Gulu lowongolera ndilokhazikika, popanda zowonetsera zowonjezera, mapanelo okhudza kapena china chilichonse chonga icho. Makiyi abwino amakina akale okha, ndipo mawonekedwe awo amatsindika kwambiri pa Android TV - pali makiyi afupikitsa a Google Play, bwalo loyenda ndi kiyi yachidule ya Netflix yosapeŵeka. Kuwongolera kwakutali ndikosavuta, kosavuta komanso komveka.
Chosewerera chojambulidwa chomwe chimakupatsani mwayi kuti nonse musewere mafayilo kuchokera pagalimoto yakunja yolumikizidwa kudzera pa USB ndikuyiyika pamakumbukiro a TV. Mwa 16 GB yomwe idalengezedwa, 6,7 GB ilipo kwa wogwiritsa ntchito - simungathe kutembenuka ndi zomwe zili 4K, inde. Kukumbukira kumeneku kumafunikira makamaka kwa ogulitsa zida - tsitsani makanema owonetsera. Mndandanda wa ma codecs ndi wochuluka, mitundu yonse yofunika kwambiri ilipo.

Pakati pa zodandaula za TV iyi, zomwe sizimalola kulowa nawo gulu la "elite", tikuwona kusowa kwa chithandizo cha HDR10 + standard (HDR10 yokha) komanso kusowa kwa chithandizo cha HDMI 2.1 (zolowera zonse zinayi zimagwira ntchito ndi HDMI 2.0 - koma pali chithandizo chachitetezo cha HDCP 2.3). Ndizo zonse zonena.
Choyimira choyambirira chamagulu ndi Ultra HD (3840 × 2160). Dongosololi limagwira ntchito molimba mtima ndi zomwe zili patsamba lino, komanso likuwonetsa kuthekera kokweza bwino kwambiri. Chithunzi mu nkhani iyi pafupifupi palibe phokoso ndipo ndithu lakuthwa. Pa ma TV okhala ndi kusamvana kwakukulu, ndi ntchito yokhala ndi zithunzi zotsika zomwe zimatha kukhala chopunthwitsa - mtundu wa A8 ulibe zovuta zotere, kuphatikiza chifukwa chakugwiritsa ntchito ma organic LED - kuwerengeranso mtundu kumachitika pixel ndi pixel.
TV imagwiritsa ntchito purosesa yodziwika kale ya X1 Ultimate, yomwe, makamaka, imagwirizana bwino ndi kukonza HDR - zowoneka bwino zimawoneka zachilengedwe, ndipo phokoso lomwe nthawi zambiri limakhala pachithunzichi mumachitidwe awa siliwoneka. Zomwezo zikugwiranso ntchito pa chithunzi cha SDR chomwe "chatambasulidwa" ku HDR. Ukadaulo wa Super Bit Mapping umagwira ntchito bwino.
Ponena za kutsata gululo lokha ndi muyezo wa HDR10, palibenso zovuta pano. Kuwala kwakukulu kwa chithunzi chosasunthika choyezedwa poyesedwa (chipinda chowala kwambiri chokhala ndi kuwala kochita kupanga) chinali 778 cd/m2 (mawonekedwe okhazikika, kuwala kumafikira kupitilira apo). Palibe kukayika kuti gululo limafika pachimake cha 10 cd/m1000 chonenedwa mulingo wa HDR2 pogwira ntchito ndi zomwe zili zoyenera popanda vuto lililonse. Zosiyanasiyana zimakwaniritsidwa ndi gulu la OLED mwachisawawa. Ndizosatheka kuyankhula za kuwala kulikonse pokhudzana ndi gulu lamtunduwu. TV imalimbana ndi zomwe zingatheke ("kuwotcha mkati") kuchokera pazithunzi zosasunthika zokha, kusuntha pixel ya chithunzi ndi pixel nthawi ndi nthawi. Pasakhale vuto lililonse ndi izi.
TV imapereka makonzedwe angapo azithunzi nthawi imodzi: yowala, yokhazikika, kanema, masewera, zithunzi, chithunzi, mwambo, Dolby Vision yowala, Dolby Vision yakuda, mawonekedwe a Netflix calibration. Ndinayeza mtundu mumitundu yowoneka bwino komanso ya Cinematic, komanso mawonekedwe a Graphics, omwe ndi oyenera kugwiritsa ntchito PC.

Mawonekedwe a "Bright", m'malo mwake, amafunikira kuti muwonetse TV pawindo la shopu; itha kutchedwa mawonekedwe owonera. Chithunzicho ndi chowala kwambiri, chozizira kwambiri (kutentha kumapitirira 10 K), palibe funso la kulondola kwa mtundu, koma zonse zimawoneka zolemera komanso zowutsa mudyo momwe zingathere. Komanso munjira iyi mutha kuwona zowulutsa kapena masewera masana owala.

