settings, it only shows me what displays are actually connected. So when I have nothing connected, it only shows "Built-in display" while it shows both when I have the external screen connected. Alternatively, could it be because the Lenovo U410 ultrabook has discrete NVIDIA graphics? Which may mean that it's got 2 display controllers: the one onboard the CPU + the NVIDIA one.

I see it has an HDMI port so I guess that is the extra display. I assume if you plug a TV into it you will then see the two displays. Presumably for some reason it thinks there is something plugged in there. I would not worry about it provided you are not getting any problems.

Not as far as I know - it's a Lenovo U410 ultrabook. There is what I think is called "GPT"?
