In 2007, SMPTE issued Standard 2036, Ultra High Definition Television — Image Parameter Values for Program Production.
This defined two standards: UHDTV1 and UHDTV2, or 4K and 8K.
UHDTV1 has twice the number of pixels of 1080 HD, and UHDTV2 has four times. (See Table 1.)

搞不好下個世代還是會先玩4K。
除非科技發達到資料傳輸頻寬是用不完的狀態,或是有什麼大跳躍的壓縮編碼技術吧....。
