Ukuze uxhume umqapha kwikhompyutha, izixhumi ezikhethekile zisetshenzisiwe, ezithengiswa ku-motherboard noma ezitholakala ekhadini levidiyo, namakhodi akhethekile afanele kulawaxhunyiwe. Enye yezinhlobo ezidume kakhulu zamapayipi namuhla ukubonisa ulwazi lwedijithali kumqapha we-computer yi-DVI. Kodwa ulahlekelwa phansi phambi kwe-HDMI, okuyinto isisombululo esithandwa kakhulu namuhla.
Ulwazi jikelele
Ama-DVI-connectors ayasebenza, ngakho-ke uma unquma ukwakha ikhompyutha ekuqaleni, kungcono ukuthola ibhodi le-motherboard nekhadi levidiyo elinamaxhumi amaningi anamuhla wokubonisa ulwazi lwedijithali. Kungcono kubanikazi bezihloli ezindala noma labo abangafuni ukusebenzisa imali yokukhetha amamodeli nge-DVI noma lapho ekhona. Njengoba i-HDMI yichweba elivame kakhulu, kunconywa ukukhetha amakhadi wehluzo namabhodi wamabhodi lapho.
Izinhlobo ze-HDIMI zokuxhuma
Idizayini ye-HDMI inezikhonkwane ezingu-19, inombolo yayo engafani nohlobo lwexhuma. Ingashintsha izinga lomsebenzi, kodwa izinhlobo zobuchwepheshe ngokwazo zihluka kuphela usayizi nobuchwepheshe lapho zisetshenziselwa khona. Nazi izici zazo zonke izinhlobo ezikhona:
- Thayipha i-A enkulu kakhulu futhi ethandwa kakhulu emakethe. Ngenxa yobukhulu bayo, ingafakwa kuphela kumakhompyutha, amathelevishini, ama-laptops, abaqaphi;
- Thayipha i-C - ithatha isikhala esingaphansi komlingani wayo omkhulu, ngakho-ke ingatholakala kumanothi athile wezincwadi, ezincwadini eziningi zamabhuku kanye namanye amaphilisi;
- Thayipha iDiskhi ye-HDMI encane kunazo zonke namuhla, eyakhelwe ngamaphilisi, ama-PDA kanye nama-smartphones;
- Kukhona uhlobo oluhlukile lwezimoto (ngokuqondile, ukuxhuma ikhompiyutha ebhodini namadivayisi ahlukahlukene angaphandle), enezivikelo ezikhethekile ezivela ku-vibration ezikhiqizwa yi-injini, izinguquko ngokuzumayo ekushiseni, ukucindezela, umswakama. Ichazwe incwadi yesiLatin E.
Izinhlobo ze-DVI zokuxhuma
Ku-DVI, inani labathintana nabo lixhomeke kuhlobo lomxhumanisi futhi luhluka kusuka oxhumana nabo abangu-17 ukuya ku-29, izinga le signal eliphumayo libuye lihluka kakhulu kuye ngezinhlobo. Izinhlobo ezilandelayo ze-DVI connectors okwamanje zisetshenzisiwe:
- I-DVI-A iyisixhumi esidala kunazo zonke futhi esinesidala esenzelwe ukudlulisela isignali ye-analog kubalindi basendulo (hhayi i-LCD!). Inama-17 kuphela oxhumana nabo. Ngokuvamile, kulaba balindi, isithombe siboniswa ngokusebenzisa ubuchwepheshe be-tube cathode ray, engakwazi ukubonisa isithombe esiphezulu (ikhwalithi ye-HD nokuphezulu) nokulimaza umbono;
- I-DVI-I iyakwazi ukukhipha kokubili isignali ye-analogue kanye neyedijithali eyodwa, umklamo uhlinzeka izikhonkwane ezingu-18 + ezingu-5, futhi kukhona isandiso esikhethekile, lapho izikhonkwane ezingu-24 eziyinhloko kanye no-5 ezengeziwe. Ingabonisa isithombe kufomethi ye-HD;
- I-DVI-D - eyenzelwe ukudluliswa kwesignali yedijithali kuphela. Umklamo ojwayelekile uhlinzeka izikhonkwane ezingu-18 + 1 ngaphezulu, okufakiwe kufaka phakathi izikhonkwane ezingu-24 + 1 ezengeziwe. Lena inguqulo yesimanje kunazo zonke zomxhumanisi, okungukuthi, ngaphandle kokulahlekelwa kwekhwalithi, iyakwazi ukuthumela izithombe ngesinqumo sama pixels ka-1980 × 1200.
