The Panasonic TH-42PZ700U is one of the most expensive 42-inch plasmas on the market, but it's also the best-performing flat panel of its size we've ever tested. The high price can be blamed squarely on its native resolution--it's the first and only 42-inch 1080p plasma--but the picture quality has little to do with all those pixels. Instead, we noted its deep black levels and realistic shadow detail along with a commendably clean image.
