Cov xov hlau DisplayPort
Yog tus qauv digital display interface uas muaj kev txhais siab uas tuaj yeem txuas nrog cov khoos phis tawj thiab cov saib xyuas, nrog rau cov khoos phis tawj thiab cov chaw ua yeeb yaj kiab hauv tsev. Hais txog kev ua tau zoo, DisplayPort 2.0 txhawb nqa qhov siab tshaj plaws ntawm 80Gb / S. Txij li thaum Lub Rau Hli 26, 2019, VESA tus qauv lub koom haum tau tshaj tawm cov lus qhia tshiab ntawm DisplayPort 2.0 cov ntaub ntawv xa mus, uas tau sib xyaw nrog Thunder 3 thiab USB-C. Nws tuaj yeem ua tau raws li qhov xav tau ntawm 8K thiab cov zis tso zis siab dua. Yog thawj qhov hloov tshiab loj txij li DisplayPort 1.4 protocol.
Ua ntej ntawd, qhov theoretical tag nrho bandwidth ntawm DP 1.1, 1.2 thiab 1.3/1.4 yog 10.8Gbps, 21.6Gbps thiab 32.4Gbps feem, tab sis tus nqi ua haujlwm tau zoo tsuas yog 80% (8/10b code), uas nyuaj rau ua kom tau raws li qhov yuav tsum tau ua ntawm 6K thiab 8K kev daws teeb meem siab, qhov tob xim siab thiab qhov siab refresh.
DP 2.0 ua rau qhov theoretical bandwidth nce mus txog 80Gbps, thiab siv lub tshuab encoding tshiab, 128/132b, uas ua rau qhov ua tau zoo nce mus txog 97%. Qhov bandwidth siv tau tiag tiag yog txog li 77.4Gbps, sib npaug rau peb zaug ntawm DP 1.3/1.4, thiab ntau dua qhov theoretical bandwidth ntawm HDMI 2.1 ntawm 48Gbps.
Yog li ntawd, DP 2.0 tuaj yeem yooj yim txhawb nqa 8K / 60Hz HDR, >8K / 60Hz SDR, 4K / 144Hz HDR, 2 × 5K / 60Hz thiab lwm yam hom ntawv tso zis. Nws tsis tsuas yog tuaj yeem txhawb nqa txhua lub monitor 8K yam tsis muaj kev sib txuas, tab sis nws kuj tseem tuaj yeem txhawb nqa 30-ntsis xim tob (ntau dua ib billion xim). Siv 8K HDR.
DisplayPort 2.0: Thunderbolt 3, UHBR, thiab passive data cable
Hais txog cov kab ntaub ntawv, DP 2.0 yeej qhia txog peb txoj kev sib txawv, nrog txhua qhov channel bandwidth teeb tsa ntawm 10Gbps, 13.5Gbps thiab 20Gbps feem. VESA hu nws ua "UHBR/Ultra High Bit Rate". Raws li bandwidth feem hu ua UHBR 10, UHBR 13.5, UHBR 20.
Tus bandwidth thawj zaug ntawm UHBR 10 yog 40Gbps, thiab qhov bandwidth ua haujlwm tau zoo yog 38.69Gbps. Cov hlau tooj liab passive siv tau. Qhov project DP 8K hlau pov thawj yav dhau los suav nrog nws, uas yog, cov hlau ntaub ntawv DP uas dhau daim ntawv pov thawj 8K ua tau raws li cov kev cai ntawm UHBR 10.
UHBR 13.5 thiab UHBR 20 txawv. Cov bandwidths thawj yog 54Gbps thiab 80Gbps, thiab cov bandwidths zoo yog 52.22Gbps thiab 77.37Gbps. Cov xov hlau passive tsuas yog siv tau rau kev xa xov luv luv xwb, xws li notebook docking.
