Ukukhetha iprojektha efanele kubalulekile ekubukeni okucacile nangempumelelo kuzo zombili izilungiselelo zebhizinisi nezemfundo. Izigaba ezihlukene, izinketho zamalensi, nezinqumo zengeza ekudidekeni, okuthi ngokwezinga elithile, kube lula inqubo uma okuthandwayo kwenziwa kwacaca. Lo mhlahlandlela ulwela ukusiza ukujwayelanisa izici zeprojektha kuzidingo nendawo ezizungezile, uqinisekisa ukuzethemba ngenkathi kukhethwa iprojektha ngemva kokubamba zonke izici eziqinisekisiwe ngenjongo yokusebenzisa. Manje, ake sixoxe ngokuthi singakuthola kanjani ukulingana okuphelele kokusetha kwakho.
Iluphi Uhlobo Lweprojektha Olufanele Wena?
Izigaba ezahlukene zifaka i-DLP, i-LCD, nama-LED projectors. Amaphrojekhtha e-DLP adume ngezithombe ezibukhali, kuyilapho ama-LCD e-LCD anomkhawulo ekukhiqizeni imibala. Amaphrojektha e-LED anokusebenza kahle kwamandla kanye nempilo yokuphila, futhi. Njalo nquma ikhwalithi yesithombe, ukuphatheka, nenjongo ngaphambi kokukhetha. Ngokusetshenziswa okuvamile ekhaya, i-LED noma i-LCD iyona ndlela engcono kakhulu.
I-Portable vs Fixed Projectors
Kulabo umsebenzi wabo odinga ukuhamba, amaphrojektha aphathwayo akhethwe kahle ngenxa yokubumbana kwawo kanye nokupakishwa kwawo kalula. Amaphrojektha angaguquki alungele ukusetha isikhathi eside njengasemakilasini noma ezindaweni zasetiyetha zasekhaya ezinikezelwe. Ngokusebenza ngokusebenza, hamba nokulungisiwe; uma ukuguquguquka kuyilokho umsebenzisi akufunayo, khetha ephathekayo. Inketho engcono kakhulu incike kakhulu ekutheni iprojektha idinga ukuhanjiswa kaningi kangakanani. Sekukonke, ukulingana phakathi kokusebenziseka kalula nokusebenza okubonakalayo kubalulekile.
Ithiyetha Yasekhaya vs Ibhizinisi vs Ngaphandle
Iprojektha yetiyetha yasekhaya igxile kakhulu kwikhwalithi yesithombe nokuhambisana komsindo. Endabeni yamaphrojektha ebhizinisi, agcizelela ukugqama nezinketho zokuxhuma ukunikeza isethulo. Kumaprojektha angaphandle, ama-lumens aphezulu ayadingeka ukuze adlule ukukhanya okuzungezile. Cabanga ngendawo lapho uzobe usebenzisa khona iprojektha yakho kaningi. Isilungiselelo sisiza kakhulu ekunqumeni ukuhlukaniswa okuzofaneleka kakhulu izidingo zomuntu.
Ukuqondanisa Isixazululo Nezimfuneko Zakho
Ngaso sonke isikhathi cabangela uhlobo lokuqukethwe nosayizi wezilaleli lapho ukhetha ukulungiswa. Kunezinqumo ezintathu Ezivamile, okuhlanganisa i-QHD, i-FHD 1080P, ne-UHD 4k. Kubalulekile ukwazi umehluko wabo: I-QHD vs FHD vs UHD. Okuqukethwe kwe-HD okucatshangelwayo kwe-high-def noma izibonisi ezinkulu zizodinga ukulungiswa okuphezulu. Khetha i-HD noma ngaphezulu uma okuqukethwe kwakho kuqukethe imininingwane emihle njengamashadi. Ukulungiswa okuphansi kwanele ngezinjongo ezingezona ezisemthethweni ezinjengamakhathuni noma imibukiso yamaslayidi. Cabangela lokho ohlose ukukuphrojekthi njalo.
Ilensi yokuphrojetha.
