No you can't, almost all of the laptop only have video out but not video in. You can get a TV tuner or any other video capturing device to connect your laptop, but the quality would turn out very low.

Xbox is meant for HD, playing it this way would make it low res, losing its purpose.

I suggest you buy a HD capable monitor with HDMI input, they wasn't very expensive nowadays.
