TV chophimba kusamvana – kusiyana ndi mmene kusankha zosiyanasiyana

Kusintha kwa TV – ndi chiyani, ndi mitundu yanji yomwe ilipo komanso momwe mungasankhire.

Ndi chiyani, chifukwa chake ndikofunikira kusankha mawonekedwe abwino a TV

Pogula TV, nthawi zambiri amayesa kusankha imodzi yomwe ingapereke khalidwe labwino kwambiri. Komabe, pophunzira zomwe zilipo, wogwiritsa ntchitoyo akukumana ndi kukhalapo kwa mitundu yosiyanasiyana yaukadaulo, yomwe sizovuta kuzizindikira nthawi zonse. Kusintha kwazenera ndi chimodzi mwazinthu zofunika kwambiri posankha zida zapamwamba zapa TV. Kuti mumvetse bwino udindo wake poonetsetsa kuti chiwonetserocho chili bwino, muyenera kumvetsetsa mfundo zomwe ntchito yowonekera imachokera. Zimadziwika kuti mawonekedwe apamwamba, ma pixel ambiri omwe skrini imagwiritsa ntchito.

Ma pixel ndi zinthu, chilichonse chomwe chimapereka chiwonetsero chapamwamba kwambiri pamfundo inayake, palimodzi ndikupanga chithunzi chosintha chowonetsera kanema.

Ma pixel amapangidwa m’mizere ndi mizere. Pofotokoza chilolezo, nambala ya onse awiri imatchulidwa. Kukhalapo kwa zinthu zambiri zoterezi kumapangitsa chithunzicho kukhala chodziwika bwino komanso chapamwamba. Muyeneranso kulabadira kuchuluka ndi mtundu wamitundu yomwe ilipo pa pixel iliyonse. Izi zimadalira osati kuchuluka kokha, komanso teknoloji yomwe imagwiritsidwa ntchito. Ndikofunikiranso momwe chithunzicho chikuwonekera bwino. M’mawonekedwe ena amaperekedwa ndi ma pixel, ena pali wosanjikiza wapadera pa cholinga ichi.
Mapangidwe a ma pixel amadalira ukadaulo wogwiritsidwa ntchito. Nthawi zambiri, amakhala ndi ma subpixels atatu (wobiriwira, buluu ndi ofiira), omwe kuwala kumayikidwa mosiyana. Ubwino wa chithunzi umatsimikiziridwa makamaka ndi mawonekedwe a skrini, komanso zimatengera mawonekedwe ena a TV ndi momwe amawonera. Panthawi imodzimodziyo, mwachitsanzo, amamvetsera kukula kwa diagonal, chiŵerengero cha mawonekedwe a chinsalu, mtunda wa pakati pa owonera ndi chinsalu, ndi zina. https://cxcvb.com/texnika/televizor/vybor-podklyuchenie-i-nastrojka/na-kakoj-vysote-veshat-televizor.html Kachulukidwe ka pixel pa sikweya inchi ndiyofunikira. Mwachitsanzo, kugwiritsa ntchito kusamvana kwa 1920×1080 kudzakhala kosiyana ndi oyang’anira 24″ ndi 27″ chifukwa chakuti mawonekedwe omwe atchulidwa adzakhala osiyana. Muyeneranso kulabadira kuchuluka kwa zotsitsimutsa zenera. Ngati ili yotsika kwambiri, chithunzicho chidzagwedezeka pang’ono, motero zimathandizira kuwonjezeka kwakukulu kwa vuto la maso.

Zimakhulupirira kuti zofunikira zochepa ndi 60 Hz, koma kumbukirani kuti kumtunda kwafupipafupi, chithunzicho chidzakhala bwino.

Muyeneranso kulabadira mtundu wa kusesa ntchito. Mitundu iwiri imagwiritsidwa ntchito kwambiri:

• zolumikizirana;
• wopita patsogolo.