Ukuqonda Ubukhulu Begumbi Nosayizi Wesikrini
Uma isikrini sinamathiselwe odongeni, yilapho iphrojektha ingahlala khona, futhi isithombe sizobukeka sikhulu. Ilensi inquma ibanga elingahlala iprojektha. Amalensi okujikijela ajwayelekile athatha isikhala esengeziwe ngobukhulu bekamelo, kuyilapho ama-lens okujikijela amafushane asebenza kangcono emakamelweni amancane. Amaphrojektha ama-Ultra-short-throw ahlala eduze kakhulu nesikrini. Khetha igumbi lakho kuzo zombili izilinganiso ngokusekelwe kusikrini osidingayo. Ububanzi bokusetha kwakho buzofakwa engozini uma ilensi isethwe njengephutha.
I-Lens Shift, Zoom & Keystone Correction
Nge-lens shift, ungakwazi ukususa isithombe ngaphandle kokushintsha indawo yeprojektha. Ukushintsha usayizi wesithombe kwenziwa ngokusondeza, futhi ukuhlanekezela kwesithombe kulungiswa ngokulungiswa kwetshe elingukhiye. Yonke le misebenzi ithuthukisa ukuguquguquka kokuma kweprojektha. Amaphrosesa amaningi ngeke ahlanganise konke ukulungisa; ngakho-ke, ukukhetha ngokucophelela kuyadingeka. Lezi zici zibalulekile; ziseshe, ikakhulukazi amalungiselelo angafanelekile noma asymmetric.
Ukuqondanisa Amapharamitha Omshini Nendawo Ezungezile
Amakamelo amancane azuza kumaphrojektha okuphonsa okufushane anezilungiselelo zokukhanya okuphansi. Amabanga amade, amahholo amakhulu, noma izilungiselelo zangaphandle zidinga ukukhanya okuphezulu namalensi okujikijela isikhathi eside. Cabangela umbala wodonga, amafasitela, nokuthi isikhala sakho singaba mnyama kangakanani. Imininingwane kufanele ifanelane nenani lokukhanya nosayizi wegumbi. Izinga lokusebenza iprojektha engayinikeza iqinisekiswa ngokusebenzisa imingcele ethile yemvelo.
Izici vs Intengo
Zonke izici eziqhathaniswa nokuqhathaniswa kwentengo kufanele zihlangabezane nezicaciso lapho kukhethwa ukuthi iyiphi iprojektha ozoyisebenzisa. Amaphrojekhtha asezingeni lokungena afika namasethi wesici se-bare-bones, ehlise amanani entengo; Nokho, ikhwalithi ingase ibe yinkinga. Amaphrojekhtha webanga elimaphakathi ashaya ibhalansi yesilinganiso esimaphakathi phakathi kwentengo nokusebenza. Amamodeli angochwepheshe aziqhenya ngokulungiswa okuphezulu, ukukhanya, nezinhlobonhlobo zamalensi. Hlela ibhajethi kuqala, bese unquma ukuthi yiziphi izici ezibaluleke kakhulu.
Izimpawu Zokugcina
Iprojektha yakho efaneleke kakhulu incike endaweni yakho ethile, uhlobo lokuqukethwe, kanye nesabelomali. Uhlobo lomsebenzi, noma ngabe ukubukwa kwemuvi, izethulo zamaslayidi, noma ukusingathwa kwemicimbi yangaphandle, konke kubhekwa ngenhlanganisela efanele yohlobo, isixazululo, kanye nokukhetha kwelensi ukuze imisebenzi yenziwe kalula. Hlala ucabangela indawo ezungezile kanye namaphethini akho okusebenzisa kuqala. Umzamo omncane ochithiwe ukufuna ulwazi uyakhokha. Yenza izinqumo zakho ngokuhlakanipha, futhi ukusebenza okuhlala isikhathi eside kuba isiqinisekiso.
Imibuzo Evame Ukubuzwa
Q2: Ingabe izindleko ezengeziwe ekulungisweni kwe-4K ziyafaneleka?
IMP: Impela, uma ubuka amamuvi noma udlala imidlalo yevidiyo esikrinini esikhulu.
Q3: Iyiphi ilensi efaneleke kakhulu kumakilasi amancane?
IMP: Okufanele kakhulu izikhala ezincane ukujikijela okufushane noma ilensi yokujikijela okufushane kakhulu.
I-Q4: Ingakanani inombolo efanelekile yama-lumens okubukwayo ngaphandle?
A: Awekho ama-lumens angaphansi kuka-3000 amukelekayo ezindaweni ezingaphandle ezikhanyiswe ngokugqamile.
