Nhanganyaya kuDisplayPort, HDMI uye Type-C Interfaces
Musi wa29 Mbudzi, 2017, HDMI Forum, Inc. yakazivisa kuburitswa kweHDMI 2.1, 48Gbps HDMI, uye 8K HDMI specifications, zvichiita kuti zviwanikwe kune vese vanoshandisa HDMI 2.0. Standard itsva iyi inotsigira 10K resolution @ 120Hz (10K HDMI, 144Hz HDMI), nebandwidth yakawedzerwa kusvika ku48Gbps, uye inounzira dynamic HDR uye variable refresh rate (VRR) technologies.
Musi wa26 Chikunguru, 2017, mubatanidzwa weUSB 3.0 Promoter Group, unosanganisira makambani etekinoroji akadai seApple, HP, Intel, neMicrosoft, wakazivisa USB 3.2 standard (USB 3.1 C TO C, USB C 10Gbps, Type C Male TO Male), iyo inotsigira kutapurirana kwe20Gbps muzvikamu zviviri uye inokurudzira Type-C senzira yakabatana.
Musi wa3 Kurume, 2016, VESA (Video Electronics Standards Association) yakaburitsa zviri pamutemo vhezheni itsva yemuenzaniso wekutumira ma audio-visual, DisplayPort 1.4. Iyi vhezheni inotsigira 8K@60Hz uye 4K@120Hz, uye kekutanga inobatanidza tekinoroji yekudzvanya display stream (DSC 1.2).

Kuburitswa kwepamutemo kwemitemo yakagadziriswa kunotarisirwa
Dhijitari yeDisplayPort 1.4 yaburitswa zviri pamutemo! Inotsigira vhidhiyo ye60Hz 8K
Musi wa1 Kurume, VESA (Video Electronics Standards Association) yakazivisa zviri pamutemo vhezheni itsva yeDisplayPort 1.4 inotumira mashoko nekuona. Iyi vhezheni itsva inowedzera kugona kutumira mavhidhiyo nedata kuburikidza neType-C (USB C 10Gbps, 5A 100W USB C Cable), uku ichitsigira HDR metadata transmission uye extended audio specifications. Iyi vhezheni itsva inoonekwa seyekutanga kugadziriswa kukuru mushure mekuburitswa kweDisplayPort 1.3 munaGunyana 2014.
Panguva imwe chete, iyi ndiyo zvakare DP standard yekutanga inotsigira tekinoroji yeDSC 1.2 (Display Stream Compression). MuDSC 1.2 vhezheni, kudzvanywa kwevhidhiyo isina kurasikirwa kwe3:1 kunogona kubvumidzwa.
"Alternate Mode (Alt Mode)" inopihwa neDP 1.3 standard inototsigira kutapurirana kwemavhidhiyo nedata panguva imwe chete kuburikidza neUSB Type-C neThunderbolt interfaces. Kunyange hazvo DP 1.4 ichitora danho rinotevera, zvichibvumira kutapurirana kwevhidhiyo yepamusoro panguva imwe chete ukuwo SuperUSB (USB 3.0) ichishandiswa kutapurirana data.
Pamusoro pezvo, DP 1.4 ichatsigira vhidhiyo ye60Hz 8K resolution (7680 x 4320) HDR pamwe nevhidhiyo ye120Hz 4K HDR.
Zvimwe zvigadziriso zveDP 1.4 ndeizvi:
1. Kugadzirisa Zvikanganiso Pamberi (FEC): Chikamu chetekinoroji yeDSC 1.2, inotarisa kushivirira kwakakodzera kwekukanganisa pakudzvanya vhidhiyo kuti ibudiswe kune zviratidziro zvekunze.
2. Kutumirwa kweHDR Metadata: Nekushandisa "secondary data packet" muDP standard, inopa rutsigiro rweCTA 861.3 standard iripo, iyo inobatsira zvikuru kune DP-HDMI 2.0a conversion protocol. Pamusoro pezvo, inopa kutapurirana kwemetadata packet kunochinjika, ichitsigira dynamic HDR yeramangwana.
3. Kutumirwa Kwenzwi Rakawedzerwa: Izvi zvinogona kusanganisira zvinhu zvakaita se32-bit audio channels, 1536kHz sampling rate, uye mafomati ese enzwi anozivikanwa parizvino.
VESA inoti DP 1.4 ichave ndiyo nzira yakanakisisa yekusangana nezvinodiwa zvekutumira manzwi nemavhidhiyo zvemhando yepamusoro zvemidziyo yemagetsi yepamusoro.
Chinangwa chekuzvarwa kweDisplayport chaive chakajeka - kubvisa HDMI. Saka, kana ichienzaniswa neHDMI, haina chitupa cheinterface kana muripo wekodzero dzekodzero, uye yakaunganidza makambani makuru akawanda muindasitiri yekuratidzira kuti vagadzire sangano reVISA kuti vakwikwidzane nesangano reHDMI. Rondedzero iyi inosanganisira vagadziri vemachipisi epamusoro-soro nevagadziri vemidziyo yemagetsi, vakaita seIntel, NVIDIA, AMD, Apple, Lenovo, HP, nezvimwewo. Saka, zvinogona kuonekwa kuti Displayport yakakura sei. Mhedzisiro yekupedzisira yemutambo inozivikanwa nemunhu wese! Kune Displayport interface, nekuda kwekufamba kweHDMI interface, mhedzisiro yekuparadzira yeDisplayport interface muminda yakawanda haina kunge yakanaka. Zvisinei, mweya wekufambira mberi unoenderera mberi weDisplayport interface unoyeuchidzawo HDMI kuti irambe ichikura. Mutambo pakati pezviviri ucharamba uripo mune ramangwana.
Musi wa28 Mbudzi, mukuru weHDMI Forum akazivisa kuburitswa kwepamutemo kwemhando yehunyanzvi yeHDMI 2.1 yazvino.
Zvichienzaniswa nekare, shanduko huru ndeyekuwedzera kukuru kwebandwidth, iyo ikozvino inogona kutsigira mavhidhiyo e10K padanho repamusoro. Kureba kwebandwidth yeHDMI 2.0b parizvino i18 Gbps, nepo HDMI 2.1 ichawedzera kusvika ku48 Gbps, iyo inogona kutsigira zvizere mavhidhiyo asina kurasikirwa ane resolutions uye refresh rates dzakadai se4K/120Hz, 8K/60Hz, uye 10K, uye inotsigirawo dynamic HDR. Nekuda kweizvi, standard itsva yatora tambo itsva yedata inokurumidza zvikuru (Ultra High Speed HDMI Cable).
