    Why do some HD channels when not transmitting in HD use grey vertical bars and others black ?

    Grey is better for RPTV's to not burn-in.

    But I have noticed on my set top box that the stb is what inserts the gray bars on channels that broadcast digital, but are 480, 4x3. Channels that are 16x9 in HD resolutions come with the bars from the local station.

    I know grey bars are better...why couldn't all channels use the same color (grey)?....It doesn't matter to me anyway, I could stretch any HD signal with my set. I'm afraid of my wife or kids watching something all day with black bars on the side.
