HDMI 2.1 controversy DP 2.0 zaj lus qhia: Cables yuav tsum tau ntawv pov thawj.

Nco ntsoov qhov kev sib cav tsis ntev los no dhau ntawm HDMI 2.1 tus qauv?HDMI 2.1 yog qhov tseeb lossis tsis tseeb vim qhov ua tsis tiav ntawm HDMI cov tub ceev xwm, ua rau cov neeg siv khoom tsis meej pem.Hmoov zoo, VESA tau kawm nws zaj lus qhia lub sijhawm no thiab yuav tsum tau lees paub thiab sau npe DP 2.0 cables, kom cov nqi sib txawv ntawm cov cables tau yooj yim.Tus qauv DP 2.0 tau tshaj tawm rov qab rau xyoo 2019. Tus qauv tshiab nce qhov theoretical bandwidth mus rau 80Gbps thiab siv cov txheej txheem encoding tshiab, 128/132b, uas ua rau kom ua tau zoo rau 97%.

Qhov tseeb muaj txog li 77.4Gbps, sib npaug rau tag nrho peb zaug DP 1.3/1.4, deb tshaj qhov theoretical bandwidth ntawm HDMI 2.1 48Gbps.

Txawm li cas los xij, hais txog cov kab ntawv, DP 2.0 kuj muaj peb yam sib txawv.Qhov bandwidth ntawm txhua channel yog teem rau ntawm 10Gbps, 13.5Gbps thiab 20Gbps, uas VESA hu ua "UHBR / Ultra High Bit Rate".Lawv hu ua UHBR 10, UHBR 13.5 thiab UHBR 20 raws li qhov bandwidth.

Tus thawj bandwidth ntawm UHBR 10 yog 40Gbps, thiab qhov zoo bandwidth yog 38.69Gbps.Passive tooj liab hlau yog txaus.Yav dhau los DP 8K xaim ntawv pov thawj qhov project yeej suav nrog nws, uas yog, DP cov ntaub ntawv xaim uas tau dhau 8K ntawv pov thawj ua tau raws li cov teeb liab kev ntseeg siab ntawm UHBR 10.

UHBR 13.5, UHBR 20 yog qhov sib txawv, tus thawj bandwidth 54Gbps, 80Gbps, zoo bandwidth 52.22Gbps, 77.37Gbps, passive hlau tsuas yog siv tau rau kev sib kis luv luv, xws li lub laptop nthuav dav docking, ntev xav tau cov xaim txuas ntxiv, uas yog, cog cog nrog rau kev tswj hwm thiab amplification nti.

Vim tias tus qauv no, DP 2.0 cables yeej sib txawv, thiab VESA tam sim no tau txiav txim siab los lees paub cov cables sib txawv kom lawv tuaj yeem sib txawv.

Tshwj xeeb, DP 2.0 cables tuaj nyob rau hauv ob tus qauv nyob ntawm qhov ceev.DP40 cables txhawb UHBR10 tus qauv ntawm 10Gbps ib channel nyob rau hauv txhua ntawm plaub sab hauv, rau tag nrho cov ceev ntawm 40Gbps.

Cables sau npe DP80 yog UHR20 20Gbps ib channel nrog ceev txog 80Gbps.

DP40, DP80 cable yog li muaj qhov sib txawv meej, tsis yooj yim rau confuse, manufacturers xav ntses hauv dej teeb meem tsis tuaj yeem ua tau, qhov no yog qhov zoo tiag tiag.

VESA tau tshaj tawm tias DP40 thiab DP80 tus qauv DP kab thiab MINI DP kab tau pib tsim khoom, thiab thawj pawg ntawm cov khoom siv thiab lwm yam khoom siv kuj tau dhau daim ntawv pov thawj.
