I-Epson PowerLite 1975W inxalenye yechungechunge lweprojekthi ye-1900 yenkampani. Lo mgca ujongene namashishini amancinci kunye nabasebenzisi kwimfundo. Le ngenye yezona ndlela eziphezulu kakhulu ezibonakalayo kumgca, ukupakisha kwintlanethi yokungabonakali kwentambo kunye nobuchwepheshe bokuqikelela. Kuyinto, ngokwemvelo, kwakhona phakathi kwendlela ephezulu kakhulu kwi-line.
Ubukhulu
I-Epson PowerLite 1975W iprojekti ye-3LCD. Ilinganiselwa kuma-14,8 intshi ububanzi nge-11,4 intshi ububanzi nge-4.3 intshi ephakamileyo xa inyawo zingakhange ziqwalaselwe, zenze kube mkhulu kunamanqaku afakwe apha ngezantsi kulo mgca.
Ubunzima kwii-10.2 iipounds, okwenza kube nzima kunabanye abaprojekthi.
Bonisa iinkcukacha
Umlinganiselo wendawo yokuzalwa ka-1975W ubhalwe ngo-16:10, oko kuthetha ukuba kulungele ukubukela kwideskrini. Isisombululo sesigqirha siyi-1280 x 800 (i-WXGA), kwaye le nto ingahlaziywa kwi-640 x 480, 800 x 600, 1280 x 1024, kunye ne-1400 x 1050.
Umlinganiselo ochaseneyo kulo mzekelo ngu-10,000: 1.
Ukuphonsa umyinge wezinto ezidweliswe njenge-1.38 (ukusondeza: ububanzi) - 2.28 (ukusondeza: ifoni). I-1975W ingenza iprojekthi ukusuka kumgama wama-intshi ama-30 ukuya kuma-intshi ama-300, efana ne-Power Lite 1955 .
Ukuveliswa kokukhanya kubhalwe kwiimali ezi-5 000 zombala kunye no-5,000 ngokukhanya okumhlophe, okufana nomgangatho ophezulu kulo mgca kwaye ufunyanwe ngowe- 1960 . Umbala kunye nokukhanya okumhlophe kulinganiswa kusetyenziswa ii-IDMS 15.4 kunye nemigangatho ye-ISO 21118, ngokulandelanayo, ngokwe-Epson. Lo ngowomnye umzekelo obalaseleyo wendlela lo mzekelo uhluke ngayo ngo-1945W.
Lo mzekelo usebenzisa isibane esingu-280 W UHE, esinamandla kunezinye izibane kumgca. Inkampani ithi lesi sibane sihlala kwiiyure ezingama-4 000 kwi-ECO Mode kunye ne-3.000 kwiModeli eqhelekileyo (ekupheleni kwayo ephezulu kunabo bonke abanye).
Xa kuthengwa iphrojekithi, isibane sokuphila sisibane kubaluleke kakhulu kuba ukutshintshwa kweso sibane kungabaluleka (akusikho i-bulb light light). Izibane ezitshintshileyo zingasebenzisa i-gamut ngokuxhomekeka kulolu hlobo olufunayo, kodwa lindele ukuchitha i-$ 100- $ 140 enye.
Ubomi bomnxeba buyahlukahluka ngohlobo lweendlela zokubukela ezisetyenzisiweyo kwaye luhlobo luni lokusetyenziselwa. Njengoko inkampani ichaza kwincwadi yayo yemveliso, isibane sokukhanya siza kuhla kwexesha.
IiNkcazo zomsindo
I-PowerLite i-1975W iphakamisa amandla okuphulaphula ngokubonisa omnye wesithethi-16 watt. (Iimodeli ezisezantsi ezantsi kumgca unesithethi se-10-watt.) Oku kufuneka kulungele ukusetyenziswa ngokupheleleyo kwigumbi elikhulu.
Ingxolo yomsindo ingama-31 dB kwimo ye-ECO kunye ne-39 dB kwiMode eqhelekileyo, ngokwe-Epson. Oku kungaphakathi kwinqanaba eliqhelekileyo lemodeli ye-PowerLite yenkampani.
Amandla angenazintambo
Njengo-1945W, i-PowerLite 1975W ibandakanya ukuxhotyiswa kwe-Wi-Fi, kukuvumela ukuba usebenzise ngokupheleleyo i-Epson iProjection app. Le ncedisi ikuvumela ukuba ubonise kwaye ulawule okuqukethwe kwiprojekti yakho usebenzisa i-iPhone, iPad okanye iPod Touch. Umzekelo, ukuba ufuna ukubonisa isithunzi okanye iwebhusayithi kwi-iPhone yakho kwisikrini esicacisiweyo, kufuneka udibanise iprojekti kunye ne-app - ungaze ucinge iingcingo ze USB okanye iintonga ze-USB.
Ukuba awunayo enye yalezi zixhobo ze-Apple, unokulawula kwakhona iphrojekti usebenzisa isiphequluli sekhompyutheni ukuba iphrojekithi ixhunyiwe kwinethiwekhi. U-Epson uthi akukho mfuneko yokukhuphela nayiphi na isofthiwe kwaye isebenza kunye nee-PC nee-Mac.
