Ndeipi TV iri nani kutenga - 4K kana FullHD

Nekuda kwekuwanda kwezvipo pamusika weSmart TV, mubvunzo wekusarudza michina pakati pe4K uye FullHD iri kubvunzwa zvakanyanya uye kazhinji. Kunyangwe 2-3 makore apfuura, kumhanyisa-mumutengo kwaive kwakakura - 50-100%. Asi nekuda kwekudiwa kwe4K TVs, mutengo wakadzikira zvakanyanya mushure mekunge mabhureki mazhinji apinda mumusika. Uye musiyano mumutengo hausisiri kuoneka - 15-30%. Naizvozvo, kune mimwe mibvunzo - ndeipi TV iri nani kutenga - 4K kana FullHD.

 

Isu tisingabatanidzi kushambadzira - isu tinotarisa tekinoroji maitiro

Icho chiripo ndechekuti vese vanogadzira vanofarira kutengesa zvinhu zvinodhura. Uye zvigadziriso zvisingadhuri zvinonangana nechikamu chebhajeti. Iwe haugone kungoivhara, nekuti panogara paine mutengi ane mari shoma. Saka achatenga izvo zvisingadhuri, asi TV yakanaka kudaro. Naizvozvo, muzvikamu zvese zvemitengo, isu tinopihwa akati wandei mhinduro kamwechete kuitira kufambisa kutsvaga pane bhajeti.

 

4K TV kana FullHD - zviri nani

 

Zviri nani apo TV inobereka mavara chaiwo. Uye hazvina basa kuti ine resolution ipi. Mushure mezvose, kufarira kwemutengi kuwana mufananidzo wakanaka pachiratidziri. Resolution ndiyo yechipiri criterion pano, iyo inotsamira pane akati wandei zvinhu kamwechete:

 

• Diagonal size. 4K ndeye 4096x3072 dots paskweya inch. Uyu ndiwo chiyero. Uye maTV ane resolution ye1 × 3840. FullHD ndeye 2160-1920 dots paskweya inch. Uye kune maTV ane diagonal hombe (kubva pa1080 kusvika 55 inches), mapixels ari paFullHD matrix achave akakura kupfuura pa80K matrix. Ndiko kuti, hapana chikonzero chekutenga 4K TV ine resolution isingasviki 4 inches. Iyi imari inodzika pasi.

• TV processor performance. Vese vagadziri, vachisimudzira tekinoroji yavo, vanoramba vakanyarara kuti iyo yakavakirwa-mukati decoder haigari yakagadzirira kugadzirisa chiratidzo che4K nenzira kwayo. Kuti uwane mufananidzo wemhando yepamusoro, inoridza midhiya (TV-BOX) inodiwa. Uye muFullHD, zvese zvinoshanda zvakanaka pane chero TV.
• Iko kugona kwematrix kushanda nemavara shades. Pane mapaneru akachipa, kunyangwe mu4K resolution, mushandisi haaone yaunoda mhando. Uye pazviratidziro zvinodhura, iyo FullHD fomati inogona kuburitsa mamwe echokwadi mifananidzo.
• Content. Sezvingatarisirwa, 4K TV inoda yakakodzera sosi. Zvekare, iyi inoridza midhiya kana YouTube vhidhiyo. Mazhinji emafirimu nemavhidhiyo (uye izvi zvinopfuura makumi mapfumbamwe) zviri muHD kana FullHD. Kana mushandisi asiri kuzotenga Blue-Ray discs kana kurodha mabhaisikopo ku90K, saka zvine musoro kubhadhara zvakanyanya kuita uku.

 

Ndeipi TV iri nani kutenga - 4K kana FullHD

 

Saka, takasarudza pamateki ekutengesa. Ino ndiyo nguva yekubata pane akakosha uye anobatsira matekinoroji ayo anopa mushandisi mhando yekufambisa kwevhidhiyo.

