Ndi kukonzanso kwamasewera osangalatsa apanyumba, msika wanzeru wowonera udayambitsa nthawi yophulika, ndipo ogwiritsa ntchito ambiri alinso ndi chidwi chofuna kudziwa zamitundu yatsopano monga zinthu zongoyerekeza.Ndiye, timasankha bwanji mapurojekitala?
Native Resolution
Ziribe kanthu kuti ndi chida chanji cha digito, kuthetsa ndi chinthu chodetsa nkhawa kwa aliyense.Malingaliro odziwika bwino ndi njira zoyimira ndi izi:
SVGA: 800x600 purojekitala yachuma yogwirizana
XGA: 1024x768 resolution yotengedwa ndi ma projekitala apakatikati abizinesi ndi maphunziro
SXGA+: 1400x1050 resolution yotengedwa ndi mapurojekitala apamwamba kwambiri pamapulogalamu apamwamba kwambiri monga zithunzi
480p: Chisankho chomwe chimagwiritsidwa ntchito ndi ma projekiti apanyumba a 852x480 otsika
720p: 1280x720 kapena 1280x768 malingaliro ogwiritsidwa ntchito ndi ma projekiti apanyumba apakatikati
1080p: 1920x1080 kapena 1920x1200 chisankho chotengedwa ndi mapurojekitala apanyumba apamwamba kwambiri.
Moyo Wautumiki
Chida chilichonse cha digito chimakhala ndi moyo wantchito.Zida zama digito zogulidwa pamtengo wokwera ziyenera kukhala zolimba.Kwa projekiti, malo omwe amatayika kwambiri ndi babu wamkati.Moyo wa purojekitala wamba ndi pafupifupi zaka zinayi, ndipo babu yomangidwamo nthawi zambiri imayenera kusinthidwa pakadutsa zaka ziwiri.Ngakhale pambuyo m'malo, zotsatira zam'mbuyo sizidzatheka.Chifukwa chake, pogula purojekitala, tikulimbikitsidwa kuti mupereke patsogolo kukhazikika komanso komveka bwino kwa gwero la kuwala kwa LED.
Kuwala
Kuwala kwa projector ndi lingaliro lomwe liyenera kutchulidwa potchula pulojekitiyo.Lumen ndi gawo lomwe limafotokoza kuwala.Fanizo losavuta kwambiri: Zimatsimikizira ngati mutha kuwona mithunzi kapena kuwona mtambo wa kuwala koyera mukamawonera kanema masana.
Lumen 500 imatha kuwonedwa mumdima.Ma Lumens ali mumtundu wa 1000-2000, ndipo makatani amakokedwa masana, ndipo palibe kusonkhezera kwamphamvu kwa kuwala, ndipo kumatha kuwonedwa bwino.Pamene lumens ili pamwamba pa 2000-3000, imakhala yowala mokwanira, ndipo makamaka mfundo zina zomwe zimakhudza maonekedwe.Ndikofunikira kusankha purojekitala yokhala ndi ma lumens pafupifupi 2000 kuti mugwiritse ntchito mchipinda chogona, ndi purojekitala yopitilira 2000 yogwiritsidwa ntchito m'malo akulu monga pabalaza.
Mawu ndi Kuziziritsa
Ma projekiti apamwamba kwambiri nthawi zambiri amakhala ndi ntchito zabwino kwambiri zochotsera kutentha, pomwe kusiyana kwakukulu pakati pa ma projekita otsika ndi ma projekiti odziwika ndi ntchito yochotsa kutentha ndi phokoso.Ma projekiti omwe ali ndi ntchito yabwino kwambiri yochepetsera kutentha nthawi zambiri amagwiritsa ntchito phokoso lotsika kwambiri, ndipo kuchuluka kwa phokoso ndikofunikira kwambiri pakuwonera kwa wogwiritsa ntchito.Phokoso loyambira ≤40DB ndilobwino kale, ndipo limatha kupereka malo owonera mwakachetechete.
