If I want to connect my laptop, which has a VGA output, to a monitor, I plug a VGA cable into both ends. The output being my laptop, and the input the monitor
VGA output sockets are the same as VGA input sockets however, so what if I want to use my laptop as the monitor, with the video being outputted from somewhere else?
As I said, VGA's output is the same as input, so in theory, I have the hardware in my laptop to do this. But presumably I need some software.
So can I use the VGA port on a laptop as a video input?
(And also, can this be done with HDMI?)
