Kev Taw Qhia Txog DisplayPort, HDMI thiab Type-C Interfaces
Thaum Lub Kaum Ib Hlis 29, 2017, HDMI Forum, Inc. tau tshaj tawm qhov kev tso tawm ntawm HDMI 2.1, 48Gbps HDMI, thiab 8K HDMI cov lus qhia, ua rau lawv muaj rau txhua tus neeg siv HDMI 2.0. Tus qauv tshiab txhawb nqa 10K kev daws teeb meem @ 120Hz (10K HDMI, 144Hz HDMI), nrog rau bandwidth nce mus txog 48Gbps, thiab qhia txog dynamic HDR thiab variable refresh rate (VRR) technologies.
Thaum Lub Xya Hli 26, 2017, USB 3.0 Promoter Group alliance, uas muaj cov tuam txhab thev naus laus zis xws li Apple, HP, Intel, thiab Microsoft, tau tshaj tawm tus qauv USB 3.2 (USB 3.1 C TO C, USB C 10Gbps, Hom C Txiv Neej TO Txiv Neej), uas txhawb nqa dual-channel 20Gbps kev sib kis thiab pom zoo Hom-C ua lub interface sib koom ua ke.
Thaum Lub Peb Hlis 3, 2016, VESA (Video Electronics Standards Association) tau tshaj tawm qhov version tshiab ntawm tus qauv xa suab-pom, DisplayPort 1.4. Qhov version no txhawb nqa 8K@60Hz thiab 4K@120Hz, thiab thawj zaug koom ua ke cov thev naus laus zis tso zis (DSC 1.2).

Xav kom muaj kev tso tawm cov qauv tshiab
Tus qauv DisplayPort 1.4 tau tso tawm lawm! Txhawb nqa 60Hz 8K video
Thaum Lub Peb Hlis 1, VESA (Video Electronics Standards Association) tau tshaj tawm qhov version tshiab ntawm tus qauv xa suab thiab duab DisplayPort 1.4. Tus qauv tshiab no ua kom muaj peev xwm xa video thiab cov ntaub ntawv los ntawm Type-C (USB C 10Gbps, 5A 100W USB C Cable), thaum txhawb nqa HDR metadata transmission thiab cov lus qhia txog suab ntev. Tus qauv tshiab no suav tias yog thawj qhov hloov tshiab loj tom qab tso tawm DisplayPort 1.3 thaum Lub Cuaj Hli 2014.
Tib lub sijhawm, qhov no kuj yog thawj tus qauv DP uas txhawb nqa DSC 1.2 (Display Stream Compression) thev naus laus zis. Hauv DSC 1.2 version, 3: 1 lossless video stream compression tuaj yeem tso cai.
Tus "Hom Lwm Hom (Alt Hom)" uas muab los ntawm tus qauv DP 1.3 twb txhawb nqa kev xa cov yeeb yaj kiab thiab cov ntaub ntawv tib lub sijhawm ntawm USB Type-C thiab Thunderbolt interfaces. Thaum DP 1.4 coj nws mus ib kauj ruam ntxiv, tso cai rau kev xa cov yeeb yaj kiab siab txhais tib lub sijhawm thaum SuperUSB (USB 3.0) siv rau kev xa cov ntaub ntawv.
Ntxiv rau, DP 1.4 yuav txhawb nqa 60Hz 8K kev daws teeb meem (7680 x 4320) HDR video nrog rau 120Hz 4K HDR video.
Lwm cov kev hloov tshiab ntawm DP 1.4 yog raws li nram no:
1. Kev Kho Qhov Yuam Kev Mus Tom Ntej (FEC): Ib feem ntawm DSC 1.2 thev naus laus zis, nws hais txog qhov kev zam txim kom raug thaum nias cov yeeb yaj kiab rau cov zis tawm mus rau cov zaub sab nraud.
2. Kev Xa Mus Rau HDR Metadata: Los ntawm kev siv "cov ntaub ntawv thib ob" hauv tus qauv DP, nws muab kev txhawb nqa rau tus qauv CTA 861.3 tam sim no, uas muaj txiaj ntsig zoo rau DP-HDMI 2.0a hloov pauv protocol. Tsis tas li ntawd, nws muab kev xa mus rau cov ntaub ntawv metadata yooj ywm dua, txhawb nqa HDR dynamic yav tom ntej.
3. Kev Sib Txuas Lus Suab Nthuav Dav: Cov lus qhia no tuaj yeem npog cov yam xws li 32-ntsis suab channel, 1536kHz sampling rate, thiab txhua hom suab paub tam sim no.
VESA hais tias DP 1.4 yuav dhau los ua tus qauv interface zoo tshaj plaws los ua kom tau raws li qhov xav tau ntawm kev xa suab thiab video zoo ntawm cov khoom siv hluav taws xob siab.
Lub hom phiaj ntawm kev yug los ntawm Displayport yog qhov tseeb - tshem tawm HDMI. Yog li ntawd, piv rau HDMI, nws tsis muaj daim ntawv pov thawj interface lossis cov nqi copyright, thiab tau sib sau ua ke ntau lub tuam txhab loj hauv kev lag luam zaub los tsim VISA koom haum los sib tw nrog HDMI koom haum. Daim ntawv teev npe suav nrog ntau lub tuam txhab tsim khoom siv high-end thiab cov chaw tsim khoom siv hluav taws xob, xws li Intel, NVIDIA, AMD, Apple, Lenovo, HP, thiab lwm yam. Yog li, nws tuaj yeem pom tias lub zog ntawm Displayport hnyav npaum li cas. Qhov kawg ntawm qhov kev ua si yog paub rau txhua tus! Rau Displayport interface, vim yog kev txav mus los ntawm HDMI interface, qhov cuam tshuam ntawm Displayport interface hauv ntau qhov chaw tsis tau zoo tagnrho. Txawm li cas los xij, kev nce qib tas mus li ntawm Displayport interface kuj ceeb toom HDMI kom txuas ntxiv txhim kho. Qhov kev ua si ntawm ob qho yuav txuas ntxiv mus rau yav tom ntej.
Thaum Lub Kaum Ib Hlis 28, tus thawj coj ntawm HDMI Forum tau tshaj tawm qhov kev tshaj tawm tshiab ntawm HDMI 2.1 tus qauv kev siv tshuab.
Piv nrog rau yav dhau los, qhov kev hloov pauv tseem ceeb tshaj plaws yog qhov nce ntxiv ntawm bandwidth, uas tam sim no tuaj yeem txhawb nqa 10K cov yeeb yaj kiab ntawm qib siab tshaj plaws. Qhov bandwidth tam sim no ntawm HDMI 2.0b yog 18 Gbps, thaum HDMI 2.1 yuav nce mus txog 48 Gbps, uas tuaj yeem txhawb nqa tag nrho cov yeeb yaj kiab tsis poob nrog kev daws teeb meem thiab cov nqi refresh xws li 4K / 120Hz, 8K / 60Hz, thiab 10K, thiab tseem txhawb nqa dynamic HDR. Vim li no, tus qauv tshiab tau txais yuav cov ntaub ntawv tshiab ultra-high-speed (Ultra High Speed HDMI Cable).
