I-Epson PowerLite 1980WU iyingxenye yochungechunge lweprojekthi ye-1900 yenkampani. Njengamanye amamodeli emgqeni, le projekthi ihloselwe amabhizinisi amancane nabasebenzisi emfundweni. Lokhu kungenye yezithombe ezibiza kakhulu zezinhlobo ezingu-1900, kodwa akuyona into ephezulu yomugqa.
Ubukhulu
I-Epson PowerLite 1980WU iphrojekthi ye-3LCD. Isilinganiso esingu-14,8 amasentimitha ububanzi ngo-11.4 amasentimitha ububanzi ngamasentimitha angu-4,3 phezulu lapho izinyawo zingacatshangwa. Kuhlanganisa izinyawo ezihamba nge-0.6 intshi eyengeziwe ngaphezu kokuphakama.
Ilinganisa ngamapounds angu-10.2, okusho ukuthi ithwala ubukhulu obufanayo njenge- PowerLite 1975W .
Bonisa ama-Specs
Isilinganiso sesibalo se-1980WU sibhalwe ngo-16:10, okusho ukuthi kulungile ukubukwa kwesikrini. Isixazululo somdabu singu-1280 x 1200 (WUXGA), futhi lokhu kungasuswa kabusha ku-640 x 480, 800 x 600, 1280 x 1024, no-1400 x 1050. Unomqondo ophezulu wesintu kunama-1975W.
Isilinganiso esiphathelene nalesi simodeli ngu-10,000: 1 (esifana ne-1975W).
Ububanzi bokulinganisa ububanzi bubalwa njengo-1.38 (ukusondeza: ububanzi) - 2.28 (ukusondeza: ucingo). I-1980WU ingayenza ibanga elingama-intshi angu-30 kuya kwamasentimitha angu-300, okufana nango-1975 kanye ne-Power Lite 1955 .
Ukukhishwa okukhanyayo kubhalwe ku-4,400 izibani zombala nombili ukukhanya okumhlophe. Lokhu kuphansi kunalokho okushiwo yi-1975W - okungu-5,000 ngombala nomhlophe - futhi kungasiza ukuchaza ukwehla kwentengo. Umbala nokukhanya okumhlophe kulinganiswa ngokusebenzisa ama-IDMS 15.4 namazinga we-ISO 21118, ngokulandelana, ngokwe-Epson.
Lo modeli usebenzisa isibani esingu-280 W UHE, esinamandla kunamanye amanye izibani emgqeni. Le nkampani ithi lesi sibani sihlala emahoreni angu-4,000 ku-ECO Mode kanye no-3000 ku-Mode Normal. Lesi yisibani esifanayo ne-1975W.
Uma uthenga iprojekti, isikhathi sokuphila kwesibani siyinto ephawulekayo ngoba ukufaka isibani kungaba yindleko (lokhu akuyona isibani esivamile). Izibani ezishintshayo zingasebenzisa i-gamut kuye ngokuthi uhlobo oludingayo, kodwa lindele ukuchitha u-$ 100 ukuya ku-$ 140 ngenye.
Ukuphila kwamangqamuzana nakho kungashintsha ngokususelwa kuhlobo lokubuka izindlela ezisetshenzisiwe nokuthi yiluphi uhlobo lokusetha olusetshenzisiwe. Njengoba inkampani ibhekisela ezincwadini zayo zomkhiqizo, ukukhanya kwebani kuzokwehla ngokuhamba kwesikhathi.
Izinkomba zomsindo
Njengombutho we-PowerLite 1975W, i-1980WU ithuthukisa amandla okulalelwayo ngokumelene namamodeli we-step-down emgqeni ngokwakha esitatimendeni esisodwa se-16-watt. (Lezo zithombisi ezisezingeni eliphansi ngalinye zinezikhulumi ezingu-10-watt.) Lokhu kumele kusetshenziswe ngokuphelele ekamelweni elikhulu.
Umsindo womculo u-31 dB ku-ECO Mode kanye no-39 dB ku-Mode Normal, ngokusho kwe-Epson. Lokhu kungaphakathi kwebanga elijwayelekile lamamodeli we-PowerLite yenkampani.
Amandla angenantambo
Ngokungafani no-1975W, noma kunjalo, i-PowerLite ayifaki ukukwazi ukungena ngaphakathi kwe-Wi-Fi. Ukuze usebenzise insiza ye-Epson iProjection, kufanele uthenge umthamo we-LAN wangaphandle. Insiza ye-iProjection ikuvumela ukuba ubonise futhi ulawule okuqukethwe kusuka kwiprojekitha yakho usebenzisa i-iPhone, iPad noma i-iPod Touch. Isibonelo, uma ufuna ukukhombisa isithombe noma iwebhusayithi ku-iPhone yakho kwisikrini sokubukwa, udinga ukumbhangqa iphrojekitha ngohlelo lokusebenza - ungalokothi ucabangele izintambo ze-USB noma izinti ze-USB.
Uma uthenga umthamo we-LAN, ungaphinde ulawule iphrojekitha usebenzisa isiphequluli sekhompyutheni uma iprojekthi ixhunyiwe kwinethiwekhi. I-Epson ithi akudingeki ukulanda noma iyiphi isofthiwe futhi isebenza nama-PC nama-Mac.
