Iyiphi iprojektha yasekhaya okufanele uyikhethe?

Iprojektha isiba enye indlela ethandwa kakhulu kune-TV. Yini okufanele uyibheke lapho ukhetha i-projektha? Hlola amapharamitha abaluleke kakhulu okufanele uwahlole lapho uthenga izinto zokusebenza.

Ukusetshenziswa kwama-multimedia projector kunesiko elide, nakuba esikhathini esingeside esidlule le mishini yayibusa kakhulu ezikoleni. Namuhla iyindawo ethandwa kakhulu esikhundleni se-TV - isebenziseka kalula, ithatha indawo encane futhi iqinisekisa isithombe esikhulu kunamamodeli we-TV amade kakhulu emakethe.

Ngosizo lweprojektha, awukwazi ukubuka ama-movie kuphela futhi usebenzise izinsizakalo zokusakaza, kodwa futhi udlale imidlalo. Le divayisi enemisebenzi eminingi ilungele labo abafuna umuzwa wokugcina wokubuka ngaphandle kokutshala imali ezintweni ezibizayo, ezinkulu. Kodwa-ke, ukuthi ungasebenzisa kanjani i-projektha kuncike kuzixazululo ezisetshenziswa kuyo. Iyiphi iprojektha yasekhaya okufanele uyikhethe? Kuncike kakhulu kulokho okuncamelayo kwesithombe sakho kanye nesikhala onawo. Ake sihlaziye amanye amapharamitha abaluleke kakhulu okufanele abe nomthelela ekukhethweni kwemishini.

Isiphi isinqumo esifanele seprojektha yasekhaya? 

Ukulungiswa kubalulekile uma usebenzisa i-overhead projector ukuze ubuke amafilimu noma udlale imidlalo. Lena ipharamitha eveza inani lamaphikseli aqondile futhi avundlile. Ikhwalithi yesithombe esibonisiwe incike kakhulu kulokhu. Uma kukhulu ukuminyana kwabo, kuzoba bukhali. Amaphrojektha asetshenziswa ezikoleni noma ezingqungqutheleni ukukhombisa izethulo angase abe nesinqumo esiphansi, kodwa isinqumo esiphezulu sizodingeka ekhaya.

Okuncane kungu-1280 × 720 (okujwayelekile kwe-HD). Lawa maphrojekhtha ajwayele ukuthengeka, njengemodeli ye-Phillips NeoPix Easy2. Uma ikhwalithi yesithombe ephezulu ibalulekile kuwena, kufanelekile ukutshala ku-Full HD noma i-4K. Qaphela, nokho, ukuthi amanani entengo alezi zimvume ezimbili akude kakhulu. Ungathenga iprojektha enhle ye-Full HD multimedia engaphezulu nje kwe-PLN 1000 (bheka i-Optoma HD146X isibonelo), kuyilapho iprojektha yokuxazulula ye-4K efana ne-Acer's H6815BD noma i-BenQ's W1720 ibiza ngaphezu kwe-PLN 5000.

Ifomethi yesithombe - yini ezosebenza ekhaya?

Amaphrojektha angabonisa izithombe ngezilinganiso ezintathu ezihlukene - 4:3, 16:10, noma 16:9 (i-aspect ratio yesikrini esibanzi ehlanganisa, isibonelo, i-EPSON EH-TW5700). Ngenxa yobubanzi bayo, le yokugcina izoba yisinqumo esingcono kakhulu semidlalo yaseshashalazini yasekhaya. Kodwa-ke, uma uthola iprojektha enhle engu-16:10, ungaphinda utshale imali eyodwa ngaphandle kokukhathazeka ngokubuka ukunethezeka. Kodwa gwema ifomethi engu-4:3, elungele izikole noma izinkomfa, kodwa hhayi ngezinjongo zetiyetha yasekhaya.

Uhlobo lomthombo wokukhanya - liyithinta kanjani ikhwalithi yesithombe?

Iprojektha yasekhaya ingasebenzisa eyodwa yezinhlobo ezimbili zemithombo yokukhanya, noma zombili. Eyokuqala ama-LED, kanti eyesibili i-laser. Uhlobo lokukhanya olusetshenziswa empahleni ethile luncike, phakathi kwezinye izinto, empilweni yesisetshenziswa noma esilinganisweni sokungafani. Ama-LED aqinisekisa ukusebenza kahle kwamandla, kodwa isithombe esikhishwa ngokusetshenziswa kwawo singase sibe sibi kakhulu ngekhwalithi. Izisetshenziswa ezisuselwe kuma-LED kuphela ngokuvamile azihlali isikhathi eside.

Ukusetshenziswa kwe-laser beam kuqinisekisa impilo ende yesevisi kanye nekhwalithi ephezulu yesithombe. Lesi sixazululo sisetshenziswe, phakathi kwezinye izinto, ochungechungeni lwe-Xiaomi Mi Laser, oluphinde luhlukanise nokusetshenziswa kobuchwepheshe bokucubungula ukukhanya kwedijithali. Nokho, lawa mamodeli abiza kakhulu. Ukuhwebelana kungase kube ukukhetha iprojektha ehlanganisa i-laser ne-LED futhi ethengekayo kancane.

Izinhlobo zamachweba - yiziphi ezizoba usizo?

Iprojektha yasekhaya enamachweba amaningi ahlukene ahlanganisa i-HDMI, i-USB, i-AV, i-stereo noma i-mini jack iwutshalomali oluhle. Inketho yokuxhumana okungenantambo nge-Bluetooth noma i-Wi-Fi ingaba yisixazululo esikahle.

Ubuchwepheshe bokubonisa izithombe - i-LCD noma i-DLP?

I-DLP ubuchwepheshe obusetshenziswa kalula kuma-premium projektha. Isekelwe ohlelweni lwezibuko ezincane lapho ukukhanya kudlula khona. Umphumela wale mishini uyisithombe esinemibala emihle kakhudlwana, ukugqama okulingana kahle, nokumanzi okuphezulu. Inzuzo enkulu ye-DLP ukuthi amaphikseli awabonakali kancane kunase-LCD.

Okuhlukile kwe-LCD kusebenzisa ubuchwepheshe bokubonisa obuhluke kancane. Esimeni sakhe, ukukhanya okukhishwa amalambu e-CCFL, ahlungwe ama-polarizer, kushaya i-crystal matrix ewuketshezi. Lesi sixazululo sisetshenziswe, phakathi kwezinye izinto, kumodeli ye-OWLENZ SD60, ehlukaniswa ngokukwazi ukuthengeka. Inzuzo yayo engenakuphikwa ukusetshenziswa kwamandla okuphansi. Uma ukhetha i-LCD, ungabheka phambili nokucaca kwesithombe, imibala ecebile ngisho nokukhanya.

Ibanga elincane neliphezulu - kanjani ukuthola incazelo yegolide?

Le pharamitha incike ngokuyinhloko kubude bokugxila beprojektha. Lapho ubude bendawo bufushane, yilapho iphrosesa isondelana nesikrini (ngaphandle kokulahlekelwa ikhwalithi yesithombe). Ekhaya, amamodeli anobude obufushane bokugxila aphelele, angabekwa eduze kwesikrini noma alengiswe eduze kodonga olusebenza njengendiza yokubonisa. Kungani ibalulekile? Lapho iseduze, ingozi encane yokuvela kwezithunzi esithombeni.

Iprojektha iyindlela ehlukile ye-TV, ngenxa yalokho ongajabulela isithombe esihle ngekhwalithi enhle kakhulu. Landela amathiphu ethu futhi ngokuqinisekile uzothola imodeli ephelele kuwe!