I-PowerLite 1975W ingasetyenziselwa kunye nezixhobo zokulawula ezikude kunye nezixhobo zolawulo: I-EasyMP Monitor kunye neCrestron RoomView.
I-PowerLite i-1975W inika kwakhona i-wireless projekthi esebenzisa ubuchwepheshe be-Miracast (ngoko unokwenza iprojekthi kwi-smartphones okanye kwiipilisi). Isebenzisa ubuchwepheshe be-WiDi kumadivayisi e-Intel kunye ne-MHL ngokusakaza kunye nokubukraza kwezinye iifowuni ezihambisanayo ze-MHL. (Funda ngaphezulu malunga neMHL apha.)
Iziphumo
Kukho izixhobo ezininzi: I-USB (Uhlobo lwe-A), i-USB (Uhlobo B), Ikhompyutheni 1, ikhompyutha 2, i-HDMI 1 / MHL, i-HDMI 2, iVidiyo, i-Audio kwesokudla kunye nekhohlo, i-Audio 1, i-Audio 2, i-Audio Out, i-Power, i-RS -232c, I-Monitor Out kunye ne-LAN.
Ukuba awuqinisekanga ukuba umehluko phakathi kohlobo lwe-A kunye nohlobo lwe-B b USB, nantsi isifundo esheshayo nesingcolileyo kumbambiswano phakathi kweempembelelo ezimbini: Uhlobo lwe-A libukeka njengomxande kwaye luhlobo oluya kulusebenzisa inkumbulo yememori (ebizwa ngokuba yi-flashable flash drive). Ubume bohlobo B luyahlukahluka, kodwa luhlala lubonakala njengekwere kwaye lusetyenziselwa ukudibanisa ezinye iinkalo zekhompyuter.
Ngenxa yokuba iPowerLite 1975W inomnxibelelisi wohlobo lwe-A, awuyi kucelwa ukuba usebenzise ikhomputha. Ungagcina iifayile zakho kwi-memory stick okanye kwi-hard drive, xhuma kwiprojekti, kwaye uqhubeke.
Amandla
Ukusetyenziswa kwamandla ngo-1975W kubhalwe kuma-435 watts kwindlela eqhelekileyo. Oku kuphakamileyo kunanoma yiphi enye imodeli engezantsi ezantsi kumgca.
Khu seleko
Njengowonke, ukuba akunjalo bonke, iprojekthi ye-Epson, eli liza nechwep yeKenington Safe Lock (isiqhelo esasifumaneka sisetyenziselwa ukusetyenziswa kunye neenkqubo ezixhaswayo zokuvala i-Kensington).
Lens
I-lens ine-zoom zoom. Eli nqaku elivela kwi-About.com ye-Camcorder site ichaza ukungafani phakathi kwezinto ezibonakalayo kunye ne-digital.
Isilinganiselo sokusondeza sibhalwe kwi-1.0 - 1.6. Oku kuyafana nabanye abakweli candelo.
IWaranti
Iwaranti eminyaka emibini engagqithwanga ifakwe kwiprojekti. Isibane singaphantsi kwe-warranty yeentsuku ezingama-90, okuqhelekileyo Iprojekti iphinde ihlanganiswe phantsi kwe-Epson's Road Service Program, ethembisa ukuthumela ubusuku beprojekthi yesikhokelo-ngokukhululekile-ukuba kukho into engalunganga yakho. Ukushicilelwa okulungileyo eceleni, oku kufana nesithembiso esihle kwiimfazwe zendlela. Kukho ukhetho lokuthenga izicwangciso ezongezelelweyo zenkonzo.
Oko Ufumanayo
Kubandakanywe kwibhokisi: iprojekti, i-cable, i-component-to-VGA ikhebula, ukulawula okude kunye neibhetri, isofthiwe kunye ne-CD yomsebenzisi.
Indawo ekude ingasetyenziselwa kude kumgama ongama-26.2 inyawo, ephantse iphindwe kabini umgama wezinye izinto ezihamba phambili kumgca. Iindawo ezikude ziquka imisebenzi elandelayo: Ubumhlophe, ukwahlula, u-tint, u-saturation, ubukhali, uphawu lokufaka, ukuvumelanisa, ukulandelela, isikhundla, ukushisa kombala kunye nevolumu.
I-PowerLite 1975W ibonisa kwakhona isixhobo se-Epson sika-Multi-PC yokuBambisana, ngoko unokubonisa ukuya kwizikrini ezine zekhompyutha ngexesha elifanayo. Izikrini ezingaphezulu zingaphinde zongezwe kwaye zifakwe kwimodi yokulinda.
Le PowerLite 1975W ibonisa ukulungiswa kwelitye lokuzenzekela ngokuzenzekelayo, kunye ne-"Quick Corner" iteknoloji evumela ukuba ulungelelanise nayiphi na ikona yomfanekiso ngokuzimela.
Kwakhona uye wakha kwi-Captioning Closed, kwaye i-Epson ifake ubugcisa obuninzi bokuphucula iikhompyutha ezibhekiselele ekuphuculeni ukusebenza kwevidiyo, njenge-Faroudja DCDi Cinema.
Ixabiso
I-PowerLite 1975W ine-$ 1,999 ye-MSRP.
