Almost all TVs have composite input, so for TVs it's not a problem.

Problem here is the laptop. Not many laptop has an input port. On my laptop I can see a HDMI port and a VGA port, but both are output ports, so they're useless anyway. The only option left for me is the usb port, but I don't know if it works or not.

And about x11vnc, could you please share your settings?
