Lithapo tsa DisplayPort
Ke maemo a holimo a hlalosang a dijithale a sebopeho sa sebopeho se ka hokelang likhomphutha le limonita, hammoho le likhomphutha le libaesekopo tsa lapeng. Mabapi le ts'ebetso, DisplayPort 2.0 e ts'ehetsa lebelo le phahameng la phetisetso ea 80Gb/S. Ho tloha ka la 26 Phuptjane 2019, mokhatlo o tloaelehileng oa VESA o phatlalalitse ka molao mokhoa o mocha oa phetiso ea data oa DisplayPort 2.0, o kopantsoeng haufi le Thunder 3 le USB-C. E ka fihlela litlhoko tsa 8K le tlhahiso ea boemo bo holimo. Ke ntjhafatso ea pele e kholo ho tloha ho protocol ea DisplayPort 1.4.
Pele ho moo, kakaretso ea bandwidth ea DP 1.1, 1.2 le 1.3 / 1.4 e ne e le 10.8Gbps, 21.6Gbps le 32.4Gbps ka ho latellana, empa tekanyo e sebetsang e ne e le 80% feela (khoutu ea 8 / 10b), e neng e le thata ho finyella litlhoko tsa 6K le 8K resolution e phahameng, botebo ba mebala e phahameng le sekhahla se phahameng sa ho khatholla.
DP 2.0 e eketsa bandwidth ea theory ho 80Gbps, 'me e sebelisa mochine o mocha oa encoding, 128 / 132b, o eketsang katleho ho 97%. Bophahamo ba sebele bo ka sebelisoang bo fihla ho 77.4Gbps, e lekanang le makhetlo a mararo ho DP 1.3 / 1.4, 'me e feta hole bandwidth ea theory ea HDMI 2.1 ea 48Gbps.
Ka lebaka leo, DP 2.0 e ka tšehetsa 8K/60Hz HDR habonolo,> 8K/60Hz SDR, 4K/144Hz HDR, 2×5K/60Hz le mefuta e meng ea tlhahiso. Ha se feela hore e ka ts'ehetsa leihlo leha e le lefe la 8K ntle le khatello, empa e ka ts'ehetsa botebo ba mebala ea 30-bit (mebala e fetang bilione). Kenya ts'ebetsong 8K HDR.
DisplayPort 2.0: Thunderbolt 3, UHBR, le thapo ea data e sa sebetseng
Mabapi le melaetsa ea data, DP 2.0 e hlile e hlahisa mekhoa e meraro e fapaneng, e nang le mocha o mong le o mong oa bandwidth o behiloeng ho 10Gbps, 13.5Gbps le 20Gbps ka ho latellana. VESA e e bitsa "UHBR/Ultra High Bit Rate". Ho latela bandwidth e bitsoang UHBR 10, UHBR 13.5, UHBR 20.
Bophahamo ba mantlha ba UHBR 10 ke 40Gbps, mme bandwidth e sebetsang ke 38.69Gbps. Ho ka sebelisoa terata ea koporo e sa sebetseng. Morero o fetileng oa setifikeiti sa terata oa DP 8K o hlile o o kenyelletsa, ke hore, mohala oa data oa DP o fetisang setifikeiti sa 8K o kopana le litlhoko tsa ponts'o ea matšoao a UHBR 10.
UHBR 13.5 le UHBR 20 li fapane. Li-bandwidth tsa pele ke 54Gbps le 80Gbps, 'me li-bandwidth tse sebetsang ke 52.22Gbps le 77.37Gbps. Lithapo tse sa sebetseng li ka sebelisoa feela bakeng sa phetisetso ea sebaka se sekhuts'oane haholo, joalo ka ho emisa lintlha.