 

• HDR 10 (High Dynamic Range) iratidziro yevhidhiyo ine kudzika kwemavara epamusoro. Izvi zvinoreva, kuwedzera kwemavara emavara, ayo akaumbwa nemuiti wefirimu. 10 bits inotipa 1 bhiriyoni shades. Uye 8 bits inotipa mamirioni gumi nematanhatu mimvuri. Zvinonyanya kukosha, nokuda kwechokwadi, kutenga TV ine HDR Muchikamu chebhajeti, pasi peHDR 16 yekumaka, isu tiri 10% yakapiwa 100 + 8FRC. Aya maviri FRCs imhando yehunyengeri, iyo kubva pamamiriyoni gumi nematanhatu mimvuri inoita anti-aliasing pakati pepixels.
• LED uye QLED (OLED). MaTV ane QLED matrix anoratidza mufananidzo unooneka. Asi ivo vanodhura 1.5-2 nguva yakawanda. Quantum dot tekinoroji inobvumidza iwe kutamisa mimvuri nenzira yakarongwa nemunyori wevhidhiyo. Uye LED isoftware chiratidzo chekugadzirisa nekugadzirisa kune yaunoda mhando.

Padanho rekusarudza pakati pemutengo uye hutano, hapana kukanganisa kunogona kuwanikwa. Humwe hunhu, asi hunodhura, kana mutengo wakakwana, asi pamutengo wemhando yepamusoro kubereka kwemavara. Uye iwe unofanirwa kuzvisarudzira iwe usati waenda kuchitoro.

 

Nzira yekusarudza TV muchitoro - mutungamiri wekutanga

 

Isu takasarudza kutenga TV ine diagonal hombe uye yakachipa - tora chero ine saizi inosvika makumi matanhatu inches FullHD. Zvirinani kutarisa mucherechedzo. Semuenzaniso, Samsung, LG kana Philips ichagara makore gumi uye ichakufadza iwe nemufananidzo weruvara. Pasinei teknolojia. Zvigadzirwa kubva kuChinese vagadziri (KIVI uye Xiaomi zvechokwadi) vane makore 60-10 uye matrix inoda kuchinjwa.

Kana iwe uchida kuwana mufananidzo wemhando yepamusoro - sarudza maTV kubva pa55 inches ane 4K resolution uye HDR10. Zviri nani neQLED matrix. Uye zvechokwadi, chete mazita enyika ane mukurumbira Sony, Samsung, LG. Zvinodhura. Asi kushandurwa kwemavara kuchave kunoshamisa uye kwenguva refu.

Kana tiri kutaura nezve kutenga 32-50 inch TVs, saka zviri nani kutora FullHD. Ingori mhinduro yehupfumi, pairi pasina musiyano mukuenzanisa ne4K. Uye usanyengerwa nekuenzanisa muchitoro TV. Mushure mezvose, kunyengera kunoshandiswa ipapo - demo mode. TV imwe neimwe ine DEMO mode, apo kupenya uye kusiyana kunosarudzwa kuitira kuti mufananidzo wacho utaridze zvakanyanya. Nenzira, zviri nani kusatenga maTV akadaro kubva pahwindo. Hazvizivikanwe kuti vakashanda kwenguva yakareba sei pakukwanisa kwavo.

LED uye QLED - ndeipi yekutenga

 

Kana iyo bhajeti ichibvumira, zvirokwazvo QLED! Kunyangwe zvisingadhure mhando dzeChinese, QLED ine inotonhorera matrix kupfuura maLED kubva kuvatungamiriri vemusika maererano nemhando. Izvi zvinogona kuonekwa muchitoro, kunyangwe pasina DEMO modhi. Semuenzaniso, kana iwe ukatanga mafirimu ane rima zvirongwa "The Witcher" kana "Game of Thrones". Pane yakashata sensor (ine HDR pa), pachave neakasimba grey kana matema mavara pane yakasviba kumashure kwesango, zvivakwa kana zvinhu. Pane yakanaka matrix, nzvimbo dzakafanana) inoratidza zvidiki zvidiki, pasina halos uye kusanganisa neyakajairwa kumashure.

Kazhinji, iwe unogona kuita masvomhu kuverenga. Pano mushandi wehurumende akagadzirirwa makore 3-5. Uye maTV evatungamiriri vemusika achagara gumi kana kupfuura makore. Paavhareji, isingadhure 10-inch LED TV imadhora mazana mana, uye QLED imadhora mazana masere. Kana tikafunga nezvehupenyu hwekushanda, mari yacho yakafanana. QLED chete ine mufananidzo uri nani pane LED. Naizvozvo, kutenga TV ine quantum dots kunonyanya kunakidza pane midziyo ine yakare matrix.
