Eriri DisplayPort
Ọ bụ ọkọlọtọ ngosipụta dijitalụ dị elu nke enwere ike ijikọ na kọmputa na ihe nlele, yana kọmputa na ụlọ ihe nkiri. N'ihe gbasara arụmọrụ, DisplayPort 2.0 na-akwado oke bandwit nnyefe nke 80Gb/S. Site na June 26, 2019, ụlọ ọrụ ọkọlọtọ VESA kwupụtara ọkwa ọkọlọtọ nnyefe data DisplayPort 2.0 ọhụrụ, nke jikọtara ya na Thunder 3 na USB-C nke ọma. Ọ nwere ike igbo mkpa nke 8K na mmepụta ngosipụta dị elu. Ọ bụ mmelite mbụ dị mkpa kemgbe usoro DisplayPort 1.4.
Tupu nke ahụ, mkpokọta bandwit nke DP 1.1, 1.2 na 1.3/1.4 bụ 10.8Gbps, 21.6Gbps na 32.4Gbps n'otu n'otu, mana ọnụego arụmọrụ dị irè bụ naanị 80% (koodu 8/10b), nke siri ike imezu ihe achọrọ nke mkpebi dị elu nke 6K na 8K, omimi agba dị elu na ọnụego ume ọhụrụ dị elu.
DP 2.0 na-eme ka bandwit echiche dịkwuo elu ruo 80Gbps, ma jiri usoro nhazi ọhụrụ, 128/132b, nke na-eme ka arụmọrụ dịkwuo elu ruo 97%. Bandwit a na-eji eme ihe ruru 77.4Gbps, nke hà nhata ugboro atọ nke DP 1.3/1.4, ma gafere bandwit echiche 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 usoro mmepụta ndị ọzọ. Ọ bụghị naanị na ọ nwere ike ịkwado ihe nlele 8K ọ bụla na-enweghị mkpakọ, kamakwa ọ nwere ike ịkwado omimi agba 30-bit (ihe karịrị otu ijeri agba). Mee HDR 8K ngwa ngwa.
DisplayPort 2.0: Thunderbolt 3, UHBR, na eriri data na-anaghị arụ ọrụ
Maka usoro data, DP 2.0 na-ewebata usoro atọ dị iche iche, ebe ọ bụla ọwa bandwidth dị na 10Gbps, 13.5Gbps na 20Gbps n'otu n'otu. VESA kpọrọ ya "UHBR/Ultra High Bit Rate". Dịka ọ dị, a na-akpọ ya UHBR 10, UHBR 13.5, UHBR 20.
Oke ọsọ nke UHBR 10 bụ 40Gbps, oke ọsọ nke bandwit dị irè bụ 38.69Gbps. Enwere ike iji waya ọla kọpa na-anaghị arụ ọrụ. Ọrụ asambodo waya DP 8K gara aga gụnyere ya, ya bụ, waya data DP nke gafere asambodo 8K na-emezu ihe achọrọ maka iguzosi ike n'ezi ihe nke UHBR 10.
UHBR 13.5 na UHBR 20 dị iche. Bandwit mbụ bụ 54Gbps na 80Gbps, bandwit ndị dị irè bụkwa 52.22Gbps na 77.37Gbps. Enwere ike iji waya ndị na-anaghị agafe agafe naanị maka nnyefe dị mkpirikpi, dịka ebe a na-adọba akwụkwọ ndetu.