I-HDMI inezinhlobo eziningana zezixhumi, ezihlukaniswa ngokulingana nobukhulu bokudluliselwa, kodwa zonke zisebenza kuphela nge-LCD display futhi zikwazi ukunikeza isignali ephezulu nekhwalithi kunabalingani babo be-DVI. Ukusebenza kuphela ngabakhokeli bedijithali kungabhekwa njengokubili nokunye. Isibonelo, kubanikazi bezihloli eziphelelwe yisikhathi - lokhu kuzoba yingozi.
Izici ezihlukile
Naphezu kokuthi izintambo zombili zisebenza ngokusebenzisa ubuchwepheshe obufanayo, kukhona ukungafani okubonakalayo phakathi kwabo:
- Ikhebula le-HDMI lidlulisela isithombe kuphela kwifomu ledijithali, kungakhathaliseki uhlobo lwesikhangisi. Futhi i-DVI inezinhlobo ezihlukahlukene zamaports asekela kokubili ukudluliswa kwesignali yedijithali ne-analog noma i-analog / digital kuphela. Kubanikazi bezilindi ezindala, okukhethwa kukho okungcono kungaba yi-port ye-DVI, futhi kulabo abanokuqapha nekhadi levidyo ezisekela isinqumo se-4K, i-HDMI ingaba yindlela enhle kakhulu;
- I-DVI iyakwazi ukusekela imifudlana eminingi, evumela ukuthi uxhumane nabaqaphi abaningi kwikhompyutha yakho ngesikhathi esisodwa, kuyilapho i-HDMI isebenza kahle ngokuqapha eyodwa kuphela. Kodwa-ke, i-DVI ingasebenza ngokujwayelekile ngeziqapheli eziningana ezinikezwe ukuthi isinqumo sabo asikho ngaphezu kwe-HD evamile (lokhu kusebenza kuphela ku-DVI-I no-DVI-D). Uma udinga ukusebenza kubakhokeli abaningi ngesikhathi esifanayo futhi unezidingo eziphezulu zekhwalithi yesithombe, ke unake isikhangiso se-DisplayPort;
- I-HDMI iyakwazi ukudlulisela umsindo ngaphandle kokuxhuma noma yikuphi ukushaya kwekhanda okungeziwe, kodwa i-DVI ayikwazi, okuyinto ngezinye izikhathi ebangela ukuphazamiseka okuphawulekayo.
Bheka futhi: Kuyini i-DisplayPort noma i-HDMI engcono
Kukhona ukungezwani okukhulu phakathi kwezici zezintambo. I-HDMI inezinhlobo eziningana zazo, ngayinye eyenziwe yento ethile futhi iyakwazi ukudlulisela isignali ngaphezu kwamade amade (isibonelo, i-fiber version idlulisela isignali kumamitha angaphezu kuka-100 ngaphandle kwezinkinga). Amakhodi we-Copper HDMI omthengi angaziqhayisa ubude bamamitha angama-20 kanye nemvamisa yokudlulisela kwama-Hz angu-60 ku-HD HD isinqumo.
Izintambo ze-DVI azizinhlobo eziningi. Emashalofini ungathola izinkambo kuphela zokusetshenziswa kwabathengi, ezenziwa ngethusi. Ubude bawo abudluli amamitha angu-10, kodwa ukusetshenziswa kwekhaya ubude bwanele. Ikhwalithi yokudlulisela cishe iyingqayizivele yobude bekhebula (ngaphezulu kokusombulula kwesikrini nenombolo yabaqaphi abaxhunyiwe). Izinga eliphansi lokuvuselela okubukeka kwesikrini se-DVI singama-22 Hz, okwanele ukubuka ngokukhululekile kwamavidiyo (ukungasho imidlalo). Imvamisa enkulu yi-165 Hz. Ukuze uthole umsebenzi okhululekile, umuntu unama-Hz angu-60, okuyinto lesi sixhumano esinikeza ngokulayisha okujwayelekile ngaphandle kwezinkinga.
Uma ukhetha phakathi kwe-DVI ne-HDMI, kungcono ukumisa ekugcineni, ngoba lesi simiso sinamuhla futhi sashintsha ngokuphelele amakhompyutha amasha nabaqaphi. Kulabo abanamakholi omdala kanye / noma amakhompiyutha, kunconywa ukuba banake i-DVI. Kungcono ukuthenga inketho lapho kokubili lezi zixhumanisi ziphakanyisiwe. Uma udinga ukusebenza nabalindi abaningi, kungcono ukunaka i-DisplayPort.
