Ukuhlaziywa Komehluko phakathi kwe-DVI-D ne-DVI-I Interfaces
Okuqukethwe
- 1. Isingeniso
- 2. DVI-D interface
- 3. DVI-I interface
- 4. Umehluko oyinhloko
- 5. Iziphakamiso Zokusebenza Ezisebenzayo
- 6. Isiphetho
1. Isingeniso
Kumakhompuyutha okulawula izimboni, ukuboniswa kwevidiyo kuyingxenye ebalulekile yokuqapha idatha, ukulawulwa kwenqubo nokuboniswa kolwazi. Ukuze uqinisekise ukucaca nokuzinza kwesithombe, kubalulekile ukukhetha isixhumi esibonakalayo esilungile. Phakathi kwazo, i-DVI-D ne-DVI-I yizinhlobo ezimbili ezivamile ze-digital video interfaces, kodwa ziyehluka ekusebenzeni nasekusetshenzisweni.
Lesi sihloko sihlose ukuhlola izici nomehluko walezi zixhumanisi ezimbili ngokujula ukuze usize abasebenzisi bakhethe isixazululo esingcono kakhulu sokubonisa sezinhlelo zokusebenza zokulawula izimboni.
2. DVI-D interface
I-interface ye-DVI-D iyisixhumi esibonakalayo esihlanzekile sokudlulisa isignali yedijithali. Ayisekeli amasiginali we-analog. Lesi sixhumanisi sivame ukuba nezikhonkwane ezifika kwangu-24 (kodwa zingabandakanyi izikhonkwane zokumisa ezimise okukanxantathu ngezansi) futhi zidlulisela amasignali edijithali kuphela. Ngenxa yesici sayo sokusekela amasiginali edijithali kuphela, isixhumi esibonakalayo se-DVI-D singanikeza okukhipha ividiyo okucacile lapho kuxhunywe kumadivayisi okubonisa edijithali njengamamonitha e-LCD.
3. DVI-I interface
Ngokungafani ne-DVI-D, isixhumi esibonakalayo se-DVI-I sivumelana nezimo kakhulu ngoba sisekela ukudluliswa kwakho kokubili amasignali e-analog nedijithali. I-interface ye-DVI-I inamaphini angu-29, okuhlanganisa isixhumi sesignali ye-analog enezimbobo ezine kanye namaqembu amabili wephini wesignali yedijithali enemigqa emibili, ehambisana nabaqaphi be-analog abadala kanye neziqaphi zesimanje zedijithali.
4. Umehluko oyinhloko
1. Uhlobo lwesiginali: Umehluko obaluleke kakhulu ukuthi i-DVI-D idlulisa amasignali edijithali kuphela, kuyilapho i-DVI-I ikwazi ukudlulisa amasignali e-analog namasignali edijithali. Isixhumi esibonakalayo se-DVI-I sinikeza ukuhambisana okungcono okubuyela emuva.
2. Ukuhambisana: Njengoba isixhumi esibonakalayo se-DVI-I sisekela amasignali e-analog, sinezinzuzo ekusebenzisaneni, okuvumela abasebenzisi ukuthi baxhume amadivayisi wokubonisa i-analog njengamamonitha e-CRT. Ngokuphambene, isixhumi esibonakalayo se-DVI-D sikhawulelwe kumadivayisi edijithali.
3. Isimo sokusetshenziswa: Ezinhlelweni zekhompuyutha yezimboni, uma isibonisi esiqondiwe noma idivayisi yokubonisa isekela kuphela okokufaka kwesignali yedijithali, isixhumi esibonakalayo se-DVI-D siyisinqumo esihle. Ngokuphambene nalokho, uma udinga ukuxhuma idivayisi yokubonisa ye-analog endala noma uma ungaqiniseki ngohlobo lwedivayisi yokubonisa, kufanele ukhethe i-interface ye-DVI-I.
4. Ikhwalithi yesithombe: Uma usebenzisa izisetshenziswa zokubonisa ezidijithali, zombili izixhumanisi zinganikeza izithombe zekhwalithi ephezulu. Kodwa-ke, ikhwalithi yesithombe ingase ithinteke uma ixhunywe kusiqaphi se-analog ngesixhumi esibonakalayo se-DVI-I, njengoba amasignali e-analog evame ukuphazamiseka.
5. Iziphakamiso Zokusebenza Ezisebenzayo
Lapho ukhetha isixhumi esibonakalayo sekhompuyutha yezimboni, uhlobo lwedivayisi yokubonisa kufanele lucatshangelwe kuqala. Ezimweni zesimanje zezimboni, isixhumi esibonakalayo se-DVI-D ngokuvamile siyanconywa ngoba siqinisekisa ukuhambisana nezibonisi zakamuva zedijithali futhi sinikeza izithombe ezicacile.
Kodwa-ke, uma ikhompuyutha yezimboni idinga ukusebenzisana nezinhlobo eziningi zamadivayisi wokubonisa, noma idinga ukunikeza ukuhambisana okuphezulu ngaphandle kokucacisa uhlobo lwedivayisi yokubonisa, isixhumi esibonakalayo se-DVI-I sizoba inketho efaneleke kakhudlwana.
Nokho, uma i- pc yezimboni yombono womshini idinga ukusebenzisana nezinhlobo eziningi zamadivayisi wokubonisa, noma idinga ukunikeza ukuhambisana okuphezulu ngaphandle kokucacisa uhlobo lwedivayisi yokubonisa, bese isixhumi esibonakalayo se-DVI-I sizoba inketho efaneleke kakhudlwana.
6. Isiphetho
Kafushane, kokubili ukuxhumana kwe-DVI-D ne-DVI-I kuyizindlela ezibalulekile zokukhipha ividiyo ezivame ukusetshenziswa amakhompyutha ezimboni. Umehluko phakathi kwazo usekutheni ziyawasekela amasiginali we-analog noma cha.
Isibonelo, izixazululo ezifana ne- i-advantech industrial pc noma i-advantech pc eshumekiwe zenzelwe izinhlelo zokusebenza ezahlukahlukene zezimboni, kufaka phakathi fanless industrial embedded pc ongakhetha futhi eziqinile i-industrial rack pc imiklamo. Lezi zinhlelo ziqinisekisa ukusebenza okuthembekile ezindaweni ezinokhahlo kuyilapho zibhekelela nesidingo esikhulayo i-industrial pc china izixazululo.
