Kuti mulumikizitse polojekiti pa kompyuta, amalumikiza apadera amagwiritsidwa ntchito omwe amagulitsidwa pa bolodi la amayi kapena omwe ali pa khadi ya kanema, ndi zingwe zapadera zoyenera zolumikizira izi. Mtundu wodziwika wa madoko masiku ano potulutsa zidziwitso zamagetsi pakompyuta ya Datc ndi DVI. Koma akutaya pansi kutsogolo kwa HDMI, yomwe lero ndi yankho lotchuka kwambiri.
Zambiri
Maalumikizidwe a DVI amayamba kukhala otha ntchito, chifukwa chake ngati mungaganize zomanga kompyuta kuchokera pachiwonetsero, ndiye kuti kuli bwino kufunafuna khadi ya amayi ndi makanema omwe ali ndi zolumikizira zamakono kuti atulutsire zambiri. Kwa eni oyang'anira akale kapena omwe safuna kugwiritsa ntchito ndalama, ndibwino kuti musankhe mawonekedwe ndi DVI kapena komwe ilipo. Popeza HDMI ndiye doko lofala kwambiri, ndikofunikira kusankha makadi a vidiyo ndi matepi a amayi komwe kuli.
Mitundu yolumikizira ya HDIMI
Kapangidwe ka HDMI kamapereka mafoni 19, kuchuluka kwake komwe sikusintha kutengera mtundu wa wolumikizira. Kuchokera pamenepo, mtundu wa ntchito umatha kusintha, koma mitundu ya mawonekedwe pawokha imasiyana mu kukula kwake ndi zida zomwe zimagwiritsidwa ntchito. Nayi mawonekedwe a mitundu yonse yomwe ilipo:
- Mtundu A ndiye wamkulu komanso wotchuka kwambiri pamsika. Chifukwa cha kukula kwake imatha kuyikidwa m'makompyuta, ma TV, ma laputopu, oyang'anira;
- Mtundu C - umatenga malo ocheperako kuposa mzawo wokulirapo, kotero nthawi zambiri umatha kupezeka mumitundu yapa laputopu, mumabookbook ambiri ndi mapiritsi ena;
- Mtundu D - cholumikizira chaching'ono kwambiri cha HDMI mpaka pano, chomwe chimapangidwa m'mapiritsi, PDA ngakhale mafoni;
- Pali mtundu wina wamagalimoto (ndendende, wolumikiza kompyuta pa komputa ndi zida zina zakunja), yomwe imakhala ndi chitetezo chapadera ku kugwedezeka komwe kumapangidwa ndi injini, kusintha mwadzidzidzi kutentha, kupanikizika, chinyezi. Amanenedwa ndi kalata yachilatini E.
Mitundu yolumikizira ya DVI
Kwa DVI, kuchuluka kwa zikhomo kumadalira mtundu wa wolumikizira ndikusiyana ndi zikhomo 17 mpaka 29, mtundu wa chizindikiro chotulutsa umasiyananso kwambiri kutengera mitundu. Pakadali pano, mitundu yotsatira yolumikizira DVI imagwiritsidwa ntchito:
- DVI-A ndiye cholumikizira chakale kwambiri komanso choyambirira chomwe chimapangidwa kuti chisagulitse chizindikiro cha analog kwa owunika okalamba (osati LCD!). Ili ndi mayanjano 17 okha. Nthawi zambiri, mumawunikidwe awa, chithunzicho chikuwonetsedwa pogwiritsa ntchito ukadaulo wa cathode ray chubu, womwe sungathe kutulutsa chithunzi (chamtundu wapamwamba komanso wapamwamba) wa HD ndipo ndivulaza kuwona;
- DVI-I - wokhoza kutulutsa ma analog ndi ma signature a digito, kapangidwe kameneka kamalumikizana ndi 18 + 5 zowonjezera, palinso zowonjezera zapadera, komwe kulumikizana kwakukulu 24 ndi 5 zowonjezera. Itha kuwonetsa chithunzi mu mtundu wa HD;
- DVI-D - yopangidwira mauthenga a digito kokha. Kapangidwe kameneka kamakhala ndi olemba 18 + 1 ena, omwe amakuphatikiza akuphatikiza ojambula 24 + 1 ndi zina. Ili ndiye mtundu wamakono koposa wolumikizira, womwe popanda kutayika kwa mawonekedwe amatha kutumizira zithunzi mukugwirizana kwa pixels za 1980 × 1200.
