Ingabe ngidinga ikhebula le-hdmi elikhethekile le-4k？
Okokuqala, sidinga ukucacisa ukuthi yini ekhethekile Ikhebula le-4k Hdmi yi. Nakuba izintambo ze-HDMI ezivamile zingadlulisela nezimpawu ze-4K, kunomehluko omkhulu ezintanjeni ezikhethekile ze-4K HDMI ngokuya nge-bandwidth, ukuzinza kwesignali, ibanga lokudlulisa, njll. Izintambo ezikhethekile ze-4K HDMI zivame ukuba ne-bandwidth ephezulu, zingasekela amazinga aphezulu ozimele kanye nokujula kombala, futhi zingafinyelela nokudluliselwa kwesignali okuzinzile emabangeni amade.
Kubadlali abaphishekela isipiliyoni sokudlala esiphelele, ikhebula le-4K HDMI elikhethekile lingaba yinto edingekayo. Namuhla, ama-console amaningi egeyimu esizukulwane esilandelayo asekela izindlela zemidlalo zesilinganiso sohlaka oluphezulu ku-4K resolution, njenge-120Hz noma ngaphezulu. Uma ubhekene nevolumu yokudlulisa idatha ephezulu kangaka, izintambo ze-HDMI ezijwayelekile zingase zibe nezinkinga ezifana nokugudlisela kwesithombe, ukubambezeleka okwandisiwe, ukuphambuka kombala, njll., okuthinta kakhulu ukushelela nokucwiliswa komdlalo. Ngobubanzi bayo obuhle kakhulu kanye namandla okucubungula amasignali, ikhebula le-4K HDMI elikhethekile lingaqinisekisa ukuthi isithombe somdlalo sivezwa kahle ngesilinganiso sohlaka oluphezulu, isinqumo esiphezulu kanye nokukhiqizwa kombala okuphezulu, okuvumela abadlali ukuthi basheshe ngesinyathelo esisodwa empini yomdlalo enamandla futhi bajabulele isipiliyoni somdlalo omnandi.
Uma abathandi bamafilimu nethelevishini befuna ukwakha indawo yokudlala yasekhaya yobungcweti ekhaya, ikhebula elikhethekile le-4K HDMI nalo libalulekile. Ama-movie e-Blu-ray e-4K namavidiyo okusakaza asezingeni eliphezulu avame ukuqukatha imininingwane eminingi kanye nolwazi olucebile lombala. Izintambo ezikhethekile ze-4K HDMI azikwazi nje ukuqinisekisa ukudluliswa okuzinzile kwamavidiyo e-4K, kodwa futhi zisekela ngokuphelele ubuchwepheshe be-high dynamic range (HDR), okwenza ingxenye ekhanyayo yesithombe ikhanye, ingxenye emnyama ibe mnyama, nombala ube sobala futhi ube ngokoqobo, okuletha abasebenzisi umphumela obonakalayo oshaqisayo njengenkundla yokudlala.
Kodwa-ke, izintambo ezikhethekile ze-4K HDMI azifaneleki kuzo zonke izimo. Uma isimo sakho sokusetshenziswa silula, vele ubukele amavidiyo ajwayelekile aku-inthanethi ngezikhathi ezithile nge-TV ye-4K, noma uxhume ikhompyutha yakho kusikrini se-4K somsebenzi wansuku zonke wasehhovisi, intambo ejwayelekile ye-HDMI ingahlangabezana nezidingo zakho ngokugcwele. Ngenxa yokuthi okuqukethwe okuningi kwamapulatifomu evidiyo aku-inthanethi kunqunyelwe umkhawulokudonsa kanye nokuvikelwa kwe-copyright, ukulungiswa kwangempela kanye nesilinganiso sohlaka akufinyeleli ekusebenzeni okuphezulu kakhulu kwamadivayisi e-4K, izintambo ezijwayelekile ze-HDMI zanele ukudlulisa lezi zimpawu ngokuzinzile, futhi ngeke kube khona ukulahleka kwekhwalithi yesithombe okusobala noma ukuthuthumela. Ngokufanayo, izimo zasehhovisi zansuku zonke azinazo izidingo eziphezulu zesilinganiso sohlaka kanye nokujula kombala wesithombe, futhi ukusebenza kwezintambo ezijwayelekile ze-HDMI kungaphezu kokwanele.
Ngaphezu kwalokho, intengo yezintambo ezikhethekile ze-4K HDMI ivame ukuba phezulu kakhulu kunezintambo ezivamile ze-HDMI. Uma isabelomali silinganiselwe futhi isimo sokusetshenziswa singenazo izidingo eziqinile zekhwalithi yesithombe kanye nokusebenza kokudlulisa, ukukhetha ikhebula elivamile le-HDMI ngokungangabazeki kuyisinqumo esingabizi kakhulu.
Esiteshini sethu esizimele, akukhona nje kuphela izinhlobo ezahlukene zezintambo ze-HDMI ezivamile ongakhetha kuzo, kodwa futhi nezintambo ezikhethekile ze-4K HDMI zemininingwane ehlukahlukene ukuze kuhlangatshezwane nezidingo zabasebenzisi abahlukene. Umkhiqizo ngamunye uhlolwa ngokuqinile ikhwalithi ukuqinisekisa ukuzinza nokuthembeka kokudluliswa kwesignali. Kungakhathaliseki ukuthi ekugcineni unquma ukuthi udinga ikhebula elikhethekile le-4K HDMI, singakunikeza ukubonisana komkhiqizo ochwepheshe kanye nezinsizakalo zokuthenga ezisezingeni eliphezulu ukukusiza ukuthola ikhambi le-HDMI elifanele kakhulu kuwe futhi uqale uhambo oluhle kakhulu lwe-HD audio-visual.
