Question: when did the first 4k tv come out

title: 4K resolution
text: Though experiencing rapid price drops beginning in 2013 for viewing devices , the home cinema digital video projector market saw little expansion , with only a few manufacturers ( only Sony as of 2015 ) offering limited 4K - capable lineups , with native 4K projectors commanding five - figure price tags well into 2015 before finally breaking the US $10,000 barrier . Critics state that at normal direct - view panel size and viewing distances , the extra pixels of 4K are redundant at the ability of normal human vision . Projection home cinemas , on the other hand , employ much larger screen sizes without necessarily increasing viewing distance to scale . JVC has used a technique known as `` e-shift '' to extrapolate extra pixels from 1080p sources to display 4K on screens through upscaling or from native 4K sources at a much lower price than native 4K projectors . This technology of non-native 4K entered its fourth generation for 2016 . JVC used this same technology to provide 8K flight simulation for Boeing that met the limits of 20 / 25 visual acuity .
