Ichi ndi chimodzi mwa zitsanzo zapamwamba kwambiri pa mzere, ponyamula mumasewera ambirimbiri osakanikirana ndi mafilimu. Ndi, mwachibadwa, komanso pakati pa mtengo wapamwamba kwambiri mu mzere.
Miyeso
Epson PowerLite 1975W ndi 3LCD projector. Maseŵerawa amayenda masentimita 14,8 m'lifupi ndi 11.4 mainchesi mwake ndi masentimita 4,3 pamwamba pamene mapazi saganiziridwa, kuzipanga kukhala zazikulu kwambiri kuposa zitsanzo zomwe zili pansipa pamzerewu.
Imakhala yolemera pa mapaundi 10.2, ndipo imapangitsa kuti ikhale yolemerera kuposa mapulojekiti ena.
Onetsani Mafotokozedwe
Chiwerengero cha chigawo cha 1975W chalembedwa pa 16:10, chomwe chikutanthauza kuti ndizoyenera kuyang'ana pawindo. Chigamulocho ndi 1280 x 800 (WXGA), ndipo izi zikhoza kusinthidwa ku 640 x 480, 800 x 600, 1280 x 1024, ndi 1400 x 1050.
Chiwerengero chosiyana cha chitsanzo ichi ndi 10,000: 1.
Zowonetsera chiwerengerocho ndi 1.38 (zojambula: lonse) - 2.28 (zojambula: tele). Mchaka cha 1975W akhoza kupanga kuchokera pamtunda wa masentimita 30 kufika masentimita 300, zomwe ziri chimodzimodzi ndi Power Lite 1955 .
Kuwunika kwa kuwala kumatulutsidwa ku lumens 5,000 kwa mtundu ndi 5,000 ku kuwala koyera, komwe kumakhala kwakukulu kwambiri mu mzerewu ndipo kumapezeka pafupifupi mu 1960 . Kuwala ndi kuwala kumayesedwa pogwiritsira ntchito IDMS 15.4 ndi miyezo ya ISO 21118, motsatira, malinga ndi Epson. Ichi ndi chitsanzo china chofunika kwambiri cha momwe chitsanzochi chikusiyana ndi 1945W.
Chitsanzochi chimagwiritsa ntchito nyali 280 WHEHE, yomwe imakhala yamphamvu kwambiri kuposa nyali zina mumzerewu. Kampaniyo imati nyali iyi imatha maola 4,000 mu ECO Mode ndi 3.000 mu Machitidwe Ochizolowezi (omwe amathawo ndi omwe ali apamwamba kuposa enawo mafano).
Pogula projector, nthawi ya moyo wa nyali ndi yofunika kwambiri chifukwa kukhala m'malo mwa nyali kungakhale kovuta (iyi si babu wamba). Mafuta omwe amatha kusintha akhoza kuyendetsa masewerawa malinga ndi mtundu womwe mukufunikira, koma yang'anani kuti muzikhala pafupi $ 100- $ 140 pa imodzi.
Moyo wa nyali ungasinthenso mosiyana ndi mtundu wa njira zowonera zomwe zikugwiritsidwa ntchito ndi mtundu wanji wazogwiritsiridwa ntchito. Monga momwe kampani ikusonyezera mu zolemba zake zopangidwa, kuwala kwa nyali kudzachepa pakapita nthawi.
Nkhani Zomveka
PowerLite 1975W imakweza zojambulazo pogwiritsa ntchito wolankhula 16-watt. (Zithunzi zowonongeka pamzerezi zili ndi wolankhula 10-watt.) Izi ziyenera kukhala zoyenera kugwiritsa ntchito m'chipinda chachikulu.
Phokoso la fan ndi 31 dB mu ECO Mode ndi 39 dB mu Machitidwe Ochizolowezi, malinga ndi Epson. Izi ndizomwe zili muzithunzi za PowerLite za kampani.
Zosayenerera opanda waya
Monga 1945W, 1975W PowerLite imakhala ndi Wi-Fi yokhazikika, yomwe imakupatsani mwayi wopindula ndi Epson's iProjection app. Mapulogalamuwa amakulolani kusonyeza ndi kuyendetsa zinthu kuchokera pulojekiti yanu pogwiritsa ntchito iPhone, iPad kapena iPod Touch.

Ngati mulibe zipangizo zamapulogalamu awa, mukhoza kuyang'anira pulojekitiyo pogwiritsa ntchito osuta makompyuta ngati pulojekiti ikugwirizanitsidwa ndi intaneti. Epson akuti simukufunikira kukopera pulogalamu iliyonse ndipo imagwira ntchito ndi ma PC ndi Mac.
PowerLite 1975W ingagwiritsidwenso ntchito ndi zipangizo zotsatirazi: • EasyMP Monitor ndi Crestron RoomView.
PowerLite 1975W imathandizanso kugwiritsa ntchito zipangizo zamakina zamagetsi (kotero kuti mutha kugwiritsa ntchito mafoni kapena mapiritsi). Ikugwiritsanso ntchito teknoloji ya WiDi kwa Intel zipangizo komanso MHL kusakanikirana ndi kuyang'ana kuchokera ku zipangizo zina zogwirizana ndi MHL. (Werengani zambiri za MHL kuno.)
Zotsatira
Pali njira zambiri: USB (Mtundu A), USB (Mtundu B), Makompyuta 1, Makompyuta 2, HDMI 1 / MHL, HDMI 2, Video, Audio kumanja ndi kumanzere, Audio 1, Audio 2, Kutulutsa Audio, Mphamvu, RS -232c, Yang'anani kunja ndi LAN.
Ngati simukudziwa bwino kusiyana kwa mtundu wa mtundu A ndi mtundu wa B B, apa pali phunziro lachidule komanso loipa pa kusiyana pakati pa zigawo ziwiri: Mtundu wa A umawoneka ngati rectangle ndipo ndiwo mtundu umene muti mugwiritse ntchito ndi chikumbutso cha kukumbukira (chomwechonso chimatchedwa flash portable drive). Mapangidwe a mtundu B akhoza kusiyana, koma nthawi zambiri amawoneka ngati malo amodzi ndipo amagwiritsidwa ntchito polumikiza zipangizo zina zamakompyuta.
Chifukwa chakuti PowerLite 1975W ili ndi mtundu wa mawonekedwe A A, simudzasowa kugwiritsa ntchito makompyuta. Mukhoza kusunga mafayilo anu pamtundu wa memory kapena hard drive, kulumikiza ku projector, ndi kupitiriza.
Mphamvu
Kugwiritsira ntchito mphamvu kwa 1975W kunalembedwa pa 435 Watts mu Machitidwe Ochizolowezi. Izi ndizitali kuposa zitsanzo zina zonse zotsatila mzere.
Chitetezo
Monga ambiri, ngati si onse, opanga Epson, awa amabwera ndi doko la Kensington la Security Lock (malo omwe amapezeka kuti agwiritsidwe ntchito ndi machitidwe otchuka a Kensington).