"Cinema mode" imagwiranso ntchito ndi malo ambiri amtundu (DCI-P3), koma imakhala yodekha (kutentha kwamtundu - 7 K). Kupatuka kwapakatikati kwa DeltaE kwa phale la Color Checker (mithunzi ya imvi + mitundu yosiyanasiyana yamitundu) ndi 100 - ndi yaying'ono komanso yokhululukidwa pamikhalidwe yomwe kuyezetsa kunachitika. M'mawonekedwe a Graphics, danga lamtundu ndilofala kwambiri (sRGB), kutentha kwamtundu kuli kofanana (zindikirani kuti mzerewo ndi wosalala momwe mungathere), ndipo kutembenuka kwa DeltaE pafupifupi ndi 4,22. Mwina sindingavomereze BRAVIA OLED A4,38 ngati chida chaukadaulo chogwirira ntchito ndi zithunzi, koma ngati mungaganizire kuthekera kosintha pamanja chithunzicho, mutha kuwona kuti gululo lidakonzedwa bwino.
Kugwira ntchito ndi zowonetsera zosiyana ngakhale pazithunzi zovuta kwambiri ndizosangalatsa - kusintha pakati pa kuwala ndi mdima wakuda ndikwabwino, palibe kuwala kotsalira. Phokoso la zida sizimawonekera mumdima. Muyezo wa Dolby Vision umathandizidwa, ndipo mapanelo a TV a A8 (ma diagonal onse) ali ndi mbiri ya IMAX. Ma angles owonera ndi aulere.

Sony BRAVIA OLED A8 ili ndi makina amawu a Acoustic Surface Audio, momwe chinsalucho chimasandulika kukhala oyankhula - ma drive apadera amaikidwa kumbuyo kwake omwe amanjenjemera, motero amatulutsa mawu kuchokera pachiwonetsero. Tekinoloje iyi imakwaniritsa malo omveka bwino kuposa kale lonse pamawu ophatikizana. Komanso, izi zikugwiranso ntchito pazomwe zikuchitika pazenera ndi kupitirira apo - dongosololi limayendetsa zochitika zotere mwangwiro. Ma acoustics, omwe ali ndi oyankhula awiri apamwamba / apakati pa 10 W aliyense ndi ma subwoofers awiri a 5 W aliyense, sangathe kudzitamandira ndi mphamvu zapamwamba, koma ndizokwanira kumveka chipinda chapakati. Ikapezeka mita imodzi ndi theka mpaka iwiri kuchokera pazenera, phokosolo limadziwika bwino. Sindinazindikire zolepheretsa zazikulu pamitundu yosinthika; ma frequency apamwamba komanso otsika amayendetsedwa bwino. Mwachidziwitso, iyi ndi imodzi mwamawu abwino kwambiri pa TV mu nthawi ya "flat panel" yomwe ndawonapo.
Pomaliza
- TV yokhala ndi ukadaulo wocheperako, ndipo izi ndizofunikira kumvetsetsa posankha. Amapangidwa makamaka kuti akhale gawo lofunikira m'bwalo laling'ono lanyumba - m'chipinda chapakatikati, chokhala ndi mawu owonjezera kapena opanda mawu (mawu omangidwa ndi abwino kwambiri). Kwa zisudzo zapanyumba zazikulu, diagonal ikhoza kukhala yosakwanira - kuchuluka kwachitsanzo ichi ndi mainchesi 65. Kwa malo ochitira masewera posachedwa, mawonekedwe a 4K/120p ndikugwira ntchito ndi HDMI 2.1 sizokwanira - komabe, kwa m'badwo wapano wa zotonthoza, kuthekera kwa TV ndikwabwino kwambiri: nthawi yoyankha ndiyabwinobwino, kuwongolera koyenda ndikwapamwamba kwambiri. .
Koma mkati mwa chimango chake, izi mwina ndizopereka zabwino kwambiri masiku ano. Kuwonera kanema pa Sony BRAVIA OLED A8 ndikosangalatsadi: ntchito yolondola kwambiri yokhala ndi mawonekedwe osiyanasiyana, mawonekedwe apamwamba kwambiri, kuthandizira HDR10 ndi Dolby Vision. Kuwala bwino kumakupatsani mwayi wodalira ma TV a A8 mpaka pamlingo wina ngakhale padzuwa lowala, zomwe sizingatheke nthawi zonse pa ma TV a LED - kotero zimakusangalatsani ngakhale mukugwira ntchito "pamlengalenga".
Tikuthokoza a Sony Center store chifukwa chothandizira kuyesa chipangizochi.
