Nenzira, tsika dzekombiyuta dzave dzakakosha pane mamwe magetsi emusha kana zvasvika pakugadzirisa. Izvi zvakatanga kushandura kana terevhizheni yakakwirira yakaiswa kune vatengi uye pakupedzisira yakagamuchirwa nehurumende nevashambadziri. Iye zvino maHTTV uye vatariri vakawanda vepakombiyuta vanogovera sarudzo imwe chete asi makombiyuta emafoni akawanda aripo anouya akashongedzerwa nezviratidzo zvezasi. Izvi zvakashandura zvishoma pashure pekunge Apple atanga kusunungura Retina yavo yakatarisa asi asi iye zvino nemagetsi ekupedzisira 4K kana UltraHD, vatengi vanogona kuwana zviratidzo zvinopa mamwe mazwi asinganzwisisiki kupfuura kare. Pane zvimwe zvinoreva kana iwe uchifunga nezvokuwana nekushandisa kuratidzwa kwe 4K nekombiyuta yako.
Chii chinonzi 4K kana UltraHD?
4K kana UltraHD sezvo inonzi yakatumidzwa zvakashandiswa inoshandiswa kureva kirasi itsva yepamusoro-soro terevhizheni uye vhidhiyo. Iko 4K iri kureva kurongeka kwakakwana kwechifananidzo chechifananidzo. Kazhinji, zvinenge 3840x2160 kana 4096x2160 zvisarudzo. Izvi zvinenge kaviri nguva yekugadziriswa kwemazuva ano HD maitiro anobuda kunze muna 1920x1080. Kunyange zvazvo zviratidzo izvi zvinogona kuenda zvakanyanya kwazvo, vatengi vane kambani kadiki yekutora mavhidhiyo 4K kune mazviratidziro avo sezvo pasina hurumende yakashambadzirwa yakatarwa iyo muUnited States uye vatambi vekutanga 4K Blu-ray vachangobva kuitengesa kutengesa.
Nevhidhiyo yeD 3D isingatoreri mumakiti emitambo yemusha munyika yose, vataki vava kutarisa UltraHD senzira yekusimudzira chizvarwa chinotevera chemagetsi eimba kune vatengi. Iko kune nhamba huru yevhevhizheni 4K kana UltraHD inowanikwa mumusika uye PC maonesheni ariwo kuve akawanzoita kuma desktops uye kunyange akabatanidzwa mune mamwe mapepa ekupedzisira. Kushandisa zviratidzo izvi kune zvimwe zvinoda, zvakadaro.
Video Connectors
Rimwe rematambudziko ekutanga ayo makombiyuta achange achiedza kumhanya vatariri ve 4K kana UHD vari kuzova vhidhiyo yevhidhiyo. Izvo zvakasarudzwa zvikuru zvinoda huwandu hwakawanda hwomukati wechipfuva kuitira kuti utumidze dheedhi inodiwa yevhidhiyo yevhidhiyo. Matayendisiti akare akadai saVGA neDVI haakwanisi kutora matanho iwayo akavimbika. Izvi zvinosiya maviri mapurogiramu ekupedzisira evhidhiyo, HDMI uye DisplayPort . Izvo zvinofanira kuonekwa kuti Thunderbolt inotsigirawo zvigadziriswa izvi sezvo ichibva paTexPP teknolojia nekubatanidza kwezviratidzo zvevhidhiyo.
HDMI inoshandiswa nevose vashandisi emagetsi uye zvichida ichava iyo inonyanya kurudzirwa yehutano uhwu uhwo huchaona pamatambo makuru ma 4K HDTV vatariri pamusika. Kuti ikombiyuta ishandise izvi, kadhi yevhidhiyo ichada kuva neHTMLMI v1.4 inoshandiswa. Pamusoro peizvi, iwe uchadawo HDMI High Speed yakarongwa tambo. Kukundikana kuva nemakumbo akanaka kunoreva kuti chifananidzo hachikwanise kuendeswa kuchikwangwani pahugadziriswa zvakakwana uye ichadzokera kumashure ekudzika. Pane imwe nyaya shomanana inobudiswa ye HDMI v1.4 uye 4K video pamwe chete. Iyo inokwanisa chete kutumira chiratidzo ne 30Hz yekuvandudzwa kwemafuro kana mapurisa makumi matatu pamasere. Izvi zvinogona kugamuchirwa kutarisa mafirimu asi vazhinji vashandisi vepakombiyuta, kunyanya vatambi, vanoda kuva ne 60pps. Izvo itsva HDMI 2.0 tsananguro inogadzirisa izvi asi ichiri kuwanzoonekwa muma PC akawanda mawonesi makadhi.
DisplayPort ndiyo imwe sarudzo inogona kushandiswa nekombiyuta dzakawanda uye ma kadhi evhidhiyo. NeChiratidzoPort v1.2 tsananguro, chiratidzo chevhidhiyo pamusoro pechirongwa che hardware chinokwanisika chinogona kukwanisa kuzadzisa 4K UHD signal yevhidhiyo kusvika ku 4096x2160 uye yakadzika uye 60Hz kana mapuranga pamasekondi. Izvi zvakakwana kune vashandisi vekushandisa kombiyuta vanoda kuwedzerwa kwekuvandudza tsananguro yekuderedza kushungurudzwa kwemaziso uye kuwedzera kufanana kwekufamba. Izvo zvakaderera pano ndezvokuti pane zvakawanda zvakawanda zvevhidhiyo kadhi hardware kunze uko iyo isina DisplayPort version 1.2 mazambu akabatanidzwa. Izvi zvinogona kureva kuti iwe uchadikanwa kuti uvandudzire kune kadhi kadi yekare iyo iwe unoda kushandisa imwe yezviratidzwa zvitsva.

Nekombiyuta yakawanda ikozvino uchishandisa 1920x1080 yakakwirira-tsanangudzo kuratidza mazano kana kuti pasi, pakange pasina kudiwa kukuru kwekadhi yemafadhi e-graphics. Zvose zvine mavara mapurogiramu angave akabatanidzwa kana akazvitsaurira anogona kubata hurukuro yevhidhiyo mumabasa matsva 4K UHD. Nyaya iri kuuya nekumhanya kwevhidhiyo yevashandisi ve 3D. Pakawanda nguva yekugadziriswa kwemashoko akaenzana akareba, izvo zvinoreva katatu kuwanda kwemari inoda kuongororwa nekadhi rakagadzirwa . Mazhinji emakadhi evhidhiyo anenge aripo haazokwanise kusvika pazvisarudzo izvi pasina matambudziko makuru ekushanda.
PC Pfungwa yakabatanidza pamwe nenyaya huru iyo yakatarisa kushanda kweiyo video makadhi hardware achiedza kumhanya mimwe mitambo paTV yeTVM. Vakaona kuti kana iwe uchida kunyange kutamba mitambo pamapfumi akareruka makumi matatu nemasere, iwe unofadza zvikuru unotengwa kutenga kadhi kadiki inodhura inopfuura $ 500 . Izvi hazvishamisi zvikuru sezvo aya ndiwo makadhi anonyanya kudiwa kana iwe wakaronga pakushanda vatariri vakawanda kuti uwane kuratidzika kwekuratidza. Nhamba yakawanda yakawanda inoratidza kuiswa kwevheeri kune zvitatu 1920x1080 zvinoratidza kubudisa 5760x1080 image.
