I've an HDMI port on my Windows laptop. I often use it as an output port connected to a TV. I need to do the opposite. I would like to know if it´s possible to connect an other hardware (this one send the video through its own HDMI port) on my laptop port in order to use my laptop screen as à display?
The short answer is NO. The LCD on a notebook/laptop can't be accessed with the system's on-board HDMI port. The HDMI port on the notebook/laptop is an output port, not an input port.