Poyamba, mizere ya ma pixel imasinthidwa poyamba, ndipo mizere yosamvetseka pambuyo pake. Kusintha kwina kwa mizere yofanana ndi yosamvetseka kumayambitsa kunjenjemera, komwe kumayambitsa kutopa kwamaso. Kupititsa patsogolo mizere yonse. M’chaka chachiwiri, kusintha kwazenera kukuchitika bwino. [id id mawu = “attach_10747″ align=”aligncenter” wide=”460″]
Zotsatira za kachulukidwe ka ma pixel osiyanasiyana pamtundu wa chithunzi[/caption] Kukhazikika bwino kumakhudza izi:

1. Amapereka tsatanetsatane wazithunzi . Ndi mawonekedwe apamwamba, owonera amawona chithunzi chowoneka bwino ndipo amatha kuwona mosavuta chilichonse chomwe chimawasangalatsa.
2. Kumasulira kwamitundu yachilengedwe kumakupatsani mwayi wowona bwino zomwe zikuchitika mukamawonera.
3. Kuwala ndi kuya kwa chithunzi kumawonjezera chilengedwe cha chithunzicho.
4. Kupanda kusintha kwakuthwa pakati pa ma pixel ndikofunikira kuti pakhale mawonekedwe apamwamba.
5. Palibe malankhulidwe achilendo kapena zowunikira .

Kuti musankhe mawonekedwe omwe mukufuna, muyenera kudziwa bwino zomwe ma TV akugulitsidwa.

Ndi mitundu yanji ya zisankho zapa TV zomwe ndizodziwika komanso zotchuka

Pali mitundu yambiri ya zowonetsera kutengera kusamvana ndi luso ntchito. Zosankha zodziwika bwino zenera [ caption id = “attachment_10748” align = “aligncenter” wide = “549”]
Zosankha zodziwika bwino za skrini[/caption] Zotsatirazi ndi zosintha zomwe ndizotchuka kwambiri. Pankhaniyi, zizindikiro zawo zazikulu zidzaperekedwa.

Kusintha kwa 640×480

Chigamulochi tsopano chatha. Idagwiritsidwa ntchito pa ma TV oyamba okhala ndi chigamulo cha 4: 3. Pali mitundu iwiri: 640x480i ndi 640x480p. Poyamba, tikukamba za muyezo (SE), chachiwiri – za kuwonjezeka (SD) kumveka. Ngakhale ndizochepa kwambiri, ndizotheka kuwona mumtundu uwu pa TV ndi diagonal yofikira mainchesi 20. Komabe, musayembekezere chithunzi chapamwamba komanso tsatanetsatane wazithunzi zabwino. Mawonekedwe omwe akufunsidwa amagwiritsidwa ntchito makamaka powonera mapulogalamu apawailesi yakanema pawailesi yakanema yapadziko lapansi komanso nthawi zambiri pa digito. Ubwino umakhudzidwa ndi kuchuluka kwa zotsitsimutsa. M’ma TV otere, ndi 30 kapena 60 Hz. Kuipa kogwiritsa ntchito chiganizochi kumawonekera makamaka mukamawona zochitika zothamanga.

HD Yokonzeka

Mtunduwu ndi wa gawo la bajeti. Kusamvana pankhaniyi kudzakhala kofanana ndi 1366×768.
Chiwonetserocho chili mu mawonekedwe a 16: 9. Mukamagwiritsa ntchito zowonetsera zokhala ndi diagonal yopitilira mainchesi 45, zolakwika zazithunzi zimawonekera bwino. Mwachitsanzo, mudzawona kusintha kwamitundu kosagwirizana ndi chilengedwe. Amakhulupirira kuti owonera adzalandira apamwamba kwambiri powonera mapulogalamu pazenera ndi diagonal yofikira mainchesi 25. Komabe, khalidwe limakhalabe lovomerezeka mpaka mainchesi 45. Kugwiritsiridwa ntchito kwa chigamulochi n’koyenera poonera mavidiyo amene akonzedwa kuti asonyezedwe m’njira imeneyi.
