Qhov no muaj xws li 7.1 suab hauv HDMI version 1.4 thiab tam sim no mus txog tag nrho 32 suab raws nrog qhov tseeb HDMI version 2.0.
Ntxiv Xim qhov tob
Analog thiab cov xim rau cov PC computers tau ntev tau txwv kom muaj 24-ntsis xim uas ua tau roughly 16.7 lab xim. Qhov no feem ntau xam tias yog qhov tseeb vim hais tias tib neeg qhov muag tsis paub qhov txawv ntawm qhov ntxoov ntxoo yooj yim. Nrog rau kev nce siab ntawm HDTV , tib neeg lub qhov muag yuav qhia tau qhov txawv ntawm txhua yam xim ntawm 24-ntsis xim qhov tob thiab ntau dua, txawm tias nws tsis paub qhov txawv xim.
DVI tsuas yog siv rau qhov 24-ntsis xim qhov tob . Thaum ntxov HDMI versions kuj tas rau no 24-ntsis xim, tab sis nrog version 1.3 xim qhov tob ntawm 30, 36 thiab txawm 48-ntsis tau ntxiv. Qhov no zoo heev rau qhov zoo tshaj plaws ntawm cov xim uas tuaj yeem pom tau tso tawm, tab sis ob qho tib si graphics adapter thiab saib yuav tsum txhawb qhov HDMI version 1.3 los yog siab dua. Hauv kev sib piv, DisplayPort tseem tau nthuav cov xim xim txhawb txog 48-ntsis xim qhov tob.
Rov qab Compatible
Ib qho ntawm cov tseem ceeb tshaj plaws uas muaj nrog HDMI tus qauv yog qhov peev xwm rau nws siv nrog DVI connectors. Los ntawm kev siv ntawm ib lub cable adapter, ib qho HDMI ntsaws tuaj yeem txuas mus rau DVI qhov chaw nres nkoj rau qhov teeb liab video. Qhov no yog qhov zoo tshaj plaws rau cov neeg uas ua haujlwm nrog lub HDMI video tso tawm tiam sis lawv lub TV los yog lub computer monitor tsuas muaj DVI cov lus qhia. Nws yuav tsum raug sau tseg tias qhov no tsuas yog siv qhov video feem ntawm HDMI kab ke kom tsis muaj suab nrog nws. Tsis tas li ntawd, thaum saib xyuas nrog DVI connector txuas tau rau qhov chaw nres nkoj HDMI duab hauv tshuab computer, HDMI saib tsis tuaj yeem txuas mus rau DVI qhov chaw nres nkoj ntawm lub computer.
DisplayPort tsis muaj txhij ntau hauv cheeb tsam no. Yuav kom siv DisplayPort nrog lwm cov video connectors, ib qho kev sib txuas lub dongle yuav tsum hloov cov video teeb liab los ntawm Displayport tus qauv mus rau HDMI, DVI lossis VGA. Cov connectors no yuav kim heev thiab yog ib qhov teeb meem loj rau DisplayPort connector.
Version 2.0 Ntxiv
Nrog rau qhov siab ntawm UltraHD los yog 4K Qhia , muaj qee qhov kev xav tau ntawm cov kev siv bandwidth thiaj li yuav tau nqa tag nrho cov ntaub ntawv tsim nyog rau xws li qhov kev daws teeb meem. Cov txheej txheem HDMI version 1.4 tau nce mus txog 2160p cov lus samfwm uas yuav tsum tau muaj, tabsis tsuas yog 30 ntais ntawm ib ntus. Qhov no yog qhov tseem ceeb tshaj rau cov qauv DisplayPort. Ua tsaug, HDMI ua hauj lwm pab pawg version tso tawm version 2.0 ua ntej lub siab ntawm 4K cov lus qhia txog kev ua lag luam. Ntxiv rau cov ncej siab ntawm UltraHD cov tshooj cai, nws kuj txhawb:
- Muaj peev xwm muaj ob (1080p) video ntws nqa dua ib zaug xwb.
- Paub cov suab sampling rau kev paub lub suab lus ncaj ncees.
- Muaj peev xwm nqa plaub suab ntws mus rau ntau tus neeg siv ntawm ib kab txuas.
- Kev them nyiaj yug rau 21: 9 piv piv yees duab rau cov kab lus dav dav.
- Dynamic suab rau video synchronization.
- Kev them nyiaj yug rau kev hais kom ua thiab tswj kev siv phom ntau yam rau kev tswj cov cuab yeej siv los ntawm ib qho khoom siv.
Feem ntau ntawm cov qauv no tseem tsis tau muab kev sib txuas rau hauv tsev neeg siv hluav taws xob lossis lub tshuab computer tiam sis lawv muaj peev xwm ua rau cov neeg siv uas yuav tsum tau sib koom siv lub tshuab computer, cov duab lossis lub teeb teeb.
Puas Yog Koj Saib HDMI hauv Computer System?
Txij ntawm no tus taw tes, txhua tus neeg siv lub laptop thiab cov computers yuav tsum tuaj nrog qhov chaw nres nkoj hauv HDMI. Qhov no ua rau nws yooj yim mus siv lawv nrog koj tus qauv digital computer monitors thiab HDTVs. Nws yuav tsum raug sau tseg tias tseem tshuav ob peb chav kawm ntawv hauv chav kawm ntawm lub lag luam uas tsis muaj qhov txuas nrog no. Kuv xav ntshe zam cov computers no vim nws yog ib qho kev lav nyob rau hauv lub neej yav tom ntej. Ntxiv nrog rau qhov no, qee cov chav kawm hauv chav kawm cov computers yuav tsis muaj qhov chaw nres tsheb hauv HDMI tab sis txhais tau tias, tuaj nrog DisplayPort. Qhov no yog lwm txoj kev tsim nyog, tiam sis koj xav tau kom koj muaj ib qho saib xyuas uas yuav pab txhawb qhov kev sib txuas lus.
Qhov teeb meem nrog HDMI yug ntau dua rau ntsiav tshuaj computers thiab smartphones. Qhov no tsis yog ib yam uas yog tus qauv rau lawv, tiam sis koj xav tau kev pab txhawb rau lub micro lossis Mini-HDMI connector kom nws tuaj yeem hooked mus rau ib qho HDTV rau kev ua yeeb yaj kiab los yog cov yees duab ntawm cov yeeb yaj kiab.
