Izintambo ze-DisplayPort
Kuyindinganiso yokubonisa yedijithali enencazelo ephezulu engaxhunywa kumakhompyutha nama-monitor, kanye namakhompyutha nama-home cinema. Ngokuphathelene nokusebenza, i-DisplayPort 2.0 isekela i-bandwidth yokudlulisa ephezulu engu-80Gb/S. Kusukela ngomhlaka-26 Juni 2019, inhlangano ejwayelekile ye-VESA imemezele ngokusemthethweni imininingwane entsha yokudlulisa idatha ye-DisplayPort 2.0, ehlanganiswe eduze ne-Thunder 3 kanye ne-USB-C. Ingahlangabezana nezidingo zokukhipha kokubonisa kwe-8K kanye nezinga eliphezulu. Kuyisibuyekezo sokuqala esikhulu kusukela kuphrothokholi ye-DisplayPort 1.4.
Ngaphambi kwalokho, i-bandwidth iyonke ye-DP 1.1, 1.2 kanye ne-1.3/1.4 yayiyi-10.8Gbps, 21.6Gbps kanye ne-32.4Gbps ngokulandelana, kodwa izinga eliphumelelayo lalingu-80% kuphela (ikhodi ye-8/10b), okwakunzima ukuhlangabezana nezidingo ze-6K kanye ne-8K high resolution, ukujula kombala okuphezulu kanye nezinga lokuvuselela eliphezulu.
I-DP 2.0 inyusa i-bandwidth yethiyori ibe yi-80Gbps, futhi isebenzisa indlela entsha yokufaka ikhodi, i-128/132b, ekhulisa ukusebenza kahle kube yi-97%. I-bandwidth yangempela esebenzisekayo ifinyelela ku-77.4Gbps, elingana nokuphindwe kathathu kwe-DP 1.3/1.4, futhi idlula kude i-bandwidth yethiyori ye-HDMI 2.1 ye-48Gbps.
Ngenxa yalokho, i-DP 2.0 ingasekela kalula i-8K/60Hz HDR, >8K/60Hz SDR, 4K/144Hz HDR, 2×5K/60Hz kanye nezinye izinhlobo zokukhipha. Ayigcini nje ngokusekela noma yisiphi isibonisi se-8K ngaphandle kokucindezelwa, kodwa futhi ingasekela ukujula kombala we-30-bit (imibala engaphezu kwezigidigidi). Sebenzisa i-8K HDR.
I-DisplayPort 2.0: I-Thunderbolt 3, i-UHBR, kanye nekhebula ledatha elingasebenzi
Ngokuphathelene nemigqa yedatha, i-DP 2.0 empeleni yethula izindlela ezintathu ezihlukene, lapho i-bandwidth yesiteshi ngasinye isethwe ku-10Gbps, 13.5Gbps kanye no-20Gbps ngokulandelana. I-VESA iyibiza ngokuthi “i-UHBR/Ultra High Bit Rate”. Ngokusho kwe-bandwidth ngokulandelana ebizwa ngokuthi i-UHBR 10, i-UHBR 13.5, ne-UHBR 20.
I-bandwidth yokuqala ye-UHBR 10 ingu-40Gbps, kanti i-bandwidth esebenzayo ingu-38.69Gbps. Intambo yethusi engasebenzi ingasetshenziswa. Iphrojekthi yesitifiketi sentambo ye-DP 8K yangaphambilini empeleni iyifaka, okungukuthi, intambo yedatha ye-DP edlula isitifiketi se-8K ihlangabezana nezidingo zobuqotho besignali ze-UHBR 10.
I-UHBR 13.5 kanye ne-UHBR 20 zihlukile. Ama-bandwidth okuqala angama-54Gbps kanye nama-80Gbps, kanti ama-bandwidth asebenzayo angama-52.22Gbps kanye nama-77.37Gbps. Izintambo ezingasebenzi zingasetshenziswa kuphela ekudlulisweni kwebanga elifushane kakhulu, njengokufaka i-notebook docking.
