Yav Tom Ntej Generator Video Connector rau Koj Tus Kheej Tus Kheej
Tau ntau xyoo, lub computer kev lag luam tau pom ntau tus duab sib thooj sib txawv. Tus qauv VGA tau pab coj kev daws teeb meem thiab xim tawm ntawm tus thawj TV video connectors. DVI qhia peb txog cov lus qhia uas tso cai rau ntau xim thiab meej meej. Thaum kawg, qhov HDMI interface siv cov yeeb yaj kiab digital thiab cov suab paj nruag rau hauv ib txoj kab rau kev siv twj paj nruag hauv tsev thiab txawm tias cov lus qhia hauv PC. Yog li, nrog tag nrho cov kev nce qib no, vim li cas thiaj muaj lub DisplayPort connector? Qhov no yog qhov tseeb hauv tsab xov xwm no kom piav qhia.
Cov kev txwv ntawm cov yees duab txuas ntxiv
Ib qho ntawm peb qhov video loj tshaj plaws muaj teeb meem uas txwv tsis pub lawv siv nrog rau yav tom ntej hauv computer. Txawm tias lawv tau teeb meem txog qee qhov teeb meem, qee cov tseem nyob. Cia li saib txhua yam ntawm cov qauv thiab cov teeb meem uas lawv muaj:
DVI
- Tib DVI tag rau 1920x1200 daws teeb meem nrog 24-ntsis xim
- Dual-link DVI tag rau 2560 x 1600 daws teeb meem nrog 24-ntsis xim
- Hnyav cabling yuav tsum tau txuas rau screwed rau hauv daim npav / zaub
- Tsis muaj kev txhawb nqa
HDMI
- Version 2.0 txhawb txog li 4K kev txiav txim zoo tab sis haum tsis tseem
- Version 1.3 txhawb nqa txog 2560x1600 kev daws teeb meem nrog audio stream
- Version 1.1 txhawb nqa mus txog 1920 x 1200 daws teeb meem nrog audio stream
- Qeb 1 cables txwv 5 meters ntev
DisplayPort Qhia
DisplayPort tau tsim los ntawm cov tswvcuab ntawm Video Electronics Standards Association. Qhov no yog ib pawg uas muaj ze ntawm 170 lub tuam txhab uas tsim thiab txiav txim siab cov qauv siv nrog rau kev siv computer. Qhov no tsis yog cov pab pawg uas tau tsim cov qauv txheej txheem HDMI. Vim tias qhov xav tau ntau dua ntawm cov computers thiab IT kev lag luam, pawg VESA tsim tau DisplayPort.
Raws li lub cev cabling, DisplayPort cables thiab connectors zoo nkaus li cov kab mob USB lossis HDMI uas niaj hnub siv rau hauv feem ntau cov computers. Cov connectors me ua kom yooj yim cabling ntawm lub system thiab cia cov connector mus rau muab tso rau hauv dav ntau yam khoom. Ntau cov phau ntawv sau xov tooj tsis tuaj yeem ua kom haum tus VGA los yog DVI connector tam sim no, tab sis DisplayPort's profile yuav tso cai rau nws. Ib yam li ntawd, tus tsim qauv nqes pub mus txog plaub lub rooj txuas mus rau ib qho PCI bracket hauv ib lub PC duab.
Cov kev siv tam sim no siv los ntawm DisplayPort connectors kuj tso cai rau ntau dua ntawm cov ntaub ntawv bandwidth thoob lub cable. Qhov no tso cai rau nws nthuav dav tshaj 2560x1600 kev daws teeb meem ntawm dual-txuas DVI thiab HDMI v1.3 connectors. Qhov no tsis yog ib qho teeb meem rau cov uas twb muaj lawm, tab sis nws yog qhov tseem ceeb rau kev loj hlob yav tom ntej ntawm 4K los yog UltraHD Display uas yuav tsum muaj plaub zaug ntawm cov ntaub ntawv bandwidth ntawm cov yees duab 1080p thiab lub caij nyoog txav mus rau 8K yees duab. Ntxiv rau qhov video stream, cabling kuj tuaj yeem pab txhawb lub 8-channel uncompressed audio stream zoo li cov HDMI connector.
