Things You'll Need
Instructions
Turn off your Xbox 360. Turn on your laptop and shut down any unnecessary programs.
Plug the trapezoidal plug of the Xbox 360 VGA HD AV cable into the back of your Xbox 360.
Plug the VGA plug of the cable into the VGA port on your laptop; this port also is shaped like a trapezoid and is likely on the rear of the laptop.
Connect the stereo sound plugs to your laptop, if possible. Alternatively, plug the stereo sound plugs into a set of computer or home theater speakers.
Boot up your Xbox 360. Most laptops will automatically switch the screen display over to VGA when they detect a connection (see Tips).
