Samsung HLR4677W 46-Inch HD-Ready Widescreen DLP TV
Changes standard definition to high definition (almost)
Excellent picture in both high and standard definition formats. Also best tuner that I have seen, I get hi-def broadcasts from over 70 miles away. This is with an outside over the air antenna, prior to this tv, I was using satellite reciever with over the air tuner and could not get any broadcasts over 50 miles away.