Ib qho ntawm qhov kev nce qib loj tshaj nrog lub DisplayPort system tab sis yog lub koom haum pabcuam. Qhov no yog ib qho ntxiv rau cov kab yees duab hauv kab uas yuav nqa tau yees duab ntxiv los yog cov ntaub ntawv ntxiv rau cov ntawv thov dua ntxiv. Ib qho piv txwv ntawm qhov no yog qhov kev txuas ntawm lub webcam los yog USB chaw nres nkoj uas tau ua rau hauv lub tshuab computer tsis tas yuav tsum tau ntxiv cabling. Ib co versions ntawm HDMI tau ntxiv Ethernet rau lawv, tiam sis qhov kev siv yuav tsis tshua muaj.
Ib qho uas ntau tus neeg yuav tsum tau paub txog yog tias ThunderBolt connectors yog qhov tseem ceeb hauv DisplayPort tus qauv nrog nthuav cov channel nta. Qhov no tsis muaj tseeb ntawm tag nrho cov versions tab sis ThunderBolt 3 yog ua raws li lub USB 3.1 connectors thiab cov qauv uas ua rau tej yam tseem ceeb tshaj plaws. Yog li, yog tias koj lub PC muaj ThunderBolt nco ntsoov xyuas cov ntawv kom paub tseeb tias nws tau tshaj koj cov zaub.
DisplayPort Ntau Tshaj Lawm
Ib qho tseem ceeb ua ntej nrog tus qauv DisplayPort yog tias nws tsiv tshaj li qhov sib txuas thiab kab ntawm lub PC thiab cov duab. Cov cuab yeej siv kuj siv tau rau hauv cov lus qhia ntawm lub tshuab los sis cov ntawv sau kom txo tau cov naj npawb ntawm cov khoom sib txuas thiab cov hlua. Qhov no yog vim ntawm DisplayPort qauv nrog rau ib txoj kev rau kev sib txuas ncaj qha.
Qhov no txhais li cas yog tias cov ntaub ntawv yuav tshem tawm ntau cov khoom hluav taws xob uas yuav tsum tau hloov cov video teeb liab los ntawm daim video rau hauv ib qho uas siv tau tsav tsav lub cev. Xwb, lub LCD vaj huam sib luag siv lub DisplayPort tsav uas ua rau cov khoom siv hluav taws xob no. Yeej tseem ceeb, lub teeb liab uas los ntawm daim npav video ncaj qha los ntawm lub xeev lub cev ntawm lub pixels ntawm cov lus. Qhov no yuav tso cai rau me me nrog cov khoom siv hluav taws xob tsawg dua. Qhov no yuav ua rau muaj kev cia siab txog cov nqi ntawm cov kev qhia kom poob.
Nrog cov nta, nws tau vam tias DisplayPort muab kev ua haujlwm rau ntau yam khoom uas tsis yog lub computer, cov PCs, thiab cov phau ntawv sau. Cov neeg siv khoom me me kuj tseem muab cov duab DisplayPort txuas rau kev siv nrog cov tshaj tawm.
Tseem Rov Qab Compatible
Txawm hais tias DisplayPort cov qauv tam sim no tsis muaj cov lus tshaj tawm sab nraud ntawm lub cev thiab cov khoom sib txuas, tus qauv yuav hu rau kev txhawb nqa cov qauv kev cai qub nrog VGA, DVI thiab HDMI. Tag nrho cov ntawm no yuav tsum tau ua raws li kev sib txuas nrog lwm tus neeg siv. Nws yuav tsis yooj yim dua cov kab DVI-los-VGA style adaptor, tab sis tseem muaj nyob rau hauv ib lub xov tooj me me.
