Last week I received the new Toshiba 51H83 Widescreen RPTV. I love the set but had a couple of questions. When using Avia to perform a basic video calibration I have to turn the brightness up to 83 in order to see one of the moving black bars. The room lighting was moderately dark when I performed the calibration. Is this going to shorten the life of the set? On another note, I currently have a non HDTV cable signal coming into the set and would like to add over the air HDTV however my landlord will not allow me to mount a dish so I was hoping I could capture some OTA broadcasts with an indoor antennae (I am only 5 miles outside of Boston). What equipment would you recommend I purchase in order to receive HDTV in this manner and does it matter that this set now incorporates some funky DVI input in the back and how does that effect any of my decisions? Thanks.
