Nā kaula DisplayPort
He kūlana hoʻonohonoho hōʻike kikohoʻe wehewehe kiʻekiʻe ia e hiki ke hoʻopili ʻia i nā kamepiula a me nā monitor, a me nā kamepiula a me nā hale kiʻiʻoniʻoni home. Ma ke ʻano o ka hana, kākoʻo ʻo DisplayPort 2.0 i ka bandwidth hoʻoili kiʻekiʻe loa o 80Gb/S. Mai Iune 26, 2019, ua hoʻolaha kūhelu ka hui maʻamau VESA i ka kikoʻī maʻamau hoʻoili ʻikepili DisplayPort 2.0 hou, i hui pū ʻia me Thunder 3 a me USB-C. Hiki iā ia ke hoʻokō i nā pono o ka hoʻopuka hōʻike 8K a me ke kiʻekiʻe. ʻO ia ka hōʻano hou nui mua mai ka protocol DisplayPort 1.4.
Ma mua o kēlā, ʻo ka bandwidth āpau theoretical o DP 1.1, 1.2 a me 1.3/1.4 he 10.8Gbps, 21.6Gbps a me 32.4Gbps pakahi, akā ʻo ka helu kūpono he 80% wale nō (code 8/10b), he paʻakikī ke hoʻokō i nā koi o 6K a me 8K hoʻonā kiʻekiʻe, hohonu kala kiʻekiʻe a me ka helu hoʻomaha kiʻekiʻe.
Hoʻonui ʻo DP 2.0 i ka bandwidth theoretical i 80Gbps, a hoʻohana i kahi ʻano encoding hou, 128/132b, kahi e hoʻonui ai i ka pono i 97%. ʻO ka bandwidth hiki ke hoʻohana ʻia a hiki i 77.4Gbps, like me ʻekolu manawa o ka DP 1.3/1.4, a ʻoi aku ka nui ma mua o ka bandwidth theoretical o HDMI 2.1 o 48Gbps.
ʻO ka hopena, hiki iā DP 2.0 ke kākoʻo maʻalahi i ka 8K/60Hz HDR, >8K/60Hz SDR, 4K/144Hz HDR, 2 × 5K/60Hz a me nā ʻano hoʻopuka ʻē aʻe. ʻAʻole hiki iā ia ke kākoʻo i kekahi monitor 8K me ka ʻole o ka hoʻopili ʻana, akā hiki iā ia ke kākoʻo i ka hohonu kala 30-bit (ʻoi aku ma mua o hoʻokahi piliona kala). Hoʻokō i ka 8K HDR.
DisplayPort 2.0: Thunderbolt 3, UHBR, a me ke kaula ʻikepili passive
Ma ke ʻano o nā laina ʻikepili, hoʻolauna maoli ʻo DP 2.0 i ʻekolu mau ʻano hana like ʻole, me kēlā me kēia bandwidth kahawai i hoʻonohonoho ʻia ma 10Gbps, 13.5Gbps a me 20Gbps. Ua kapa ʻia ʻo VESA ʻo "UHBR/Ultra High Bit Rate". Wahi a ka bandwidth i kapa ʻia ʻo UHBR 10, UHBR 13.5, UHBR 20.
ʻO ka bandwidth mua o UHBR 10 he 40Gbps, a ʻo ka bandwidth kūpono he 38.69Gbps. Hiki ke hoʻohana ʻia ke kaula keleawe passive. ʻO ka papahana hōʻoia kaula DP 8K ma mua e hoʻokomo maoli iā ia, ʻo ia hoʻi, ʻo ke kaula ʻikepili DP i hala i ka hōʻoia 8K e hoʻokō i nā koi pono hōʻailona o UHBR 10.
He ʻokoʻa ka UHBR 13.5 a me ka UHBR 20. ʻO nā bandwidth mua he 54Gbps a me 80Gbps, a ʻo nā bandwidth kūpono he 52.22Gbps a me 77.37Gbps. Hiki ke hoʻohana ʻia nā uea passive no ka hoʻoili ʻana i kahi mamao pōkole loa, e like me ke kaula hoʻopaʻa puke noke.
