Ubwubatsi nijwi

4S na 4A bifite umubiri ugezweho ariko gakondo, ushyizwe kumaguru abiri yagutse cyane yakozwe mubyuma. Intera iri hagati yamaguru ntishobora guhinduka. Ibyuma bya matte bikikije ecran biha TV isura nziza, mugihe ikirangantego cya Mi cyerekanwe cyashyizwe hagati ya bezel yo hepfo gishimangira ibitekerezo byiza byibicuruzwa biharanira kwigaragaza mubyiciro byayo. Urukuta rw’inyuma rw’urubanza rukozwe mu cyuma gikomeye, ariko igifuniko cyo hagati hamwe n’igifuniko cya disikuru bikozwe muri plastiki. Muri rusange, ubwiza bwibikoresho nibyiza, kandi TV (cyane cyane imbere) itanga igitekerezo cyibicuruzwa bihenze cyane.
Hano hari abavuga babiri – buri wese afite imbaraga za watts 8. Bakora bate? Ijwi rito riragoye cyane gutandukanya, ariko ibi ntibitangaje, hafi TV zose ziri muriki cyiciro cyibiciro ntizibyara imirongo mike. Kurundi ruhande, amajwi muri treble na midrange aratengushye – bisa nkaho bigoretse gato, bityo “tinny” kandi biringaniye.

Sisitemu nubuyobozi

Uruganda rwongeyeho igicucu cyarwo cyitwa PatchWall kuri Android 9. Irashobora gufungura hamwe na buto idasanzwe kuri kure ya kure cyangwa kuva kuri menu nkuru. Ariko ku isoko ryacu ntabwo rihari. [ibisobanuro id = “umugereka_10183” align = “aligncenter” ubugari = “776”]
Imashini ya PatchWall yashyizwe kuri TV zose zigezweho za Xiaomi [/ caption] Bitandukanye na TCL irushanwa, nayo ikoresha TV ya Android, Xiaomi ntabwo yabitse kubitunganya no kwibuka. Turabikesha, software ya TV ikora neza cyane, kurugero, TCL EP717 cyangwa ndetse na EC728 ihenze cyane. Ariko, “ibyiza” ntibisobanura “gutungana”. Sisitemu ikunda kugenda gahoro gahoro – haba kurwego rwa menu yo kugendana (gake cyane) cyangwa imbere muri progaramu ya progaramu (kenshi cyane). Kwihangana birasabwa cyane cyane mubihe byanyuma, kuko “gukonjesha” porogaramu irashobora gufata amasegonda menshi, kandi rimwe na rimwe ugomba gukuraho cache yikibazo giteye ikibazo. Inyongera nziza ni nini kandi yoroshye kugenzura kure. Iki nigikoresho cyakozwe neza gikoresha umurongo utagira umurongo ukoresheje Bluetooth, kubwibyo, ntibisaba guhora “kwerekana” kubakira IR. Kubwibyo, Xiaomi akwiye inyongera nini.

Ubwiza bwibishusho, HDR nuburyo bwimikino

Ubwiza bwibishusho ntabwo butandukanye cyane nibyo abanywanyi batanga muriki giciro. Ibara ryibara rya palette ya DCI P3 rirenga 64% gusa (ugereranije, 55-TCL EP717 ya santimetero 55 hamwe na VA panel igera kuri 66%), kandi ishusho ubwayo irakungahaye bihagije kugirango ushimishe abakoresha badasaba. Igishimishije, impande zo kureba ntabwo ari nini nkuko bisa nkibiranga akanama gakoreshwa. Nyamara, ibi ntibiterwa gusa nibipimo bya matrix ubwayo, ariko nanone biterwa nigiciro gito ugereranije cyurumuri rwinyuma rwa ecran hamwe nigitambaro cyakoreshejwe – guhuza ibi bintu bitatu bivuze ko mubisanzwe, kumanywa, ubwiza bwa ishusho igaragara kumurongo itandukanye nibyifuzo byabakoresha. Kubera ko tuvuga kumurika, agaciro kayo mugice cyo hejuru kigera kuri 260 cd / m ^ 2, hamwe byemewe, hejuru ya 9% yumucyo utaringaniye, biterwa ahanini na tekinoroji ya LED yamurika. Birakwiye ko tumenya ko uburyo bwamashusho bwatoranijwe gusa bukoresha agaciro kuzuye k’urumuri rwinyuma (kurugero, uburyo bwa “Bright”) – hamwe nibice byinshi (urugero, “Bisanzwe”, “Imikino” cyangwa “Filime”), urwego rwurumuri ntirenza 200 cd / m ^ 2, ariko birumvikana ko agaciro kayo gashobora kwiyongera nintoki. Muburyo bwa HDR (ibyo Xiaomi Mi TV 4S ishyigikira mubyukuri) ntabwo aribyiza. Mugihe cyo hejuru, ecran irashobora kugera kuri 280 cd / m ^ 2 gusa, ibyo ntibihagije kugirango HDR igaragare neza, ariko nibindi byinshi kuri tekinoroji nyuma gato. Ibintu ntabwo byahinduwe neza nuko TV ishyigikira gusa “shingiro” HDR10 isanzwe, kubijyanye na ecran “yijimye” ntacyo itanga. Mu gusoza iki gika, hasigaye kongeraho ko sisitemu idashyigikira HDR kuri YouTube.
