DisplayPort tambo
Iyo yakakwirira-tsananguro yedhijitari inoratidzira interface chiyero chinogona kubatanidzwa kumakomputa uye mamonitor, pamwe nemakomputa nedzimba dzemitambo.Panyaya yekushanda, DisplayPort 2.0 inotsigira yakakura yekufambisa bandwidth ye80Gb/S.Kubva munaChikumi 26, 2019, VESA yakajairika sangano yakazivisa zviri pamutemo DisplayPort 2.0 data transmission standard yakatarwa, iyo yakanyatsobatanidzwa neThunder 3 uye USB-C.Inogona kusangana nezvinodiwa zve8K uye yepamusoro nhanho kuratidza kubuda.Ndiyo yekutanga huru yekuvandudza kubvira DisplayPort 1.4 protocol.
Izvi zvisati zvaitika, theoretical total bandwidth yeDP 1.1, 1.2 uye 1.3 / 1.4 yaiva 10.8Gbps, 21.6Gbps uye 32.4Gbps maererano, asi chiyero chakanaka chaingova 80% (8 / 10b code), iyo yakanga yakaoma kuzadzisa zvaidiwa. 6K uye 8K yakakwirira resolution, yakakwira ruvara kudzika uye yakakwirira yekuzorodza mwero.
DP 2.0 inowedzera theoretical bandwidth kusvika 80Gbps, uye inoshandisa itsva encoding mechanism, 128/132b, iyo inowedzera kushanda kusvika ku97%.Iyo chaiyo inogona kushandiswa bandwidth inosvika 77.4Gbps, yakaenzana nekatatu DP 1.3 / 1.4, uye inodarika iyo theoretical bandwidth yeHDMI 2.1 ye48Gbps.
Nekuda kweizvozvo, DP 2.0 inogona kutsigira zviri nyore 8K/60Hz HDR,> 8K/60Hz SDR, 4K/144Hz HDR, 2×5K/60Hz uye mamwe mafomati anobuda.Haisi chete inogona kutsigira chero 8K yekutarisa pasina kudzvanywa, asi inogona zvakare kutsigira 30-bit kudzika kwemavara (anopfuura bhiriyoni remavara).Shandisa 8K HDR.
DisplayPort 2.0: Thunderbolt 3, UHBR, uye passive data tambo
Panyaya yemitsara yedata, DP 2.0 inonyatso kuunza nzira nhatu dzakasiyana, ine yega yega bandwidth yakaiswa pa10Gbps, 13.5Gbps uye 20Gbps zvichiteerana.VESA inoidaidza kuti "UHBR/Ultra High Bit Rate".Zvinoenderana neiyo bandwidth zvakateerana inonzi UHBR 10, UHBR 13.5, UHBR 20.
Iyo yekutanga bandwidth yeUHBR 10 ndeye 40Gbps, uye inoshanda bandwidth i38.69Gbps.Passive copper waya inogona kushandiswa.Iyo yapfuura DP 8K waya certification purojekiti inoisanganisira iyo, kureva, iyo DP data waya inopfuudza 8K chitupa inosangana nechiratidzo chekuvimbika zvinodiwa zveUHBR 10.
UHBR 13.5 uye UHBR 20 zvakasiyana.Iwo ekutanga bandwidths 54Gbps uye 80Gbps, uye anobudirira bandwidths ari 52.22Gbps uye 77.37Gbps.Waya dzePassive dzinogona kungoshandiswa pakufambisa kwechinhambwe chipfupi, senge dhizaini rekunyorera.
