Kebul na DisplayPort
Tsarin haɗin nunin dijital ne mai inganci wanda za'a iya haɗawa da kwamfutoci da na'urori masu saka idanu, da kwamfutoci da gidajen sinima na gida. Dangane da aiki, DisplayPort 2.0 yana goyan bayan matsakaicin bandwidth na watsawa na 80Gb/S. Daga ranar 26 ga Yuni, 2019, ƙungiyar daidaitattun VESA ta sanar da sabon ƙayyadaddun ƙayyadaddun bayanai na DisplayPort 2.0, wanda aka haɗa shi da Thunder 3 da USB-C. Zai iya biyan buƙatun 8K da fitarwa na nuni mafi girma. Shi ne babban sabuntawa na farko tun bayan yarjejeniyar DisplayPort 1.4.
Kafin haka, jimlar bandwidth na ka'idar DP 1.1, 1.2 da 1.3/1.4 shine 10.8Gbps, 21.6Gbps da 32.4Gbps bi da bi, amma ingantaccen ƙimar shine 80% kawai (lambar 8/10b), wanda ya kasance da wuya a cika buƙatun ƙuduri mai girma na 6K da 8K, zurfin launi mai girma da kuma saurin wartsakewa mai girma.
DP 2.0 yana ƙara yawan bandwidth na ka'idar zuwa 80Gbps, kuma yana amfani da sabon tsarin ɓoye bayanai, 128/132b, wanda ke ƙara yawan aiki zuwa 97%. Ainihin bandwidth ɗin da ake amfani da shi yana kaiwa 77.4Gbps, daidai yake da sau uku na DP 1.3/1.4, kuma ya wuce yawan bandwidth na ka'idar HDMI 2.1 na 48Gbps.
Sakamakon haka, DP 2.0 zai iya tallafawa HDR 8K/60Hz cikin sauƙi, >8K/60Hz SDR, 4K/144Hz HDR, 2×5K/60Hz da sauran tsare-tsaren fitarwa. Ba wai kawai zai iya tallafawa kowane mai saka idanu na 8K ba tare da matsi ba, har ma zai iya tallafawa zurfin launi na 30-bit (fiye da launuka biliyan ɗaya). Aiwatar da HDR 8K.


DisplayPort 2.0: Thunderbolt 3, UHBR, da kebul na bayanai marasa aiki
Dangane da layukan bayanai, DP 2.0 a zahiri yana gabatar da hanyoyi guda uku daban-daban, inda kowace hanyar sadarwa ta samar da bandwidth a 10Gbps, 13.5Gbps da 20Gbps bi da bi. VESA ta kira shi "UHBR/Ultra High Bit Rate". Dangane da bandwidth, ana kiransa UHBR 10, UHBR 13.5, UHBR 20 bi da bi.
Asalin bandwidth na UHBR 10 shine 40Gbps, kuma ingantaccen bandwidth shine 38.69Gbps. Ana iya amfani da wayar jan ƙarfe mai wucewa. Aikin takardar shaidar waya na DP 8K na baya ya haɗa da shi, wato, wayar bayanai ta DP wacce ta wuce takardar shaidar 8K ta cika buƙatun amincin sigina na UHBR 10.
UHBR 13.5 da UHBR 20 sun bambanta. Asalin bandwidth sune 54Gbps da 80Gbps, kuma ingantaccen bandwidth shine 52.22Gbps da 77.37Gbps. Ana iya amfani da wayoyi masu wucewa kawai don watsawa ta ɗan gajeren lokaci, kamar docking na littafin rubutu.
