PVM-4300, also known as the KX-45ED1 in Japan, is presumably the largest CRT tube ever produced. It was sold in 1991 for $40,000 (2,430,000 Yen) with a variant — the KX-45ED1T with a VT-X5R tuner built in — for ~$41,481 (2,520,000 Yen) | |||

PVM-4300, also known as the KX-45ED1 in Japan, is presumably the largest CRT tube ever produced. It was sold in 1991 for $40,000 (2,430,000 Yen) with a variant — the KX-45ED1T with a VT-X5R tuner built in — for ~$41,481 (2,520,000 Yen). It has been rumored to have been the huge TV featured in the movie "Camp Nowhere", though it may be a rear-projection TV.
It is an example of an "IDTV" (Improved Definition TV), which uses digital circuitry to deinterlace 480i NTSC video signals to 480p. This was meant to reduce eye-straining flicker and improve image clarity on large size screens. In Japan, Sony called this "Digital Frame Memory TV".
It includes two RGB inputs. The first one is for 15kHz (480i) signals. The second one is for 31kHz (480p) signals and bypasses the digital upconversion circuitry.
There was also a similar 29" model released in Japan, the KV-29ED1. However this model lacks a 31kHz RGB input.
