Hello, on my laptop I have this port:
It's for video but I just can't recall how was it called...anyway I was wondering if it was possible to connect it to my arduino so I can exchange data with my laptop.
So I'm asking for directions, in particular links to its datasheet and data exchange protocol...can you help me out?

Looks like a standard VGA DE-15. VGA is an analog interface, so you will need a way to modulate voltages.
I can't see a picture, so I don't know what it is, but if it is a 15-pin VGA connector, then there is a possibility.
How easy or even doable this is I have no idea.
The VGA interface specification includes provision to identify and control (power saving, etc) a monitor through a digital connunication protocol. That protocol is basically I²C.
There may be a way to interface that I²C monitor control signal to an Arduino's I²C interface in some way.
No idea how you'd control it though...
Thank you to both for answers!
