You should as well as most people on this board should have a TV/monitor that will accept/do 1:1 pixel mapping

1:1 pixel mapping is only relevant when playing 1080p content on a display with a native resolution of 1920x1080.

DVD resolution of 720x480, when upscaled correctly, ends up being ~1964x1080. A band of twenty or so pixels on either side of the upscaled image should therefore not be visible on a 1920x1080 display.

I am aware that many devices upscale incorrectly (720 -> 1920); in these cases it's better to turn 1:1 pixel mapping off and have some overscan.
