Vhidhiyo projector yakamboshandiswa sehurukuro yekushandisa mune zvebhizinesi uye zvekutsvaga mune zvebhizimisi, pamwe chete mune imwe nzvimbo yakakwirira-yekupedzisira yemitambo yemitambo. Zvisinei, vhidhiyo mapurojekiti ari kuwedzera kuwanikwa uye asingakwanisi kumushambadzi wevatengi. Tarisa mamwe mazano anobatsira usati watenga yako yekutanga video projector .
Mitambo yeVideo Projectors
Kune miviri miviri mikuru yeVideo Projector inowanikwa: DLP ( Digital Light Processing ) uye LCD ( Liquid Crystal Display ). Uyezve, zvimwe zvakasiyana-siyana zveLCD inotaridzirwa nekombiyuta inoshandiswa ndeye LCOS (Liquid Crystal paSilicon), D-ILA (Digital Imaging Light Amplification - yakagadzirwa uye yakashandiswa neJVC) uye SXRD (Silicon Crystal Reflective Display - yakagadzirwa uye inoshandiswa na Sony) . Kuti uwane mamwe mashoko, kusanganisira zvinotsigira nehupenyu hwemarudzi ose, tarisa shamwari yedu nyaya LCD Video Projector Basics .
Mwenje, LED, uye Lasers
Pamusoro pekodzero yeLCD kana DLP iyo inogona kushandiswa muvhidhiyo yeprojekti, chimwe chinhu chingafungidzirwa ndechekuti chiedza chishandiswa chinoshandiswa mumushandisi ndiro mwenje , LED, kana Laser . Zvose zvitatu zvinosarudzwa zvinobatsira uye zvisingabatsiri.
Nzira Dzakanakisisa dzeVideo Projector
Purogiramu yemitambo yemusha yakanakisisa pakuona Mitambo, maDVD, kana mafirimu eBlu-ray. Kana iwe ukatarisa nguva yakawanda TV, LCD / DLP projector inogona kunge iri yakasarudzwa kushandiswa kwevhenekeri yakawanda-based video projector sezvo bhuru (chiedza chine chiedza) chaizoda kuchinjwa mushure memaawa anenge 3 000 kusvika ku4000 ekuona, pamwe chete nemapurojekiti iye zvino ane zvichikwira maawa 5 000 kana kupfuura bhupenyu hupenyu. Enzanisa izvozvo neLCD kana OLED TV iyo inogona kupedza maawa 60 000 kana kupfuura, kunyange zvazvo iri duku rekuyera kwehwindo. Uyewo, iva nechokwadi kuti une nzvimbo yakakodzera yekamuri yeprojekti yako.
Imwe shanduro yakakura yevideo projector ndeyokuona mafirimu kunze kwechando.
Kusarudzwa
Kuchinja kunokosha, kwete kungoita kuti iwe uende kana kufamba neprojekti yako, asi kuita nyore kuisa nekugadzirisa. Izvo zvinoita kuti zvive nyore kuedza zvakasiyana-siyana masikirwo e-screen, kureba, uye makamuri akasiyana kuti aone kuti chii chinoshanda zvakanaka. Kana yako projector ichinyatsogadzirwa iwe unogona kutowira pepa kune rimwe kunze kwemasvingo (kana gonhi regaraji) munguva yezhizha uye unofara iwe pachako-mune mafirimu!
Chiedza Chekujekesa uye Kujeka
Pasina chiedza chakakwana chinobuda, purojekiti haigone kuratidza mufananidzo wakajeka. Kana chiedza chiripo chakanyanyisa chifananidzo chichatarisa dope uye rakanyorova, kunyange muimba yerima. Nzira yakanakisisa yekuona kana purojekiti ichibudisa chiedza chakanaka kuti chibudise mifananidzo yakajeka, chengeta ANSI Lumens rating. Izvi zvichakuudza kuti chiedza chakajeka chinogadzirwa neprojekor. Zvichienderana, zvionekedzo zvine 1 000 ANSI Lumens kana zvakakura zvine ruzivo rwakawanda rwekushandisa imba yemitambo. Kukura kwekamuri, svinga chemahwindo / kure, uye nzvimbo yepamusoro kushamwaridzana kunobatsirawo kuchinja kudiwa kwezvishoma kana zvishoma .
