Hōʻike kēia ʻāpana i ke kaula DisplayPort

Nā kaula hōʻikePort
He kūlana kikohoʻe hōʻike kikohoʻe kiʻekiʻe i hiki ke hoʻopili ʻia i nā kamepiula a me nā mea nānā, a me nā kamepiula a me nā hale kiʻiʻoniʻoni.Ma nā ʻōlelo o ka hana, kākoʻo ʻo DisplayPort 2.0 i ka bandwidth hoʻouna kiʻekiʻe loa o 80Gb/S.Mai Iune 26, 2019, ua hoʻolaha kūkala ʻia ka hui maʻamau o VESA i ka hōʻike hōʻike maʻamau hōʻike hōʻike DisplayPort 2.0 hou, i hui pū ʻia me Thunder 3 a me USB-C.Hiki iā ia ke hoʻokō i nā pono o 8K a me ka puka hōʻike kiʻekiʻe kiʻekiʻe.ʻO ia ka mea hou nui loa mai ka protocol DisplayPort 1.4.
Ma mua o kēlā, ʻo ka nui o ka bandwidth theoretical o DP 1.1, 1.2 a me 1.3/1.4 he 10.8Gbps, 21.6Gbps a me 32.4Gbps pākahi, akā ʻo ka helu kūpono he 80% wale nō (8/10b code), he mea paʻakikī ke hoʻokō i nā koi o 6K a me 8K ka hoʻonā kiʻekiʻe, ka hohonu kala kiʻekiʻe a me ka helu hoʻomaha kiʻekiʻe.
Hoʻonui ka DP 2.0 i ka bandwidth theoretical i 80Gbps, a hoʻohana i kahi mīkini hoʻopili hou, 128/132b, e hoʻonui ai i ka pono i 97%.ʻO ka bandwidth hoʻohana maoli ʻia a hiki i 77.4Gbps, e like me ʻekolu mau manawa o ka DP 1.3/1.4, a ʻoi aku ka nui o ka bandwidth theoretical o HDMI 2.1 o 48Gbps.
Ma muli o ka hopena, hiki iā DP 2.0 ke kākoʻo maʻalahi iā 8K/60Hz HDR, >8K/60Hz SDR, 4K/144Hz HDR, 2×5K/60Hz a me nā ʻano puka puka ʻē aʻe.ʻAʻole hiki iā ia ke kākoʻo i kekahi monitor 8K me ka ʻole o ka hoʻopaʻa ʻana, akā hiki iā ia ke kākoʻo i ka hohonu o ka waihoʻoluʻu 30-bit (ma luna o hoʻokahi piliona kala).E hoʻokō i ka 8K HDR.


HōʻikePort 2.0: Thunderbolt 3, UHBR, a me ke kaula ʻikepili passive
Ma nā ʻōlelo o nā laina ʻikepili, hoʻopuka maoli ʻo DP 2.0 i ʻekolu mau ʻano hana like ʻole, me kēlā me kēia kahawai bandwidth i hoʻonohonoho ʻia ma 10Gbps, 13.5Gbps a me 20Gbps.Kapa ʻo VESA iā ia "UHBR/Ultra High Bit Rate".Wahi a ka bandwidth i kapa ʻia ʻo UHBR 10, UHBR 13.5, UHBR 20.
ʻO ka bandwidth kumu o UHBR 10 he 40Gbps, a ʻo ka bandwidth kūpono ʻo 38.69Gbps.Hiki ke hoʻohana ʻia ke kaula keleawe pasif.ʻO ka papahana hōʻoia uea DP 8K ma mua, ʻo ia hoʻi, ʻo ka uea data DP i hala i ka palapala hōʻoia 8K e hoʻokō i nā koi pono hōʻailona o UHBR 10.
He ʻokoʻa ka UHBR 13.5 a me UHBR 20.ʻO nā bandwidths mua he 54Gbps a me 80Gbps, a ʻo nā bandwidth kūpono he 52.22Gbps a me 77.37Gbps.Hiki ke hoʻohana ʻia nā uwea passive no ka hoʻouna ʻana i kahi mamao loa, e like me ka hoʻopaʻa puke puke.
