Optoma HD28DSE DLP Projector - Kev Ua Yeeb Yam Ntawm Kev Npaj Tawm Hauv Duab
Lub Optoma HD28DSE yog ib zaug xwb nti DLP video projector uas muaj ib txwm pixel tso saib daws teeb meem ntawm 1920 x 1080 (1080p) , tso zis tso zis, thiab muab cov kev xaiv 2D thiab 3D saib
Yuav kom ntsuam xyuas qhov kev ua yeeb yaj kiab hauv Optoma HD28DSE, kuv siv tus Txheej Txheem Soj Ntsuam (IDT / Qualcomm) HQV DVD Benchmark Disc.
Tus disc muaj ntau cov duab thiab cov duab uas sim yog tias tus yees duab video hauv video projector, TV, Blu-Ray Disc / DVD player, los yog tsev ua yeeb yaj kiab receiver tuaj yeem tso tau tus duab nrog tsawg, los yog tsis muaj artifacts, thaum muaj kev nyuaj siab daws teeb meem los yog tsis zoo los.
Hauv cov kauj ruam ntawm kauj ruam no, cov ntsiab lus ntawm cov kev ntsuam xyuas uas tau teev muaj hauv daim ntawv teev npe saum toj saud yog pom.
Cov kev ntsuam xyuas video hauv qab no rau Optoma HD28DSE Projector tau ua nrog tus neeg siv Oppo DV-980H DVD Player . Cov neeg uas ua ntawv tau teem rau NTSC 480i daws teeb meem thiab txuas nrog HD28DSE ntawm qhov kev sib txuas ntawm HDMI (HD28DSE tsis muaj Composite Video , S-Video , los yog Component Video inputs), yog li ntawd cov qhab nia xeem tau pom txog kev ua tiav video ntawm HD28DSE. Cov qhab-nees raug kuaj pom tau raws li ntsuas los ntawm Silicon Optix (IDT / Qualcomm) HQV DVD Benchmark Disc.
Cov kev ntsuas siab ntxiv thiab 3D kev ntsuam xyuas tau siv ua Oppo BDP-103 Blu-Ray Disc neeg ua si nrog cov HVQ HD HQV Benchmark thiab Spears thiab Munsil HD Benchmark 3D Disc 2nd Edition test discs.
Tag nrho cov kev ntsuam xyuas tau siv lub HD28DSE lub chaw tso cai siv default - thiab nrog nws cov kev cai Darbee Visual Presence muab tua.
Screenshots hauv no gallery tau muab siv Sony DSC-R1 Still Camera.

Optoma HD28DSE DLP Video Projector - HD Resolution Loss Test
Hauv qhov kev ntsuam xyuas no, daim duab tau raug kaw hauv 1080i (ntawm Blu-Ray), uas Optoma HD28DSE Projector yuav tsum tau reprocess li 1080p . Ua qhov kev xeem no, Blu-Ray tshooj Disc li tso rau hauv OPPO BDP-103 Blu-Ray Disc Player uas tau teem rau 1080i tso zis thiab txuas nrog ncaj qha mus rau HD28DSE ntawm kev sib txuas ntawm HDMI.
Qhov kev tawm tsam rau HD28DSE yog tias nws yuav tsum pom ob qhov tseem thiab tsiv ntawm daim duab thiab tso cov duab hauv 1080p tsis muaj suab nrov los yog suab paj nruag artifacts. Yog hais tias tus processor tsim kom zoo, lub tsiv bar yuav ua tus du thiab tag nrho cov kab hauv ib qho tseem ntawm daim duab yuav pom txhua lub sijhawm.
Yuav ua kom txoj kev xeem tsis yooj yim dua, cov plaub fab ntawm txhua lub ces kaum muaj cov kab dawb ntawm khib thav ntawv thiab cov kab dub rau ntawm cov thav ntawv. Yog hais tias tus squares tsis tu ncua qhia tseem kab qhov processor yog ua tiav ib txoj haujlwm tiav ntawm reproducing tag nrho cov kev daws teeb meem ntawm thawj daim duab. Txawm li cas los xij, yog cov square blocks pom los ntawm cov vib thab los sis txoj hlua khau dub (piv txwv) thiab dawb (piv txwv), ces tus yees duab ua haujlwm tsis pom cov teeb meem ntawm tag nrho cov duab.
Raws li koj tuaj yeem pom hauv kablus no, qhov chaw hauv cov ces kaum pom cov kab tseem tseem. Qhov no txhais tau hais tias cov plaub fab no tau muab tso tawm kom zoo li lawv tsis qhia txog cov khoom dawb los yog dub dub, tab sis ib lub voj voos uas muaj cov kab sib txuas. Tsis tas li ntawd, lub khawm qhov cub kuj tseem heev.
Cov kev tshwm sim qhia tau hais tias Optoma HD28DSE Projector zoo sib deinterlacing 1080i rau 1080p nrog regards rau ob leeg tseem keeb thiab tsiv khoom, txawm tias cov ntsiab yog chav nyob rau hauv tib lub thav duab los yog txiav.
