Kuti mugwirizane ndi makompyuta pamakina, makompyuta apadera amagwiritsidwa ntchito, omwe amagulitsidwa ku bolodi lamasewera kapena omwe ali pa khadi la kanema, ndi matepi apadera oyenerera awa. Mmodzi mwa mitundu yotchuka kwambiri yamakono masiku ano kuti asonyeze chidziwitso cha digito pa kompyuta kuyang'ana ndi DVI. Koma akutha kutsogolo kwa HDMI, yomwe ili njira yodziwika kwambiri lero.
Mfundo zambiri
DVI-connectors akukhala osagwiritsidwa ntchito, kotero ngati mwasankha kumanga makompyuta pachiyambi, ndi bwino kupeza makina ojambula mavidiyo ndi makanema omwe ali ndi zolumikiza zamakono zowonetsera chidziwitso cha digito. Ndi bwino kwa eni oyang'anira akale kapena omwe safuna kugwiritsa ntchito ndalama kuti asankhe DVI kapena kumene kuli. Popeza HDMI ndi malo otchuka kwambiri, ndi bwino kusankha makadi a makanema ndi mabotolo komwe kuli.
Mitundu yowonjezera ya HDIMI
Mapangidwe a HDMI ali ndi mapepala 19, chiĊµerengero chake sichisiyana ndi mtundu wothandizira. Zingasinthe khalidwe la ntchito, koma mawonekedwe a mawonekedwewa amasiyana ndi kukula ndi teknoloji yomwe amagwiritsidwa ntchito. Nazi makhalidwe a mitundu yonse yomwe ilipo:
- Mtundu A ndi waukulu kwambiri komanso wotchuka kwambiri pamsika. Chifukwa cha kukula kwake, zimangokhazikitsidwa pa makompyuta, makanema, makompyuta, oyang'anira;
- Mtundu C - umatenga malo ocheperapo kusiyana ndi wothandizana nawo wamkulu, kotero amatha kupezeka m'mabuku ena am'buku, m'mabuku ambirimbiri ndi mapiritsi ena;
- Mtundu D ndidongosolo laling'ono la HDMI lero, lomwe lamangidwa mu mapiritsi, PDAs ngakhale mafoni a m'manja;
- Pali mtundu wosiyana wa magalimoto (zowonjezereka, kugwirizanitsa makompyuta apakati ndi zipangizo zosiyanasiyana zakunja), omwe ali ndi chitetezo chapadera kuchokera ku kugwedeza kopangidwa ndi injini, mwadzidzidzi kusintha kutentha, kuthamanga, chinyezi. Zimatchulidwa ndi kalata yachilatini E.
DVI mawonekedwe mawonekedwe
Mu DVI, chiwerengero cha oyanjana chimadalira mtundu wa chojambulira ndipo chimasiyana pakati pa 17 ndi 29 olankhulana, khalidwe la chiwonetsero cha chizindikiro chimasiyanasiyana kwambiri malingana ndi mitundu. Mitundu yotsatira ya DVI yolumikizira ikugwiritsidwa ntchito:
- DVI-A ndi chojambulira chakale kwambiri komanso chachikulu kwambiri chomwe chinapangidwa kuti apereke chizindikiro cha analog kwa oyang'anira akale (osati LCD!). Ili ndi maulendo 17 okha. Kawirikawiri, m'magulu awa, chithunzichi chimagwiritsidwa ntchito pogwiritsa ntchito kachipangizo kachipangizo cha tube, chomwe sichikhoza kusonyeza chithunzi chapamwamba (HD ndipamwamba) ndi kuwononga masomphenya;
- DVI-I amatha kupanga ponseponse chizindikiro cha analogue ndi digito imodzi, kamangidwe kamapereka mapepala 18+ owonjezereka, palinso kutambasulidwa kwina, kumene kuli mapiritsi 24 ndi zina zisanu. Ikhoza kusonyeza chithunzichi mu mawonekedwe a HD;
- DVI-D - yokonzedwa kuti iwonetsere majambulidwe a digito yekha. Zojambulazo zimapereka mapepala 18+, zina zowonjezerapo zikuphatikizapo mapepala 24 + 1 owonjezera. Izi ndizomwe zimagwiritsidwa ntchito kwambiri masiku ano, zomwe, popanda kutaya khalidwe, zimatha kutumiza zithunzi pamasikisili a 1980 × 1200.
