Xbox 360 portable outputting component video
Originally I didn’t think you could have the HDMI connected and still get a component signal (which is required to have any sort of “external output” on an HDMI-enabled 360 laptop) but I have found the way. For some boring discussion and the how-to, check the rest of the story. I figured I should post this stuff in case it’s of use to anybody.
