I see the Mitsubishi RPTVs carry a warning label suggesting you limit your viewing of images which cause black bars more than 20% of the time. Wide Screen (16X9) or Normal (4X3) both had the warnings on them. Do the other brands carry the same problem but without the warning? I messed with several stretch modes on the 16X9 and I didn't like them. Will I kill every RPTV watching 4X3 without it being stretched? I promise to calibrate the unit properly and take it out of Torch Mode as soon as I get it home.