HDMI imakhalanso ndi mitundu yosiyanasiyana ya zolumikizira, zomwe zimagawidwa molingana ndi kukula ndi kapangidwe ka kachilombo ka HIV, koma zonse zimagwira ntchito ndi ma LCD ndipo zimatha kupereka chizindikiro chapamwamba ndi chithunzi kusiyana ndi anzawo a DVI. Gwiritsani ntchito ndi oyang'anitsitsa pa digito akhoza kuwonedwa ngati kuphatikiza ndi kuchepetsedwa. Mwachitsanzo, kwa eni oyang'anira nthawi - izi sizikhala zovuta.
Zosiyana
Ngakhale kuti zingwe zonsezi zimagwiritsa ntchito zipangizo zamakono, pali kusiyana kwakukulu pakati pawo:
- Khwimayi ya HDMI imapereka fanoyo mwa mawonekedwe a digito, mosasamala mtundu wa chojambulira. Ndipo DVI ili ndi zidole zosiyanasiyana zomwe zimathandizira kutumiza ma signal ndi analog kapena analog / digito. Kwa eni ake oyang'anira akale, njira yabwino kwambiri ikanakhala phukusi la DVI, komanso kwa omwe ali ndi khadi komanso makanema omwe amathandizira kukonza 4K, HDMI ingakhale njira yabwino kwambiri;
- DVI ikhoza kuthandizira mitsinje yambiri, yomwe imakulolani kuti mugwirizane ndi mawonekedwe ambiri pa kompyuta yanu kamodzi, pamene HDMI imagwira ntchito molondola pokhapokha ndikuyang'ana limodzi. Komabe, DVI ikhoza kugwira ntchito moyenera ndi maulendo angapo omwe amawonetsa kuti chigamulo chawo sichiri chokwanira kuposa HD (izi zimagwiritsidwa ntchito pa DVI-I ndi DVI-D). Ngati mukufuna kugwira ntchito pa maulendo angapo panthawi imodzimodzi ndipo muli ndi zofuna zapamwamba pazithunzi, ndiye mverani khutu la DisplayPort;
- HDMI imatha kusuntha phokoso popanda kulumikiza makutu ena onse, koma DVI silingathe, yomwe nthawi zina imayambitsa zovuta zazikulu.
Onaninso: Kodi ndi bwino DisplayPort kapena HDMI
Pali kusiyana kwakukulu mu zikhalidwe za zingwe. HDMI ili ndi mitundu ingapo ya izo, iliyonse yomwe imapangidwa ndi zinthu zina ndipo imatha kutumiza chizindikiro pambali yayitali (mwachitsanzo, fiber version imatumiza chizindikiro kwa mamita oposa 100 popanda mavuto). Zipangizo zamakono za HDMI zogulira zingadzitamande kutalika kwa mamita 20 ndi mafupipafupi a 60 Hz mu Ultra HD yankho.
Zipangizo za DVI zilibe zosiyanasiyana. Pa masamulo mungapeze zingwe zokha zogulira, zomwe zimapangidwa ndi mkuwa. Kutalika kwawo sikudutsa mamita 10, koma kwagwiritsiridwa ntchito kwa kutalika kwake ndikwanira. Mtundu wa kachilomboka umakhala wosiyana ndi kutalika kwa chingwe (zambiri pamasewero a chithunzi ndi chiwerengero cha oyang'anitsitsa ogwirizana). MaseĊµera osachepera omwe amatha kuwonekera pawindo la DVI ndi 22 Hz, zomwe sizikwanira kuti muwonere mavidiyo (osatchula masewera). Kuthamanga kwafupipafupi ndi 165 Hz. Kuti munthu azitha kugwira bwino ntchito, munthu ali ndi Hz 60, zomwe zimagwirizanitsa ntchitoyi popanda mavuto.
Ngati mutasankha pakati pa DVI ndi HDMI, ndi bwino kuima pamapeto pake, popeza muyeso uwu ndi wamakono komanso wokonzedweratu makompyuta atsopano ndi oyang'anira. Kwa omwe ali ndi akuluakulu oyang'anira komanso / kapena makompyuta, ndibwino kuti amvetsetse DVI. Ndi bwino kugula njira yomwe onse ogwiritsira ntchitowa ali pamwamba. Ngati mukufuna kugwira ntchito ndi owonetsa ambiri, ndi bwino kumvetsera DisplayPort.
