Laptop computers have started using the HDMI interface more and more as a means of output. When you connect the laptop to a supported HDMI device, the laptop can display its contents to the external monitor. While outputting video is not a problem for most laptops, accepting video from other devices, like a Sony PS3, is something not many laptops can do. The only way to play a PS3 using a laptop's screen is if the laptop supports HDMI input.

Plug the HDMI cable into the rear of the Sony PlayStation 3.
Turn the laptop on, and wait until it reaches the home screen of its operating system.
Connect the other end of the HDMI cable to the laptop's HDMI input port. If the laptop has two separate HDMI ports, one for input and one for output, the PS3 can display its contents only via the input port.
Turn the PS3 on, and the laptop's screen should begin to flicker as it changes the screen source to the PS3's frequency. The PS3 output content will be displayed on the laptop screen.
