Iintambo zeDisplayPort
Yindlela yokujonga umboniso wedijithali ekumgangatho ophezulu enokuqhagamshelwa kwiikhompyutha kunye neemonitha, kunye neekhompyutha kunye neethiyetha zasekhaya. Ngokuphathelele ukusebenza, iDisplayPort 2.0 ixhasa i-bandwidth ephezulu yokudlulisa ye-80Gb/S. Ukususela nge-26 kaJuni 2019, umbutho osemgangathweni weVESA ubhengeze ngokusesikweni iinkcukacha zomgangatho omtsha wokudlulisa idatha yeDisplayPort 2.0, edityaniswe ngokusondeleyo neThunder 3 kunye ne-USB-C. Ingahlangabezana neemfuno zokukhupha komboniso we-8K kunye nomgangatho ophezulu. Luhlaziyo lokuqala olukhulu ukusukela kwiprotocol yeDisplayPort 1.4.
Ngaphambi koko, i-bandwidth iyonke yethiyori ye-DP 1.1, 1.2 kunye ne-1.3/1.4 yayiyi-10.8Gbps, 21.6Gbps kunye ne-32.4Gbps ngokulandelanayo, kodwa izinga elifanelekileyo yayiyi-80% kuphela (ikhowudi ye-8/10b), nto leyo eyayinzima ukuhlangabezana neemfuno zesisombululo esiphezulu se-6K kunye ne-8K, ubunzulu bombala obuphezulu kunye nesantya sokuhlaziya esiphezulu.
I-DP 2.0 yonyusa i-bandwidth yethiyori ukuya kwi-80Gbps, kwaye isebenzisa indlela entsha yokufaka ikhowudi, i-128/132b, eyonyusa ukusebenza kakuhle ukuya kwi-97%. I-bandwidth yokwenyani esebenzisekayo ifikelela kwi-77.4Gbps, elingana ne-DP 1.3/1.4 ephindwe kathathu, kwaye idlula kakhulu i-bandwidth yethiyori 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 zemveliso. Ayikwazi nje ukuxhasa nayiphi na imonitha ye-8K ngaphandle kokucinezelwa, kodwa inokuxhasa nobunzulu bombala we-30-bit (ngaphezulu kwezigidi zemibala). Sebenzisa i-8K HDR.
I-DisplayPort 2.0: I-Thunderbolt 3, i-UHBR, kunye nentambo yedatha engasebenziyo
Ngokuphathelele imigca yedatha, i-DP 2.0 ngokwenene yazisa iindlela ezintathu ezahlukeneyo, apho i-bandwidth yetshaneli nganye ibekwe kwi-10Gbps, 13.5Gbps kunye ne-20Gbps ngokulandelanayo. I-VESA iyibiza ngokuba yi-“UHBR/Ultra High Bit Rate”. Ngokwe-bandwidth ngokulandelanayo 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. Intambo yobhedu engasebenziyo ingasetyenziswa. Iprojekthi yangaphambili yesatifikethi sentambo ye-DP 8K iquka yona, oko kukuthi, intambo yedatha ye-DP edlula kwisatifikethi se-8K ihlangabezana neemfuno zokuthembeka kwesignali ze-UHBR 10.
I-UHBR 13.5 kunye ne-UHBR 20 zahlukile. Iibhendi zokuqala ziyi-54Gbps kunye ne-80Gbps, kwaye iibhendi ezisebenzayo ziyi-52.22Gbps kunye ne-77.37Gbps. Iingcingo ezingasebenziyo zinokusetyenziswa kuphela kwiitransmission ezimfutshane kakhulu, ezifana ne-notebook docking.
