Sony PVM-4300
The Sony PVM-4300, also known as the KV-45ED1, is a cathode-ray tube monitor released by Sony in 1989. The PVM-4300 has the largest CRT picture tube of all time, with a 43-inch diagonal display and a weight of around 200 kilograms.[1][2] Development of the display was finished in September 1987, with it becoming available in Japan in April 1989 and the United States in 1990. After documentary evidence of the monitor declined following its release, the monitor became famous among CRT enthusiasts. In 2024, one of the last known PVM-4300s was recovered by hardware modder Shank of the Shank Mods YouTube channel. HistoryDevelopmentIn the late 1980s, Sony began development of a 43-inch display tube, which was finished in September 1987. The PVM-4300 was unveiled in a 1988 issue of the Japanese DIGIC magazine as well as in American tech-related publications, with no official release date given.[3][4] Release and salesThe PVM-4300 was first released by Sony in Japan in April 1989 for an introductory price of ¥2.6 million in Japan.[5][6] Around twenty sets were imported into the United States around January 1990, with an introductory price of $39,999.99[7] ($98,317 in 2023). It was described as being aimed at the "videophile and elite-consumer market."[8] In April 1990, Jim Palumbo, president of Sony's Consumer Display Products Co., reported to the Sun Sentinel that only three PVM-4300 sets had been sold in the United States up to that point,[9] although a month earlier he had reported to Chicago Tribune that "at least four or five" had been sold.[7] .jpg) ObscurityFollowing its release in the late 1980s, photographic and documentary evidence of the monitor began to dry up, which, in addition to its limited release, gained it a somewhat legendary status among enthusiasts of CRT monitors.[10][11] RediscoveryIn December 2024, hardware modder Shank of the Shank Mods YouTube channel tracked down a functional PVM-4300, one of the last, in the second floor of a noodle restaurant in Osaka, Japan.[10] Shank, with the help of another person and a company involved in shipping of industrial equipment, arranged for the monitor to be shipped to the United States. It was throughly tested and serviced upon arrival.[10][11] Specifications_with_cat.jpg) The PVM-4300 has a 45-inch (with a 43-inch viewing area) colour Trinitron Microblack CRT picture tube, which is the largest ever produced.[5] It is capable of displaying a standard interlaced image as well as a 480p picture at a 60Hz refresh rate, using improved-definition television (IDTV), which used a digital frame buffer to deinterlace video.[12] The monitor contains two RGB inputs at 15.75 and 31.5kHz to allow for native 480p inputs.[13] According to CRT Database, the unit weighs 199.6 kilograms (440 lb), and measures at 105 x 92.5 x 76.7 cm (41.3 x 36.4 x 30.1 in).[14] ReceptionEric Zorn of the Chicago Tribune expressed both his astonishment at the size and of the cost of the monitor, writing: "This TV set is to your TV set what your TV set is to an old Popsicle stick in the gutter with ants on it."[7] A review in the Sun Sentinel expressed a similar sentiment to its cost yet praised the monitor for its "brightness, clarity and sharpness of color."[9] A 1989 issue of Video Review described it as the "best-looking, big-screen set we've ever seen", but also said it's "designed more as a statement than a conventional product."[15] Shank, after acquring the set in 2024, described it as looking "incredible" in person.[11] Gallery
