Nhasi, iyi chiyero ndeimwe yeanowanzo sangana uye anotengwa. Muindasitiri yemafirimu, inodaidzwa kuti 4K nekuti furemu hupamhi hwefuremu hwave 4000 pixels. Zvinofadza kuti vagadziri veterevhizheni havafungi kugumira ipapo. Kuti unzwisise vhidhiyo yekutsanangura-yepamusoro-soro, unofanirwa kufungidzira skrini yemamita gumi nemashanu. Mufananidzo uri pairi ucharamba uine kujeka kwakafanana sepaterevhizheni yakajairwa. Iyo digital cinema projekta inongotsigira 2k resolution. Tsigiro yefomati yequad iri paIMAX. Yakaturikirwa kubva muChirungu chekushambadzira, iyi ndiyo mhando yepamusoro yemufananidzo. Kune iyo chiyero, akati wandei mapurojekita ane kane resolution anoshandiswa. 4k inoreva kujeka kwakakwana uye ruzivo rwechifananidzo, chinofambiswa zvakajeka uye chakazara. Density ine realism yemufananidzo inokura nekuda kwekuderedzwa kwepixel saizi uye kuwedzera kwenhamba yavo. Nekuda kweizvozvo, zvinhu zvinowedzera kutsanangurwa muhurongwa uye zvinogona kutariswa zvirinani. Kuenzaniswa ne2k, 4k inopa yakagadziridzwa furemu chiyero, kudzika kwemavara uye kunaka kwenzwi. UHD inoshandisa furemu chiyero. Muvara une hudzamu hwemabhiti gumi nemaviri, uye kuvhara kwemavara i75%. Iyo skrini inoburitsa anenge 69,000,000,000 mimvuri yeruvara palette. Kuti unzwisise zviri nani, iyo yepamusoro-yekupedzisira Full HD modhi inoshandura mafuremu nekumhanya kwe60 kiloseconds. Rudzi i8 bits, uye nzvimbo yemavara inovhara skrini ne35%.

Musiyano pakati pe4K uye 2K resolution

HDTVs anga ari chiyero chakashandiswa kwemakumi emakore. Nhasi, hapana michina yeterevhizheni isingaratidzi 720p resolution. “P” inomirira rudzi rwemufananidzo unoenderera mberi. Ini ndini imwe nzira, inotaridzwa yakabatanidzwa. Mitsetse isinganzwisisike uye yakatodzana inoratidzwa zvakachinjana mune imwe neimwe furemu. Izvi zvinoguma nekudzikira kwemhando yemufananidzo. Izwi rekuti 4000 pixels iratidziro fomati ine yakafara yakachinjika resolution. UHD i4k. Musiyano ndewekuti wakanyatsokodzera vatengi uye terevhizheni ine 2k.

Zvakanakira nekuipira kwe4k resolution kana ichishandiswa paTV

4k resolution inopa yakanyanya-yakajeka yemifananidzo ruzivo nekuwedzera pixel density pascreen square millimeter. Muyero wekutsvaira ndeye 120 mafuremu pasekondi. Mufananidzo wakasimba wakadaro unopa kushushikana kudiki pameso, kunyanya kana munhu achiona terevhizheni kwenguva yakareba uye neawa. 4k resolution inoburitsa yakadzika, akapfuma mavara. Iyo inosimudzira kujeka kwemufananidzo munzvimbo mbiri dzakajeka uye dzakasviba dzechidzitiro. Iyo fomati inopa yakanakisa ruzha mhando. Iyo isina mubvunzo mushandisi mukana we Ultra HD TVs ndeaya anotevera chokwadi:

1. Iyo fomati inogona kushandiswa kune widescreen vhidhiyo mitambo, komputa matrices; Iyo skrini inonyudza iwe muchokwadi chaicho pasina akakosha magirazi.
2. Iyo matrix inoumba matatu-dimensional mhando yemufananidzo iyo muoni anoongorora kubva chero nguva; zvestereo haudi magirazi.
3. TV inogona kutariswa iri chinhambwe chipfupi, izvi zvinokonzerwa nekuwedzera kwechina mumufananidzo wescreen.

Iyo mukana inguva yekugona kwekuisa TV mufurati diki ine nzvimbo ine mwero yemakamuri.

Iko kusakosha kukuru kwe4k kugadziriswa ndiko kuwedzera kudiwa kwehutano hwechiratidzo. Izvi zvinotungamirira kune zvishoma zvinyorwa zvinoparidzirwa muhutano hunoshandiswa. Kune akakosha mafirimu uye anoratidza paYouTube anogona kushandiswa pamhando dze4k. PaNetflix pane mafirimu ane akatevedzana ane inobhadharwa, inodhura kunyoreswa. Megogo ine yakawanda-yepamusoro-tsanangudzo yemukati.

Ndeapi maTV anoshandisa 4k