Kusiyanisa Ratio
Kusiyana kwekuenzanisa kunopedza kubwinya. Kusiyanisa ndiko kuenzanisa pakati pepakati uye nyepakati zvikamu zvemufananidzo. High contrast varios inopa vatsvene vatsvene nevatema. Purojekiti inogona kuva neLumens yakawanda, asi kana chiyero chinopesana chiri pasi, mufananidzo wako unotarisa wakashambidzwa. Muimba yakasviba, chiyero chinopesana chinenge 1 500: 1 chakanaka, asi 2,000: 1 kana kupfuura inofungidzirwa zvakanaka.
Pixel Density
Pixel Kusimba kwepamusoro kunokosha. LCD uye DLP veseji vane nhamba yakatarwa yepiksekisi. Kana vakawanda vemaonero ako ari HDTV, svika sepamusoro pepalel count yakawanda sezvinobvira (kunyanya 1920x1080). Nharaunda ye pixel nhamba ye 1024x768 inokwana DVD. Zvisinei, zviratidzo zve 720p HDTV zvinoda 1280x720 pixel kuverengera yekuratidzwa kwekuzvarwa, asi chiratidzo che1080i cheHDTV chinoda chizvarwa che pixel chiverengero che 1920x1080. Kana iwe une Blu-ray Disc player, funga purojekiti ine 1920x1080 yekuzvarwa kwepixel yekugadzirisa uye kukwanisa kuratidza 1080p mafomu.
Mukuwedzera, kana iwe uchida kusvetuka mukati ma 4K, kunze kwemari inowedzera, havasi vese varajeri 4K vanogadzira chisarudzo che 4K chechokwadi. Zvakakosha kuti iwe unzwisise kuti mavhidhiyo e 4K anoshanda sei uye kuti akanyorwa sei kuitira kuti iwe ugone kuita sarudzo yakanaka yekugadzirisa misha yemitambo.
Ratidza Kubudisa
Ruvara Kuberekwa chimwe chimwe chinhu. Chengetedza nyama yepanyama tones uye kupenya kwemavara. Tarisa kuti mavara anotarisa sei munzvimbo dzakajeka uye dzakaoma pane zvemufananidzo. Chengeta uwandu hwemirasi yakagadzikana kubva pane zvaunopinza kusvika kuinyorero, uye kuti iwe unowanzoziva nemhando yezvirongwa zvemufananidzo iyo vhidhiyo yevhidhiyo inopa. Munhu wose ane musiyano mutsva mukuonekwa kwemavara uye izvo zvinotaridzika zvakanaka. Tarisa zvakanaka.
Inputs
Iva nechokwadi chokuti purojekiti ine zvinyorwa zvaunoda. Vhidhiyo yose inojekesa mazuva ano, inopa huwandu hweHDMI , uye akawanda mapurojekiti anewo VGA uye / kana DVI zvinyorwa zvemakombiyuta.
Zvisinei, kana iwe wakwegura pane zvinyorwa izvo zvinoshandisa hukama hwakadai sendimi uye S-vhidhiyo yezvinyorwa zveAnalogog, kana zvikamu zvevhidhiyo zvezvikamu - vazhinji vatsva vhidhiyo vhidhiyo havasati vava kupa izvi zvingasarudzwa kana vanogona kupa mhando yevhidhiyo yakasarudzwa. Saka, apo unotenga purojekiti, zvinonyatsokosha kuti uve nechokwadi chokuti ine hukama hunodikanwa.
Don & # 39; t Kanganwa Screen!
Zvikwangwani zvinouya mumicheka yakasiyana-siyana, ukuru, uye mutengo. Mhando yechinyorwa chakanakisisa chinoenderana nemujekesi, maonero ekuona, chiyero chechiedza chemukati muimba, uye kureba kwepurojekiti kubva pahwindo.
The Bottom Line
Imba yekugadzirwa kwemaimba nevhidhiyo projector iyo iri mukati-kati inogona kunyanya kusimudzira varaidzo yepamba. Zvisinei, haufaniri kusvika muchikwama chako uye nezvimwe zvakasarudzwa kana kuti zvakashandiswa - shandisa mazano akarongwa uye akakurukurwa munyaya ino kukutungamira pakuwana purogiramu yakanakisisa yezvinodiwa zvako.
