Gawo ili likufotokoza chingwe cha DisplayPort

Zingwe za DisplayPort
Ndi muyezo wapamwamba kwambiri wowonetsera digito womwe ungalumikizidwe ndi makompyuta ndi ma monitor, komanso makompyuta ndi zisudzo zapakhomo. Ponena za magwiridwe antchito, DisplayPort 2.0 imathandizira bandwidth yayikulu yotumizira ma data ya 80Gb/S. Kuyambira pa June 26, 2019, bungwe lokhazikika la VESA lalengeza mwalamulo za muyezo watsopano wotumizira ma data wa DisplayPort 2.0, womwe umagwirizanitsidwa kwambiri ndi Thunder 3 ndi USB-C. Ikhoza kukwaniritsa zosowa za 8K ndi zotulutsa zapamwamba zowonetsera. Ndi kusintha koyamba kwakukulu kuyambira protocol ya DisplayPort 1.4.
Zisanachitike zimenezo, bandwidth yonse ya DP 1.1, 1.2 ndi 1.3/1.4 inali 10.8Gbps, 21.6Gbps ndi 32.4Gbps motsatana, koma liwiro logwira ntchito linali 80% yokha (8/10b code), zomwe zinali zovuta kukwaniritsa zofunikira za 6K ndi 8K high resolution, high color depth komanso high refresh rate.
DP 2.0 imawonjezera bandwidth ya theoretical kufika pa 80Gbps, ndipo imagwiritsa ntchito njira yatsopano yolembera, 128/132b, yomwe imawonjezera mphamvu kufika pa 97%. Bandwidth yeniyeni yogwiritsidwa ntchito ndi 77.4Gbps, yofanana ndi katatu kuposa DP 1.3/1.4, ndipo imaposa kwambiri bandwidth ya theoretical ya HDMI 2.1 ya 48Gbps.
Zotsatira zake, DP 2.0 imatha kuthandizira mosavuta 8K/60Hz HDR, >8K/60Hz SDR, 4K/144Hz HDR, 2×5K/60Hz ndi mitundu ina yotulutsa. Sikuti imangothandizira chowunikira chilichonse cha 8K popanda kukanikiza, komanso imatha kuthandizira kuzama kwa utoto wa 30-bit (mitundu yoposa biliyoni imodzi). Ikani 8K HDR.


DisplayPort 2.0: Thunderbolt 3, UHBR, ndi chingwe cha data chopanda ntchito
Ponena za mizere ya deta, DP 2.0 imayambitsa njira zitatu zosiyana, ndipo bandwidth iliyonse ya channel imayikidwa pa 10Gbps, 13.5Gbps ndi 20Gbps motsatana. VESA imatcha "UHBR/Ultra High Bit Rate". Malinga ndi bandwidth motsatana imatchedwa UHBR 10, UHBR 13.5, UHBR 20.
Bandwidth yoyambirira ya UHBR 10 ndi 40Gbps, ndipo bandwidth yogwira ntchito ndi 38.69Gbps. Waya wamkuwa wopanda ntchito ungagwiritsidwe ntchito. Pulojekiti yapitayi ya DP 8K wire certification ikuphatikizapo, ndiko kuti, waya wa data wa DP womwe umadutsa certification ya 8K ukukwaniritsa zofunikira za UHBR 10.
UHBR 13.5 ndi UHBR 20 ndi zosiyana. Ma bandwidth oyambirira ndi 54Gbps ndi 80Gbps, ndipo ma bandwidth ogwira ntchito ndi 52.22Gbps ndi 77.37Gbps. Mawaya osagwiritsidwa ntchito amatha kugwiritsidwa ntchito pokhapokha ngati pali ma transmission akutali kwambiri, monga kuyika ma notepad pa laputopu.
