Igwe eriri DisplayPort
Bụ ọkọlọtọ ngosi ihe ngosi dijitalụ dị elu nke enwere ike ijikọ na kọmpụta na ihe nleba anya, yana kọmputa na ihe nkiri ụlọ.N'ihe gbasara arụmọrụ, DisplayPort 2.0 na-akwado bandwit nnyefe kacha nke 80Gb/S.Site na June 26, 2019, ụlọ ọrụ ọkọlọtọ VESA kwupụtara ọkwa ọkwa nnyefe data DisplayPort 2.0 ọhụrụ, nke jikọtara ya na Thunder 3 na USB-C.Ọ nwere ike gboo mkpa nke 8K na mmepụta ngosi ọkwa dị elu.Bụ mmelite izizi izizi kemgbe Protocol DisplayPort 1.4.
Tupu nke ahụ, theoretical ngụkọta bandwit nke DP 1.1, 1.2 na 1.3 / 1.4 bụ 10.8Gbps, 21.6Gbps na 32.4Gbps karị, ma oru oma ọnụego bụ naanị 80% (8/10b code), nke siri ike izute chọrọ nke. 6K na 8K mkpebi dị elu, omimi agba dị elu na ọnụego ume ọhụrụ dị elu.
DP 2.0 na-abawanye bandwidth usoro ihe omume na 80Gbps, ma na-eji usoro ntinye koodu ọhụrụ, 128/132b, nke na-abawanye arụmọrụ na 97%.Bandwidwidi eji arụ ọrụ n'ezie ruru 77.4Gbps, ya na DP 1.3/1.4 ugboro atọ, ma karịa bandwidth usoro ihe omimi nke HDMI 2.1 nke 48Gbps.
N'ihi ya, DP 2.0 nwere ike ịkwado 8K / 60Hz HDR,> 8K / 60Hz SDR, 4K / 144Hz HDR, 2 × 5K / 60Hz na ụdị mmepụta ndị ọzọ.Ọ bụghị naanị na ọ nwere ike ịkwado nyocha 8K ọ bụla na-enweghị mkpakọ, mana ọ nwekwara ike ịkwado omimi agba 30-bit (ihe karịrị otu ijeri agba).Mejuputa 8K HDR.
DisplayPort 2.0: Thunderbolt 3, UHBR, na eriri data na-agafe agafe
N'ihe gbasara ahịrị data, DP 2.0 na-ewebata usoro atọ dị iche iche, yana bandwidth ọwa ọ bụla edobere na 10Gbps, 13.5Gbps na 20Gbps n'otu n'otu.VESA kpọrọ ya "UHBR/Ultra High Bit Rate".Dabere na bandwit akpọrọ UHBR 10, UHBR 13.5, UHBR 20.
bandwidth izizi nke UHBR 10 bụ 40Gbps, yana bandwidth dị irè bụ 38.69Gbps.Enwere ike iji waya ọla kọpa na-agafe agafe.Ọrụ asambodo waya DP 8K gara aga gụnyere ya, ya bụ, waya data DP nke na-agafe asambodo 8K na-emezu ihe nrịbama ziri ezi chọrọ nke UHBR 10.
UHBR 13.5 na UHBR 20 dị iche.Ihe bandwidth mbụ bụ 54Gbps na 80Gbps, yana bandwit dị irè bụ 52.22Gbps na 77.37Gbps.Enwere ike iji waya na-agafe agafe naanị maka nnyefe dị anya dị mkpụmkpụ, dị ka ntinye akwụkwọ ndetu.
