Ukuxhuma ukubheka kwikhompyutha, kusetshenziswa izixhumi ezikhethekile ezidayiswa kubhodi ye-mama noma etholakala ekhadini levidiyo, nezintambo ezikhethekile ezifanele laba baxhumi. Enye yezinhlobo ezaziwa kakhulu zamachweba namuhla zokukhipha imininingwane yedijithali kuqapha lekhompyutha yi-DVI. Kepha ulahlekelwa ngumhlaba phambi kwe-HDMI, namuhla esiyikhambi elaziwa kakhulu.
Imininingwane ejwayelekile
Izixhumi ze-DVI ziqala ukuphelelwa yisikhathi, ngakho-ke uma unquma ukwakha ikhompyutha kusuka ekuqaleni, lapho-ke kungcono ukubheka ikhadi lomama nekhadi levidiyo eliqukethe izixhumi eziningi zanamuhla zokuphuma kolwazi lwedijithali. Kubanikazi babaqaphi bakudala noma abangafuni ukusebenzisa imali, kungcono ukhethe imodeli ene-DVI noma lapho ikhona. Njengoba i-HDMI iyitheku elivame kakhulu, kungakuhle ukhethe amakhadi wevidiyo namakhamera we-mama lapho ikhona.
Izinhlobo Zesixhumi ze-HDIMI
Idizayini ye-HDMI inikela ngoxhumana nabo abayi-19, inani lazo elingashintshi kuya ngohlobo lwesixhumi. Kuwo, ikhwalithi yomsebenzi ingashintsha, kepha izinhlobo zokuxhumana ngokwazo zihlukile kuphela ngosayizi nemishini esetshenziswa kuyo. Nazi izici zazo zonke izinhlobo ezikhona:
- Uhlobo A luyinto enkulu kunazo zonke futhi ethandwa kakhulu emakethe. Ngenxa yobukhulu bayo ingafakwa kumakhompyutha kuphela, kumabonakude, kuma-laptops, kubaqaphi;
- Uhlobo C - kuthatha isikhala esincanyana kunezakwabo ezinkulu, ngakho-ke kungatholakala kaningi kumamodeli athile e-laptop, emabhukwini amaningi e-netbooks nakwamanye amaphilisi;
- Uhlobo D - isixhumi esincane kunazo zonke se-HDMI kuze kube manje, esakhelwe kumathebhulethi, ama-PDA ngisho nama-smartphones;
- Kunohlobo oluhlukile lwezimoto (ngokuqondile, lokuxhuma ikhompyutha esebhodini ngamadivayisi ahlukahlukene angaphandle), elinokuvikelwa okukhethekile ekuvumelaniseni okukhiqizwa yinjini, ushintsho olungazelelwe lokushisa, ingcindezi, umswakama. Kushiwo incwadi yesiLatini u-E.
Izinhlobo Zesixhumi ze-DVI
Kwi-DVI, inani lezikhonkwane lincike ohlotsheni lwesixhumi futhi lihluka kusuka kumapini ayi-17 kuye kwangama-29, ikhwalithi yesiginali ekhishwayo nayo iyahlukahluka kakhulu ngokuya ngezinhlobo. Njengamanje, kusetshenziswa izinhlobo ezilandelayo zezixhumi ze-DVI:
- I-DVI-A isixhumi sakudala nesidala kakhulu esenzelwe ukudlulisela isiginali ye-analog kubaqaphi abadala (hhayi i-LCD!). Inabothintana abangu-17 kuphela. Imvamisa, kulezi ziqapha, isithombe sikhonjiswa kusetshenziswa ubuchwepheshe be-cathode ray tube, esingakwazi ukuphuma isithombe sekhwalithi ephezulu (ikhwalithi ye-HD nangaphezulu) futhi siyingozi embonweni;
- I-DVI-I - ekwazi ukukhipha zombili amasiginali we-analog nezedijithali, lo mklamo uhlinzeka ngoxhumana nabo abangu-18 + 5 okungeziwe, kukhona nesandiso esikhethekile, lapho oxhumana nabo abaphambili abangama-24 nabangu-5 abengeziwe. Ungakhombisa isithombe ngefomethi ye-HD;
- I-DVI-D - yenzelwe ukudluliswa kwesiginali yedijithali kuphela. Idizayini ejwayelekile inikeza oxhumana nabo abangu-18 + 1 abengeziwe, enwetshiwe ifaka oxhumana nabo abangama-24 + 1 abengeziwe. Le yinguqulo yesimanje kakhulu yesixhumi, okuthi ngaphandle kokulahleka kwekhwalithi ikwazi ukudlulisela izithombe kusixazululo samaphikseli we-1980 × 1200.
