8K resolution refers to an image or display resolution with a width of approximately 8,000 pixels. 8K UHD (7680 × 4320) is the highest resolution defined in the Rec. 2020 (UHDTV) standard.[1]

8K display resolution is the successor to 4K resolution. TV manufacturers pushed to make 4K a new standard by 2017. At CES 2012, the first prototype 8K TVs were unveiled by Japanese electronics corporation Sharp.[2] The feasibility of a fast transition to this new standard is questionable in view of the absence of broadcasting resources.[3][4] In 2018, Strategy Analytics predicted that 8K-ready devices will still only account for 3% of UHD TVs by 2023 with global sales of 11 million units a year.[5] However, TV manufacturers remain optimistic as the 4K market grew much faster than expected, with actual sales exceeding projections nearly six-fold in 2016.[6]

In 2013, a transmission network's capability to carry HDTV resolution was limited by internet speeds and relied on satellite broadcast to transmit the high data rates. The demand is expected to drive the adoption of video compression standards and to place significant pressure on physical communication networks in the near future.[7]

As of 2018, few cameras had the capability to shoot video in 8K, NHK being one of the few companies to have created a small broadcasting camera with an 8K image sensor.[8] By 2018, Red Digital Cinema camera company had delivered three 8K cameras in both a Full Frame sensor and Super 35 sensor.[9]
