@CForest58, what you want to achieve with that? Do you want to use laptop' screen as a monitor for your XBox, or you want to record your gameplay?
As Barly said - neither of these activities will be possible with just a HDMI cable. Any video-to-USB converter (so that you can plug it into the laptop) will cause delays. While these can be OK for recording, it will kill your gameplay. Been there, done that.