Nakuba ingenayo i-Wi-Fi eyakhelwe ngaphakathi (enye insiza ekunciphiseni kwentengo), i-PowerLite 1980WU inika amandla ukusakaza okungenawaya nokubuyisa nge-MHL kusuka kwamanye amadivayisi ahambisanayo ne-MHL. (Funda kabanzi mayelana ne- MHL lapha.)
I-PowerLite 1980WU ingasetshenziswa futhi ngamathuluzi okulawula nokulawula okude okulandelayo: I-EasyMP Monitor neCrestron RoomView.
Imigomo
Kukhona izimpendulo eziningi: i-USB (Thayipha A), i-USB (Thayipha B), ikhompyutha 1, ikhompyutha 2, i-HDMI 1 / MHL, i-HDMI 2, iVidiyo, i-Audio kwesokudla nokunxele, i-Audio 1, i-Audio 2, i-Audio, i-Power, i-RS -232c, i-Monitor Out ne-LAN.
Uma ungaqiniseki umehluko phakathi kohlobo lwe-Type A nohlobo lwe-USB B, nasi isifundo esisheshayo nesingcolile umahluko phakathi kwezimpendulo ezimbili: Uhlobo A lubukeka njengetrange futhi luhlobo oluzosebenzisa inkumbulo yememori (ebizwa nangokuthi i-portable flash drive). Ukuma kohlobo B kungashintsha, kodwa ngokuvamile kubonakala njengesikwele futhi kusetshenziselwa ukuxhuma ezinye izithako zekhompyutha.
Ngenxa yokuthi i-PowerLite ye-1980WU inomculi wohlobo lwe-A, ngeke kudingeke ukuthi usebenzise ikhompuyutha ukuze uvezwe. Ungagcina amafayela akho kumemori ye-memory noma i-hard drive, ukuxhuma kumprojekti, futhi uqhubeke.
Amandla
Ukusetshenziswa kwamandla we-1980WU kubhalwe kuma-watts angu-409 ku-Mode Normal nama-watt angu-330 ku-Eco Mode. Lokhu kuncane kakhulu kune-PowerLite 1975W.
Ukuphepha
Njengabaningi, uma kungenjalo bonke, abaprojekthi be-Epson, leli liza nechweba likaKensington's Security Lock (indawo evame ukutholakala ekusetshenzisweni nezinhlelo ezithandwayo zokukhiya).
I-lens
I-lens ine-zoom yokukhanya. Lesi sihloko esivela ku-website ye-About.com sika-Camcorder ichaza umehluko phakathi kwama-optical optical ne-digital.
Isilinganiso sokusondeza sibhalwe ku-1.0 - 1.6. Lokhu kufana nalabanye abakulesi sigaba.
Iwaranti
Iwaranti enomkhawulo weminyaka emibili ifakiwe kumprojekti. Isibani singaphansi kwewaranti yosuku lwezinsuku ezingu-90, okuyinto ejwayelekile Iprojekti iphinde ihlanganiswe ngaphansi kohlelo lwe-Epson's Road Service, oluthembisa ukuthumela ubusuku obunamaprojekti esikhundleni sendawo - mahhala - uma kukhona okungalungile ngeyakho. Ukuphrinta okuhle eceleni, lokhu kuzwakalisa isithembiso esihle sabasemgwaqweni. Kukhona ukhetho lokuthenga izinhlelo ezengeziwe zesevisi enwetshiwe.
Okutholako
Kufakwe ebhokisini: iprojekti, ikhebula lamandla, ikhebula le-VGA, i-remote control kanye namabhethri, ama-software kanye nama-CD omsebenzisi omsebenzisi.
Indawo eyikude ingahle isetshenziswe kude kumamitha angaba ngu-26.2, okucishe ibe kabili ibanga lamanye ama-remotes emgqeni. (Ihambisana nendawo eyikude ehlanganiswe ne-1975W.) Okukude kufaka phakathi imisebenzi elandelayo: Ukukhanya, ukuphambene, ukugubha, ukugcwalisa, ubukhali, isignali yokufaka, ukuvumelanisa, ukulandelela, isikhundla, ukushisa kombala kanye nevolumu.
I-PowerLite ye-1980WU iphinde ihlanganise ithuluzi le-Epson's Multi-PC Ukusebenzisana, ukuze ukwazi ukubonisa izikrini ezine zekhompyutha ngesikhathi esifanayo. Izikrini eziningi zingabuye zengezwe bese zifakwa esimweni sokulinda.
Le phrojekthi iphinde ilungiselelwe ukulungiswa okuyi-automatic keystone, kanye nobuchwepheshe bokuthi "Quick Corner" okukuvumela ukuba ulungise noma yikuphi ukona wesithombe ngokuzimela.
Okokugcina, kuhambisana nokwaziswa okuvaliwe okuvaliwe, futhi i-Epson ifake ubuchwepheshe obuningi bokuthuthukiswa kwevidiyo okuhloswe ukuthuthukisa ukusebenza kwevidiyo, njenge-Faroudja DCDi Cinema.
Intengo
I-PowerLite 1980WU ine-$ 1,499 ye-MSRP, eyi-$ 500 engabizi ngaphezu kuka-1975W. Uma udinga i-Wi-Fi yokusakaza okungenantambo, qiniseka ukuthi ubheka izindleko ezengeziwe ze-LAN module yangaphandle.