HDMI ilinso ndi mitundu ingapo yolumikizira yomwe imasankhidwa ndi kukula komanso mtundu wa kufalitsa, koma onsewa amangogwira ntchito ndi zowonetsera za LCD ndipo amatha kupereka mawonekedwe apamwamba komanso mawonekedwe apamwamba poyerekeza ndi anzawo a DVI. Gwirani ntchito kokha ndi owunikira a digito omwe titha kuwaona ngati kuphatikiza ndi opanda. Mwachitsanzo, kwa eni zowonera zakale - izi zingakhale zovuta.
Zosiyanitsa
Ngakhale zingwe zonse ziwiri zimagwira ntchito paukadaulo womwewo, ali ndi kusiyana kwakukulu pakati pawo:
- Chingwe cha HDMI chimangotumiza zithunzi pamakina, mosasamala mtundu wa cholumikizira. Ndipo DVI ili ndi ma doko osiyanasiyana omwe amathandizira kutumiza ma siginito pa digito, ndi analog kapena kokha analog / digito. Kwa eni zowunikira zakale, doko la DVI lidzakhala njira yabwino kwambiri, ndipo kwa iwo omwe ali ndi khadi loyang'anira ndi makanema omwe amathandizira chisankho cha 4K, HDMI idzakhala njira yabwino;
- DVI imatha kuthandizira mitsinje ingapo, yomwe imakulolani kulumikiza owunika angapo pakompyuta nthawi imodzi, pomwe HDMI imagwira ntchito molondola ndi wowunika m'modzi. Komabe, DVI imatha kugwira ntchito moyenera ndi owunikira angapo, malinga ndi momwe malingaliro awo sakhala apamwamba kuposa HD yokhazikika (izi zimangogwira DVI-I ndi DVI-D). Ngati mukufunikira kuyang'anira owunika angapo nthawi imodzi ndipo muli ndi zofunikira pazithunzithunzi, ndiye kuti mukulumikizana ndi cholumikizira cha DisplayPort;
- Tekinoloji ya HDMI imatha kufalitsa mawu popanda kulumikiza mahedifoni ena owonjezera, ndipo DVI siyitha izi, zomwe nthawi zina zimayambitsa kusokonezeka kwakukulu.
Onaninso: Zomwe zili bwino kuposa DisplayPort kapena HDMI
Pali zosiyana zazikulu pamatchulidwe amtambo. HDMI ili ndi mitundu ingapo ya iyo, iliyonse yomwe imapangidwa ndi zinthu zina ndipo imatha kutumiza chizindikiro pamtunda wautali (mwachitsanzo, njira kuchokera ku fiber optic imayendetsa chizindikiro kupitirira mamitala 100 popanda mavuto). Zingwe za mkuwa za Consumer-grade HDMI zimadzitama mpaka 20 metres kutalika ndi 60 Hz kufalitsa pafupipafupi mu Ultra HD resolution.
Zingwe za DVI sizosiyana kwambiri. Patsamba pansipa mungapeze zingwe zokha zogwiritsidwa ntchito kwambiri, zomwe zimapangidwa ndi mkuwa. Kutalika kwawo sikudutsa mita 10, koma kugwiritsa ntchito nyumba kutalika kwake ndikokwanira. Mtundu wa kaperekedwe umakhala wopanda kutalika kwa chingwe (zambiri pazosintha mawonekedwe ndi kuchuluka kwa owunika). Mlingo wocheperako womwe ungakhalepo pazenera la DVI ndi 22 Hz, zomwe sizokwanira kuwona makanema (osanenapo masewera). Kutalika kwakukulu ndi 165 Hz. Pa ntchito yabwino, 60 Hz ndi yokwanira kwa munthu, yomwe mwaulemu yolumikizira iyi imapereka popanda mavuto.
Ngati mungasankhe pakati pa DVI ndi HDMI, ndibwino kungoyang'ana zakumbuyo, popeza muyezo ndi wamakono komanso wogwiritsa ntchito makompyuta atsopano komanso oyang'anira. Kwa iwo omwe ali ndi owunikira okalamba ndi / kapena makompyuta, ndikofunikira kuti mutchere khutu ku DVI. Ndikofunika kugula njira yomwe yolumikizira zonsezi imayikidwa. Ngati mukufunikira kuyang'anira oyang'anira angapo, ndiye kuti muyenera kulabadira DisplayPort.
