DVI vs VGA Difference: Onetsani Miyezo Poyerekeza
M'ndandanda wazopezekamo
- 1. Kodi DVI ndi chiyani?
- 2. VGA ndi chiyani?
- 3. Kusiyana kwakukulu pakati pa DVI ndi VGA
- 4. Ubwino ndi Kuipa kwake
- 5. Ndi liti Kugwiritsa Ntchito DVI kapena VGA?
- 6. Mapeto
Tekinoloje ikupitabe bwino, komanso mawonekedwe owonekera. Mayina akulu awiri, Digital Visual Interface (DVI) ndi Video Graphics Array (VGA), tsopano ndi kiyi yolumikizira zida. Kudziwa momwe DVI ndi VGA zimasiyanirana ndikofunikira pakuwoneka bwino komanso kuyanjana m'malo ambiri.
Zofunika Kwambiri
Kodi DVI ndi chiyani?
DVI imayimira Digital Visual Interface. Ndi njira yotumizira ma siginecha a digito kuti awonetse matanthauzidwe apamwamba. Zinatuluka kumapeto kwa zaka za m'ma 1990 kuti zilowe m'malo mwa VGA ndikupereka chithunzithunzi chabwinoko komanso chithandizo chazosankha zapamwamba.
Tanthauzo ndi Mbiri Yake
DVI ndi mawonekedwe a digito owonetsera. Imatumiza kanema wa digito wosakanizidwa kuchokera kugwero, ngati kompyuta, kupita kuwonetsero, ngati chowunikira. Idapangidwa mu 1999 ndi makampani monga Intel ndi Hitachi kuti akwaniritse kufunikira kowonetsera bwino digito.
Mitundu ya DVI Connectors
DVI-D (Ya digito): Amatumiza ma siginecha a digito okha, abwino mpaka 1920x1200 pa 60Hz.
DVI-I (Yophatikizidwa): Imagwira ntchito ndi ma digito ndi ma analogi, abwino pazowonetsera zakale za VGA.
DVI-A (Analogi): Amatumiza ma analogi okha, ofanana ndi VGA.
Zinthu zazikulu za DVI
| Mtundu wa DVI cholumikizira | Zizindikiro Zothandizira | Maximum Resolution |
| DVI-D | Za digito | 1920x1200 pa 60Hz |
| DVI-I | Digital ndi Analogi | 1920x1200 pa 60Hz |
| DVI-A | Analogi | 1920x1200 pa 60Hz |
VGA ndi chiyani?
VGA, kapena Video Graphics Array, ndi njira yowonetsera cholowa. Zinatenga gawo lalikulu m'mbiri yakufalitsa mavidiyo a analogi. Yopangidwa mu 1980s, VGA inali ukadaulo wochita upainiya womwe unathandizira kukhazikitsa maziko a machitidwe amakono owonetsera.
A. Tanthauzo ndi Kufunika Kwa Mbiri Yakale
VGA ndi mawonekedwe amakanema a analogi omwe amagwiritsidwa ntchito kwambiri pamakompyuta ndi zida zina zowonetsera kwazaka zambiri. Zinali gawo lofunikira pakusintha koyambirira kwa PC. VGA inathandiza ogwiritsa ntchito kulumikiza makompyuta awo kumitundu yosiyanasiyana yowonetsera, kuphatikizapo CRT (Cathode Ray Tube) monitors.
Mbiri yakale ya VGA yagona pakutha kwake kupereka njira yokhazikika yotumizira zidziwitso zowoneka. Zimenezi zinachititsa kuti anthu ambiri azitengera makompyuta awo.
B. VGA Signal Transmission: Analogi Only
VGA imagwiritsa ntchito njira yotumizira ma analogi. Izi zikutanthauza kuti zambiri zamakanema zimaperekedwa kudzera mumitundu yosiyanasiyana yamagetsi yamagetsi. Mosiyana ndi mawonekedwe aposachedwa kwambiri a digito, mawonekedwe a analogi a VGA atha kubweretsa zovuta za kukhulupirika ndi malire a mawonekedwe akagwiritsidwa ntchito ndi matekinoloje amakono owonetsera digito.
Ngakhale VGA idakwaniritsa cholinga chake munthawi ya oyang'anira CRT, yakhala yachikale kwambiri m'zaka zotumizira mavidiyo a digito ndi mawonedwe apamwamba kwambiri. Zina mwazolepheretsa zazikulu za VGA ndi izi:
Kusasinthika kwapang'onopang'ono ndi mawonekedwe azithunzi poyerekeza ndi miyezo ya digito
Kutengeka ndi kusokonezedwa kwa ma analogi ndi kuwonongeka kwa zingwe zazitali
Kupanda chithandizo chaziwonetsero zapamwamba, monga mitengo yotsitsimula kwambiri komanso mawonekedwe osinthika
Ngakhale ndi zaka, VGA ikadali ndi malo ake m'machitidwe ena olowa ndi ntchito. VGA ikhoza kukondedwa muzochitika zomwe:
1.Kugwirizana ndi zida zakale zowonetsera ndizofunikira
2.Kulumikizana kwamtengo wapatali ndikofunika kwambiri kuposa zinthu zapamwamba
3.Chiwonetsero chowonetsera ndi zofuna za khalidwe lachithunzi ndizochepa
Kusiyana Kwakukulu Pakati pa DVI ndi VGA
Ubwino ndi Kuipa kwake
| Zofunikira | ZIWIRI | VGA |
| Ubwino wa Signal | Wapamwamba | Zochepa |
| Kutalikirana | Utali | Wachidule |
| Mtengo wa Interface | Wapamwamba | Zochepa |
| Thandizo la Hardware | Zochepa | Kufalikira |
| Interface Versatility | Wapamwamba | Zochepa |
Ndi liti kugwiritsa ntchito DVI kapena VGA?
Mapeto
Kwa iwo omwe amafufuza zosankha zapamwamba za Hardware, Advantech Industrial PC ndi PC yophatikizidwa ndi mafakitale opanda fan mayankho ndi zosankha zabwino kwambiri pazofunikira zapamwamba. Komanso, ngati mukuyang'ana makonzedwe a rackmount, a mafakitale PC 4U zingagwirizane ndi zosowa zanu.
Kwa opanga padziko lonse lapansi, mafakitale PC China imapereka mayankho atsatanetsatane amakampani opanga makompyuta. Kuphatikiza apo, the Advantech rackmount PC mndandanda amapereka durability ndi kudalirika kwa chilengedwe wovuta.
Ngati cholinga chanu chiri pakuphunzira pamakina kapena ntchito zotengera masomphenya, a mafakitale PC kwa makina masomphenya kapena a PC yamakampani yokhala ndi GPU ikhoza kupereka mphamvu yowerengera yofunikira.
Ndibwino kuti mukuwerenga:
Kodi pali kusiyana kotani pakati pa 5.0, 5.1, 5.2, 5.3 bluetooth?
