I have KP-46WT500 and have heard of people turning the gray pillar boxing to black. Through my HDTV receiver it put's black bars on the side and looks much better then gray. I do know that gray is the most neutral color on the spectrum and reduces the chances of burn in, but seeing how I don't use pillar boxing much I'm not worried about it. Does anyone know if it can be done and if so how? I looked around the service menu but didn't want to play with the settings until I know a little more about doing this.
