underscanning break-in via xbox

Hey everyone. I just received my Kuro 5080, which I am currently breaking in using the break-in dvd provided by D-Nice in another thread. I'm using my xbox 360 (non-elite) via component cable to play the DVD.


Upon close inspection, I realized that there is a very thin (5 pixel) border around the colored panel shown at any given point on screen. They are a darker hue of whatever color is present on the screen.


I cycled all the "screen size" options on the Kuro, but couldn't make the line disappear. Is this a problem with the xbox?



EDIT: oh, wait. Maybe that border is supposed to be there? Maybe those are inactive pixels? If they are, I'm sorry. That's really dumb of me.
