Iintambo zeDisplayPort
Ngaba umgangatho ophezulu wokubonisa ujongano lwedijithali onokudityaniswa kwiikhompyuter kunye nabahloli, kunye neekhompyuter kunye neethiyetha zasekhaya.Ngokubhekiselele ekusebenzeni, i-DisplayPort 2.0 isekela i-bandwidth ephezulu ye-80Gb / S.Ukusukela nge-26 kaJuni, ngo-2019, umbutho osemgangathweni weVESA ubhengeze ngokusesikweni iDisplayPort 2.0 yomgangatho wokuhanjiswa kwedatha, edityaniswa ngokusondeleyo neThunder 3 kunye ne-USB-C.Iyakwazi ukuhlangabezana neemfuno ze-8K kunye nemveliso yezinga eliphezulu lokubonisa.Luhlaziyo lokuqala oluphambili ukusukela kwi-DisplayPort 1.4 protocol.
Ngaphambi koko, i-bandwidth iyonke yethiyori ye-DP 1.1, 1.2 kunye ne-1.3 / 1.4 yayiyi-10.8Gbps, i-21.6Gbps kunye ne-32.4Gbps ngokulandelanayo, kodwa izinga elisebenzayo laliyi-80% kuphela (ikhowudi ye-8 / 10b), okwakunzima ukuhlangabezana neemfuno I-6K kunye ne-8K isisombululo esiphezulu, ubunzulu bombala obuphezulu kunye nezinga eliphezulu lokuhlaziya.
I-DP 2.0 yandisa i-bandwidth ye-theory ukuya kwi-80Gbps, kwaye isebenzisa indlela entsha yokufaka ikhowudi, i-128 / 132b, eyandisa ukusebenza kakuhle kwi-97%.I-bandwidth yangempela esebenzayo ifikelela kwi-77.4Gbps, ilingana namaxesha amathathu i-DP 1.3 / 1.4, kwaye idlula kakhulu i-bandwidth ye-theory ye-HDMI 2.1 ye-48Gbps.
Ngenxa yoko, i-DP 2.0 inokuxhasa ngokulula i-8K / 60Hz HDR,> 8K / 60Hz SDR, 4K / 144Hz HDR, 2 × 5K / 60Hz kunye nezinye iifomathi zokuphuma.Ayinakuxhasa kuphela nayiphi na imonitha ye-8K ngaphandle koxinzelelo, kodwa inokuxhasa ubunzulu bombala we-30-bit (ngaphezu kwebhiliyoni yemibala).Sebenzisa i-8K HDR.
I-DisplayPort 2.0: I-Thunderbolt 3, i-UHBR, kunye nentambo yedatha ye-passive
Ngokwemigqaliselo yedatha, i-DP 2.0 ngokwenene yazisa iindlela ezintathu ezahlukeneyo, kunye ne-channel bandwidth nganye ebekwe kwi-10Gbps, i-13.5Gbps kunye ne-20Gbps ngokulandelanayo.I-VESA iyibiza ngokuba “yi-UHBR/Ultra High Bit Rate”.Ngokwe-bandwidth ngokulandelelana ebizwa ngokuba yi-UHBR 10, UHBR 13.5, UHBR 20.
I-bandwidth yokuqala ye-UHBR 10 yi-40Gbps, kwaye i-bandwidth esebenzayo yi-38.69Gbps.Ucingo lobhedu olungasetyenziswanga lunokusetyenziswa.Iprojekthi yangaphambili yesiqinisekiso socingo se-DP 8K ibandakanya ngokwenene, oko kukuthi, ucingo lwedatha ye-DP oludlula isiqinisekiso se-8K luyahlangabezana neemfuno zemfezeko yomqondiso we-UHBR 10.
I-UHBR 13.5 kunye ne-UHBR 20 zahlukile.I-bandwidth yasekuqaleni yi-54Gbps kunye ne-80Gbps, kwaye i-bandwidth esebenzayo yi-52.22Gbps kunye ne-77.37Gbps.Iingcingo zePassive zingasetyenziselwa kuphela ukuhanjiswa komgama omfutshane kakhulu, okufana nokufaka i-notebook.
