In 1989, Sony introduced the KV-45ED1 (PVM-4300) in Japan, the largest Trinitron CRT ever built with a 43-inch display. Weighing 450 pounds and retailing for $40,000 in the U.S. in 1990, the TV featured IDTV technology for improved image quality by buffering and interpolating frames. This TV was aimed at high-end buyers and required hand-building, making it significantly pricier than smaller models. Few units are known to have survived, and details about the owners remain scarce.
