The term “8k” refers to the approximate number of 8000 lines of width resolution in the 7680 x 4320 format.
8K UHD is the highest resolution defined in the ITU-R Rec. 2020 (UHDTV) standard as well as the UHDTV2 format defined in SMPTE ST 2036-1 television standard.
Although there have been tests done in transmitting 8k feeds and 8k TVs are already being sold, we are quite far away from watching 8k TV over-the-air, through service providers, or through digital services. However, both Sony and Microsoft have 8k support on PlayStation 5 and Xbox Series X consoles.