I-HDMI futhi inezinhlobo eziningi zezixhumi ezihlukaniswa ngosayizi nekhwalithi yokudlulisela, kepha zonke zisebenza kuphela ngombukiso we-LCD futhi ziyakwazi ukuhlinzeka ngekhwalithi ephezulu nekhwalithi yesithombe ngokuqhathaniswa nabalingani babo be-DVI. Ukusebenza kuphela nabaqaphi bedijithali kungabhekwa njengokuhlanganisa kanye nokuncane. Isibonelo, kubanikazi bamaqapha asephelelwe yisikhathi - lokhu kuzoba nzima.
Izici ezihlukanisayo
Naphezu kweqiniso lokuthi womabili amakhebuli asebenza kubuchwepheshe obufanayo, anokungafani okubonakalayo phakathi kwawo:
- Intambo ye-HDMI idlulisa kuphela izithombe ngokomfanekiso, kungakhathalekile ukuthi hlobo luni lwesixhumi. Futhi i-DVI inamachweba ahlukahlukene axhasa ukuhanjiswa kwesiginali yedijithali, kanye ne-analog noma i-analog / digital kuphela. Kwabanikazi bama-monitors amadala, itheku le-DVI lizoba inketho ezinhle kakhulu, futhi kulabo abanekhadi lokuqapha nekhadi levidiyo elisekela ukulungiswa kwe-4K, i-HDMI kuzoba inketho enhle;
- I-DVI iyakwazi ukuxhasa ukusakazwa okuningi, okukuvumela ukuthi uxhume ama-monitor amaningi kwikhompyutha ngasikhathi sinye, kanti i-HDMI isebenza kahle nge-track eyodwa kuphela. Kodwa-ke, i-DVI ingasebenza ngokufanele ngabaqaphi abaningi, inqobo nje uma ukulungiswa kwabo kungaphakeme kune-HD ejwayelekile (lokhu kusebenza kuphela ku-DVI-I ne-DVI-D). Uma udinga ukusebenza ngokuqapha amaningi ngasikhathi sinye futhi unezidingo eziphakeme zekhwalithi yesithombe, ke unaka isixhumi se-DisplayPort;
- Ubuchwepheshe be-HDMI buyakwazi ukusakaza umsindo ngaphandle kokuxhuma amanye amahedisethi, futhi i-DVI ayikwazi lokhu, kwesinye isikhathi okubangela ukuphazamiseka okukhulu.
Bheka futhi: Yini engcono kune-DisplayPort noma i-HDMI
Kunokwehluka okungathi sína kokucaciswa kukhebula. I-HDMI inezinhlobo eziningi zazo, ngamunye enziwe ngento ethile futhi uyakwazi ukudlulisa isiginali ngaphezulu kwamabanga amade (ngokwesibonelo, inketho kusuka ku-fiber optic idlulisela isiginali iye kumamitha angaphezu kwezi-100 ngaphandle kwezinkinga). Izintambo zethusi ze-HDMI zethusi ziqhenya ngamamitha angama-20 ngobude kanye nobuningi bokuhanjiswa kwe-60 Hz kusisombululo se-Ultra HD.
Izintambo ze-DVI azihlukile kakhulu. Emashalofini ungathola izintambo kuphela zokusetshenziswa okubanzi, ezenziwe ngethusi. Ubude bawo abudluli kumamitha ayi-10, kepha ukusetshenziswa kwasekhaya lokhu kwanele. Ikhwalithi yokudlulisela imele ngokuphelele kubude bekhebula (okuningi kusisombululo sesikrini kanye nenani lamaqapha axhunyiwe). Inani eliphansi lokuqabuleka lesikrini se-DVI yi-22 Hz, enganele ukubukwa okunethezekile kwamavidiyo (ingasaphathwa imidlalo). Imvamisa ephezulu yi-165 Hz. Ngomsebenzi okhululekile, i-60 Hz yanele kumuntu, okuthi kumthwalo ojwayelekile lesi sixhumanisi sihlinzeka ngaphandle kwezinkinga.
Uma ukhetha phakathi kwe-DVI ne-HDMI, kungcono ukugxila kulokhu okugcina, ngoba leli zinga lingelesimanje futhi lishintshwe kahle amakhompyutha amasha nabaqaphi. Kulabo abane-monitor ezindala kanye / noma amakhompyutha, kungakuhle ukuthi unake i-DVI. Kuhle ukuthenga inketho lapho zombili lezi zixhumi zibekwe khona. Uma udinga ukusebenza ngokuqapha amaningi, ke unake kangcono i-DisplayPort.
